can be used for an entire private network. As network address translation modifies the IP address information in packets, NAT implementations may vary in...

version operated from 1973 until 1986. The NPL network was the first computer network to implement packet switching and NPL was the first to use high-speed...

In packet switching networks, traffic flow, packet flow or network flow is a sequence of packets from a source computer to a destination, which may be...

increase or even a decrease in network throughput. Network protocols that use aggressive retransmissions to compensate for packet loss due to congestion can...

a Christmas tree packet (also known as a kamikaze packet, nastygram, or lamp test segment) is a network message segment or packet with every option enabled...

Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused...

seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through...

a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that...

Berkeley Packet Filter (BPF; also BSD Packet Filter, classic BPF or cBPF) is a network tap and packet filter which permits computer network packets to be...

computer networking, packet delay variation (PDV) is the difference in end-to-end one-way delay between selected packets in a flow with any lost packets being...

the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the higher-level decision...

The GPRS core network is the central part of the general packet radio service (GPRS) which allows 2G, 3G and WCDMA mobile networks to transmit Internet...

In computer networking, a flit (flow control unit or flow control digit) is a link-level atomic piece that forms a network packet or stream. The first...

computer networking standard that allows a computer to be turned on or awakened from sleep mode by a network message. It is based upon AMD's Magic Packet Technology...

An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing...

In digital communications networks, packet processing refers to the wide variety of algorithms that are applied to a packet of data or information as...

communications networks, packet segmentation is the process of dividing a data packet into smaller units for transmission over the network. Packet segmentation...
