J rgen Sv rke Hansen Torben Reich Birger Andersen Department of Computer Science, University of Copenhagen (DIKU) Universitetsparken 1, 2100 Copenhagen, Denmark fcyller,silmaril,[email protected] Abstract We present a design of a communication layer for mobile computing, which hides the complexity of using and switching between di erent means of communication, supports disconnected operation, and...

This paper reports the design and the implementation results of a Controlled Load service in a bridged/switched Local Area Network (LAN). In contrast to other approaches, the service was built based on traac aggre-gation and simple two level Static Priority scheduling within LAN switches. All complex control functions such as the per-ow packet classiication, policing and traac reshaping are onl...

This paper presents a new routing algorithm for a wireless ATM LAN. The LAN combines positive aspects of connection-oriented and datagram communications schemes in its usage of the ATM VP/VC concept. In this scheme, a set of VPI trees, rooted at each node in the LAN, are preestablished. This has the effect of emulating “connectionless” networking which simplifies handoffs and other mobility man...

This paper examines the importance of compatibility on buyer behavior in the market for LAN equipment over the period 1996 through 1998. I provide evidence that switching costs drive firm establishments to purchase LAN equipment from incumbent vendors. Because LAN equipment is a networked good, incumbency affects vendor choice both when it occurs at the same establishment and/or at other establ...

| The advent of switched LAN and ATM technology is dramatically altering today's networking environment. Given the preponderance of existing Ethernet networks today, high-speed, switched and/or full-duplex Ethernet and Ethernet LAN Em-ulation over ATM are extremely important, as is bridging between Ethernet and ATM. In this paper , we evaluate the performance of these newly emerging technologie...
