Packets (information technology)

network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules

method for transmitting data over a computer network

formatted unit of data carried by all packet-switching networks

American engineer (1926–2011)

computer network equipment or software that analyzes network traffic

network messaging to multiple recipients simultaneously

In electronics and telecommunications, jitter is the deviation from true periodicity of a presumably periodic signal, often in relation to a reference clock signal. In clock recovery applications it is called timing jitter. Jitter is a significant, and usually undesired, factor in the design of almost all communications links.

size of the largest network layer protocol data unit that can be communicated in a single network transaction

data transmission unit

A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connectionless communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not be guaranteed by the network.

reduced quality of service due to high traffic on a computer network

method of designing modular communication protocols in which separate functions are abstracted from their underlying structures

means of transporting data over a packet-switched network so as to emulate a dedicated physical link between nodes

processing that examines network data

unit of information transmitted between peer entities (at the same layer) of a computer network

Transmission Control Protocol parameter

connection tracking network security system

British computer scientist (1924-2000)

transmitted data not making it to where it's supposed to go

place in a network where incoming traffic is silently discarded without informing the source

Ethernet frame with more than 1500 bytes payload

error-detecting code in some data-link layer communications protocols

interface to data link layers on a Unix-like system

a form of firewall that controls input/output or system calls of an application or service

packet switching method

historical network in England pioneering packet switching

type of computer security exploit

type of denial-of-service attack in which a compromised router deliberately discards packets

type of attack in computer networking

communications device

intentional dropping of network packets during congestion

smallest entity of data exchanged using the Internet Protocol over an IPv6 network

dividing a data packet into smaller units (frames)

sequence of packets from a source computer to a destination, which may be another host, a multicast group, or a broadcast domain

any Internet Protocol packet on the public Internet with a reserved IP address as source or destination; which must be dropped.
