Network Slicing on SDN using FlowVisor and POX Controller to Traffic Isolation Enforcement

Abstract

Virtualization network with Software Defined Network (SDN) infrastructure is a flexible and promising solution to simplify network management and configuration through improved network programmability and abstraction. With the higher level of abstraction that SDN provides, network administrators can more easily configure network services and manage traffic flows without having to configure a large number of individual network devices (switches and routers). In addition to having many advantages on offer, sdn also presents a number of new vulnerabilities and security potentials. Securityat SDN has not received much attention, considering it is very distinctive and unique, not least in the firewall. According to Dixit et.al [1] SDN-based firewall is said to be comprehensive when fulfilling 8 elements one of which is able to support multi tenancy, which allows a number of resources to be used togetherby a number of users. Therefore it is very important for every tenant to be isolated from other tenants. In this study, wediscussed about the enforcement of traffic isolation and openflow by network slicing method in SDN network using flowvisor. The result obtained that each tenant is isolated trafficfrom other tenants.
