Label Switched Path (LSP) Dynamical Provisioning Performance Metrics in Generalized MPLS Networks ccamp-lsp-dppm-02.txt Weiqiang Sun and Guowu Xie, SJTU Guoying Zhang, CATR, MII Jianhua Gao, Huawei Rajiv Papneja, Isocore Bin Gu, IXIA Xueqing Wei, Fiberhome

Motivations Measuring LSP provisioning performance in the lab – Dynamic provisioning For interactive broadband multimedia services For Fast provisioning and recovery – Mapping of application requirements and the provisioning performance of the network – Maximizing common understanding of LSP provisioning performance between the service providers and network users/applications Measuring LSP provisioning performance in an operational network – Real-time control plane performance monitoring – Control plane maintenance and optimization

More Recent ASON deployment/tests in China China Telecom – 5 nodes, with GMPLS control plane – more nodes deployment expected China Netcom – 17 nodes in NE China China Unicom – 22 nodes, 9 with GMPLS control plane – GMPLS control plane for all 22 nodes expected ASON tests – CT, CNC, China Unicom (courtesy of G. Zhang, CATR)

Updates since last discussion Two more metrics – Multiple unidirectional LSP setup delay – Multiple bi-directional LSP setup delay – Motivation: setup multiple (potentially large number) LSPs during a short time interval For batch provisioning For failure recovery

Updates since last discussion (Cont.) Two test cases for obtaining samples of metrics – Performance for a “clean“ network state Reflects the inherent performance of a GMPLS control plane – Performance for a “loaded” network Reflects the performance of a medium or highly loaded GMPLS control plane

Open Issues UNI model or NNI model? – UNI model will results in simpler implementation – To implement the metrics online, NNI are also desirable LSP release delay – Two way signaling or three way signaling

Next steps Two teams work together to progress both items, in CCAMP and BMWG –draft-xie-ccamp-lsp-dppm-02.txt – draft-vapiwala-bmwg-rsvpte-convergence-motivation-00.txt Seek more input from the WGs Poll CCAMP’s interest in progressing the DPPM draft toward a working item Implement the draft in FPGA based hardware and/or Tester platform
