A distributed scheme for inter-domain routing optimization
(2007) 6th International Workshop on the Design of Reliable Commuication Networks DRCN 2007- Abstract
- The goal of the paper is to present a decomposed approach to optimization of inter-domain routing in IP networks. A problem of maximizing the total amount of traffic carried in an inter-domain network is formulated as a linear programme. Using Lagrangean relaxation the problem is decomposed with respect to individual domains. A resolution method based on subgradient optimization combined with recovering of a near optimal primal solution is discussed. Effectiveness of the method for the case of synchronized local intra-domain computations is tested using two different subgradient optimization algorithms: a divergent series algorithm and a proximal bundle algorithm. The issue of implementing such a method in a distributed networkwide process... (More)

Two schemes for such decomposed optimization involving only partial synchronization of local intra-domain computations are discussed. (Less)
