Literature Review on Redistribution of Routing Protocols in Wireless Networks Using SDN Along with NFV

Abstract

AbstractThe Internet, metropolitan area networks (MAN), wide area networks (WAN), local area networks (LAN), wireless networks, and mobile networks have all seen technical breakthroughs in recent years. There are obstacles in developing and maintaining computer network infrastructures, as well as reducing operational and capital expenses, while achieving flexible convergence with these technologies. This paper focuses on reviewing the traditional computer networks and protocols to highlight the respective advantages and disadvantages. The advanced technology with OpenFlow networks includes the software defined networks (SDN). Such networks make use of modern environment due to which the competitiveness, scalability, applications and network services are achievable with the robust architectures. The underlying layer of network function virtualization (NFV) facilitates to use virtual machines such as switches, routers, firewall, and other network services. Some network administrators will only use NFV or SDN. The motivation of this paper is that to discuss various features of SDN and NFV that complement each other in terms of load balancing, scalability, virtual machines, network and application services, network security and reduced operational and capital expenditure cost in designing and maintaining the computer network infrastructures by using the redistribution of network routing protocol. Firstly, this paper discusses about the traditional wireless network technologies with Enhanced Interior Gateway Routing Protocol (EIGRP), Open Shortest Path First (OSPF), and redistribution of routing protocols on heterogeneous autonomous system. Followed by that, the OpenFlow protocol with SDN has been analyzed. In the third category, NFV is considered. As a continuation, the fourth category shows the trade-off to optimize the performance of wireless networks by improving the security, load balancing, and QoS along with the reduction in power consumption, capex and opex cost of computer networks.KeywordsWANLANRedistributionRouting protocolsHeterogeneousOSPFEIGRPVMOpenFlowSDNNFV
