With an extensible architecture, Digital Signal Processor (DSP) resources are allocated consistently in the next generation of MSR series routers. This brings higher DSP


2-2

resource utilization and access density. At the same time, local TDM switching is supported. On the one hand, voice quality is guaranteed. On the other hand, DSP resource occupation resulted from local calls is avoided and DSP resources are saved.

The next generation of MSR series routers provide flexible pinch card design. You can select it if necessary.

III. Security

Today, security becomes the basic function of a network. It is necessary to integrate security into the overall network. So a router plays an important role in network defense strategies. The next generation of MSR series routers can provide security services in conjunction with other services applications for its advanced, integrated and end-to-end security.

Comware V5 has extended security features further. Available security functions include Firewall, IPSec VPN, MPLS VPN, CA, Secure Shell (SSH) protocol 2.0, intrusion protection and simple network management protocol (SNMP v3) and so on.

Since security is directly integrated into the routers, the next generation of MSR series routers have a lot number of security accelerator hardware, including encryption function from hosts as well as MIM/FIC modules and ESM encryption engine for encryption.

IV. Balanced services and performance

The next generation of MSR series routers can provide users data, security, voice and video integrated services and upper layer applications, meeting their applications on the Internet at present and in the future without compromising original data transfer performance.

2.2 New Storage Media

The next generation of low-end and mid-range routers supports the use of new storage media like USB Flash and CF card for flexible scalability and investment protection. At the same time, many simple and convenient means are available for security and automatic service implementation.

2.2.1 USB

USB, the short of Universal Serial Bus, supports connecting several devices with a rate higher than common parallel ports and serial ports. There are two specifications of USB: USB 1.1 and USB 2.0, with up to 12Mbit/s and 480Mbit/s rates respectively. . USB is hot-swappable and plug-and-play.

Now, MSR 20/30/50 series routers support USB 1.1. With it, you can enjoy mission-critical storage and security functions, for example, provide a lot of Flash


2-3

memory for applications and configuration, store security VPN certification to build a secure VPN connection and distribute configuration safely.

I. USB Flash memory

USB Flash memory is attained to the router through a USB interface and can be detected automatically for plug-and-play. You only need to insert it in the USB interface of the router. USB Flash memory provides a choice of standby storage function. Comware software mirroring, configuration or other files can be replicated to USB Flash memory, and also then replicated to the router. As for reliability, it is compared to using CF (Compact Flash) card to save and recover files.

When it comes to supported file formats, USB Flash memory supports all the file formats supported on CF card (FAT16, FAT32). The configuration can be transferred from USB Flash memory to the router automatically for automatic configuration and deployment.

Huawei-3Com supports the following kinds of USB Flash memories: 64MB, 128MB, 256MB and 512MB.USB Flash memory provides a mechanism of backing up CF card. As USB Flash memory is widely used, using it to backup and recover files can bring in higher convenience and reliability for users.

II. USB application

With the introduction of USB interface, you can save the configuration of the router in USB Flash memory. After you insert the USB Flash memory holding the configuration in the USB interface, the router can get the configuration from the USB Flash memory, and then upgrade and update automatically. In this way, you can realize “zero-touch configuration and implementation.” That is, enterprises and carriers can upload boot configuration into the USB Flash memory. With the help of boot configuration, a remote site can build a connection to the master site, and then download the complete configuration to carry out deployment.

By leveraging the mentioned USB features, enterprises and carriers can carry out deployment over a network without uploading the configuration to routers before delivery and deployment, so as to realize low touch or zero touch configuration and deployment. In addition, manufacturers can ship routers to customers directly without configuration. As a result, the products can close the real requirements of customers for easy of use.

2.2.2 CF Card

Compact Flash Card (CF card), an advanced mobile storage, features high speed, high capacity, compact factor, light and low power consumption.

