TRES: traffic and reliability engineering server for MPLS

Abstract

Recently, Internet and intranet traffic has grown exponentially, increasing congestion and making operation of the backbone network difficult. Traffic engineering is needed for balancing the traffic load on the network, and it also helps in defining a policy for network operation. Reliability engineering is needed for protecting network connectivity in the even of a link or a node failure. In response to these demands, we have developed a server named TRES (traffic and reliability engineering server). TRES calculates and sets wide bandwidth paths while satisfying many policy constraints. It also provides path rerouting in the event of a link or a node failure.
