Abstract

The invention relates to a QoS (Quality of Service) broadcast method for an Overlay network based on a genetic algorithm. The method specifically comprises the following steps of determining a source node and a target node of multicast routing at an IP (Internet Protocol) layer; converting the multicast routing at the IP layer to broadcast routing at an application layer through the Overlay network; constructing a QoS target function meeting the multimedia application requirement; and utilizing the genetic algorithm to construct an optimal broadcast tree for the target function, and transmitting data from the source node along the broadcast tree. The method can be realized on the Internet, the network resources can be greatly saved, the cost is reduced, and the expansibility is strong.

Description

technical field [0001] The invention relates to the field of communication computing, in particular to a genetic algorithm-based Overlay network QoS broadcasting method. Background technique [0002] With the continuous expansion of network scale and the popularization of multimedia applications, users put forward higher and higher requirements for Internet service quality, mainly including three aspects: one is to ensure bandwidth, the other is to reduce delay, and the third is transmission cost. In order to effectively utilize network resources and reduce transmission costs, Internet service providers often use multicast to transmit the same data to multiple users. Therefore, how to transmit multicast data quickly, efficiently, and at low cost, and how to ensure the service quality of multimedia applications has become an important issue that network operators care about. [0003] After searching the existing literature, it is found that the traditional multicast technolo...
