SDN-Enabled Time Sensitive Network Reconfiguration

Abstract

A general model and its solution are developed to determine how network routing can be reconfigured quickly without incurring transient congestion. Assuming both initial and target configurations are congestion-free, it is known that transient congestion may still occur during the reconfiguration process if links contain a mix of traffic flows following old and new routing rules, resulting from variation of switch reaction time and propagation delay differences among paths. We consider these factors by explicitly incorporating timing uncertainty intervals into the model. The model leads to an optimization problem whose solution represents a fast {in terms of actual physical time) congestion-free routing reconfiguration.
