摘要： The present disclosure provides absolute route diversity (ARD) for mesh restorable sub-network connection protection (MR-SNCP) services. ARD addresses concerns in MR-SNCP by providing absolute path diversity between both paths (e.g., peer Sub Network Connections (SNCs)) of an MR-SNCP connection. If an ARD condition is not met, the peer SNC is not mesh restored and the MR-SNCP works with just one single SNC. The advantage of this approach is to reuse the bandwidth saved from ARD for other MR-SNCP, i.e. more efficient bandwidth utilization due to ARD for other MR-SNCPs, and better service quality guarantee (protection) in terms of planning and managing the network bandwidth.
摘要翻译： 本公开提供了用于网状可恢复子网连接保护（MR-SNCP）服务的绝对路由分集（ARD）。 ARD通过在MR-SNCP连接的两个路径（例如，对等子网络连接（SNC））之间提供绝对路径分集来解决MR-SNCP中的问题。 如果不满足ARD条件，对等体SNC不进行网格恢复，而MR-SNCP只能使用一个SNC。 这种方法的优点是重新使用ARD为其他MR-SNCP节省的带宽，即由于其他MR-SNCP的ARD而导致的更有效的带宽利用率，以及在规划和管理网络带宽方面更好的服务质量保证（保护） 。

摘要： The present disclosure provides bandwidth defragmentation systems and methods in optical networks such as Optical Transport Network (OTN), Synchronous Optical Network (SONET), Synchronous Digital Hierarchy (SDH), Ethernet, and the like. In particular, the present invention includes bandwidth defragmentation algorithms that may be used within the context of a signaling and routing protocol to avoid bandwidth defragmentation. As such, the present invention defines a mechanism for computing an end to end path for a connection in a manner that avoids bandwidth fragmentation and provides for better network utilization. For example, the present invention may include a path computation based upon administrative weight and upon fragmentation costs. This may be implemented in existing signaling and routing protocols without changes to existing protocol messages used in topology discovery. Further, the present invention optimizes available bandwidth allowing a higher probability of higher bandwidth request being admitted.
