3 GMS Network LAN Reporting Portal

3.1 Underlying technology

The GMS reporting portal is built on InfoVista technology.

Your GMS LAN devices are polled and data is fed into a global VistaMart with an Oracle

Database. Your nominated users will be able to log directly into the portal and, depending ontheir configuration, will be presented with different views or packages of views. The VistaMart

system pre-packages the views and they are updated with new data as it comes in, so you cansee everything from near real-time to last poll cycle to historic information over months oryears.

Reports can also be scheduled by users and emailed.

3.2 Browser requirements

Internet Explorer IE7 or IE8 (a) or (b) or Firefox 3.5 are the supported browsers (if you have IE6or earlier you will need to upgrade).

Additionally, Sun Java Plug-ins Versions 1.5.0_16, 1.5.0_22, 1.6.0_17 or 1.6.0_20 (d) arerequired.

Under Internet Explorer and Sun Java Plug-in 1.6.0_10 or above, the following steps may beneeded for VistaPortal to work correctly:

1. Open the Java Control Panel.

Go to the Advanced tab.

2. Expand the Java Plug-in node.

3. Uncheck Enable the next-generation Java Plug-in (requires browser restart).

4. Close all Internet Explorer windows and restart the browser.

You will also need to ensure you add the site as a Trusted Source and Cookies must be

allowed for the site.

The Back navigation button used in client Web browsers allows you to display theprevious page delivered to the browser, regardless of whether the session is still valid on

the server. This means that a VistaPortal session may well have expired even though itis still possible to view the previous portal page using the Back button. In this case, nooperation will be allowed on the page, and it is no longer related to a session. Thereforewe recommend not using the Web browser navigation buttons when browsing the

reporting portal.

We recommend you log off and close your Web browser when you have finished with the

portal if you displayed sensitive information on a shared client. When you log on to the Web you create a session. The session you work in is associated

with your specific Web browser, which requires Cookies to function properly. When youlog out the session is destroyed.

If you create a new browser window (using File > New > Window in Internet Explorer

and Firefox), or create a new tab in Firefox or Internet Explorer 7 or above (using File >New Tab) from an existing session, the new browser or tab shares the parent session.This means that you cannot have different logins using the same Web browser. If youwant to use several different logins, you must create a new independent browser window

for each one.

3.3 No data available: causes and cures

When using the reporting portal you may occasionally see the No data available message and beunable to view a particular report. There are several potential causes.

Browser compatibility mode

Are you using Internet Explorer 8 with a recently updated version of JRE? You mayneed to set the compatibility mode in your browser. Please see IE8 No data availablefix to identify and resolve this issue.

Time navigationHave you used the time navigator to move to a reporting period for which data has yet tobe collected? Data is aggregated at the end of the collection period (e.g. daily data

becomes available every 24 hours).

If you attempt to view data which is not yet aggregated you will receive an error message.You can check if this is the problem by stepping back one collection period and seeing if thedata appears. If it does, you simply need to wait until the data aggregates for that period,

or use a more granular report to view the data (e.g. move from daily to hourly reports).

ProvisioningIf a new or recently reconfigured device/interface is not showing it may not yet have

been fully provisioned.

Your Client Manager can tell you how long a new device takes to be provisioned, but arough guide is around three days for new equipment to become visible in the reportingsystem once its on the network.

The Inventory Report allows you to view all devices and interfaces that are currentlybeing monitored. If you feel a device or interface ought to be visible but isnt, please callGen-i and we will investigate.

OutageFaults and outages can occur and they do affect reporting. If a monitored device isunable to reply to information requests for a sufficiently long period, then data otherthan availability (which will be at zero) will not be available for reporting. This situation

will be resolved once the device is back online and begins responding.

Planned maintenancePeriodic housekeeping does occur on the reporting platform and in rare cases this doesrequire downtime during which reporting may be unavailable for all or part of the

system, and for all or some users. Such outages will be avoided if possible, andcommunicated in a timely fashion where they are required.

3.4 IE8 No data available fix

Users with Internet Explorer 8 with recently updated versions of JRE may occasionally receive a

No data available message when viewing some reports.

The issue is due to the Web browser recognising that some elements of the portal page aredifferently compatible from previously. A bug of this sort is indicated by the following compatibilitybutton appearing within the browser address bar.

There are two ways to resolve this issue, as shown below.

