dc.description.abstract | Service function chaining (SFC) enables specific network flows to be processed through an ordered set of service functions. In this paper, we propose a two-stage failover mechanism to provide high availability (HA) in SFC. In the proposed mechanism, a secondary service function path (SFP) is pre-computed, which is maximally disjointed with the primary SFP, and a backup service function instance (SFI) is prepared for each service function. For a failure event, the first local repair stage is examined by means of the preconfigured backup SFI. If the backup SFI is not available and/or any link is failed, the second end-to-end repair stage is triggered by replacing the primary SFP with the secondary SFP. Simulation results demonstrate that the proposed failover mechanism can reduce the recovery time by 50%-75% compared to the conventional approach. | - |
