    • 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.
    • 本公开提供了诸如光传输网络(OTN),同步光网络(SONET),同步数字体系(SDH),以太网等光网络中的带宽碎片整理系统和方法。 特别地,本发明包括可以在信令和路由协议的上下文中使用的带宽碎片整理算法,以避免带宽碎片整理。 因此,本发明定义了以避免带宽分段并提供更好的网络利用的方式来计算连接的端到端路径的机制。 例如,本发明可以包括基于管理权重和分段成本的路径计算。 这可以在现有的信令和路由协议中实现,而不改变在拓扑发现中使用的现有协议消息。 此外,本发明优化可用带宽,允许更高带宽请求的可能性被允许。
