链路聚合技术在IPRAN中的应用研究

Research on the Application of Link Aggregation Technology in IPRAN

随着移网业务的爆发式增加,IPRAN网络逐渐出现汇聚层以上中继链路流量越限情况。为了解决这个问题,可以通过链路聚合技术聚合多个同类型端口来提高链路带宽,并同时实现冗余容错和负载均衡的功能,满足了移网业务对大带宽的需求。IPRAN网络承载的移网业务对实时性要求高,出现故障时要求快速检测、快速切换,保证数据不间断传输。在链路聚合技术实施基础上加载BFD双向快速检测功能,能进一步对网络进行优化,提高IPRAN网络的可靠性。

With the explosive increase of the mobile network service, the IPRAN network gradually shows the over limit of the relay link flow over the convergence layer. In order to solve this problem, it is possible to link multiple ports of the same type through link aggregation technology to improve the link bandwidth, and at the same time, redundancy tolerance and load balancing functions are implemented to meet the large bandwidth requirements of the mobile network service. IPRAN network carrying the network service carried by IPRAN net word requires high for real-time, and it needs fast detection and fast switching when the fault occurs, which ensures the transmission of uninterrupted data. Based on the implementation of the link aggregation technology, the BFD bidirectional fast detection function is loaded, which can further optimize the network and improve the reliability of the IPRAN network.
