Abstract
The invention provides a system and method of a selecting an egress connection from egress connections at a node for a call being established in a network along a path being associated with the node. Each connection has sufficient bandwidth to carry the call and terminates at a same destination point in said path. The system and method comprise utilizing at least a bandwidth load balance value for each connection in a set of the connections to select the egress connection from the set. An administrative factor score may be used to further define members of the set.
Claims20
A method of a selecting an egress connection from a plurality of egress connections at a node for a call being established in a network along a path being associated with the node, each connection of said plurality of egress connections having sufficient bandwidth to carry said call and terminating at a same destination point in said path, said method comprising utilizing at least a bandwidth load balance value for each connection in a set of said plurality of egress connections to select said egress connection from said set.
A system for selecting an egress connection from a plurality of egress connections at a node in a network for a call being established in said network along a path being associated with said node, each connection of said plurality of egress connections having sufficient bandwidth to carry said call, said system comprising:
- a connection selection module adapted to select one connection from a set of said plurality of egress connections to carry said call by determining a bandwidth load balance value for each connection in said set of connections and selecting said one connection by comparing bandwidth load balance values of connections in said set of connections.
A method of selecting a trunk group for routing a call in a connection-based network, said method comprising the steps of:
- (a) identifying a set of trunk groups that are capable of meeting requirements of said call, each trunk group of said set having a same destination node;
- (b) accessing a previously determined administrative factor for each trunk group of said set;
- (c) if only one trunk group of said set has the lowest administrative factor, selecting a trunk group with the lowest administrative factor for routing said call;
- and
- (d) if a plurality of trunk groups of said set has the lowest administrative factor, calculating a bandwidth parameter for each trunk group of said plurality, and
- selecting a particular trunk group from said plurality for routing said call utilizing said bandwidth parameter.
