NCFF: A Node Classification Fast Failover Scheme for OpenFlow Networks
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.
