7 new routers 4 new switches
Chicago MAN now connected to Level3 POP
2 x 10GE to ANL
2 x 10GE to FNAL
3 x 10GE to Starlight

ESnet Traffic Continues to Exceed 2 PetaBytes/Month
When A Few Large Data Sources/Sinks Dominate Traffic
it is Not Surprising that Overall Network Usage Follows the
Patterns of the Very Large Users - This Trend Will Reverse in the Next Few Weeks as the Next Round of LHC Data Challenges Kicks Off
ESnet Continues to be Highly Reliable; Even During the Transition
OSCARS Overview
OSCARS Status Update
ESnet Centric Deployment
Prototype layer 3 (IP) guaranteed bandwidth virtual circuit service deployed in ESnet (1Q05)
Prototype layer 2 (Ethernet VLAN) virtual circuit service deployed in ESnet (3Q07)
Inter-Domain Collaborative Efforts
Terapaths (BNL)
Inter-domain interoperability for layer 3 virtual circuits demonstrated (3Q06)
Inter-domain interoperability for layer 2 virtual circuits demonstrated at SC07 (4Q07)
LambdaStation (FNAL)

HOPI/DRAGON
Inter-domain exchange of control messages demonstrated (1Q07)
Integration of OSCARS and DRAGON has been successful (1Q07)
DICE
First draft of topology exchange schema has been formalized (in collaboration with NMWG) (2Q07), interoperability test demonstrated 3Q07
Initial implementation of reservation and signaling messages demonstrated at SC07 (4Q07)
UVA
Integration of Token based authorization in OSCARS under testing
Nortel

Network Measurement Update
ESnet
About 1/3 of the 10GE bandwidth test platforms & 1/2 of the latency test platforms for ESnet 4 have been deployed.
10GE test systems are being used extensively for acceptance testing and debugging
Structured & ad-hoc external testing capabilities have not been enabled yet.
Clocking issues at a couple POPS are not resolved.
Work is progressing on revamping the ESnet statistics collection, management & publication systems
ESxSNMP & TSDB & PerfSONAR Measurement Archive (MA)
PerfSONAR TS & OSCARS Topology DB
NetInfo being restructured to be PerfSONAR based
LHC and PerfSONAR
PerfSONAR based network measurement solutions for the Tier 1/Tier 2 community are nearing completion.
A proposal from DANTE to deploy a perfSONAR based network measurement service across the LHCOPN at all Tier1 sites is being evaluated by the Tier 1 centers
