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

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
