- Abstract
- In this paper, we present evaluation results of Service Function Chaining implementation scheme using multiple flow tables of OpenFlow. With a single flow table in the implementation, the number of flow entries in the flow table significantly increases as the number of service chains increases. This results in looking up larger flow table and higher processing time in processing packets. We have addressed this problem in the previous work with the modified flow table construction scheme that exploits multiple flow tables. The proposed scheme classifies the incoming packets with VLAN tagging and switches can look up only the corresponding flow table to process the packets. By evaluating the proposed scheme, we identify its performance enhancement in terms of the number of flow entries and flow entry lookups.
