telecommunications and computer networking, a network packet is a formatted unit of data carried by a packet-switched network. A packet consists of control information...

packet switching is a method of grouping data into short messages in fixed format, i.e. packets, that are transmitted over a digital network. Packets...

A packet analyzer, also known as packet sniffer, protocol analyzer, or network analyzer, is a computer program or computer hardware such as a packet capture...

firewalls for network security were routers used in the 1980s. Because they already segregated networks, routers could apply filtering to packets crossing...

A network scheduler, also called packet scheduler, queueing discipline (qdisc) or queueing algorithm, is an arbiter on a node in a packet switching communication...

unit in computer networking and telecommunication. In packet switched systems, a frame is a simple container for a single network packet. In other telecommunications...

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

called a magic packet, which is commonly sent to all computers in a network, among them the computer to be awakened. The magic packet contains the MAC...

Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such...

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...

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...

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...

executing the applications that are the ultimate destinations for network packets that generated the interrupts. This technique improves locality of...

Internetwork Packet Exchange (IPX) is the network-layer protocol in the IPX/SPX protocol suite. IPX is derived from Xerox Network Systems' IDP. It also...

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...

A router is a computer and networking device that forwards data packets between computer networks, including internetworks such as the global Internet...

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...

standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in...

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

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

exists. A network packet is the basic unit of data in a transport stream, and a transport stream is merely a sequence of packets. Each packet starts with...

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

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...

NetScout. NetScout Systems acquired Network General in 2007. Network General developed the original network packet sniffer (The Sniffer) in 1986; it merged...

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