Abstract:
A method for detecting leaks in an Asynchronous Transfer Mode (ATM) network, the method comprising the steps of:first creating an entity interconnection map comprising mappings of port interconnections among a plurality of network nodes, wherein said plurality of network nodes comprises a plurality of network endpoints and at least one network switch; second creating an endpoint map comprising at least one endpoint mapping of at least one port to at least one virtual identifier for at least one of said network endpoints and a leak indicator for said at least one network endpoint indicating that said network endpoint is either a transmitting endpoint or a receiving endpoint; third creating a switch map comprising at least one switch mapping of at least one port and virtual identifier grouping to at least one other port and virtual identifier grouping for said at least one network switch; initializing a leak indicator for each of said endpoint mappings and said switch mappings to indicate a leak condition; traversing a virtual channel connection from each transmitting endpoint in said endpoint map to a corresponding receiving endpoint in said endpoint map via said switch map; and first setting each leak indicator for each endpoint mapping and switch mapping traversed along said virtual channel connection to indicate a no-leak condition.
