3. IP Services (SLA J3)3.1 IP Service (SLA J3.1) 3.1 IP Service (SLA J3.1)This reporting period has seen a total of 33 new or enhanced customer connections completed and brought into use:
For information regarding current upgrades or connections, please contact JANET Service Desk at: connect@ja.net. A list of all primary sites connected to JANET may be found at: http://www.ja.net/janet-sites/. (b) FEEngland Wales (c) Core NetworkA major fault occurred on 30 January on the backbone core router at Reading C-PoP that caused IP traffic flowing through that router to be black-holed by one of its cards. However, to the backbone routers everything looked normal: internal routing protocol traffic between the routers was not affected and hence they saw no reason to re-route production traffic passing through the Reading router. Consequently, during this period, regional network traffic flowing on the west side of the backbone was severely disrupted. Once the location of the problem was pin-pointed, senior engineers collected as much evidence and diagnostic information as was available before recovering the situation. This information is now with the router supplier and the manufacturerm with whom we are working to identify the exact cause of the fault. Elsewhere the core network runs without interruption. Network engineering work for re-pointing the A-end of two of Network North West Regional Network's backbone access links was completed successfully at the end of January. (d) External Network Access Provision and Transmission(i) Access to the European Research NetworkJANET access to European NRENs is via a 10Gbit/s connection to GÉANT from the Telecity R-PoP with a 10Gbit/s backup connection from the Telehouse® R-PoP. Peak traffic on the connection is normally under 3Gbit/s but in the middle of November it peaked at 5Gbit/s.
(ii) Access to the Global InternetJANET access to the global Internet is via two global transit providers - TATA Communications and TeliaSonera. Each company provides four 10Gbit/s connection to two JANET PoPs at Telehouse® and Telecity in London. Aggregated peak traffic reached 13Gbit/s in January 2010.
(iii) Access to the UK's Internet ExchangesJANET access to the LINX (London Internet Exchange) is via four 10Gbit/s connections from the Telehouse® and Telecity PoP locations. Aggregated public peering traffic peaked at 14 Gbit/s in January 2010.
(iv) Access to CERNETAll traffic to CERNET is now via GÉANT. The service was stable during the reporting period. (v) Access to North American Research InternetsServices are provided via GÉANT and have been stable throughout the reporting period. (vi) Peer Networking Agreement Administration
3.2 Fault Reporting (SLA J3.2)The JANET Service Desk handles the fault reporting function. Fault reports should now be made to service@ja.net. 3.3 Management of Maintenance Activities (SLA J3.3)During the reporting period there were a total of 11 planned maintenance sessions, with a moratorium on any major service affecting work taking place during the period from 18 December to 4 January. Major activities that took place included:
3.4 Network Status Information (SLA J3.4)The new Netsight system is now the official JANET Netsight system with all local/regional networks transitioned, with the exception of PSBA (Wales). The transition project is therefore officially complete. The new system is known simply as Netsight and is operational under the remit of the JANET(UK) Service Analysis Group. 3.5 Time Reference Service (SLA J3.5) [more information]Seven more sites registered to use the JANET NTP service during the reporting period. There are a total of 259 sites using it. Overall, it is a stable and well-used service.