MSR 20/30/50 series routers support CF card. You can upgrade and replace CF card without opening the chassis. As for easy of use, it represents a design vision of personalization. As the software features and services of routers are changing, the size


2-4

of Comware V5 software platform is increasingly growing. A design to fix storage capacity is a risk and obstacle for software upgrading. Use of CF card can solve this issue. You can protect investments perfectly and provide ongoing service scalability for users.

2.3 Routing & Switch Convergence

SIC/MIM slots in the next generation of MSR series routers support many kinds of Layer 2 switching modules. In which MSR 30 series routers support 4/8/16/24-port SIC/DSIC/MIM/DMIM switching modules. Coupled with feature-riched switching of Comware V5 software platform, the next generation of MSR series can ensure comprehensive routing and switch convergence.

The Ethernet switch modules of the next generation of MSR series routers are capable of realizing Layer 2 switch LAN interface-to-Layer 3 WAN interface conversion. In case of access to Ethernet, up to four Layer 3 WAN interfaces can be configured to facilitate flexible networking.

The Ethernet switch modules of the next generation of MSR series routers allow for perfect Layer 2 Ethernet switch features and related protocols, for example, VLAN, MAC address management, STP, port aggregation LACP, 802.1x and QoS/ACL and so on. Where SIC/DSIC cards are designed to implement low density access switches that provide basic Layer 2 switch feature; MIM/DMIM cards are designed to implement high density access and aggregation switches that provide intelligent and scalable Layer 2 switch feature. MIM/DMIM cards are hot-swappable. DMIM card comes with photoelectric Combo GE interface to enable access in different distances. At the same time, GE interface interconnection can be used to realize expansion of ports and VLAN domain between modules.

Plug-in cards with different densities and different features can adapt to different user requirements while streamlining networking. Multi-services routers work well when switch modules enable L2 wire speed forwarding, meeting the requirements of routing and switch integration and replacing the networking of traditional routers and Ethernet switches in deed. As a result, users can use and manage devices flexibly.

2.4 IPv6

Today’s Internet is running on the basis of IPv4 protocol. With the rapid development of the Internet, limited address space defined by IPv4 will be exhausted. Short of address will make an adverse effect on the continuous development of the Internet, and severely restrict the application of IP technologies and the prospect of networks in the future. IPv6, as the basis of the next generation of networks, is broadly recognized for its outstanding technical advantages, which are shown as follows:.

l Flexible header format l Larger address space


2-5

l Valid hierarchical addressing and routing system l Full state and stateless address configuration l Built-in security l QoS l Robust negotiation mechanism for neighbor discovery l Scalability l Meeting mobile requirements (3GPP determined to use IPv6 to build the next

generation of IPv6 core network)

The next generation of MSR series routers support the following IPv6 features:

l IPv6 address l Local link unicast address l Local site unicast address l Global unicast address l Multicast address l IPv6 Neighbor Discovery l Neighbor Discovery (ND) host l Neighbor Discovery (ND) router l IPv6 Path MTU l IPv6 ACL l IPv6 routing protocol l IPv4 to IPv6 migration l Network Address Translation-protocol Translation) NAT-PT l Packet and message translation l IPv6-IPv4 tunneling

2.5 A Rich of Interfaces

The next generation of MSR series routers come with a rich of physical interfaces. General interfaces include: syn/asyn serial interface, Ethernet interface, E1/T1 interface, E1-F/T1-F interface, E3/T3 interface, ISDN BRI/PRI interface analog modem (AM) interface, voice interface, SDH interface and Ethernet port and so on.

l Ethernet interfaces: FE and GE; l Frame relay interfaces: E1/T1, E1-F/T1-F, syn serial interface, E3/T3; l X.25 interfaces: E1/T1, E1-F/T1-F, syn serial interface, E3/T3; l ISDN interfaces: ISDN BRI, ISDN PRI; l PSTN interfaces: asyn serial interface, E1/T1, AM, ADSL2+; l DDN network interfaces: syn/asyn serial interface, E1/T1, E1-F/T1-F, E3/T3; l Voice interfaces: analog voice interfaces (including FXS/FXO/E&M), digital voice

interfaces (including VE1/VT1); l USB interface: USB 1.1; l Layer 2 Ethernet ports; l POS interface.


