Abstract

Although the progress in the optical technologies will put an unheard-of transmission capacity at the users disposal in the near future, to fully take advantage of that bandwidth the nodes in the network have to be able to provide QoS and Value Adding Services (VAS) to those same users at wire-speed. One of the most critical aspects, which is being researched inside the high-speed routing activities within the GIGA-RING project (itself part of the german initiative KomNet), is packet classification in a hybrid routing node. In this paper, we present a novel approach that overcomes the scalability issues of this question by means of a hierarchy of filter databases based on the semantics of the rules. We also demonstrate how our model helps the nodes support QoS and VAS with an example of outsourcing Virtual Private Network (VPN) services.
