Migration of a process from one node to another node is known as process migration.

There are 2 techniques for migration.

1. Pre preemptive : Also called "process migration" The migration is done in between the process of execution.

2. Non - pre preemptive : Also called " code migration " The migration is done before the process begins execution.

The reason for source migration could be :

1. Because the source machine is not having resource.

OR.

1. The source machine is over loaded and hence requires clock to be executed.

A process involves code segment + resources segment + execution segment.

Binding can be initiated by sender or receiver.

In sender initiated code is with sender sends a query to data server is an example of sender initiated in which process binds to resource.

In receiver initiated : Receiver gets process migrated on demand.