2-6

2.6 Feature-riched Services

The next generation of MSR series routers provide a large number of services as follows:

I. xDSL

The next generation of MSR series routers have an optional SIC-ADSL2+ interface card. SIC-ADSL2+ offers common phone interfaces. By leveraging digital code modulation technology, you can access digital subscriber line access multiplexer (DSLAM) devices through the existing copper phone lines and obtain higher data transmission capacity.

With ATM adaptation layer 5 (AAL5) as the ATM adaptation layer protocol, the next generation of MSR series routers provide traffic services like constant bit rate (CBR), variable bit rate (VBR) and unspecified bit rate (UBR). Many issues, such as IP packet over ATM, authentication and accounting, are also solved through IPoA, PPPoA and PPPoEoA technologies. This series of routers is applicable to high speed data services and transmission of larger data packets, helping small- and medium-sized enterprises networks to access the Internet directly through broadband.

II. MPLS VPN and traditional VPN

The next generation of MSR series routers support Layer 2 and Layer 3 tunneling protocols. Layer 2 tunneling protocol (L2TP) is helpful for users to enable dial-in virtual private data network (VPDN) and leased-line VPN services. Layer 3 tunneling protocol is enabled based on generic routing encapsulation (GRE) protocol. Combined with IPSec technology, it provides a full set of network security solutions for leased-line VPN, including access control, connectionless integrity and data source authentication, anti-replay, encryption and traffic classification and encryption. Both tunneling protocols can be used independently or jointly to provide better services.

MPLS is the combination of IP and ATM. It uses a short, fixed long label to replace IP header to identify data flows and as the basis of forwarding to provide higher forwarding rate. With the support of IP routing protocol and control protocol, MPLS can meet the network requirements of diverse new applications. In a MPLS network, tagged packets are transferred along the label switched path (LSP) made up of a series of label switch routers (LSRs). Using MPLS to enable VPN is of natural advantages because LSP itself is a tunnel on the public network. MPLS VPN refers to combine the geographical branches of a private network into a unified network. It supports the reuse of IP addresses between branches and interoperation between VPNs. MSR 20/30/50 series routers can function as not only label edge routers (LERs) but also label switch routers (LSRs). When MSR 20/30/50 series routers locate at the edge of a label domain, they as LERs can connect MPLS domains and non-MPLS domains as well as different MPLS domains, and classify services, distribute labels, encapsulate or strip off


2-7

multi-tier labels. When the next generation of MSR series run in a MPLS domain, they can exchange labeled packets.

III. DCC

The next generation of MSR series routers bring perfect dial-in solutions for users, with Circular DCC and Resourced-Shared DCC two dial-in modes supported. In some cases, a connection is built and communication is carried out between routers only when there are messages need to transfer. So the transferred messages are time-free, small in volume and unexpected. DDC comes into being to offer a flexible and cost-effective solution for users. Especially, Resource-Shared DCC is more perfect. It allows more than one dial-in user to share physical interfaces and make different calls through dialer pool. In real circumstances, DCC generally is used in backup mode to guarantee the master line communication. When the master line cannot communicate services due to a line failure or other reasons, DCC provides a backup line to guarantee the operation of services. In addition, DCC can enable callback, including PPP callback, ISDN calling line identification callback.

IV. Voice

The next generation of MSR series routers provide mainstream voice communication protocols like H.323 and SIP for a variety of voice services such as emergency call/dial-in policy/fax/E-PHONE, and a variety of voice interfaces such as FXS/FXO/VE1/VT1/E&M.

By employing high performance digital signal process (DSP) chipset and high compression ratio coding/decoding algorithm, combined with the features from Comware V5 software platform like security, QoS and policy-based routing, the next generation of MSR series routers can ensure the transmission of voice over IP through silence compression, comfortable noise and anti-jitter measures.

