| Callback Control Protocol | Callback Control-Protokoll (The Network Control Protocol that negotiates the use of callback over PPP links) |
| control protocol plug-in | Steuerungsprotokoll-Plug-In (A type of plug-in that enables a Windows Media server to communicate with clients and other servers through different network protocols) |
| Data Center Transmission Control Protocol | Data Center Transmission Control-Protokoll (A TCP-like protocol for data center networks which leverages Explicit Congestion Notification (ECN) in the network to provide multi-bit feedback to the end hosts) |
| Encryption Control Protocol | Encryption Control-Protokoll (The Network Control Protocol for negotiating the use of encryption over PPP links. ECP is defined in RFC 1968) |
| Internet Control Message Protocol | Internet Control Message-Protokoll (A required maintenance protocol in the TCP/IP suite that reports errors and allows simple connectivity. ICMP is used by the Ping tool to perform TCP/IP troubleshooting) |
| Link Control Protocol | Link Control-Protokoll (A PPP control protocol that negotiates link and PPP parameters to dynamically configure the data-link layer of a PPP connection) |
| logical link control and adaptation protocol | Logical Link Control and Adaptation-Protokoll (A protocol used in personal wireless network applications that provides connection-oriented and connectionless data services to upper layer protocols with protocol multiplexing capability, segmentation and reassembly operation, and group abstractions) |
| Real-Time Control Protocol | Real-Time Control-Protokoll (A scalable transport control protocol that works with the Real-Time Protocol (RTP) to monitor real-time transmissions to multiple participants over a network-for example, during videoconferencing. The Real-Time Control Protocol, or RTCP, transmits packets of control information at regular intervals and is used to determine how well information is being delivered to recipients) |
| Transmission Control Protocol | Transmission Control-Protokoll (The protocol within TCP/IP that governs the breakup of data messages into packets to be sent via IP, and the reassembly and verification of the complete messages from packets received by IP) |
