A collaborated IPv6-packets matching mechanism base on flow label in openflow

Abstract

Software Defined Networks (SDN), the separation of a network device’s control and data planes, do not need to rely on the underlying network equipment (routers, switches, firewall).It is a new network which collaborated IP and a lot of relevant technical content. The control of SDN is completely open, the user can customize any rule strategy to achieve network routing and transmission, which is more flexible and intelligent. Internet Protocol version 6 (IPv6), with the 128-bit address, is the next generation Internet. In this paper, we present a Flow Table structure by using Flow Label and a matching approach which use Flow Label within IPv6 protocol to decrease the size of Flow Table with OpenFlow and the time of forwarding IPv6 packets in SDN based on OpenFlow. The simulations and analyses show that this flow table mechanism performs better.
