A generic term for improved packet-switching technologies such as frame relay and cell relay. Fast-packet techniques feature less functionality than traditional X.25 packet-switching; however, they provide higher speeds and lower processing costs. The following are feature groups for Fast Packet Switching: Feature Group A--provides line side access to telephone company end office switches with an associated seven digit local telephone number for an Interexchange Carrier's use in originating or terminating communications. Feature Group B--provides trunk side access to telephone company end office switches with an associated uniform 950-XXXX access code for an Interexchange Carrier's use in originating and terminating communications. Feature Group D--provides trunk side access to telephone company end office switches with an associated 101XXXX access code for an Interexchange Carrier's use in originating or terminating communications; no access code is required for calls to an Interexchange Carrier over Feature Group D switched access service if the end-user's telephone number is subscribed to that Interexchange Carrier.
An emerging, packet-orientated, digital technology that differs from traditional packet switching in a number of ways. The most obvious is that it transmits all data in a single packet format whether the information is video, voice or data. Fast packet switching uses short, fixed length packets (cells) & via hardware switching - is capable of speeds between 100,000 and 1,000,000 packets/second.
A WAN technology capable of transmitting data, digitized voice and digitized image information. It makes use of short, fixed length packets (or cells) that are all the same size. 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. It is one of the transmission technologies being developed for use with B-ISDN. 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.
Packet switching that supports both voice and data at T I speeds and above.
A packet processing technology that has streamlined protocol handling, including Frame Relay and ATM.
In telecommunications, fast packet switching is a packet switching technique that increases the throughput by eliminating overhead. Overhead reduction is accomplished by allocating flow control and error correction functions to either the user applications or the network nodes that interface with the user. Cell relay and frame relay are two implementations of fast packet switching.
