LHCONE implementation in Asia

Challenge 1: keep delay (RTT) low Traffic between Asian countries must be routed within Asia (avoid transit to another continent or around the world)

Challenge 2: achieve full reachability Full reachability to all LHCONE sites is not achieved today KISTI CNAF MIT KREONET GARR TEIN Continental VRFs GEANT Internet2 X

Possible solutions Low delay: - Asian networks mesh their VRFs together, or - Asian VRFs get interconnected by a regional backbone Full reachability: - full mesh of VRFs, or - small VRFs get full transit from major VRFs

Missing items - TEIN VRF is not visible outside the GEANT domain (no transit through GEANT VRF) - KREONET VRF not peering with anything yet - ASGCnet VRF not connected to TEIN, KREONET, SINET yet. Planning to connect to APAN-JP - SINET VRF not connected to any Asian VRF

Agreed TODO list Implement missing peerings Start with peerings with TEIN ATCF future - discuss letter of agreement - ATCF #3 may be hosted by KISTI KR, right before the next LHCONE meeting in Asia - Involve more network operators

After the forum

Latest events Contacted KEK for SINET connection to TEIN - SINET will not give transit for the time being - Peerings will be activated in Singapore first, then Hong Kong - have to wait till June because the bandwidth in Singapore turned out to be just 1Gbps now TEIN will peer with Korea and Taiwan, after TEIN routers in Singapore and Hong Kong will be upgraded in July-August 2017

LHCONE in China - Two sites in China need LHCONE connectivity: IHEP (Beijing) and CCNU (Wuhan) - CERnet and CSTnet have been asked to implement LHCONE VRFs and peer with other VRFs in Beijing and Hong Kong (TEIN, ASGCnet)
