MPLmS实现IP的服务质量

Implementation of QoS on MPLmS

服务质量(QualityofService,QoS)保证是IP网发展的一个巨大挑战。尽管增加带宽能够改善因特网的服务质量,但仅限于目前“尽力而为”的服务模式,无法满足新应用的特点与需求。文章提出MPLmS(多协议标签波长交换)实现IPQoS的方案,探讨IP包格式与MPLmS格式的映射关系,使IPQoS能够通过MPLmS直接在IPoverWDM网络上得到相应的传输服务保证。

QoS guarantee is a great challenge for IP network's development. The quality of Internet service may be improved by increasing bandwidth, but it is only located in the model of 'best effort'; it can't provide enough bandwidth to the requirement of the new application. In this paper the implement of QoS on MPLmS is introduced, and discussing the mapping between IP structure and MPLmS structure. So the mechanism of IP QoS in the IP over WDM can come true by MPLmS.
