connection oriented transport service (OSI) (COTS)

The Connection Oriented Transport Service(COTS) is a connection-oriented transport service in a data packet network in which data transmission takes place via an existing connection.

Data transmission can only take place after a communication route has been established between the communication partners. The route between the communication partners can be permanently established, but it can also be virtual or temporary, and can be taken down again after data transmission. It can be a fixed connection or a dial-up connection.

In contrast to the connection-oriented transport services are the connectionless transport services( CLTS), which have no explicit route but take an individual route through the network.
