Ehab M. El Sabbagh, Mohamed Hussein, Ashraf D. Elbayoumy . Enhancing the End-to-end Link Performance of Traditional Satellite Ground Networks via Software-Defined Networking Controllers (POX/RYU). International Journal of Computer Applications. 177, 29 ( Jan 2020), 26-31. DOI=10.5120/ijca2020919771
Nowadays, the satellite networks with communication systems of terrestrial network undergo an augmentation of traffic flow which is one of our main issues. We oppose in vertical integration of the traditional networks a usual inflexible and inefficient quality of services’ (QoS) parameters as, latency and throughput. Recent technologies are rapidly being emerged and deployed, those are software defined networking (SDN) with its complementary, network function virtualization (NFV), additionally network virtualization (NV) which masks network resources with more flexibility in managing network via advanced programmability and OpenFlow controllability. Our proposal in this state of paper is a new programmable and centralized satellite network architecture based on SDN/NFV, composing of SDN layers that will correspond the functionalities of traditional devices in a virtualized behavior with a comparative performance results between OpenFlow controllers (POX/RYU) and traditional network to introduce enhanced services over satellite ground networks integrated through terrestrial networks. We disseminate our contribution regarding end-to-end (E2E) link performance and QoS parameters as latency calculation and throughput bandwidth-on demand by implementing different tests using “Mininet” open source network simulator and emulator tool to enhance augmentation of legacy in network’s link evaluations via OpenFlow controllers’ (RYU/POX).
