Bi-Directional Route Optimization in Mobile IP Over Wireless LAN

Tags:
local area networks (lan)

Overview This paper proposes to support symmetric bidirectional route optimization in mobile IPv4 considering ingress-filtering routers. The paper developed subnet-based direct tunneling techniques to improve the routing efficiency for mobile IP and a binding optimization technique to reduce the handoff latency for mobile nodes. An enhanced correspondent agent was introduced to collaborate with the home agent and the foreign agent to support these techniques. Utilizing a tunneling cache, datagrams sent from a mobile node can be directly tunneled to a correspondent agent, including Binding Update messages. The proposed approach can maximize the use of a bi-directional tunnel without abandoning the transparency to existing hosts.

VoIP primer: How it works - and what the jargon means

Any 'latency' - the delay in delivering the voice stream from the speaker to the listener - degrades the quality of the sound as does 'jitter' and 'packet loss'. But IP, of course, was not designed to provide a guaranteed quality of service (QoS...

Latency for instance cannot be allowed if a driver is relying on an impact warning before they take evasive manoeuvres. What's unique about the car-to-car initiative is that it relies on very little fixed infrastructure: instead of a car connecting...

Virtualisation: Architectual Considerations and other Evaluation Criteria

In the past several years, server virtualisation technology has moved quickly and firmly into the IT mainstream. Of the many approaches to system virtualisation available in the market today, VMware's hypervisor architecture has gained the greatest market acceptance. This paper examines the architectural issues, solution support, and enterprise readiness required when deploying such a virtualisation solution.
