An Optimization-based Approach for Flow Table Capacity Bottleneck Mitigation in Software-Defined Networks

Robert Bauer,
Martina Zitterbart

Abstract: Flow delegation is a flexible technique to mitigate flow table capacity bottlenecks in Software-defined Networks (SDN). Such bottlenecks occur when SDN switches provide insufficient flow table capacity which leads to performance degradation and network failures. Flow delegation addresses this problem by automatically relocating flow rules from a bottlenecked switch to neighboring switches with spare capacity. This paper introduces a new algorithm to efficiently perform flow delegation based on a novel delegati… Show more
