BGP-4 is the routing protocol which holds the Internet together. Additionally and in the absence of a better solution, it is being used for traffic engineering purposes. In the absence of standardised procedures, each autonomous system in the Internet implements traffic engineering based on non-collaborative goals and using trial and error techniques. This paper analyses trial and error traffic engineering...
One of the tasks of network management is to dimension the capacity of access and backbone links. Rules of thumb can be used, but they lack rigor and precision, as they fail to reliably predict whether the quality, as agreed on in the service level agreement, is actually provided. To make better predictions, a more sophisticated mathematical setup is needed. The major contribution of this article...
Sometimes the backbone network of Internet experiences congestion because traffic is not distributed rationally. This fact may lead network resources utilized inefficiently. The main idea for load balancing is to alter the route for some traffic. But current approaches with this idea often get such a long route that decrease the quality of service. This paper presents a new flow routing adjustment...
