1/83.4.3.1 Connection oriented
When dealing with a traditional HTTP 1.0 request, a TCP/IP connection is opened for the request and closed when the request is finished. Thus, HTTP is connectionless. The retrieval of every inline image is a separate HTTP request. Initially, a TCP connection does not use the full bandwidth available because of behavior referred to as slow start; to avoid a network overload only few a packets are sent during the start of the connection. Only after some time is the full bandwidth used. Since HTTP requests are quite short in general, the full bandwidth is rarely used. The HTTP/1.1 proposal contains persistent connections, and state-of-the- art WWW clients and WWW servers do use them. There are still problems with proxy servers which do not establish the connection properly.
HG-CSP has always been connection oriented, which has too main advantages. First, the full bandwidth is used, and second, since the client is always connected to the server, the server can send messages to the client without any request of from the client. This allows synchronous communication which is very important for collaboration.
