The current trend is to integrate a constantly increasing number of services in the same
communication network. Some services have very high resilience requirements, while other …

Feature Issue on Next-Generation WDM Network Design and Routing (WDMN) We present
a solution for IP-centric communication at the optical layer through a combination of a …

Network virtualization (NV), considered as a key enabler for overcoming the ossification of
the Internet allows multiple heterogeneous virtual networks to co-exist over the same …

The problem of how to provide, in a cost-efficient manner, high levels of availability and
service differentiation in communication networks was investigated in Tipper (Telecommun …

The concept of providing differentiated classes of resilient services over communications
networks has received a lot of attention in the literature. A number of proposals tried to …

We introduce a new mechanism to provide multi-failure survivability based on p-cycles. This
mechanism called MFS (multifailure survivability scheme) consists of two stages: off-line …

We study an idea for efficient integrated protection of an IP over WDM network using the
spare capacity of span-protecting p-cycles to provide protection against both optical link …

Multilayer network design has received significant attention in current literature. However,
the explicit modeling of IP/MPLS over OTN over DWDM in which the OTN layer's …

This paper addresses the problem of achieving a balance in satisfying a network service
provider's requirements: maintaining an acceptable call acceptance rate, satisfying …

In multilayer networks, protection can be accomplished in any of the layers. However, which
layer to protect most remains an important problem. In this paper, we consider a three-layer …
