user-perceived qos mechanism under sctp/ipv6
Internet has evolved greatly from its original incarnation, such as two new technologies have arisen, SCTP and IPv6 corresponding to TCP and IPv4. Because of the advantages, the new architecture SCTP/IPv6 will replace the TCP/IP architecture very probably in the future. On the other hand, considering that the Internet was designed to meet the different needs of users, the evaluative criteria of a new network design has not changed and it must reduce to the following question: how happy does this design make the users? This paper presents an efficient end-to-end user-perceived QoS mechanism based on SCTP priority multi-stream and IPv6 multi-path, which could provide different end-to-end service quality for different users. Firstly, we present the design principle of new QoS mechanism under SCTP/IPv6; then based on optimization theory and queuing theory, we build two models for new mechanism; finally, based on model analysis we prove the efficiency of the new mechanism.
