PROJECT TITLE :

Effective Flow Table Space Management Using Policy-Based Routing Approach in Hybrid SDN Network

ABSTRACT:

Through the use of software-defined NetWorking, forwarding devices can be managed more easily, and centralized control is achieved. Because everything is in one place, it is much easier and less expensive for a network administrator to program the various devices. The administrators of a network make an effort to switch their entire system over to switches that are compatible with SDN. In network architecture, a successful network scenario can be achieved through striking a healthy balance between SDN and legacy switching functions. A scenario of a hybrid network is presented here, in which the external boundary forwarding devices of the service provider network are switched out for SDN devices. This switch was carried out for the purpose of this research. Despite this, the other internal forwarding devices are still operating in the conventional manner. When combined, the benefits of software-defined networking (SDN) and legacy network design provide the network administrator with the opportunity to enjoy both sets of advantages. The architecture of the network makes use of a policy-based routing algorithm in order to make the most of the available free IP addresses from the pool of available IP addresses. Because of the relatively small size of flow tables, the technique enables an efficient use of the available flow table space, which is an essential component of SDN architecture. In order to determine how effective the algorithm is, performance metrics like network path stretch, throughput, latency delay, and other such things are compared to conventional SDN controllers like OpenDayLight, NOX, and POX. The results of the experiments show that the proposed method performs better than specific techniques that are similar to those that are considered state-of-the-art in the hybrid SDN domain.
