The term "transparent web caching" refers to cache technology in which web traffic is automatically intercepted and redirected toward one or more cache servers. The redirection of web data can be accomplished using L4 switches or routers. Being completely transparent to the user (no browser configuration is required) the service can be easily implemented and turns out to be scalable and fail-sa...

Most computing environments today consist of a number of workstations or personal comput ers PCs connected via a high speed in terconnection network These environments are usually called workstation clusters while acronyms like COWs Clusters of Worksta tions and NOWs Networks of Workstations are popular as well Although worksta tion clusters have the aggregate processing memory and I O capacity...

We describe the theory, design and ongoing prototyping of a wireless ATM LAN/PBX capable of supporting mobile users with multi-Mb/s access rates and multi-Gb/s aggregate capacities. Our proposed LAN consists of network nodes called Portable Base Stations (PBS) providing microcell coverage. The PBSs are designed to be low-cost, compact and high-speed and can be relocated conveniently. We employ ...

Wireless Communication has become one of the most popular types communication networks because many services it provides; however, experienced several challenges in improving network performance. VLAN (Virtual Local Area Network) is a different approach which enables administrator to create logical from physical network. By dividing large into smaller networks, technology improves efficiency, m...

IEEE802.11 wireless networks have become one of the most widely used networks. Due to open nature of wireless medium, hackers and intruders can make utilization of the loopholes of the wireless communication; as a result, there are many security threats associated with Wireless Local Area Network (WLAN). In this paper, we have worked an experimental analysis to study some of the well known atta...

This paper reports on the design and implementation of multi-criteria vertical handoff decision algorithms in a heterogeneous wireless wide area network (WWAN) and a wireless local area network (WLAN) environment. An “IPcentric Field Workforce Automation” project aims to ensure free movement of field workers between networks while always connected in an IP mode, and to allow a user to use one d...

the VAXcluster system to VMS version 5.4-3 increases tolerate and work around the availability of local network failures. area VAXcluster (LAVc) This paper describes the configurations by allowing availability features added the use of multiple local to local area VAXcluster area network (LAN) adapters (LAVc) support in VMS in the VAXcluster system. version 5.4-3. These Availability is increase...

Within the Institute of Electrical and Electronics Engineers, Inc. (IEEE), the IEEE 802 LAN MAN Standards Committee is developing air interface standards for wireless local area network (LAN), wireless metropolitan area network (MAN), and wireless personal area network (PAN) technology. These standards are enabling the development of an infrastructure for the Wireless Internet. This article was...
