The Research on Designs of Multiple Flow Tables in the OpenFlow Protocol
Ligang Dong, Long Chen, Bohan He, Weiming Wang · 2018
With the increase of network services, the scale of the flow table in the OpenFlow switch tends to increase rapidly, which makes it difficult to store flow tables in the limited memory of the switch, thus becoming a bottleneck of the SDN development. In order to reduce the storage space of internal flow tables in the SDN switch, this paper proposes two novel designs of multiple flow table based on the specific values in the matching field and logical relationship between matching fields.
