Numerous studies based on complex measurement platforms have been carried out for over ten years now in order to discover the Internet topology on domain level. It turns out that this topology exhibits certain invariant properties such as a distribution of node degree. This distribution follows a power law. Moreover, the revealed topology is hierarchical. The hierarchy is caused by commercial contracts...
Localized Quality of Service (QoS) routing is a viable alternative to the QoS routing algorithms that use global network state information to make routing decisions. In localized QoS routing algorithms each source maintains a predetermined set of candidate paths for each destination and avoids the problems associated with the maintenance of global network state by using locally collected flow statistics...
This paper discusses and evaluates the behaviour o fa DS-TE algorithm (DiffSev aware MPLS traffic Engineering) called PEMS, and a dynamic multipath routing algorithm for load balancing (LBWDP), applied on a huge topology that correspond to real network. To clarify network topologies and routing algorithms that are suitable for MPLS traffic engineering, we evaluate them from the viewpoint of network...
