WHEELNET: A Hybrid Ring/Star Architecture For Local Area Networks
نویسندگان
چکیده
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 architecture for a LAN called Wheelnet that combines a ring and a star topology. The resulting network architecture can lead to performance improvements over a ring topology and lends itself well to certain applications. © 2007Oklahoma Academy of Science

The paper presents optical LAN topologies which are made possible using an Arrayed Waveguide Grating Multiplexer (AWGM) instead of a passive star coupler to interconnect stations in an all-optical LAN. Due to the collision-free nature of an AWGM it ooers the n-fold bandwidth compared to the star coupler. Virtual ring topologies appear (one ring on each wavelength) if the number of stations atta...
متن کاملPerformance Improvement of Expanded Integrated Local Area Networks (RESEARCH NOTE)
In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
