This is WSDL for the OSCARS public reservation interface. These

messages must be signed using the following WS-secuirty

standards. The message is time stamped and includes the X.509

certificate of the signing entity. The timestamp, certificate

and message body are all signed. DRAFT V1.0 Nov 2006

LSP between ESnet border routers is determined using topology information from OSPF-TE. Path of LSP is explicitly directed to take SDN network where possible.

On the SDN Ethernet switches all traffic is MPLS switched (layer 2.5).

Layer 3 VC Service: Packets matching reservation profile IP flow-spec are filtered out (i.e. policy based routing), policed to reserved bandwidth, and injected into an LSP.Layer 2 VC Service:Packets matching reservation profile VLAN ID are filtered out (i.e. L2VPN), policed to reserved bandwidth, and injected into an LSP.

ESnet Virtual Circuit Service Roadmap

• Dynamic virtual circuit services for Layer 3 (IP) connections (using MPLS)

• Dynamic virtual circuit services for Layer 2 (Ethernet VLAN) connections (using MPLS)

• Dynamic virtual circuit services for Layer 1 (TBD) connections (using GMPLS)
