Description

In infocommunications networks the amount of free network resources varies in time significantly. Furthermore, after a network failure a large amount of backup paths are built up and later torn down. To achieve the highest possible network throughput and availability while keeping the loss of data low and guaranteeing fairness, the bandwidth (rate) of sources should be adjusted accordingly in an elastic way. After a complex network failure the path of the demand should be changed (re-routed) as well as its bandwidth likely decreased.
