摘要

鉴于全球光传输网络的众多并购,利用GMPLS对SONET/SDH环进行分布式控制已成为一个重要的实体。主要要求是利用SONET/SDH拓扑的内置保护功能,在多供应商SONET/SDH网络中进行拓扑发现、路径计算和连接控制。在本文中,我们明确地考虑了这些需求,并对OSPF-TE - LSA处理规则和RSVP-TE信令机制进行了小的修改。为了说明其应用,我们以2F BLSR、1:1线性、1+1线性、无保护、4F BLSR和UPSR组成的时分复用网络为例。然后,我们将展示如何将示例网络中的每个链接发布为我们的更改,从而使远程节点或EMS/NMS能够自动发现每个网段的拓扑结构。我们还展示了在基于MPLS的IP网络中自动创建路径的方式与创建LSP的方式相同。我们提到了何时何地需要设置绕行LSP来提供保护,以及何时以及如何由SONET/SDH的底层保护方案来处理

Topology discovery and path provisioning in SONET rings using GMPLS
In the light of many mergers and acquisitions in the world of optical transport network, distributed control of SONET/SDH rings using GMPLS has become an important entity. The main requirements are topology discovery, path computation and connection control in the multi-vendor SONET/SDH networks utilizing the in-built protection capabilities of SONET/SDH topologies. In this paper we are explicitly taking up these requirements and making small changes in the OSPF-TE LSA processing rules and RSVP-TE signaling mechanism. To show its application, we take up an example TDM network consisting of 2F BLSR, 1:1 linear, 1+1 linear, unprotected, 4F BLSR and UPSR. We then show how each of the links in the example network is advertised with our changes to enable a remote node or EMS/NMS to discover the topology automatically for each network segment. We also show the creation of path automatically in the same way as the creation of LSP in an MPLS based IP networks. We mention when and where detour LSP setup is required to provide protection and when and how it is taken care by the underlying protection scheme of SONET/SDH
