In this paper, we design and evaluate algorithms for fast recovery from link failures in a smart grid communication network, addressing all three aspects of link failure recovery: (a) link failure detection, (b) algorithms for computing backup multicast trees, and (c) fast backup tree installation. To address (a), we design link-failure detection and reporting mechanisms that use OpenFlow to de...

This paper presents an experimental deployment of a multi-channel multi-hop wireless backbone network (WBN) with an OpenFlow-based traffic management method. Specifically, a set of APs, each of which uses a single but different channel, is connected by Ethernet and thus constructs a Virtual AP (VAP), thereby achieving a WBN with multiple channels. To flexibly control traffic flows transmitted o...

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...

Traditionally microwave backhaul has been configured and operated in a static manner by means of vendor specific management systems. This mode of operation will be difficult to adapt to the new challenges originated by 5G networks. New mechanisms for adaptation and flexibility are required also in this network segment. The usage of a signaled control plane solution (based on OpenFlow) will faci...

In this paper, we show our design and implementation method of contents anycasting using OpenFlow that is a promising future internet enabling technology. This method aims to improve the content server by enabling it serve more clients, also this method aims to make a more efficient use of the overall bandwidth available in the network by providing more flexible and dynamic redirection of conte...