Two connection modes are supported: quick connection and non-quick connection. The next generation of MSR series routers carry out out-band transmission of dual tone multi-frequency (DTMF) codes with tunneling while offering busy tone detection and some special services for PBX (for example, Do-Not-Disturb, transfer in busy and alarm clock).

Voice processing module (VPM) is also supported. It is a DSP array and easy of upgrading and expansion. All VE1 and VT1 interface cards share DSP resources of VPM, saving user investments and maximizing hardware resources.

The next generation of MSR series routers provide a rich of voice interfaces that can not only directly connect to general phones/faxes, but also connect to PBX switches through trunks like AT0 and E1/T1. It realizes the interoperation with voice gateways from other vendors well in addition to high density and qualified voice and fax communications, protecting the existing investments of users effectively. When E1 trunk is used to connect a PBX, R2 signaling as well as DSS1 and Q.SIG signaling on ISDN PRI interface are supported. One-stage/dual-stage dial-in services are available.


2-8

Synchronous transmission of voice and data on PRI interface is also supported. As a result, the utilization is improved and the scope of supported services is enlarged.

The next generation of MSR series routers offer Gateway Keeper (GK) Client function that maintains communications with GK Server through Registration, Admission and Status (RAS) signaling. In this way, GK Server provides H3C voice gateway services like access permission, address translation, bandwidth management and voice gateway management. At the same time, it can network with mainstream voice gateway flexibly. This makes the next generation of MSR series routers fit for large- and medium- sized voice communications in enterprises.

By compressing redundant information like voice header on low-speed PPP serial links, IP Header Compression (IPHC) reduces the bandwidth occupied by voice channels significantly and maximizes network resources.

The next generation of MSR series routers provide voice RADIUS function. When a voice call occurs, the router reports statistics including call duration, number of packets and number of bytes to RADIUS Server for accounting.

2.7 Powerful Forwarding/Service Processing

IP packet forwarding efficiency is a key index for performance measurement. When the router forwards a packet according to general procedure, it needs to look up the routing table based on the network layer information of the packet to determine a best path for forwarding. And each subsequential packet will be processed by this process repeatedly. In addition to flexible services and protocol processing, the next generation of MSR series routers use advanced quick route search algorithm to enable fast forwarding, improving forwarding and services processing capabilities significantly. The next generation of MSR series routers support fast forwarding on a variety of high speed link interfaces. It can also forward packets rapidly in conjunction with QoS and firewall.

2.8 High Reliability

I. Hot-swappable power supply/interface card/fan

According to carrier-class product requirements, the next generation of MSR series routers are designed to support RPS redundant power supply, so as to meet the high reliability requirements of carrier-class networks on devices.

II. Backup center and VRRP

With Backup Center and VRRP, the next generation of MSR series routers provide a backup solution in case of a communication line or device failure to guarantee smooth data communication, and thus boosting network robusticity and reliability effectively. Backup Center supports backup load balancing.


2-9

III. External storages like CF card and USB Flash memory

CF card and USB Flash memory can be used to store many system files and configuration to improve system reliability. External storages can accommodate a large volume of system logs and security logs for backing up, browsing and archiving.

2.9 Superior QoS

The next generation of MSR series routers are developed based on Comware V5 platform. The QoS of V5 platform inherits all the QoS features of previous Comware versions. That is, it supports Diff-Serv standard well. At the same time, it adds the supports of IPV6 QoS as well as MPLS Traffic Engineering (MPLS TE) and MPLS Resource Reservation Setup Protocol (MPLS RSVP).

QoS Diff-Serv model includes traffic classification, traffic policing, traffic shaping, queue management and queue scheduling that completely enables six sets of PHB services (EF, AF1 to AF4, BE) defined in standards. This allows network operators to provide users different QoS levels of service guarantee, making the Internet a real data, voice and video integrated network.

