摘要
随着3G/LTE网络的不断演进和发展,运营商对下一代移动回程网的可靠性提出了更高的要求,即要求具备业务端到端保护(接入、汇聚、核心层任何节点的电信级保护)。IP RAN是当前移动承载网领域主流的解决方案,它采用TE(流量工程)保护技术,用于提高网络运作效率与可靠性,并优化网络资源利用率和流量性能。本文就流量工程的两种保护技术进行了分析和比较。
With 3G/LTE evolving network and development operators a higher demand for next-generation mobile backhaul network reliability, and that requires business end-to- end protection, namely access, aggregation, any node in the core carrier-class protection. IP RAN is current mainstream solution in the field of mobile bearer network, and it adopts TE （traffic engineering） protection technology, which is used to improve the efficiency and reliability of network operations, and optimize network resource utilization and traffic performance. The two types of protection technology of traffic engineering were analysed and compared.
