Fiber Optics in Local Area Networks

Token-Less Protocols For Fiber Optics Local Area Networks

A family of LAN (Local Area Network) protocols is presented. The LAN consists of a pair of unidirectional fiber optic buses to which stations are connected via passive taps. The protocols provide round-robin bounded delay access to all stations. Contrary to most roundrobin access schemes, the protocols do not require transmission of special packets (tokens); rather, they simply rely on the dete...

A new SDN-based framework for wireless local area networks

Nowadays wireless networks are becoming important in personal and public communication andgrowing very rapidly. Similarly, Software Dened Network (SDN) is an emerging approach to over-come challenges of traditional networks. In this paper, a new SDN-based framework is proposedto ne-grained control of 802.11 Wireless LANs. This work describes the benets of programmableAcc...

Performance 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...

Wireless Local Area Networks

Wireless Local Area Networks (WLAN) findet man zunehmend als Trägersystem für die mobile Kommunikation mit Notebooks und Handhelds im Campusbereich und darüber hinaus. In diesem Tutorium werden die typischen Einsatzszenarien von WLANs vorgestellt, wobei auch ein Blick auf verwandte Technologien und Alternativen nicht fehlt. Die WLAN-Funktionsprinzipien werden an Hand der verbreiteten Standards ...
