The Transport Layer

The Transport Layer is related to movement of data. We know that movement essentially requires control. Movement is monitored to make it meaningful. 

When the  data exchange session is in swing, controlling  the movement of data becomes important. 

We control from near. We can control from far. The Transport Layer is known to control from far. The nature of control exercised by the Transport Layer is of general type. Such type of control is performed by well known methods.

It is the responsibility of the Transport Layer to efficiently perform its task. The Transport Layer must be thanked for the degree of reliability it brings to the transportation of data. This transportation is marked by a level of accuracy. 

Transportation accuracy means: the data sent, is the data received. The flow of data is flawless ( free from errors and mistakes ).

The regulation of communication activity between two Computers serves to enable transfer of data. 

The regulatory control performed refers to the active participants  ( Computers related to data transfer process ) in a general way. The regulatory reference that is made addresses the Computers uniformly. No particular reference to Computers can be seen.

The control exercised by the Transport Layer is focused on ordered transportation. There is a structured flow of data. For maintenance of flow connection lines are used. These communication lines are able to guide data during data transmission. 

As the Transport Layer functions in a location ( of Computers) independent manner, the control exercised results in a measurable accuracy, but may not provide total correctness. Further corrections related to the transmission are possible by the lower layers lying below the Transport Layer.

We can say that the macro control requirement of communication is fulfilled by the Transport Layer. Standard Principles of communication that enable a data exchange session  are practiced.

Interface Message Processor ( IMP )

Interface Message Processor ( IMP ) is a special purpose Computer. The Processor plays a vital role in Host-to-Host communication. IMP is placed between Host Computers.  IMP helps Hosts to exchange information. IMPs ( Interface Message Processors ) form a group. The group dedicates itself towards reliable transmission of Packets. _________________________ Note: An Interface Message Processor can be supposed to have a face. Firstly this supposed face of IMP is in the direction of the first Host, which sends the  message. Secondly, this face is turned towards the other Host.  Now, the IMP,  with its face turned around, communicates with this other Host.  Transformed message from IMP is communicated to this Host. __________________________ Message ( a piece of information ) sent from the Host ( source of information  ) is transformed into Packets. Transformation of the message into Packets is performed by an IMP. These Packets are forwarded to the receiver H...

Understanding Distribution

Distributed presence means that more than one object is there. Also, these objects are situated at more than one location.  One object may establish communication with another object. The first object may deliver some message. The message can be received by another object. It can be said that object distribution is successful, as one object has succeeded in delivering a message. The second object has successfully received the message. Two objects are at a distance. Communication brings them closer. The successful communication has served to highlight that the idea of distribution is meaningful. Distribution helps exchange of information. Many different objects can form a group.  Two groups can occupy different locations.  It may happen that at a particular location there are several objects. But, all these objects talk among themselves.They talk among themselves and make things happen.  There is a resultant of this talk process. All the communicating objects  at...

Message Switching

Message is a piece of information. Switching means movement.  In a Network there are a number of nodes. Nodes are vital junctions of a Network. Message Switching means transmission from one node ( one point ) of a Network to another node ( another point ). So, transmission is from point to point. Transmission from one point to another point is a single hop ( jump ). Message Switching means switch over of a Message. In one step of Message Switching,  Message switches over from one node to another.  The two nodes involved in a Switching operation are on the same Network. It cannot be that the beginning node ( source node) is on one Network and the second node ( sink node ) is on a different Network. In a point to point ( one junction to another junction ) transmission, a Message travels a part of its journey. Message moves from previous point to next point. The Network is Point-to-Point Network. A Switching activity means movement of a message. Indeed, the Message has mov...
