  1. DRAGONDynamic Resource Allocation via GMPLS Optical Networks API Overview Jaroslav Flidr, Peter O’Neil, Chris Tracy Mid-Atlantic Crossroads

  2. DRAGON/IDC - API a simple interface to a very complex, distributed system • What it consists of • DRAGON Web Services and binary API • DRAGON UNI and CLI interfaces • IDC/OSCARS Web Services Interfaces • What it can do • schedule resources • enforce policies • authenticate • control Ethernet (VLANs) and TDM (SONET/SDH) resources • provision a Layer 2 path across different domains and heterogeneous network elements • How • Web Services interfaces • binary interfaces • UNI/CLI interfaces

  3. DRAGON as a Black Box AAA • reservation • full inter-domain capabilities • topology • provisioning • User • a researcher • another domain Web Services API (IDC/OSCARS) Vertical Vertical Wrapper / Translator API binary API Horizontal topology • provisioning • limited inter-domain capabilities UNI CLI port / VLAN / time slots port / VLAN / time slots

  4. API - Detail Abstraction Layer (Internet2 DCN, ESNet OSCARS extensions) Web Services API exported API Web 2.0 Layer (Inter-domain) IDCs internal API optional inter-domain interface DRAGON Layer (Inter-domain) NARBs UNI CLI i/f’s domain control interface DRAGON Layer Control Plane (Intra-domain) VLSRs hardware interface (network element drivers) control link (snmp, TL1, CLI) Network Infrastructure Layer 2 Ethernet, SONET/SDH Switches, ROADMs, etc.

  5. API types • Web Services (based on PerfSonar, NDL schemas) • external (provided by IDC/OSCARS) • reservation • topology exchange • provisioning • full inter-domain communication • internal (provided by TERCE) • topology exchange • provisioning • limited inter-domain communication • Binary (provided by NARB) • topology exchange • provisioning • limited inter-domain communication

  6. External Web Services API Example • Web Services interface • open for authenticated users and/or another domains • WSDL fragment: <?xml version="1.0" encoding="UTF-8"?> <wsdl:definitions name="OSCARS" . . . > <wsdl:portType name="OSCARS"> <wsdl:operation name="createReservation"> </wsdl:operation> <wsdl:operation name="cancelReservation"> </wsdl:operation> <wsdl:operation name="queryReservation"> </wsdl:operation> <wsdl:operation name="modifyReservation"> </wsdl:operation> <wsdl:operation name="listReservations"> </wsdl:operation> <wsdl:operation name="getNetworkTopology"> </wsdl:operation> <wsdl:operation name="initiateTopologyPull"> </wsdl:operation> <wsdl:operation name="createPath"> </wsdl:operation> <wsdl:operation name="refreshPath"> </wsdl:operation> <wsdl:operation name="teardownPath"> </wsdl:operation> <wsdl:operation name="forward"> </wsdl:operation> </wsdl:portType> . . . <wsdl:service name="OSCARS"> <wsdl:port name="OSCARS" binding="tns:OSCARSSOAP"> <soap:address location="https://oscars-dev.es.net:9090/axis2/services/OSCARS"/> </wsdl:port> </wsdl:service> </wsdl:definitions>
