对ASON承载IP网的研究(下)

Research of ASON Carrying IP Network

随着业务的发展,IP网逐渐成为统一的多业务分组传送平台,应提供更为严格的可靠性保障机制,其目标不仅是要保障任何情况下的业务连通性,还要保证业务的QoS指标。ASON能快速地提供端到端连接,并能提供多种保护恢复机制,提高网络可靠性。如果采用ASON来承载IP网,则ASON可以为IP网提供保护恢复机制。本文主要探讨ASON承载IP网的需求,研究ASON为IP网提供保护恢复的可行性,从IP网和ASON的保护恢复现状、ASON为IP网提供保护恢复的技术和经济性方面进行详细的分析。

IP network is becoming a uniform package multi-service transport platform. It should provide more strict reliability mechanism, and its target is not only ensuring the service connection, but also ensuring the service QoS. ASON can quickly provide end-to-end connection, and improve the network reliability by multiple protection and restoration. If IP network is carried by ASON, ASON can provide protection and restoration mechanism for IP network. This article researches the requirement of ASON carrying IP network, and studies the feasibility of ASON providing protection and restoration for IP network. The analysis is including the protection and restoration status of IP network and ASON, the technique and economy of ASON providing protection and restoration for IP network.
