One of the challenging issues in optical networks is call blocking and it increases with the
number of connection requests due to the limited number of wavelength channels in each …

The elastic light-trail technology reigning the recent trend for data communication in elastic
optical network (EON) prominently. Here, the Orthogonal Frequency Division Multiplexing …

A light-trail in a traditional ITU− T fixed wavelength grid optical network is a generalization of
a lightpath. Multiple nodes in a light-trail are allowed to communicate each other along the …

An elastic light-trail, the advanced version of a traditional light-trail, is one of the most recent
dynamic traffic grooming technologies in an elastic optical network. In such networks …

With the development of multimedia services in Internet technology, there comes a big gap
between bandwidth utilization and the blocking probability for multicast requests in the …

Energy efficiency has been well recognized as an important objective in design of IP over
WDM mesh networks. While previous works always focus on energy minimization through …

In this paper, we design an optimization problem for grooming of multicast traffic requests in
WDM mesh networks. The objective is to minimize the network cost by minimizing the …

Today, in passive optical networks (PON) the major issue is call blocking and it is getting
worse as there is an increase in the number of connection requests but the wavelength …

Network survivability is an important factor in the design of WDM optical networks. In
dynamic provisioning context, a typical connection request may require bandwidth less than …

The dynamic multicast traffic grooming is an efficient way to minimize the utilization of
network resources such as wavelengths, transmitters, receivers and splitters and minimizing …
