Today’s digital frontier can be described as the new Wild West with untested cutting-edge technologies finding their way into the public domain. With increased interest in Gigabit Passive Optical Networks (GPON) to provide LAN access, one question must be asked. What is the risk? Risks associated with traditional Ethernet LAN technologies are well known and documented. As is common with new tec...

Virtual LANs (VLANs) allow to interconnect users over campus or wide area networks and gives the users the impression as they would be connected to the same local area network (LAN). The implementation of VLANs is based on ATM Forum’s LAN Emulation and LAN/ATM switches providing interconnection of emulated LANs over ATM and the LAN ports to which the user’s end systems are attached to. The pape...

The authors describe the development of a software tool (named LAN-Designer) and its effectiveness in teaching and learning a local area network (LAN) design. The LAN-Designer is developed in Authorware 6.x (from MacroMedia) under MS Windows. The software is suitable for classroom use for courses involving LAN design at an introductory level. The paper concludes by discussing the strengths and ...

In this paper we propose a method of network traffic modeling that the traffic load of LAN in time is very high. In this method, an individual model of nodes on LAN performs target communication protocols consist of datalink layer and transport/network layers. The model works with the event driven state transition, then we can analyse network traffics with integration of transition times. The s...

The use of optical fiber as a transmission medium in computer local area networks (LAN) has lead to the design of new protocols to take advantage of the high bandwidth of fiber. Many of these new protocols have been designed for a ring topology LAN. There has also been significant research effort devoted to designing protocols for a star topology LAN. This paper proposes a novel hybrid architec...

Multiserver LANs, that offer many categories of services with absolute priority discipline, are investigated. The flows of user requests to servers are considered Poissonian. The optimization problem for LAN server set configuration is formulated; the goal is to minimize costs with servers, without exceeding the established mean response time for all users’ requests of different categories. Ana...
