Using OSCARS Web-Based User Interface (WBUI) –SSL connection to server –Username and password login SOAP Messages –SSL connection to server –WSDL service description –Signed SOAP messages <wsdl:definitions name="OSCARS" targetNamespace=" xmlns:xsd=" xmlns:wsdl=" xmlns:soap=" xmlns:tns=" 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.

Source Sink MPLS labels are attached onto packets from Source and placed in separate queue to ensure guaranteed bandwidth. Regular production traffic queue. Interface queues SDN IP IP Link SDN Link RSVP, MPLS enabled on internal interfaces standard, best-effort queue high-priority queue 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. Label Switched Path SDN Link The Mechanisms Underlying OSCARS
