STUDY ON JITTER BUFFERING MECHANISM BASED ON LARGE-SCALE CONVERGED NETWORKS WITH HETEROGENEOUS STRUCTURE

大规模混构融合网络包含了变化的网络集合,如GSM网络、3G移动通信网络、无线数传网络、卫星通信网络等多种通信网络,从而加剧了数据网络的抖动性。对此,提出一种网络抖动缓冲机制来解决混构状态下数据网络的剧烈抖动难题。针对融合网络层计算抖动减缓因子,并根据网络的非相关特性进行缓冲排名,该机制针对网络抖动的随机特性按周期进行操作;最后对该机制进行了仿真实验验证,结果表明:网络抖动缓冲机制能够较好地解决现有状态下的融合式网络的抖动问题。该研究对混构融合网络数据的网络抖动问题的解决有一定的参考价值。

Large-scale converged networks with heterogeneous structure contains changing network sets, such as various communication networks of GSM network, 3G mobile communication network, wireless data transmission network and satellite communication network, etc. , which exacerbates jitters of data networks. In light of this, we propose a network jitter buffering mechanism to solve the difficulty of severe jitter of data networks under the condition of heterogeneous status. It calculates the jitter buffering factor for converged network layer, and ranks the buffering according to non-correlation characteristics of network ; this mechanism operates periodically aiming at the random nature of networks jitter. Finally, we verify the mechanism with simulation experiments. Results show that the network jitter buffering mechanism can well solve the jitter problem of convergence networks in current state. This research has certain reference value on solving the network jitter problem of converged networks with heterogeneous structure.
