Title:
METHOD FOR DETECTING AN AVAILABLE/UNAVAILABLE STATE OF PACKET TRANSMISSION NETWORK
Document Type and Number:
WIPO Patent Application WO/2007/073644
Kind Code:
A1
Abstract:
A method for detecting an available/unavailable state of a packet transmission network includes the steps of: in the packet transmission network, detecting the severely errored second (SES) through the performance parameters of the packet transmission network, and detecting the available/unavailable time in the packet transmission network by reference to the SES. So the method of the packet transmission network entering or exiting the available/ unavailable state is realized, and the detection in the available time of the packet transmission network is realized. When the packet transmission network is available, the performance parameters of the packet transmission network is ensured to measure, and when the packet transmission network is unavailable, the measurement in the performance parameters of the packet transmission network is stopped. The method improves the packet transmission OAM mechanism, eliminates the defaults in the performance management of the packet transmission network.
