Connectionless Service
In a connectionless service, the packets are sent from one party to another with no need for connection establishment or connection release. The packets are not numbered; they may be delayed, lost, or arrive out of sequence.
Connection-Oriented Services
In a connection-oriented service, a connection is first established between the sender and the receiver. Data are transferred. At the end, the connection is released.
Connection Establishment Connection establishment involves the following:
Host A sends a packet to announce its wish for connection and includes its initialization information about traffic from A to B.
Host B sends a packet to acknowledge (confirm) the request of A.
Host B sends a packet that includes its initialization information about traffic from B to A.
Host A sends a packet to acknowledge (confirm) the request of B.
This connection establishment implies the steps i.e. bind, connect, listen & accept
What is message control system?
A method for controlling messages in a software system. The method activates a report-handling module when a subroutine has a message to send. The subroutine passes an identification to the report-handling module. The subroutine then passes a message and message level to the report handling module. The report-handling module then determines the message level to be reported for that subroutine, the process from which that subroutine is sending messages and the message level to be reported for that process. If the message level of the message compares correctly to the message level of the subroutine and the process, the message is reported.
