  • Network assessment and short-term planning procedure
    Patent number: 8451736
    Abstract: A method for relieving network node congestion includes determining a moving average of an aggregated load on a network node that routes network traffic using historical data for a period of time for a portion of a communication network that includes the network node. Demand on the network node is projected based on the moving average. A current level of congestion on the network node is determined. A level of congestion on the network node is projected based on the projected demand and the current level of congestion. Available capacity of other network nodes in the portion of the communication network is estimated. A determination is made whether the projected level of congestion can be relieved using the estimated available capacity of the other network nodes. The communication network is reconfigured to relieve the projected level of congestion when the projected level of congestion can be relieved.

  • Network assessment and short-term planning procedure
    Publication number: 20070147264
    Abstract: A method for predicting node blockage in a telecommunications network includes determining an aggregated load on a network node and determining a current level of blockage on the node. A demand on the node is projected based on the determined aggregated load. A level of blockage of the node is then projected based on the projected demand and the determined current level of blockage.
