  1. OSCARS Overview OSCARS Guaranteed Bandwidth Virtual Circuit Services • Path Computation • Topology • Reachability • Contraints • Scheduling • AAA • Availability • Provisioning • Signalling • Security • Resiliency/Redundancy

  2. 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 <?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions name="OSCARS" targetNamespace="http://oscars.es.net/OSCARS" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap12/" xmlns:tns="http://oscars.es.net/OSCARS"> <wsdl:documentation> 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.

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

  6. ESnet Virtual Circuit Service Roadmap Initial production (L2-L3) service Full production service Today 2008 2009 2010 • Dynamic virtual circuit services for Layer 1 (TBD) connections (using GMPLS) • Dynamic virtual circuit services for Layer 2 (Ethernet VLAN) connections (using MPLS) • Dynamic virtual circuit services for Layer 3 (IP) connections (using MPLS)
