Routing in multilayer optical networks can be made efficient if label switched paths are searched in a wavelength graph that represents the state and the switching facilities of the network devices very accurately. Maintaining the wavelength graph by using the conventional link state advertisement control mechanism leads to scalability problem. Much of the link state information is, however, redundant...
A collection of slides from the authorpsilas seminar presentation is given. In particular the authors discuss multilayer networks, overlay models, peer model, routing in the optical and MPLS layers, min-phys-hop routing and simulation results.
A collection of slides from "Network resilience requirements and algorithms for multicasting and broadcasting digital TV" conference presentation is given.
The paper presents a collection of slides which discuss multipath routing, multipath protection resilience scheme, shared risk link groups, improved MPP (IMPP) linear program, simulation networks, path properties and protection.
Shared segment protection (SSP), compared with shared path protection (SPP), and shared link protection (SLP), provides an optimal protection configuration due to the ability of maximizing spare capacity sharing, and reducing the restoration time in cases of a single link failure. This paper provides a thorough study on SSP under the GMPLS-based recovery framework, where an effective survivable routing...
The modern, optical bore metro and particularly core networks consist of multiple layers, where multiple different networking technologies are stacked one over the other. In this paper we assume an IP/MPLS layer over an DWDM layer, both controlled jointly by one vertically integrated GMPLS control plane. To better utilize network resources, smaller, upper-layer traffic streams are multiplexed into...

The Internet consists of a collection of more than 21000 domains called Autonomous Systems (AS) operated mostly under different authorities (operators/providers) that although co-operate over different geographical areas, they compete in a country or other area. Today BGP is the de facto standard for exchanging reachability information over the domain boundaries and for inter-domain routing. The GMPLS...
