The paper presents a model of the real world vehicle routing and dispatching problem. In real world, vehicle travel speeds are varying with period of time and can not be expressed as exact values. So the time-dependent and fuzzy travel speeds are introduced into the model. A dispatching period is divided into some time slices and each time slice is designated a triangular fuzzy speed. The travel time...
The application level multicast overlay network (ON) is composed by the hosts based on the physics unicast links between them. The initial ON is a completely connectivity network, which make the multicast tree construction and routing is lower efficiency. For improving the ON routing performance, the ON links should be selected. Based on a new presented ON link selection model with reliability and...
BACnet (Building Automation and Control networks) is a standard data communication protocol for building automation and control systems. The purpose of the BACnet network layer is to provide the means by which messages can be transmitted from one BACnet network to another regardless of the BACnet data link technology in use on that network. BACnet routers are devices that interconnect two or more...
With the extensive application of IPv6 protocol, the traditional IPv4 routing table lookup algorithms no longer satisfy the need of routing forward in the IPv6 network environment. So we optimize the routing table lookup algorithm to adapt for IPv6 that employs Bloom filters to realize parallel longest prefix match. The algorithm efficiently narrows the scope of the search, reduces the average time...
With the mature technologies and products, the next generation network has been more and more concerned in China. Chinese main telecom operators are beginning to associate test or structural network in order to expand their market. The article advances a new theory to solve the failure of the current communication networks that is the implementation of the passive caller resumption. It settles the...
