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.
RDMA over Converged Ethernet (RoCE) [1] is a network protocol which allows remote direct memory access (RDMA) over an Ethernet network. There are multiple RoCE versions. RoCE v1 is an Ethernet link layer protocol and hence allows communication between any two hosts in the same Ethernet broadcast domain.
The term port number was not yet in use. It was preceded by the use of the term socket number in the early development stages of the network. A socket number for a remote host was a 40-bit quantity. [4] The first 32 bits were similar to today's IPv4 address, but at the time the most-significant 8 bits were the host number.
The IP address/protocol/port number triple defines an association with a network socket. For publicly accessible services such as web and mail servers the port number is important. For example, port 443 connects through a socket to the web server software and port 465 to a mail server's SMTP daemon. [8]

The protocol partly relies on the remote party's rlogin client to provide information honestly, including source port and source host name. A malicious client can forge this and gain access, as the rlogin protocol has no means of authenticating the client is running on a trusted machine.
It is implemented with two UDP port numbers for its operations which are the same as for the bootstrap protocol . The server listens on UDP port number 67, and the client listens on UDP port number 68. DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement.
RFB ("remote framebuffer") is an open simple protocol for remote access to graphical user interfaces. Because it works at the framebuffer level it is applicable to all windowing systems and applications, including Microsoft Windows, macOS, the X Window System and Wayland. RFB is the protocol used in Virtual Network Computing (VNC) and its ...
