DMT modulation has become a standard communications method for DSL and indoor LAN technology. By utilising the FFT it is able to overcome the problems associated with transmission over a nonflat communications channel. In DSL and indoor LAN technologies, the dominant source of performance impairment is crosstalk. Results are presented here in the context of DMT on an economical cabling scheme w...

Inl The interconnection of dissimilar LANs and devices over a high-speed backbone network can creat congestion at a destination LAN (output) gateway when more than one device or LAN attempt to simultaneously communicate with the same device or LAN. We address the issue of congestion avoidance in LANs interconnected by a high speed backbone. A congestion-avoidance scheme that requires input gate...

Information security, sometimes shortened to Info Sec, is the practice of defending information from unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording or destruction. It is a general term that can be used regardless of the form the data may take (e.g. electronic, physical). Virtual private networks (VPNs) offer low-cost, secure, dynamic access to pri...

This paper reports implementation and experimentation of a new IP rate control protocol proposed to alleviate congestion in the gateway of a LAN connected to external networks. Congestion is avoided by using explicit rate notification to LAN hosts via new ICMP control messages. In addition to avoiding congestion, the protocol also allows for greater fairness and priority in network traffic, whi...
