NCFF: A Node Classification Fast Failover Scheme for OpenFlow Networks

Anjian Ai, Hua Qin, Yingxu Lai

Abstract— The ability to fast failover from failures has always been a crucial goal of network reliability in OpenFlow architecture. In this paper, we proposed a Local Reverse Back algorithm and a NCFF fast failover scheme to ensure fast failover from network link failures. Local Reverse Back algorithm selectively reverse traffic back to upstream node to make a comprehensive failover decision and it implements efficient link failure notification without extra detection mechanism. Based on categorizing switches of data plane into a set of types, NCFF establishes an efficient autonomic coordination mechanism between restoration and protection, which achieve a maximal utilization of pre-planned protection paths. To demonstrate the practical performance of the proposed scheme, we have implemented NCFF in our OpenFlow testbed. The numerical results verify that the NCFF enables faster reaction time and high survivability in various topologies.
