A design technique for reliable optical transport networks is presented. The network is first
dimensioned in order to carry a given set of static protected optical connections, each one …

A novel algorithm that seeks the 'shortest-widest'path and assigns lightpaths according to
their Q-factor is developed that exhibits better blocking performance, improved load …

Spare capacity allocation serves as one of the most critical tasks in dynamic GMPLS
networks to meet the stringent network availability constraint stipulated in the SLA of each …

Feature Issue on High Availability in Optical Networks The core idea of availability-based
routing consists of exploiting the availability as a link-state metric: this kind of approach has …

Providing resilient inter-domain connections in multi-domain optical GMPLS networks is a
challenge. On the one hand, the integration of different GMPLS domains to run traffic …

Since availability is an important quality-of-service (QoS) factor in mesh networks, different
service provision with availability guarantee have been discussed by many researchers in …

In this paper, we present two adaptive schemes, namely, global differentiated availability-
aware provisioning (G-DAP) and link-by-link differentiated availability-aware provisioning …

Service availability is an important issue in optical networks. Much research attention has
been drawn to the provisioning of reliable connections achieved by approaches such as …

Reliability is crucial for high speed backbone networks. Protection mechanisms are
therefore critical in the design of infrastructure networks. This paper investigates a new multi …

The main topic of this paper is the detection state of polarization changes to enhance data
security in fiber cable paths. The changes are generated by fiber manipulation or …
