In this paper, we propose a novel concept of virtual resource chain for Software Defined Campus WLANs (SD-WLANs). A typical SD-WLAN is composed of three layers, i.e., infrastructure, access control and application layers. Firstly, the network control plane is decoupled from the forwarding plane, and soft-defined access points (SD-APs) merely execute the forwarding rules according to the instructions...
Routing is a critical problem in networking technology. The basic problem of QoS routing is to satisfy some network parameters constrained of many conditions which is not only a NP-complete problem but also QoS parameters are nondeterministic even fuzzy. Some practical heuristic algorithms are researched to solve such a problem. Based on Partheno-GA with Binary Coding, the network model and mathematical...
In order to solve the problem of state-extend in network multicast, aggregated multicast algorithm was proposed. Based on the existing routing algorithms, this kind of swarm intelligence algorithm (ant colony algorithm) can construct matching between aggregated trees and communication groups in the concurrent multicast groups and consequently improves the communication quality of network. Group-tree...
IP multicast often has great scalability problem with the router to keep forwarding state for every multicast tree passing through it. An aggregated multicast technology were proposed by Jun-Hong Cui and others in order to solve this problem, which enables the multicast groups that can be integrated to share one distribution tree so that the multicast state can be reduced efficiently. But this is...
