Reducing provisioned chassis power

Configuration

chassis {ambient-temperature 25C|40C|55C;

}

Goal

Reduce provisioned system power for most of the router deployments

Support more line cards

Version

MX2K:13.3R4

MX960, MX480, MX240: 13.3R6

Solution

By default the power is provisioned for the worst case (55C), instruct the system

to provision less

Support 11 x MPC4E or 11 x MPC5E in a chassis

Routing system upgrade scenario

Highlights

• Best in class edge platform

• Highest interface density in the industry

• Highest performance at small packet sizes

• Rich feature set8 x SFB

800 Gbps per slot

Routing system upgrade scenario

Highlights

• Protects investments into hardware (SFBs)

• Reduces software qualification efforts

• No JUNOS upgrade required, driver

installation is in service

Physical Interface

SR-IOV or VIRTIO

• Data packets are switched within vTRIO

• Multi-threaded SMP implementation

allows core elasticity

• Only control packets forwarded to

JUNOS

• Feature parity with JUNOS (CLI,

interface model, service configuration)

• NIC interfaces (eth0) are mapped to

JUNOS interfaces (ge-0/0/0)

Next Generation Port Extender

SatellitesAggregation Device

Implementation Details

Port Extender Advantages

• Management simplification: configuration, software

upgrades, performance management via aggregation

device

• Support for dual stack VLANs on satellite ports

• Plug and play operation

• 802.1br encapsulation between satellite and

aggregation device

• Extender device is modeled as a line card

81%100%

MPC6E

Solution

Reduce number of instructions per packet and number of memory

accesses for by eliminating some of the less used features (in hyper-

mode only)

Performance Optimized

• VPLS, L2VPN, L2circuit

• Layer 2 bridging and switching

• IPv4, IPv6 and MPLS forwarding

• L3VPN

Not Supported

• Virtual chassis

• DPC/DPCE Line Cards

• Subscriber Services

• Non Ethernet interfaces

• Ethernet Frames Padding

Problem Statement

Maintain line rate packet performance at smaller packet sizes (128

bytes and less) for applications such as peering / edge routing

MPC5E/6E Turbo Filters

Problem Statement

Maintain line rate packet performance at smaller packet sizes

(128 bytes and less) with filters enabled

Solution

Use ASIC filter acceleration available in MPC5E/MPC6E to

reduce number of microinstructions per filter and number of

external memory accesses
