Dual HTTP

Dual HTTP

INTRODUCTION:

Today’s Web interactions are frequently short, which leads to an increasing number of responses carrying only control information and no data. Currently browser uses HTTP, which uses client-initiated TCP for all Web interactions. TCP is not always well suited for short interactions.
Client initiated TCP handicaps the deployment of interception caches in the network because of the possibility of disrupted connections when some client packets bypass the cache on their way to the server. This report explains a new transfer protocol for Web traffic, called Dual transport HTTP (DHTTP), which splits the web traffic between UDP and TCP channels. This protocol is proposed by Michael Rabinovich and Hua Wang. When choosing the TCP channel, it is the server who opens the connection back to the client. Among important aspects of DHTTP are

Adapting to bottleneck shifts between a server and the network and coping with the unreliable nature of UDP.

By using server-initiated TCP, DHTTP also eliminates the possibility of disrupted TCP connections in the presence of interception caches thereby allowing unrestricted caching within backbones.
