Method and apparatus for supporting call admission control using graph assembly and fate-share identifiers

摘要

In one embodiment, a method includes obtaining a potential bandwidth deduction at a call agent, the call agent being associated with an intercluster call admission control (CAC) arrangement in which bandwidth is shared, the potential bandwidth deduction being associated with a session. The method also includes determining whether the potential bandwidth deduction is a duplicate bandwidth deduction, deducting the potential bandwidth deduction from a bandwidth bucket when it is determined that the potential bandwidth deduction is not the duplicate bandwidth deduction, and ignoring the potential bandwidth deduction when it is determined that the potential bandwidth deduction is the duplicate bandwidth deduction.

1. A method comprising:
obtaining a potential bandwidth deduction on a communications interface at a call agent, wherein the call agent is a Unified Communications Manager (UCM), and wherein the call agent includes a processor and the communications interface enables the call agent to communicate on a network, the call agent being associated with an intercluster call admission control (CAC) arrangement in which bandwidth is shared between the call agent and other call agents on the network, the potential bandwidth deduction being associated with a session; determining whether the potential bandwidth deduction is a duplicate bandwidth deduction, wherein determining whether the potential bandwidth deduction is the duplicate bandwidth deduction includes identifying an originator of the session, identifying a terminator of the session, determining when the originator and the terminator are both Internet Protocol (IP) trunks, and determining whether the IP trunks are configured for call signaling information to pass through when it is determined that the originator and the terminator are both IP trunks, wherein when it is determined that the IP trunks are configured for the call signaling information to pass through, the potential bandwidth deduction is determined to be the duplicate bandwidth deduction, and wherein when it is determined that the potential bandwidth deduction is the duplicate bandwidth deduction, the indication is that the potential bandwidth deduction has already been accounted for; deducting the potential bandwidth deduction from a bandwidth bucket when it is determined that the potential bandwidth deduction is not the duplicate bandwidth deduction, wherein the bandwidth bucket is locally associated with the call agent; and ignoring the potential bandwidth deduction when it is determined that the potential bandwidth deduction is the duplicate bandwidth deduction, wherein the potential bandwidth deduction is determined not to be the duplicate bandwidth deduction when it is determined that the originator and the terminator are not both the IP trunks.
