  • Weiqiang Sun and Guowu Xie, SJTU
  • Guoying Zhang, CATR, MII
  • Jianhua Gao, Huawei

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

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 CCAMPs interest in progressing the DPPM
    draft toward a working item
  • Implement the draft in FPGA based hardware and/or
    Tester platform
