           Source Routing with Protocol-oblivious Forwarding 
              to Enable Efficient e-Health Data Transfer 
                        draft-zhu-srpof-ehdt-00

Abstract

   It has already been confirmed that software-defined networking (SDN)
   can make the networks more programmable, adaptive and application
   aware. However, due to the large-scale and geographically-distributed
   nature of wide-area networks (WAN), the scalability could become a
   critical issue if we incorporate SDN for WANs (i.e., realizing SD-
   WANs). In this paper, we design and implement a novel network system
   that can leverage source routing with the protocol-oblivious
   forwarding (POF) to facilitate efficient e-Health data transfers with
   low setup latency. We develop the POF-based source routing protocol
   to realize a pipeline based packet processing procedure, which can
   replace the table-lookup based approach in traditional SDN networks
   and make the forwarding plane more efficient. The proposed scheme is
   demonstrated experimentally, and the results verify that with it, the
   flow-tables installed in each core switches in a POF-controlled SD-
   WAN can be minimized and the path setup latency of traffic flows can
   be reduced significantly as well.

1  Introduction

   Nowadays, the fast development of data-intensive applications, such
   as e-Health, e-Science, e-commerce, etc, has brought us into the Big
   Data era. It is known that certain Big Data applications may generate
   huge volumes of data, which needs to be transferred over wide-area
   networks (WANs) for timely processing. For instance, in a
   telemedicine network, the health-monitoring devices worn by a large
   population of subscribers can contribute a fair amount of traffic for
   real-time processing . As the subscribers usually locate in a
