Abstract
This invention provides a method and an apparatus for selecting path in a telecommunication network. In the invention, a control strategy parameter is generated based on a control strategy, and a network condition parameter is generated based on the condition of the network, a path cost for each of a plurality of candidate paths is calculated based on the control strategy parameter and the network condition parameter, then a path with the minimal path cost is selected from among the candidate paths.
Claims17
A method for path selection in a telecommunication network, comprising steps of:
- (a) defining a control strategy, and generating a control strategy parameter Util_weight based on the control strategy;
- (b) generating a network condition parameter based on the condition of the network;
- (c) calculating a path cost for each of a plurality of candidate paths based on said control strategy parameter, said network condition parameter, and network topology information;
- and
- (d) selecting a path with the minimal path cost from the candidate paths.
An apparatus for path selection in a telecommunication network, comprising:
- a control strategy parameter generating means for generating a control strategy parameter Util_weight based on a control strategy;
- a network condition parameter generating means for generating a network condition parameter based on the condition of the network;
- a path cost calculating means for calculating a path cost for each of a plurality of candidate paths based on said control strategy parameter, said network condition parameter and network topology information;
- and
- a path determining means for selecting a path with the minimal path cost from the candidate paths.
