Sender requests connection from network. Other receiver agrees to connection. Computers interchange data through connection. One-endpoint requests network to split connection when transmission is done.

CONTINUOUS AND BURST TRAFFIC:

Networks handling video or voice are engineered to access and deliver continuous data at limited rate. Others are prepared to handle burst traffic typical of computer networks. Connection does not disconnected when no data is transmit.

SIMPLEX & FULL DUPLEX CONNECTION:

Some connection-oriented methods give full duplex while other allow on simplex connection. To interact using a simplex design a pair of devices must create two connections one from device A to device B and another from device B to A.

CONNECTION DURATION AND PERSISTANCE:

Connection can be created on demand set up permanently. There are two kinds:

• Switched Virtual Circuit or Switched Connection.
• Permanent Virtual Circuit or Permanent Connection.

Permanent connections are naturally hardwired and now managed at system unit time. In switched connections, device maintains permanent connection to network and networks create connections on demand.

Internal elements are switched networks is a switched data network.

SERVICE GUARANTEES:

Some connection-oriented networks give guarantees about the application that computer will receive. They may guarantee a throughput rate larger packet loss rate. For example, ATM gives statistical guarantee about performance.
