An Enhanced Handoff Mechanism for Cellular IP

Tags:
tcp - ip

Overview Handoff is one of the most important factors that may degrade the performance of TCP connections in wireless data networks. This paper presents a lossless and duplication free handoff scheme called LPM (Last Packet Marking) for improving Cellular IP semisoft handoff. LPM signals the safe handoff cue by sending a specially marked packet to mobile hosts. With this control packet, MH can adapt to network dynamics simply and efficiently. The performance study shows that LPM achieves lossless packet delivery without duplication and increases TCP throughput significantly.

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.
