Abstract:
1. A method for load balancing data connections in a cluster of traffic nodes over at least first and second time periods, the method comprising the steps of: determining a number of data connections established by a first traffic node of the cluster in a first time period; computing a load capacity of the first traffic node by multiplying the number of established data connections with the duration of the first time period; computing a maximum load capacity for the cluster by multiplying a maximum number of data connections available for the cluster with the duration of the first time period; receiving a load capacity of a second traffic node from a second traffic node of the cluster; comparing a sum of the load capacity of the first traffic node and the load capacity of the second traffic node to the maximum load capacity for the cluster; if the sum is greater than the maximum load capacity for the cluster, waiting for a number of data connections to be closed by themselves in the second time period; if the sum is lower than the maximum load capacity for the cluster, accepting a number of data connections in the second time period.
