| | Packet switching - Wikipedia, the free encyclopedia |
 | | In computer networking and telecommunications, packet switching is the now-dominant communications paradigm, in which packets (units of information carriage) are individually routed between nodes over data links which might be shared by many other nodes. | | | ATM is another hybrid technology, which uses cell relay instead of packet switching. | | | This contrasts with the principal other paradigm, circuit switching, which sets up a dedicated connection between the two nodes for their exclusive use for the duration of the communication. |

| | Packets and Packet-Switching Networks (Linktionary term) |
| | A packet-switched network is an interconnected set of networks that are joined by routers or switching routers. | | | Packets have a header and a data area. | | | Packets are broken up into frames for delivery across a network; but, when the frames reach the next router, the packet information is examined by the router and a decision is made about how to forward the packet across the next link. |

| | Communication processor for a packet-switched network - Patent 4979100 |
| | In packet-switched networks, packets in the form of blocks of data are transmitted from a source--such as a user terminal, computer, application program within a computer, or other data handling or data communication device--to a destination, which may be simply another data handling or data communication device of the same character. | | | Packet switching arose, in part, to fulfill the need for low cost data communications in networks developed to allow access to host computers. | | | The switches used in the Telenet public network and various of its private networks are members of the multiprocessor TP4000 (sometimes referred to in abbreviated fashion as TP4) packet switch family. |

| | Network Core |
| | Since the amount of header information would be approximately the same for a message or a packet, the amount of header overhead per byte of data is higher for packet switching than for message switching. | | | But while the first packet is being moved from the first switch to the second switch, the second packet is simultaneously moved from the source to the first switch. | | | With packet switching, if there are 35 users, the probability that there are 10 or more simultaneously active users is less than 0.0017. |

| | For example, if a recent measure of packet delay is within a given range of an average packet delay statistic, the network is likely in a stable quiescent state and it is typically unnecessary to frequently determine the optimal codec. | | | The object of the present invention is to dynamically select an optimal codec used to encode the speech data for communication through the IP network, as a function of QoS statistics of the IP network. | | | One of the deficiencies of IP networks, however, is that such networks are not inherently suited to the transport of voice information. |

| | Several network layer protocol addresses can be mapped to a single X.121 address as described in RFC 1356. | | | Layer 3 is concerned with DTE to DTE (router to router) connectivity. | | | Because a router acts as an X.25 host, it must be configured as a DTE and the X.25 switch is the DCE. |

| | Satisfying High Quality Requirements of Videoconferencing on a Packet-Switched Network |
| | Since devices and network access delays depend in a non-linear manner on their utilization level, in order to fairly distribute loss and delays among devices and protocol entities, it is mandatory to maintain each device utilization level under its critical threshold. | | | Already known results can be exploited in order to optimize the network performances; e.g. | | | The results obtained from this point of view by RTP are very encouraging, as it is possible to deduce from figure 6, where a 20-second sequence of the network end to end delay is compared with the corresponding video frame end to end delay. |
