Recently, coflow has been proposed as a new abstraction to capture the communication patterns in a rich set of data parallel applications in data centers. Coflows effectively model the application-level semantics of network resource usage, so high-level optimization goals, such as reducing the transfer latency of applications, can be better achieved by taking coflows as the basic elements in network...
Traffic Engineering is an efficient tool to balance the network flows and, thus improving the network performance with limited network resources. The goal of traffic engineering is to find an efficient and robust routing to balance the flows with changing traffic. Multiple traffic matrices are good representatives of the changing traffic. The emergence of Software Defined Networking (SDN) provides...
Traffic engineering under OSPF routes along the shortest paths, which may cause network congestion. Software Defined Networking (SDN) is an emerging network architecture which exerts a separation between the control plane and the data plane. The SDN controller can centrally control the network state through modifying the flow tables maintained by routers. Network operators can flexibly split arbitrary...
High reliability is always pursued by network designers. Multipath routing can provide multiple paths for transmission and failover, and is considered to be effective in the improvement of the network reliability. However, existing multipath routing algorithms focus on how to find as many paths as possible, rather than their computation or communication overhead.
The hybrid algorithm based on the chaos optimization algorithm and ant colony algorithm is proposed in this paper. It is an approach to solve the optimal operation issue of a reservoir. According to the randomness and ergodicity of chaos, by searching all the chaos variables and walking all the statuses, the hybrid algorithm can effectively increase the computing efficiency, is easy to improve the...
