Network technology that breaks up a message into small packets for transmission. Unlike circuit switching, which requires the establishment of a dedicated point-to-point connection, each packet in a packet-switched network contains a destination address. Thus, all packets in a single message do not have to travel the same path. As traffic conditions change, they can be dynamically routed via different paths in the network, and they can even arrive out of order. The destination computer reassembles the packets into their proper sequence. Network protocols such as IP and IPX were designed for packet-based networks.
Network that does not establish a dedicated physical path, but transmits data in segments called packets. Packets are sent over the best available network connection and then re-assembled at the endpoint.
a network dedicated to the routing and delivery of data put in
A communications paradigm in which packets (messages) are individually routed between hosts, with no previously established communication path.
In a packet switched network, the data is broken up into small units called packets. Each packet contains the destination address and can be routed separately. Therefore, each packet may take a different path to the destination. Unlike circuit switched networks, packet switched networks allow the same data path to be shared among many users. Almost all traffic over the Internet is packet switched.
A data transmission network, shared by many users, in which multiple data transmissions can be sent concurrently. The communication paths are supervised and man-aged by the service-providing telephone company and are gener-ally equipped to provide alternate paths automatically and quickly without interruption of service.
A network that does not establish a dedicated path through the network for the duration of a session but, instead, transmits data in units called packets in a connectionless manner. Data streams are broken into packets at the front end of a transmission, sent over the best available network connection, and then reassembled in their original order at the destination endpoint.
A digital data transmission network that uses packet switching technology.
Network message protocol in which the message packets are self-routing. Each message packet contains a header that incorporates the routing information
A network in which data is transmitted in units called packets. The packets can be routed individually over the best available network connection and reassembled to form a complete message at the destination.
A communications network that uses packet switching technology.
A Packet Switched Network, or PSN, refers to the packet switched networks that existed before Internet. History can be divided into three eras: Early networks before the introduction of X.25 and OSI X.25 era when many PTTs introduced networks with X.25 interfaces Internet era when restrictions on connection to the Internet were removed.
