MPLS Switch Architecture Supporting Diffserv for High_speed Switching and QoS

摘要

In this paper, we propose the architecture of the MPLS switch supporting Differentiated Services in the MPLS-based network. The traffic conditioner consists of a classifier, a meter, and a marker. The VOQ-PHB module which combines input queue with each PHB queue is implemented to utilize the resources more efficiently, employing the Priority-iSLIP scheduling algorithm to support high-speed switching. The proposed MPLS switch architecture is modeled and synthesized by Very High Speed Integrated Circuits Hardware Description Language(VHDL), verified and then implemented by commercialized CAD tools to justify the validity of the proposed hardware architecture.
