In this paper we study dynamically changing multicast trees (light-trees) in double-layer
optical networks. In this scenario, the continuous changing of multicast endpoints causes the …

Need for efficient and reliable network transport technologies has led to the introduction of
all optical networks and routing technologies. With the spreading of new, bandwidth …

The majority of papers on resilience deal with fast and resource-saving mechanisms that are
typically taylored to a certain networking technology or to a certain protocol. The aim of this …

The need for efficient and fast routing algorithms that can handle various demand types and
can offer protection is a key open question in next-generation optical networks. In the past …

This paper reports a summary of the joint research activities on Optical Core Networks within
the e-Photon-ONe+ project. It provides a reasonable overview of the topics considered of …

The evolution of multicast applications has speeded up. providers have to offer cheap and
reliable services for their customers. One way to achieve this is to use a restoration method …

In an optical network using the wavelength division multiplexing (WDM) technology, routing
a request consists of assigning it a route in the physical network and a wavelength. If each …

My theses cover two different areas of telecommunications, namely configuration and
resource optimization of optical networks and traffic identification and analysis of Peer-to …

We consider dynamically changing multicast trees (light-trees) in two-layer optical-beared
grooming-capable networks. The continuous changing of the tree ldquoleavesrdquo causes …

The distribution architecture of this type of services is explained as follows (Figure 1):• A
regional TV head-end receives all the national and international TV channels by means of …
