Performance optimization literature in optical networks predominantly consists of single
objective optimization studies while often in practice multiple performance goals are to be …

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 …

In an optical WDM mesh network, different protection schemes (such as dedicated or shared
protection) can be used to improve the service availability against network failures …

The paper presents a tutorial on multilayer recovery methods. Emphasis is laid not on their
procedural operation, but rather on their quality assessment and differentiation based on …

This letter introduces a matrix-based approach to connection unavailability estimation in
shared backup path protection (SBPP). The proposed approach yields accurate results for …

Sub-band virtual concatenation (VCAT) technique can help improve spectrum utilization of
an elastic optical network (EON). On the other hand, availability is an important service level …

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 …

Backbone networks usually have some excess capacity (EC) to accommodate traffic
fluctuations and to avoid early capacity exhaustion. Network operators can exploit EC in …

Routing and wavelength assignment under availability constraints has been extensively
researched recently. Availability (or more precisely, steady-state availability) can be defined …

Survivability is a very important issue in telecom networks. Many previous works discuss
availability-guaranteed and service-differentiated provisioning for survivable network …