Either:


8/43



1) Simply click on the compatibility button shown above.

Or:

2) Modify your browsers compatibility mode by taking the following steps:

i. Go to Tools > Compatibility View Settings.

ii. Set Compatibility mode globally or for particular sites.

Note: This exercise is needed only once. The next time you visit a site that

previously had this issue, IE8 will detect the site and automatically show the

pages in compatibility mode.

3.5 Polling frequency

InfoVista polls devices and interfaces every five minutes, and this data is then aggregated intohourly, daily and monthly reports.

3.6 Data retention periods

The following table shows the retention periods for the various data types:

Report Display rate Retained for

GMS Network Serviceonly

agreed service hours.

A site is deemed unavailable when no data can pass to or fromthat site during agreed service hours, unless the outage was aplanned outage, force majeure event or a failure arising on thecustomer side of the CLNE (Customer Located Network

Equipment).

Availability

calculations

Availability is calculated based on the percentage of time a

resource was available (responded to a poll or query). Thereporting system tracks the actual time between polls.

Average Average is calculated as a mean over the sample period (total

values/number of samples.

BER Business Edge Router. Business Edge Routers link the MPLS

Cloud to the client site connections in that area, providing arange of GWS network services to the connected sites and

managing the functions and performance of GWS siteconnections.

Buffer usage A devices buffer usage, as a percentage of its total capacity.

A buffer is generally a portion of memory that contains data thathas not yet been fully committed to its intended device. It isdesigned to take care of sudden short drops in the connectionspeed.

Class of Service (CoS) Class of Service is a method of grouping application traffic intotraffic classes and applying a particular Quality of Service (QoS)

to each traffic class.

The type of traffic class that you subscribe to, for example:

1.Real-time Best suited for applications that require low

delay, delay variation and packet loss, and are typically ofconstant rate, such as IP telephony (VOIP), point-to-pointvideo and video conferencing applications.

2.Interactive High Best suited for signalling and controlfunctions associated with real-time media.

3.Interactive Low Best suited for the clients network

management and control functions, and for applicationswhere a response is expected in near real-time, such as

Delivered traffic Packets that are effectively transmitted, as a percentage of thetotal submitted traffic.

Device Availability Percentage of availability of the device over the displayed period.A device is considered to be available when it responds to a Pingrequest; that is, it is fully operational. No response from the

device doesnt necessarily mean that it is unavailable, since theremay be a network transmission failure. In such a case, thedevice is in Unknown state.

Availability is one of the most important factors in the rating of a

service level. If a device is unavailable, its service level is zero.

Device Buffer

Utilisation

Measurement of the percentage of the total number of buffers

used during the display period compared to the maximumnumber of buffers allowed. Excessive percentage values in a

range produce buffer misses and/or buffer failures. (See also thememory usage.)

Device CPU

Utilisation

Average value for the percentage of CPU resources used during

each display period for the device.

Device Degraded

Mode

Percentage of saturation of the device over the displayed period.

Also referred to as degraded mode.

A monitored device is considered to be saturated when any oneof the following indicators (CPU, memory and buffer utilisations)exceeds a predefined threshold. Any time saturation is reported

the individual source factors should be checked carefully.

Device Memory

Utilisation

Percentage of memory used by the different functions of the

device. Used memory that is too high (above 60%) may result inbad performance.

Term Description

Interface A network card within a device. The component that processesthe network traffic.

Interface Indicators

Availability

Percentage of availability of the interface over the displayed

period; that is, percentage of time that the interface is ready for

transferring data to a destination device.


Degraded Mode

As a percentage, saturation (so-called Utilisation in degraded

mode) of the interface over the displayed period. Also referred toas utilisation in degraded mode. An interface is considered to besaturated when any one of the following indicators (Utilisation

IN/OUT, Error IN/OUT) exceeds a predefined threshold.


Error IN

This is the number of packets that were in error (dropped or

discarded) during reception (inbound traffic), expressed as apercentage of the total number of attempts. An excessive error

rate causes a high incidence of retransmission and consumescostly bandwidth. This is also an indication of the quality of the

transmission line.


Error OUT

This is the number of packets that were in error (dropped or

discarded) during emission (outbound traffic) expressed as apercentage of the total number of attempts. An excessive errorrate causes a high incidence of retransmission and consumescostly bandwidth. This is also an indication of the quality of the

transmission line.

