摘要
域间的流量工程策略有助于保证业务流的端到端QoS,提高网络资源利用率并实施跨域的快速恢复。本文介绍了域间流量工程的研究现状,并详细分析了不同的实现方法。最后指出了实施域间流量工程的困难所在及以后的研究方向。
Inter-domain traffic engineering is beneficial for supporting end-to-end QoS guarantees, optimizing network resource utilization, and ensuring fast recovery against link/node failures. This paper introduces the research progress on inter-domain traffic engineering, and analyzes various implement methods in detail. Finally we point out the problem of implementing inter-domain traffic engineering as well as the future work.
