Redundancy underpins resilient communications. Robust network architectures necessarily avoid single points of failure and rely upon distributed or decentralized control mechanisms. We will argue here that Internet Protocol (IP)-based networks possess the best-suited architecture for designing distributed networks and, consequently, that IP-based Cellular Networks enable the best solutions for ...

We consider two cases of the Survivable Network Design (SND) problem: given a complete graph Gn = (V,En) with costs on the edges and connectivity requirements {r(u, v) : u, v ∈ V }, find a minimum cost subgraph G of Gn that contains r(u, v) internally disjoint uv-paths for all u, v ∈ V . Our main result is an O (

Traffic grooming deals with efficiently packing/unpacking low-speed connections onto high-capacity trunks. We examine traffic grooming for optical mesh networks by reviewing grooming-node architectures, traffic models, grooming policies, novel graph models, survivable grooming, and hierarchical switching, etc. @2003 Optical Society of America OCIS codes: (060.4250) Networks; (060.4510) Optical ...

A prototype software system that implements a methodology for the strategic planning of survivable interoffice networks is presented. The software system determines strategic locations and ring types for Synchronous Optical Network ring placement. Two types of survivable network architectures are considered-1 : 1 diverse protection and SONET self-healing rings. The software considers three type...

Amidst the rapid growth of wireless broadband networks, little attention has been paid to wireless network survivability issues. We propose a survivable wireless ATM network architecture that allows it to survive from a single base station failure condition, by redirecting a failure cell’s traffic via its six neighboring cells. We present two failure-handling schemes for the proposed architectu...
