It has been adopted by the IEEE as the basis for the 100BaseT Ethernet standard. A WAN technology capable of transmitting data, digitized voice and digitized image information. The underlying switching technology is based on the statistical multiplexing of data and voice in fixed length cells. Any of these packets could carry digital voice, data or digital image information. All the packets travel at Level Two of the OSI Model, and routing is performed on the basis of the Level Two addressing.
Fast packet is an effective way of making best use of available bandwidth.
It offers the benefits of conventional multiplexing techniques and circuit switching techniques. The switch used to route packets in a fast packet network is termed a fast packet switch. Also, fast packet technology can carry data transmissions that enter the network using a frame relay access method. For particularly high speed networking, an implementation of fast packet switching known as ATM is being commercially developed. Fault tolerance - A method of making a computer system or network resilient to faults or breakdowns to avoid lost data and downtime.
