QoS connection admitting method based on ipv6

Abstract

A ipv6-based QoS access method belongs to the network communication technology art. The invention adopts the existing route device as a route node of the communication network to achieve a QoS connection access mechanism by ipv6 protocol expansion message header based on the multi-layer and multi-domain network model. In the QoS connection access mechanism, only a border router is required to maintain a flow state, a core route tracks the outlet flow aggregation rate and simply control the local access. Due to a light signalling is adopted in the domain, the complexity of the end-end access control is greatly simplified, and the better expandability is provided. The mechanism can reduce the resource occupancy of the QoS connection without influenced by group lose and partly reserving failure. In addition, the mechanism can carry out self-correcting, namely, the overvaluation in the last period can be corrected in the next period. In conclusion, the access control algorithm can make the link utilization approach to the optimal.

Description

technical field [0001] The invention belongs to the technical field of network communication, relates to a point-to-point network communication technology, in particular to a QoS connection admission method suitable for large-scale networks. Background technique [0002] The Internet has developed vigorously since its appearance in the 1960s, and has grown at an alarming rate in recent years—the number of networked hosts doubles every year, and the number of web sites doubles every six months. At the same time, with the continuous cross-integration of computer, communication, and entertainment industries and the rapid development of multimedia technology, multimedia applications emerge in an endless stream on the Internet, and the amount of multimedia information is increasing day by day. With the vigorous development of new IPTV applications, not only the amount of data transmission on the Internet has been greatly increased, but also the nature of traffic has been changed....
