Work in Progress• Example list of Key Performance Indicators (KPIs)
assembled.• Analysis of JANET SLA document• New monitoring tools under trial.• Initial rough availability stats compiled for Q1 2005.• First run of draft client questions compiled.• Other resources such as Sonas report and OS1 work
identified.
![Page 13: Comparison of NREN Service Level Agreements](https://reader036.fdocuments.in/reader036/viewer/2022082517/56812c4a550346895d90ce32/html5/thumbnails/13.jpg)
Initial KPIs• Client Accessibility, both v4 and v6.• Outbound access to Géant2 & General Internet.• Service availability• Mean Time Between Failures (MTBF).• RTTs to Clients and other sites.• Throughput on connections.• NOC response times
– Per service type– Per request type

Initial Questions
• Questions for clients broken into ‘hard’ & ‘soft’.• Start with softer questions to gauge
expectations before asking harder, direct and enumerable questions.
• E.g. Soft – “Are you happy with your current levels of service with HEAnet?”
• Hard – “In scenario X, what availability would you expect from HEAnet?”

Still to do
• Expand comparison with other NRENs
• Refine taxonomy for service types– Allow for future flexibility within limits
• Link specific benchmarks and metrics to service types
• Define operational policies