Interface Indicators Utilisation IN

Utilisation IN measures the inbound traffic as a percentage of thetotal allocated bandwidth.

Utilisation is usually indicated against a predefined threshold.When a resource is used below that threshold, the interface is

capable of giving good service. Above the threshold, usersexperience impaired service levels.


Utilisation OUT

Utilization OUT measures the outbound traffic as a percentage of

the total allocated bandwidth.

Utilisation is usually indicated against a predefined threshold.When a resource is used below that threshold, the interface iscapable of giving good service. Above the threshold, the service

level drops and users feel the impact.

Inter-VLAN

forwarding

When traffic moves between VLANs on the LAN port of the GWS

Managed Router.

The main cause of Inter-VLAN traffic is VOIP signalling within asite. This consumes the forwarding capacity of the GWS-Managed router, and can lead to impaired service levels.

IP Internet Protocol.

IP packet loss The percentage of IP packets lost between the source anddestination CPE during the display period. A high packet loss

indicates transmission problems, and therefore a degradedservice.

IPSLA Internet Protocol Service Level Agreement: the agreed IP-related

performance targets.

IPSLA Reachability Addresses the transactions between two devices, where a source


41/43



Term Description

device is prompted to probe a destination device. The destinationdevice is considered reachable if it responds within a given timewhen addressed from the source device. This indicator does nottake into account cases where the source device cannot triggerthe transaction (e.g. if it is too busy), or cases where it does not

acknowledge the prompt.

Therefore, the indicator value is, as a percentage, the number of

times the destination device responds to requests compared tothe number of times the source device has triggered atransaction.

Reachability should not be confused with availability. A devicemay be available, that is to say up and running, but this does notmean that it can be reached through the network.

IPSLA Transaction

OK

Addresses the transactions between two devices, where a source

device is prompted to probe a destination device. As apercentage, the number of successful transactions compared to

the total number of times the source device is prompted to probethe destination device.

A transaction is successful each time the destination deviceresponds to the source device request before the timeout haselapsed.

IPV A node on the IPVPN.

Latency (IP packet

transfer delay)

The absolute time (in milliseconds) from the time the first bit of

an IP packet enters the client side of the source CPE to the time

the last bit of the packet exits from the client side of thedestination CPE.

Latency (one way) The overall site-to-site fixed delay for IP packet flows across the

GWS service.

42/43



Term Description

POI Point of Interconnect.

Polling All reporting in the Gen-i system is based on 5-minute polls at the

InfoVista Server level. The data in VistaMart on which mostVistaPortal reports are based may be hourly or longer intervals, bu

is always based on 5-minute data gathered from the devices. Thedata presented in VistaPortal is generally a mean or average of alldata polled, but based on the particular metric may be a max, minor other calculation as indicated in the name of the metric.

Currently, reports that display 5-minute polls are: QoS End-to-End

WAN Port Performance

Profiled QoS The SDR available to each traffic class is set by preconfigured

traffic profiles loaded into the CPE and BER. The traffic profiles arselected by the client from a predetermined list of traffic class SDR

combinations.

QoS Quality of Service. The ability of the GWS network to deliver a

defined level of performance to a traffic class. This may includetargets for maximum latency, jitter and packet loss.

QoS Dropped Traffic

(bps)

packets not transmitted), compared to the total traffic sent bythe Class-based QoS.

QoS Queue Depth In bits, provides the queue depth value of the Class-based QoS,

over the display period.

QoS QueuingDiscards

As a percentage, the number of bits which were dropped by theQoS queuing policy over the total number of bits submitted.

QoS Submitted

Traffic (bps)

Per second, sum quantity of the number of bytes that the Class-

based QoS has effectively transmitted, as opposed to thesubmitted Traffic value.

Response times Response time of the destination device to the request emitted

from the source device. The value is averaged for the displayperiod.

Term Description

SNMP Simple Network Management Protocol.

Speed The speed of the physical interface.

Static routing Routes across the GWS network are preconfigured in tables in

the CPE during implementation. Routing changes require therouting tables in every affected CPE and associated BER to bemanually updated by Gen-i operations staff, which means routechanges take more time to implement than with dynamicrouting.

Submitted traffic Per second, the sum quantity of the number of bytes submitted

to the Class-based QoS, regardless of the transmission successesand failures.
