Abstract

The path computation element architecture has been proposed to separate forwarding and routing functionality in small-scale connection-oriented networks, such as MPLS, GMPLS, and ASON. If routing is performed by dedicated units, more sophisticated methods, such as multi-constraint QoS routing, may be implemented than currently widespread practices (i.e. OSPF, IS-IS, BGP, etc.). In this paper, we present a performance analysis of several distributed multi-domain QoS routing algorithms that may be implemented on the PCE platform.
