Paper Abstract

This paper presents a novel Policy-based Flow Switching (PFS) method used in packet networks. Unlike traditional per-packet forwarding method, PFS only performs extensive processing on the first packet of a flow, associates this flow with a policy and applies the result of this processing on subsequent packets in the flow. Thus, PFS has the capability of flexible services offering and can significantly improve data forwarding rate, without introducing any complex signals. In this paper, we present the architecture overview of PFS and introduce some of the implementation issues. Besides, this paper also demonstrates how PFS is implemented on a 128Gbps NPU-based high-end router.
