DOE/NGI Testbed Sites ESnetAbileneMREN

Planned DOE/NGI Testbed Capabilities Allocate bandwidth out of production ESnet service (30% of access link; Mbps per site) MREN sites determine bandwidth allocation Testbed will carry Best Effort + Premium traffic Resource control/allocation/scheduling Provide instrumentation assistance for applications to drive toward adaptive applications

DOE/NGI Testbed Implementation Site/edge routers will mark Premium Service flows Sites will ensure Premium Service to end systems ESnet & Abilene routers will police at ingress ESnet & Abilene will set PHB as needed Goal to ease manual configuration burden Goal persistent testbed infrastructure

8 sites require 28 p2p links L2 Infrastructure Full PVC mesh Bandwidth ?

L3 Infrastructure ANL Class C point-to-point subinterfaces using ip unnumbered use /32 subnet static routing between sites ANL /24

Software Globus GARA Cisco IOS 12.05T == 12.05XE –rsp-pv-mz –rsp-pv-mz This image will be officially released as 12.0(5)XE2 test tools need Web-based mechanisms for monitoring testbed status e.g., active reservations
