Abstract:
In a multiprotocol over ATM (MPOA) client, a method of dynamically adjusting aging time of a shortcut virtual circuit connection (VCC), comprising:detecting a packet flow between a source and a destination; establishing a shortcut VCC between the source and destination; defining a first VCC threshold level as 0 to (X/N)âˆ’1 unavailable VCCs, where X is the total number of VCCs that can be assigned by the MPOA client and N is the number of VCC threshold levels; defining a second VCC threshold level as X/N to ((2*X/N)âˆ’1 unavailable VCCS; defining an Nth VCC threshold level as (((Nâˆ’1)*X)/N to Xâˆ’1 unavailable VCCs; and adjusting an aging time for release of the shortcut VCC, the aging time being adjusted in response to a VCC threshold level chosen from one of the N defined VCC threshold levels.
