Effect of Vertical Handovers on Performance of TCP-Friendly Rate Control

Overview This paper evaluates performance of TFRC during handovers between GPRS, WLAN, and UMTS. It measures behavior of TFRC and TCP flows in a testbed implementing vertical handovers using Mobile IP. To verify testbed measurements and to study the effect of changes in path characteristics, it uses an ideal handover model in the ns-2 simulator. Essentially, an ideal handover is represented by a step change in the bottleneck link bandwidth, latency, and buffer size, as if a smooth handover with packet forwarding were implemented.

The Ovum View: Mobility - still reasons to be cheerful

GPRS has had a slower start than planned, with the now-traditional late arrival of handsets, but also a distinct absence of compelling applications - and some implementations that are not up to scratch.

MPLS: The icing on the networking cake?

Iain Stevenson, networking analyst at Ovum, put it like this: "MPLS is a mechanism for labelling traffic flows to define a path through a complex network. Traditionally, a packet of data sent over an IP network goes straight from the original point...

What's the fuss about... network infrastructure?

It has WEP and can fall over to a GPRS environment if you have Mobile IP underpinning it. Look at least-cost routing, packet tunnelling, edge-of-network technologies - see how they can provide business benefits when applied to your network.

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.
