The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. [3] They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the ...
Network address translation between a private network and the Internet. Network address translation (NAT) is a method cane IP header of packets while they are in transit across a traffic routing device. [ 1 ] The technique was originally used to bypass the need to assign a new address to every host when a network was moved, or when the upstream ...
Zero-configuration networking.

v. t. e. Port Control Protocol (PCP) is a computer networking protocol that allows hosts on IPv4 or IPv6 networks to control how the incoming IPv4 or IPv6 packets are translated and forwarded by an upstream router that performs network address translation (NAT) or packet filtering. By allowing hosts to create explicit port forwarding rules ...
RADIUS is a client/server protocol that runs in the application layer, and can use either TCP or UDP. Network access servers, which control access to a network, usually contain a RADIUS client component that communicates with the RADIUS server. [1] RADIUS is often the back-end of choice for 802.1X authentication. [2]
