Optimizing Mobile Network Datagram Routing through Programmable Proxying

摘要

Public access to the Internet is nowadays even available in trains and airplanes. When such a network with several connected nodes changes its point of attachment to the Internet, it is called a mobile network. Unfortunately, mobile networks are not well supported by Mobile IP. In this paper, we describe Programmable Proxying, a dynamic approach for optimizing mobile network datagram routing. Transport layer connections originating from the mobile network will be handled by the programmable proxy, bypassing the home agents. In the case of a Mobile IP handoff, the proxy forwards ongoing connections to the new point of attachment.
