motivations
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
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
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
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
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
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
