1 TeraPaths and dynamic circuits Strong interest to expand testbed to sites connected to Internet2 (especially US ATLAS T2 sites) Plans started in early 2007 Collaboration workshop at BNL in May 2007 Series of modifications and additions to TeraPaths code to request (through OSCARS) and utilize dynamic circuits Expansion of testbed to BU through NoX and second (L2) connection to UMich through Merit/MiLR SC’07 demo in November 2007

2 Using a circuit Dynamic circuit appears as VLAN connecting end site border routers with single hop Cannot use flow ID data directly Flow must be directed to the proper VLAN WAN admission performed within end site LAN Select VLAN with Policy Based Routing (PBR) at both ends Route can be selected on a per-flow basis WAN switch border router

3 End site VLAN setup for L2 TeraPaths-controlled “virtual border” router (directs flows w/PBR) e.g.,1 to X, 2 to Y WAN Site’s Border Router trunked VLAN pass-thru 50 VLAN ids (3550-3599) 3550 X Y 3599 interfaces trust DSCP TeraPaths-controlled host router #X #Y DSCP-friendly LAN host 1host nhost 2... 1 to X 2 to Y can be the same device Regional Provider’s Router

4 Interoperating with WAN Services TeraPaths “proxy” servers Implement interface required by TeraPaths core Hide WAN service differences Clients to WAN web services (currently OSCARS / DRAGON) Close cooperation with ESnet and I2 development teams Submit reservations for MPLS tunnels or dynamic circuits Handle security requirements Handle errors
