终端通信接入网网络资源分配策略研究

Research on the Network Resource Allocation in the Communication Terminal Access Network

在不改变现有国家电网通信网中各种体制网络结构的前提下,通过增加网络融合网关和终端接入网关两种功能实体,提出了一种双通信代理机制的异构网协同融合传输方案,并由此设计实现了基于时延的负载感知的异构网络资源分配算法,实现了多业务综合接入及多网络动态协同环境下的网络资源分配技术。数据分析表明该算法在平均时延、网络开销及丢包率等方面优于均匀分配算法、定时反馈的负载感知流量分配算法。

A new scheme for cooperative transmission design of heterogeneous networks with dual communication mechanism is proposed,by increasing two functional entities：the Network Integration Gateway（NI-GW）and Endpoint Access Gateway（EA-GW）,without changing the existing network structure system in communication network in State Grid.Therefore,a resource allocation algorithm based on time delay for load aware heterogeneous network is proposed,and multi service integrated access and multi network dynamic cooperation are achieved.In comparing with the Even Allocation algorithm and Timing Feedback Allocation algorithm,the proposed scheme improves the average delay,network overhead and packet loss probability.