The enablement of Differentiated Service (Diff-Serv) includes traffic classification, traffic policing (CAR), traffic shaping (GTS), congestion management (PQ/CQ/WFQ/CBQ) and congestion avoidance (WRED).

l Traffic classification: identify interesting objects by a certain matching rule. Traffic classification is the premise for differentiated services.

l Traffic policing: monitor the specifications of the specified traffic flowed into the router. Once the traffic has exceeded the specifications, you can take restriction or punishment actions to protect the business interests and network resources of operators.

l Congestion management: measures you must take to settle resource competition in case of network congestion. Generally, it places packets in a queue for caching and uses a scheduling algorithm to determine the forwarding order.

l Congestion avoidance: too congestion may damage network resources. Congestion avoidance monitors the utilization of network resources. When it finds that the congestion is aggravating, it drops packets proactively and relieve network overload by adjusting traffic.

l Traffic shaping: a traffic control measure that actively adjusts the traffic output rate. Generally, it is used to adapt to the available network resources from the downstream routers and avoid unnecessary packet drop and congestion.

MPLS traffic engineering (MPLS TE) is a QoS technology based on Int-serv module. By combining traffic engineering and MPLS, you can establish a LSP tunnel to the designated path and reserve resources. So network traffic can bypass congested nodes for the purpose of balancing. The next generation of MSR series routers can use QoS in a MPLS network flexibly. Furthermore, it can use original QoS of Diff-Serv for


2-10

CE and PE routers and QoS of Int-Serv for MPLS aggregation/core networks to realize real end-to-end QoS guarantee.

2.10 Perfect Security Mechanism

The next generation of MSR series routers have many authentication methods (plain text authentication and MD5) and support two kinds of user authorization modes: local authentication and RADIUS authentication that can authenticate user IDs and authorization to prevent from illegal configuration of devices.

The ACL feature of the next generation of MSR series routers is used to create a combination of rules that permit or deny based on source/destination IP address segments (including host address) or source/destination ports. This is applicable to the following cases where you can control access to the traffic on the user side or the network side and set the rights to access local information network or WAN by users for the purpose of protecting key servers, protecting system users, restricting foreign access, preventing from network attacks and supporting real-time updating.

The network address translation (NAT) feature of the next generation of MSR series routers allows for translation and recovery of IP addresses and ports. At the same time, it allows the Intranet to provide limited access to internal hosts by user configurations. The feature can also meet high capacity and high performance to adapt to the position of the next generation of MSR series routers in a network. In addition to above mentioned basic functions, the NAT feature of the next generation of MSR series routers limits the number of concurrent connections of individual users. As a result, it can reduce network strike from malicious resource occupation while meeting general network applications. You can output address translation information through logs to analysis network failures and locate hidden security troubles. The NAT feature provides application layer gateway (ALG) function for common specific application layer FTP and ICMP.

Furthermore, H3C MSR 50 series routers have plenty of statistics including traffic statistics, traffic sample and NAT information statistics.

2.11 Robust Route Policy

Route policy consists of a series of rules which are broken into three types used for route publication, route receiving and route import respectively. Route policy is referred to as route filtering, because defining a policy is equivalent to defining a set of filters and applying these filters before the receiving/publication of a route information or the exchange of route information between different protocols.

Route policy is used with routing protocols to strengthen the control of routing protocols. When exchanging route information with the peer, a upper layer routing protocol may need to only receive or publish a part of route information meeting the specified conditions; when importing the route information of other routing protocols, the route


2-11

protocol may need to only import a part of route information meeting the conditions, and set some attributes of the imported route information to satisfy the requirements of the protocol. Route policy is the way to enable these functions for route protocols.

Route policies supported on the next generation of MSR series routers including route policy definition, route import and distribution definition and restriction rules like route prefix, autonomous system path, community attribute and access list. The use of route policy is of greater practical value for the manageability of enhanced a network.

