In order to meet their stringent dependability requirements, most modern packet-switched
communication networks support fast-recovery mechanisms in the data plane. While …

This article describes the Survivable Network Design Library (SNDlib), a data library for fixed
telecommunication network design available at http://sndlib. zib. de. In the current version …

Deployment of new optimized routing rules on routers are challenging, owing to the tight
coupling of the data and control planes and a lack of global topological information. Due to …

OpenFlow, initially launched as a technology-enabling network and application
experimentation in a campus network, has a disruptive potential in designing a flexible …

Results of network planning and performance evaluation studies carried out by different
research groups are only comparable if they are based on the same or at least similar …

The software-defined networking (SDN) paradigm has simplified the management of
computer networks by decoupling data and control planes. Moreover, the separation of the …

Feature Issue on High Availability in Optical Networks The availability requirements for
today's networks are very high. Higher availability often comes with a higher cost. We …

In recent years, the emerging paradigm of software-defined networking has become a hot
and thriving topic in both the industrial and academic sectors. Software-defined networking …

This paper describes a set of typical transport network scenarios including their topology
and traffic parameters. Based on an existing population model an estimation of traffic …

Routing and wavelength assignment (RWA) algorithms must strike a balance between
finding routes with high quality of transmission (QoT) and finding routes that will not interfere …
