Novel Design of G.ODUSMP to Achieve Sub-50 ms Performance with Shared Mesh Protection in Carrier Networks
نویسندگان
چکیده
This paper describes the first practical implementation of shared mesh protection with <50 ms performance using the emerging standards G.808.3 & G.ODUSMP. It also presents the performance benefits of this implementation demonstrating 20-26% network cost savings vs. 1+1 protection and a maximum protection switch time substantially less than 50 ms.

Ring Speed Restoration and Optical Core Mesh Networks
Abstract Optical mesh networks using intelligent optical cross-connects are the choice for the next generation optical core. Mesh networks can be designed for fast and guaranteed recovery from single failures and can be designed to protect traffic more efficiently via shared mesh restoration. In this paper, we present a mesh restoration architecture for the optical core. The architecture provid...
متن کاملNovel Method for Designing Self-repairing Protection Trees in Mesh Networks
Protection trees have been used in the past for restoring multicast and unicast traffic in networks in various failure scenarios. In this paper we focus on shared self-repairing trees for link protection in unicast mesh networks. Shared protection trees have been proposed as a relatively simple approach that is easy to reconfigure and could provide sub-second restoration times with sub-optimal ...
متن کاملDesign of a novel congestion-aware communication mechanism for wireless NoC architecture in multicore systems
Hybrid Wireless Network-on-Chip (WNoC) architecture is emerged as a scalable communication structure to mitigate the deficits of traditional NOC architecture for the future Multi-core systems. The hybrid WNoC architecture provides energy efficient, high data rate and flexible communications for NoC architectures. In these architectures, each wireless router is shared by a set of processing core...
متن کاملA Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks
Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...
متن کاملAllocation of Protection Domains in Dynamic WDM Mesh Networks
In this paper, we solve the survivable routing problem in dynamic WDM mesh networks under the framework of Short Leap Shared Protection (SLSP). A novel algorithm called Cascaded Diverse Routing (CDR) is proposed. We also demonstrate a novel approach to solving the diverse routing problem in networks with dynamic traffic for the purpose of shared protection, called Iterative Two-Step-Approach (I...
