Abstract: A system and a method of selecting gateways using stored metrics associated with each route out of the domain and with each destination is presented. The metrics represent some measure to be minimized by the routing system, such as cost or delay. The route is selected quasi-deterministically. A first selection is made deterministically based on the stored metrics in order to attempt to use the optimum path. If a connection can not be established through the deterministically selected gateway, an alternate gateway is selected randomly from among the remaining gateways capable of reaching the destination at a reasonable cost.

Abstract: In a methodology for route selection for path balancing in a connection-oriented packet switching network, a comparison is made of the measures of utilizations of a network resource by at least two links of a link group in the network, and at least one link is identified as a candidate for carrying traffic path based on the comparison. Network traffic path on the link is then moved to the candidate link to reduce variation in the utilization of the network resource by each of the links.
