DSA-SCTP: An extension of SCTP to reduce web response time

SCTP multi-streaming provides an aggregation mechanism to multiplex logically separate message streams to the same association. While the current SCTP creates streams only at the initial association establishment phase and afterwards the streams are not allowed to modify. When transmitting web objects concurrently with multi-streaming, it causes unnecessary waiting, as a result of large objects occupying the streams while small ones having no streams allocated. In this paper, we proposed an extension to the standard SCTP to support dynamic stream addition during the communication. We implement Dynamic Stream Addition SCTP (DSA-SCTP) to the web application to reduce the response time of the web server. The performance evaluation of DSA-SCTP for the web is studied through ns-2. The results show that the proposed DSA-SCTP brings a remarkable improvement to the web server´s response time. The results also indicate that DSA-SCTP can be implemented to the similar applications as web to improve their performance.
