In a optical multidomain network, each domain needs to advertise its topology information to the other domains. Topology aggregation is an effective means to reduce the amount of the advertised topology information for each domain in large scale networks. The accuracy of aggregating the topology states is improved by using the approximation curves with limited amount of advertising topology information...
Survivability becomes an important issue in optical networks due to the huge bandwidth offered by optical technology. Many works have studied network survivability. The majority of these works are typically destined to single-domain. In this work we address the survivability in multidomain optical networks. This paper provides a classification of the existing protection solutions proposed for multi-domain...
In order to improve survivability of Multi-Domain Optical Network (MDON) and differentiate service reliability, this paper provides a protection mechanism with differentiated service reliability in MDON based on Conditional Risk Disjunction Degree (CRDD), called PDRC. Firstly, defines CRDD, provides Intra-domain virtual links Reflection arithmetic based on CRDD considering wavelength Continuity (IRCC)...
This paper proposes a novel Differentiated Domain Protection (DDP) algorithm to address survivability in multi-domain optical networks. In order to ensure the principle of transparent management in multi-optical domains, DDP abstracts the multi-domain optical networks to Virtual Topology Graph (VTG) to solve the inter-domain routing. In order to satisfy the survivable requirements of different domains,...
As DWDM networks proliferate there is a growing need to address the issue of distributed interdomain lightpath provisioning. Although inter-domain provisioning has been well-studied for packet/cellswitching networks, the wavelength dimension presents many additional challenges. This paper develops a novel hierarchical GMPLS-based framework for provisioning all-optical and opto-electronic multi-domain...
