In this article we will discuss Conversation Multiplexing, will make brief discussion on Multiplexing. In last article we discuss about Transport Layer Responsibilities.
Sending some types of data (for example, a streaming video) across a network, as one complete communication stream, can consume all of the available bandwidth. This will then prevent other communications from occurring at the same time. It would also make error recovery and re-transmission of damaged data difficult. The multiplexed signal is transmitted over a communication channel such as a cable.
The figure shows that segmenting the data into smaller chunks enables many different communications, from many different users, to be interleaved (multiplexed) on the same network. can be performed on the data in the segment to check if the segment was changed during transmission. The purpose of multiplexing is to enable signals to be transmitted more efficiently over a given communication channel, thereby decreasing transmission costs.
To identify each segment of data, the transport layer adds a header containing binary data organized into several fields. It is the values in these fields that enable various transport layer protocols to perform different functions in managing data communication. Multiplexing. Multiplexers, often called muxes, are extremely important to telecommunications. Their main reason for being is to reduce network costs by minimizing the number of communications links needed between two points.
