1 OESS AM, OESS STITCHING FLOWSPACE FIREWALL AL2S and GENI

2 OESS provides point-to-point and multipoint circuits across an OpenFlow substrate. Deployed on Internet2’s AL2S network. OESS AM provides a GENI interface to OESS circuit provisioning – Takes GENI AM API requests and translates them into OESS API requests Based on FOAM -- modified to support OESS API – Advertises available AL2S/OESS resources (endpoints, trunks) – Receives requests for AL2S/OESS circuit creation/removal, talks to AL2S OESS to make changes to network – ‘GENI-FOAM’ workgroup defines access policy for GENI users New for this GEC: Stitching support FOAM on AL2S

3 FOAM OESS AM extended to support stitching Stitching supported on any AL2S interface that has interdomain provisioning enabled – NOC ticket to enable port for interdomain – Port owner creates ACL(s) granting ‘GENI-FOAM’ workgroup access to a set of VLANs – AL2S AM will then automatically advertise this port in stitching advertisement – Current Limitations: 1 circuit per request. One remote link per port. AL2S Stitching
