This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for bidirectional traffic. TCP usually uses port numbers that match the services of the corresponding UDP implementations, if they exist, and vice versa.
In computer networking, a port or port number is a number assigned to uniquely identify a connection endpoint and to direct data to a specific service. At the software level, within an operating system , a port is a logical construct that identifies a specific process or a type of network service .
A network tap is a system that monitors events on a local network. A tap is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. The network tap has (at least) three ports: an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic (send and receive ...
The keepalive packet contains no data. In an Ethernet network, this results in frames of minimum size (64 bytes [2]). There are three parameters [3] related to keepalive: Keepalive time is the duration between two keepalive transmissions in idle condition. TCP keepalive period is required to be configurable and by default is set to no less than ...
The basic requirements are at least a 1 GHz CPU, 1GB of RAM, and a 4GB hard drive. Two network cards are needed to connect to an Ethernet network. DSL, LTE and Wi-Fi are supported, too, with corresponding hardware. [8] The required computing power to run IPFire depends on the area of application.
EtherChannel between a switch and a server. EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches.It allows grouping of several physical Ethernet links to create one logical Ethernet link for the purpose of providing fault-tolerance and high-speed links between switches, routers and servers.
UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
This generates a storm of replies to the victim host tying up network bandwidth, using up CPU resources or possibly crashing the victim. [ 3 ] In wireless networks a disassociation packet spoofed with the source to that of the wireless access point and sent to the broadcast address can generate a disassociation broadcast DOS attack.
