  1. Upgrades to Network APM Meeting, Barcelona (Spain), 3-4 February 2003 Robert Walton Network Engineer DANTE DANCERT security policy - Robert Walton

  2. New and Upgraded Access Circuits • Circuit was brought into service on 4th December 2002 • Although terminated on a STM-1 port was initially a 34Mb IP tunnel through a third party provider to ULAKBIM • The access circuit then was upgraded to a pure STM-1 connection via a satellite link on the 23rd January 2003. ULAKBIM AP • Circuit was brought into service on 3rd January 2003 • The circuit results in a change of provider from KDDI to NTT who appear to be managing the SINET/NII network. • The link capacity (STM-1) is the same as its predecessor but sees a move away from ATM. This was the last ATM circuit connected to the network. SINET AP DANCERT security policy - Robert Walton

  3. New and Upgraded Access Circuits • The circuits was brought into service on 23rd January 2003 • Both circuits were upgrade in line with the increased capacity to the Irish PoP (dual 2.5G circuits) • The increased bandwidth was from dual STM-1 to dual 2.5G capacities. HEAnet AP Primary and Back-up SANET AP • The circuits was upgraded on the 9th December 2002 • The increased access was from 100Mbps to 200Mbps by way of rate limiting on the GEANT GE interface. • The upgrade was accommodated by a move from FE to GE DANCERT security policy - Robert Walton

  4. Upgraded Circuits • The final circuit of the Greek migration from 4 x STM-1 to 2 x STM-4 (the other being UK-GR) • The increased capacity was from dual STM-1 to STM-4 • The circuit was brought into production on the 4th October 2002. DE - GR • The circuit was upgraded from STM-1 to STM-16 allowing HEAnet gigabit capacity to GEANT. • The circuits was terminated on the new Juniper M40 which had been installed to accommodate the upgrade. A migration then occurred. • IE - DE is provided by Global Crossing and was brought into production on the 20th December 2002 IE - DE DANCERT security policy - Robert Walton

  5. Upgraded Circuits • The circuit was upgraded from STM-1 to STM-16 allowing HEAnet gigabit capacity to GEANT. • The circuits was terminated on the new Juniper M40 which had been installed to accommodate the upgrade. A migration then occurred. • IE - UK is provided by Cable and Wireless and was brought into production on the 22nd January 2003 IE - UK DANCERT security policy - Robert Walton

  6. DWS Upgrades Two NREN’s had their DWS subscriptions upgraded, both in December 2002. Those were, Grnet - Upgraded from 155Mbps to 310Mbps Roedunet - Upgraded from 35Mbps to 70Mbps. Grnet are also intending to first increase their DWS subscription to 465Mbps and then ultimately to 622Mbps. DANCERT security policy - Robert Walton

  7. Proposed Network Upgrades • Access port to Russian Research network will be connected to GEANT at the Swedish PoP provided by TELIA. • Roedunet access circuit will be upgraded from STM-1 to STM-4 • HU-SI GEANT circuit will be upgraded from STM-1 to STM-4 DANCERT security policy - Robert Walton

  8. QoS config The QoS configuration has completed on most of the GEANT routers allowing Premium IP, Best Effort and Less than Best Effort class of services. These routers are represented as green on the following map. The routers coloured yellow are those that have been reused from TEN-155, these have old FPC’s that do not allow for the full functionality of QoS. As such BE is not ideally protected by LBE and the bandwidth is effectively shared. The red routers are the Cicsco 7k’s, these routers are not powerful enough to provide QoS functionality.
