摘要:

提出了一种通用的异构网络多连接系统模型,并在有限样本条件下,借助拔靴估计法和贝叶斯估计法对时延的分布进行估计,以最小化多连接失败概率为优化目标,给出了最佳分流比例的计算方法。仿真结果表明,多连接可有效提升系统性能,采用最佳分流比例实现多连接时,子业务流之间可实现良好的同步。

Abstract:

The paper presents a common multi-connection system model in heterogeneous networks.The best traffic splitting rate is computed based on the bootstrap estimation and Bayesian estimation of the network delay,with minimizing the multi-connection failing probability as the optimization objective.The simulation results show that multi-connection can increase the system performance,and synchronization of the sub traffic is well achieved with the use of the best splitting rate.

Key words: heterogeneous networks;multi connection;synchronization;bayesian estimation;bootstrap estimation