2.12 Integrated Network Management System

Quidview V3 is the next generation of network management system self-developed by Huawei-3Com. With componentized structure design, Quidview enables lots of functions like device management, VPN monitoring and deployment, software upgrade management, configuration management, alarm management, performance management and WEB report through the installation of different service components. Quidview provides a perfect solution to facilitate monitor, maintain and manage your networks, no matter you are enterprise network user, campus networks users or operators.

In case of independent installation, Quidview device management components can integrate with common network management platforms in the industry, for example, SNMPc, HP Openview.

The next generation of MSR series routers have many maintenance means like local maintenance, remote maintenance and centralized maintenance, and provide a full set of alarm, test, diagnosis, trace and log functions for daily maintenance and management.

2.13 Globalization Design

According to UL, CE and FCC standards, the next generation of MSR series routers are designed to conform to certification requirements in home, Europe and North American.

Figure 5-3 Network application in carriers’ networks or large networks

H3C NE series high-end and core routers are used in the core to form a backbone ring network. NE40, NE16E and NE08E can function as core routers. 155M POS or GE links are used in the backbone. At the same time, dual devices are used in each stage for higher reliability of backbone.

MSR 20/30/50 series routers are used on the aggregation layer and the access layer to access the networks on the corresponding layers. These devices use 155M, 100M Ethernet and 2M lines as their communication links.

Other high-end, mid-range and low-end devices from H3C are used as switches and firewall in the network.

5.4 IPv6 Network Application

The next generation of MSR series routers provides a full support for IPv6, one of its important features. To protect user investments and the compatibility with the existing IPv4 networks, IPv4 is also supported. With dual-stacking technology, the next generation of MSR series routers can ensure the concurrent operation of pure IPv4 devices and pure IPv6 devices in a network properly. The following figure is an IPv6 network application.

MSR 50 series routers with IPv6/IPv4 dual-stacking technology are used in the headquarters and MSR 20/30 series routers are used in branches. You can use IPv4 independently or IPv6/IPv4 dual-stacking technology for networking. For network communications from IPv6 to IPv4, tunneling also can be used to realize seamless communications between IPv6 and IPv4 networks.

5.5 MPLS VPN Network Application

The next generation of MSR series routers supports MPLS VPN technology that can be used to build a network. H3C NE series high-end and core routers and MSR 50 series routers are used in the headquarters; H3C MSR 20/30 series routers are used in branches or partners’ networks. . NE series routers can function as P devices and MSR 50 series routers can function as PE devices to access the networks in branches. More than one VPN can be built for different services so as to guarantee security between them.

The following figure is a typical network.


5-5

Figure 5-5 MPLS VPN network application

H3C NE series high-end and core routers are used as P devices in the headquarters. MSR 50 series routers are also used as PE devices to access the service networks of branches. With VPF technology, diverse services in branches are partitioned into different VPN networks through PE devices, guaranteeing the security and reliability of services.

MSR 20/30 series routers are used in branches to connect to MSR 50 series routers in the headquarters. Different services are separated through physical networks in branches. When there are many services in a physical network, the VRF feature of MSR 50 can realize logical separation of service networks.

You can use different ways to build tunnels for MPLS VPN services. Using MPLS TE tunnel to carry VPN services is of great benefits in many aspects. As a result, VPN services have superior security and reliable QoS guarantee. Additionally, carriers can customize MPLS TE tunnels with different features to meet VPN user requirements.

5.6 Network Application of Voice Services

The next generation of MSR series routers provides mainstream voice communication protocols like H.323 and SIP for a variety of voice services such as emergency call/help in power off/dial-in policy/fax/E-PHONE and a variety of voice interfaces such as FXS/FXO/VE1/VT1/E&M.

By leveraging an extensible structure, the next generation of MSR series routers allocates DSP resources consistently for higher DSP resource utilization, higher access density and local TDM switching. On the one hand, it provides qualified voice
