Towards Fault Tolerance Management Systems in SDN

Abstract

The issue of network operation, monitoring, and  availability in traditional network environments  has been one of the major challenges to addressing network administrators' struggles to deal with.  The capacity for the network to comprehend the  status and the performance of every node has been  one of the priorities amongst others for network  administrators to protect during troubleshooting  in their network. However, the growing use of  software-defined networks (SDN) technologies,  as well as virtualization, pave the way to the  solution of network operation, monitoring, and  availability of hardware and services in a network  environment. SDN has emerged with a novel  paradigm of network abstractions that is dynamic, able to monitor network performance and fault  management automatically, using its  programmable capability. This paper presents a  design of a fault tolerance management system for  SDN controller framework for small to medium sized networks capable of detecting controller  faults and nodes/links faultsin case entire network  access is unavailable. The fault management  system applies various approaches for fault  detection and recovery to ensure the reliability  and availability of the network resources.
