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
