Programmable and Scalable Software - Defined Networking Controllers
Programmable and Scalable Software-Defined Networking Controllers Andreas Richard Voellmy 2014 A major recent development in computer networking is the notion of Software-Defined Networking (SDN), which allows a network to customize its behaviors through centralized policies at a conceptually centralized network controller. The SDN architecture replaces closed, vertically-integrated, and fixed-...
متن کاملPractical routing and wavelength assignment algorithms for all optical networks with limited wavelength conversion
We present an Integer Linear Program based algorithm and a K shortest path based heuristic algorithm for solving the Routing and Wavelength Assignment problem in All Optical Networks with Limited Wavelength Conversion. These algortihms are executed on a random mesh National Science Foundation Network(NSFNET). Their performances are compared.
متن کاملRouting and Wavelength Assignment With Multigranularity Traffic in Optical Networks
We propose a novel switching architecture of multigranularity optical cross-connects (MG-OXCs) for dealing with multigranularity traffic in the optical domain. MG-OXCs can cooperate with the generalized multiprotocol label switching (MPLS) control plane, which provides the advantages of cost reduction, better scalability in physical size, and unified traffic management. Detailed discussions are...
متن کاملRouting and wavelength assignment with power considerations in optical networks
Previous studies have solved many variations of the routing and wavelength assignment (RWA) problem in optical networks under the assumption of perfect conditions regarding the power of a signal. In this paper, we investigate the RWA problem while allowing for degradation of routed signals by optical components. The problem is formulated as a mixed-integer non-linear program. We propose a two-p...
