異構(gòu)環(huán)境下覆蓋網(wǎng)組播算法的研究
[Abstract]:Real-time multimedia services with strong delay constraints such as audio and video conferencing are an important application of overlay multicast technology. With the rapid development of mobile Internet, more and more users expect to access these services through mobile terminal devices, but the existing overlay multicast tree generation algorithm can not meet the needs of both terminal heterogeneity and service delay constraints. Therefore, a heuristic algorithm for multicast tree generation in delay constrained overlay networks is proposed. The algorithm introduces transcoding capability into the nodes of the common minimum delay multicast tree and takes into account the bandwidth consumption and service delay of mobile terminals so as to meet the constraints of link bandwidth and node transcoding capability. Simulation results show that compared with Transcasting, the proposed algorithm can achieve lower average service delay and better multicast tree robustness at a small bandwidth cost.
