An autonomous decentralized system and a series of methods for reducing the detection time of path failures in the system are developed. Computing devices in the proposed system are organized into at least three groups based on their connectivity of system's graph model. Each computing device is assigned three identification values associated with their group memberships. The identification values...
In this paper, the technology of auxiliary VLAN is discussed. When IP phones are connected to the existing switch-based campus area network, the data traffic and voice traffic are present on the VLAN at the same time. To avoid a significant reduction on the quality of the VoIP traffic, the voice traffic is separated from the data traffic on an auxiliary VLAN. In an IP PBX, there are three frame types...
Web-content publishing is a service that is mainly provided by traditional client-server architecture. However, traditional approach requires much computer and network resources and therefore is relatively expensive. There are methods to publish web-content directly from users own computers. But in these approaches users have to keep their computers switched on continuously to publish for 24 hours...
After the great deployment and success of the Wireless Local Area Networks based on access points, which communicate by using wired links, the wireless world saw the birth of new technologies like Ad Hoc networks and Wireless Mesh Networks (WMN), which permit the flexibility, easy deployment and low cost. The first objective of these networks is to offer a seamless connectivity to mobile users. Nevertheless,...
Infrastructure meshed networks provide access to wireless clients that do not participate in traffic forwarding. This paper proposes minimalist instant handoff for wireless access networks (MIHAN), allowing for seamless movement of nodes in coverage areas, while maintaining connectivity. The approach of MIHAN is that all client frames, send in radio range of an access node, are received and forwarded...
