摘要:
A method to assist in deciding whether or not an ATM PNNI network link is able to sustain a new connection is described. The method comprises, if the link is not within an LCN exhaustion state and the new connection requests more bandwidth than is advertised as being available upon the link for the new connection's service category, regarding the bandwidth available for the new connection as a sum. The sum comprises addition of: 1) the advertised available bandwidth and 2) the total bandwidth reserved on the link for connections having lower priority than the new connection enhanced by over-subscription for the service category.
摘要:
A method and system thereof for checking connectivity between endpoints in a network are described. A message is sent from an originating endpoint to a terminating endpoint. The message directs the terminating endpoint to enable detection of continuity check cells used for checking connectivity between the originating endpoint and the terminating endpoint. The terminating endpoint is programmed to suppress generation of continuity check cells. Continuity check cells are sent from the originating endpoint to the terminating endpoint. The originating endpoint is programmed to refrain from acting in response to an absence of continuity check cells from the terminating endpoint.
摘要:
A method and system for connection routing based on link utilization. A link utilization limit is accessed at a node of a network. The link utilization limit is compared to a utilization of a link coupled to the node. If the utilization of the link is greater than the link utilization limit, then the link is excluded from a virtual circuit.
