N3 Monitoring and Capacity Reporting

N3 is managed on behalf of the NHS by N3SP included in this management service is the active monitoring of the network. N3SP uses automated systems to monitor the network infrastructure to ensure it is operating correctly - a suite of tools that constantly monitor all N3 devices. If any device, or group of devices, has a fault the N3 monitoring systems will show an alarm. The alarms help N3SP diagnose problems quicker and more effectively by:

  • providing information about where the faults is
  • provide a wider picture of the ‘health' of the network

Often these systems allow N3 to identify problems and fix them before the end user is aware and has reported a fault.

N3SP also provides historical usage (‘capacity') reporting for all live end users who are directly connected to N3*. Data is collected regularly from N3 routers at end-user sites. HSCR (High Speed Customer Reporting) then aggregates the data and produces data tables and graphs showing usage, typically as percentage of the maximum possible data rate a service can operate at.

* Where an end-user is part of a COIN and connects to N3 via a COIN gateway, monitoring capability is dependent on the hardware in use for the COIN.

N3 Service Portal

Service reporting within the N3 Service Portal gives customers a detailed view of the performance of the service and network elements of their N3 connections.

The reports are generated by a BT system called High Speed Customer Reports (HSCR) which has been tailored for N3 requirements. HSCR generates textual and graphical performance reports based upon N3 network router information.

There are two types of report Dashboard and Customer Reports. Reports are generated based on profiles defined by groups of network devices (routers).

The N3 Service Portal can also be used to track the progress and resolution of incidents. The N3 Helpdesk incident tracking system regularly updates the service portal with this information.

HSCR and Customer Reporting

HSCR produces automatic standard format weekly and monthly reports in Microsoft Word or PDF format. HSCR has a self-service web interface where users can:

  • download historic PDF reports
  • set-up and run HSCR near real-time and historical usage reporting

This report shows usage statistics for one N3 site. The site here has a 2Mb/s serial connection as primary and an ADSL line as secondary connection (shown here as ATM0/0).

Here is an example of a on-demand graphical report. It shows the bandwidth used as a percentage of maximum capacity/data rate.

 

HSCR report

 

Since QoS was introduced onto N3, HSCR can also provide statistics on each QoS class against the contracted bandwidth for that class (see N3 Network Overview for further explanation of QoS ). Because QoS guarantees each class of traffic a minimum bandwidth, whilst allowing other traffic to burst into any unused bandwidth, QoS reports showing > 100% of the contracted bandwidth in use is normal.
