In this topic, you will learn about, Buffering.

Buffering: A link has some capacity that determines the number of messages that can reside in it temporarily. This property can be viewed as a queue of messages attached to the link. Basically, there are three ways that a search for a queue can be implemented.

  • Zero Capacity: The Queue has a maximum length of 0. It is also known as a message system with no buffering. In this, the two processes must be synchronized for a message transfer to take place.
  • Bounded Capacity: The queue has a finite length n thus, almost n messages can reside in it.
  • Unbounded Capacity: The queue has potentially infinite length. Thus, any number of messages can wait in it. The sender is never delayed.
