Shruti Sharma, Amardeep S. G. Singh, Sharanjit Singh, Ramanpreet Kaur · 2016
SDN is an Up-Coming technology in a Mobile access networks, have great prospective to simplify the existing complex network and introduces new services and features. In SDN-based mobile access network, network is managed by central controller and responsibility of forwarding the packet is given to the SDN devices. In this article we discuss the problem in mobile access network like:-fast increase of mobile traffic from smart phone like devices, limited rule space in SDN mobile. Rule caching mechanism to improve the efficiency of network, rule replacement to improve the processing capacity of datacenter in mobile access networks. SDN controller is design to managed the 2-layer rule space in each SDN device. Cache prefetching also introduce with the consideration of user mobility.
