Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: An OpenFlow Switch (OF-Switch) stores the flow entries in a flow table, having confined capacity. The flow table is located in an extremely efficient associative memory called TCAM (Ternary Content Addressable Memory). Typically, a data center with 100 edge switches can generate up to eight million flows per second, whereas, an OpenFlow switch can save around 64K flow entries. A table-miss, generally, causes an exchange of messages beten an OF-Switch and the controller. This switch-controller communication (to install flow rule for every new flow) incurs severe overhead. Furthermore, if the flow table is full, then the controller-driven purging of flow entries induces substantial latency. Our objective is to address these critical challenges. ,  propose an efficient flow table management proposition through intelligent autonomous (within OF-Switch) eviction mechanism. Instead of relying entirely on the expiry period alone of a flow entry, our eviction strategy involves smart data logging using highly space-efficient data structure — Multiple Bloom Filters (MBF) to determine candidate flow entries to be purged. The MBF, located in Static RAM (SRAM), is designed in a Column-major order. It constructs the flow's importance based on reference locality and recentness; using simple and near optimal collision-free hash function.  have performed flow logging using a real packet trace, with an error probability of less than 1%. The simulation results show around 37% improvement (on average) in the table-hit ratio compared to Least Recently Used (LRU) method in 2K-size flow table.
