- Abstract
- Service function chaining (SFC) enables the creation of composite network services that consist of an ordered set of service functions. For scalable and fault-tolerant SFC services, multiple service function instances should be deployed across networks and incoming flows should be distributed to multiple service function instances appropriately. In this paper, we formulate the flow distribution problem in SFC under resource constraints and evaluate its optimal solution in a realistic network topology generated by the GT-ITM topology generator. Simulation results reveal that the optimal solution can reduce the total flow latency significantly.
