Patent ID: 7929434

Claim:
A method for setting limit values of an access control for limiting traffic transmission in a communication network, wherein the communication network comprises a plurality of pairs of marginal nodes at margins of the network, each pair associated with a set of possible paths comprising internal nodes and internal links leading through the communication network which run between each pair and through which the transmission occurs along a possible path without explicit path reservation, the method comprising: for each pair of marginal nodes in the communication network, (a) initializing the limit values to a predetermined initial low value such that substantially the same high blocking probabilities exist for all pairs of marginal nodes thereby avoiding an overload situation in the communication network; (b) iteratively increasing the limit values until an overload situation is identified at one of the internal links; (c) determining which of the pairs of marginal nodes contributed to the overload situation at the identified internal link by determining which of the pairs have possible paths that run through the identified link; (d) setting the limit value or the pairs of marginal nodes that contributed to the overload situation to a limit value of an immediately prior iteration; (e) repeating steps (b) through (d) until limit values are set for all pairs of marginal nodes as overload situations are identified at other internal links, thereby providing access control at the margins of the network by setting limit values for each pair of marginal nodes based on its respective contribution to overload situations occurring at internal links in the set of possible paths for that pair of marginal nodes.
