Network optimization for unified packet and circuit switched networks

Optimization of Circuit Switched Networks

Anders Svensson and Lars Reneby Department of Communication Systems Lund Institute of Technology P. O. Box 118, 22100 Lund, Sweden Abstract This paper describes a very general method which will be used for optimization of circuit switched networks in the design phase. The method used is based on a formal mathematical description of the network. Based on this description the performance of a num...

Unifying Packet and Circuit Switched Networks with OpenFlow

There have been many attempts to unify the control and management of circuit and packet switched networks, but none have taken hold. In this paper we propose a simple way to unify both types of network using OpenFlow. The basic idea is that a simple flow abstraction fits well with both types of network, provides a common paradigm for control, and makes it easy to insert new functionality into t...

A Proposal for Software-Defined Circuit-Switched Networking on Optical Packet and Circuit Integrated Networks

We present how software-defined circuit-switched networking (SDCN) should be realized on an autonomous-distributed controlled optical packet and circuit integrated (OPCI) network. We introduce a basic architecture suited for SDCN on the OPCI network. For OCS network virtualization, we propose to establish multi-wavelength logical paths as a C-plane slice. After creating a C-plane slice, unique ...
