| | 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. | | | 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. | | | ATM is another hybrid technology, which uses cell relay instead of packet switching. |

| | The Evolution of Packet Switching |
| | The network switches, which are interconnected by voice-grade lines, store and forward from node to node data characters for up to 20 calls packaged in 66-byte blocks. | | | Packet switching was first demonstrated publicly at the first International Conference on Computer Communications (ICCC) in Washington, DC, in October 1972. | | | A datagram packet or end-to-end acknowledgment requires about 25 bytes of packet header in addition to the actual data (0-128 bytes) whereas only 8 bytes of overhead are required for similar packets on a virtual circuit. |

| | Packets and Packet-Switching Networks (Linktionary term) |
| | 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. | | | Packets are forwarded on-the-fly by routers, based on the most current best path to a destination. |

| | All-Optical Packet Switching for Metropolitan Area Networks: Opportunities and Challenges |
| | Moreover, for the all-optical packet switch to be competitive with the upcoming terabit high-speed IP routers or LSRs, it should operate beyond 10 Gb/s per wavelength to actually take advantage of the optical transparency of the payload data. | | | Delay lines are used between the input stage and the switch unit to give enough time to the header processing unit to configure the switch before the packets enter the switch unit. | | | In the case of IP packets, the client interface will first look at the IP header, assign an optical header to it according to the routing table, and transmit the packet to the next all-optical packet switching node. |

| | Network and System Concepts for
Optical Packet Switching |
| | The other node interface function deals with the packet header processing, which is done in the electrical domain, concerning reading the header to achieve the routing information by addressing lookup tables, and getting the new header content if header rewriting is required. | | | Photonic packet node interfacing functions must avoid any interference with the content and bit rate/coding of the payload in order to keep the transparency, which is a key issue of the optical packet concept. | | | The main function of an ATM switching matrix is to transfer the incoming cells from inputs to outputs. |

| | Packet Switching |
| | For packet switching, a data switching exchange (DSE) is required, which is a network node interlinking three or more paths. | | | The packet network inherent intelligence also allows graceful degradation of the network in the event of a node or path (link) failure. | | | The X.25 network is robust, in that if a problem occurs on the link, the packet nodes in the network will immediately reestablish the connection with the next packet that runs across the network. |

| | The Advanced Research Projects Agency Network (ARPANET) of the U.S. Department of Defense was the world's first operational packet switching network, and the progenitor of the global Internet. | | | The ARPANET was designed to survive network losses, but the main reason was actually that the switching nodes and network links were not highly reliable, even without any nuclear attacks. | | | However it is not, unless one means that these ideas influenced the ARPANET development by way of the RAND research papers. |

| | Packet Switching |
| | The main implementation of Datagram Switching network is the Internet which uses the IP network protocol. | | | In this way, packets arrive at the destination in the correct sequence, and it is guaranteed that essentially there will not be errors. | | | Each packet is treated as an independent entity, and its header contains full information about the destination of the packet. |

| | Maximum packet sizes vary from 64 bytes to 4096 bytes, with 128 bytes being a default on most networks. | | | Thus X.25 packets tend to be short - 128 0r 256 bytes as opposed to 1500 bytes or more for more modern protocols. | | | Modern protocols like Frame Relay or ATM take advantage of the low error rates of digital lines to avoid the latency problems of hop-to-hop error correction. |

| | Resilience in Optical Burst Switching Network |
| | The next important point is the wavelength conversion capability at each node, which is a future technology, dependent on the optical switching fabrics. | | | This occurs due to lack of optical processors complex enough for this type of calculations and therefore no O/O/O switches are present. | | | A new protocol called ‘Labeled Optical Burst Switching’ (LOBS), based on MPLS with the different extensions like GMPLS and MPλS, is presented for networks, based on Optical Label Switching (OBS, OPS, OCS). |
