基于网络协议控制隧道的IPRAN承载方案研究

随着4G LTE基站和政企客户的对带宽的需求迅猛增长，传统的移动回程网络无法适应移动互联网场景下的多业务综合接入的承载需求。为满足大带宽、高质量的业务接入需求，运营商采用新型回程网技术IPRAN实现对4G基站、政企大客户等业务的融合承载。为了实现IPRAN具备业务端到端保护，即接入、汇聚、核心侧任何节点的电信级保护，及高质量的要求，我们提出了一种基于网络协议控制的分布式新型MPLS-TE隧道，通过实验仿真结果分析，完美得解决了对承载隧道的可靠性和高质量服务要求。

A Network Protocol Control Tunnel Research in IPRAN carrying solutions

With 4G LTE base stations and government-enterprise customer traffic increased rapidly, the traditional mobile Internet access network cannot adapt to a variety of business scenarios demand integrated access bearer. To meet the high-quality, high-bandwidth, access and flexible access to critical business needs. Operators using the new IPRAN bearer network technology for 4G mobile technology backhaul, government-enterprise customer. In order to achieve IPRAN end protection with business, namely access, aggregation and core layers any node carrier-class protection, ensure business continuity, we propose a network-based protocol control MPLS-TE tunnel flexibility through simulation results analysis, the perfect solution for carrying tunnel was the reliability and quality of service requirements.
