Abstract
Network Function Virtualization (NFV) and Software Defined Networking (SDN) are software-based approaches that can advance each other’s capabilities to build more scalable, agile, and innovative networks Kreutz et al. (Proc IEEE 103(1), 2004) [1]. This work’s framework Nascimento et al. (Acceleration mechanism for high throughput and low latency in nfv environments, pp. 1–3, 2017) [2] combines both technologies together for accelerating NFV environments. Although the results obtained from the evaluation are meaningful regarding performance, the network functions started relying on idle timeouts to release unused resources, which is very inefficient. In this article, we propose a mechanism to address this issue, allowing flows to be removed based on the state of the TCP sessions. The technique can significantly optimize the flow table utilization and improve scalability. The proposal was implemented and evaluated, where an expressive reduction of 80% in resources allocation was achieved in the laboratory.
