  1. Label Switched Path (LSP) Dynamical Provisioning Performance Metrics in Generalized MPLS Networks http://front.sjtu.edu.cn/~sunwq/draft-xie-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

  2. 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

  3. 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)

  4. 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

  5. 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

  6. 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

  7. 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
