This is a standard that applies to wide area networks or WANs. It establishes a procedure for letting two computers on the network share a physical connection until they are done exchanging data.
The procedure for this is called handshaking – two machines exchange certain messages until the process is complete.
Technipages Explains Connection-Oriented Protocol
Handshaking means trading messages via the connection oriented protocol. These messages are generally things like “Okay, I’m ready,” “I didn’t get that; please resend,” and “Got it, bye.” These messages are traded in order to ensure that the data transmission is running and eventually completed successfully. COP essentially does a similar thing to IP or Internet protocol, though IP is connectionless. That means that it allows for the transmission of data without handshaking.
Neither device checks with the other whether the transmission was successful. This can save time in the transmission process, but with handshaking, faulty connections are less likely and recognised much sooner. Handshaking also establishes some context for the transmission. That means that roles are clearly assigned (sender and receiver, for example, or an equal exchange) and the beginning and end of the connection are clearly marked.
The protocol itself provides the framework for this handshaking exchange between whichever two devices are connecting via the network. Without it, the initial ‘greeting’ wouldn’t be possible and machines could not interact directly, or at least not without substituting a different protocol.
Common Uses of Connection-Oriented Protocol
- Connection oriented protocols employ a handshaking process.
- On a WAP, COP is the main framework for connecting devices to interact with each other.
- COP is a similar protocol to IP, though it connects machines in a different way.
Common Misuses of Connection-Oriented Protocol
- Connection oriented protocol is the tool used to connect a machine to a network.
