Traffic theory

Traffic balance in communication theory

The transport theory is a branch of Telecommunications . It examines the behavior of news sources and the interaction of this behavior with the telecommunications systems. The traffic theory is the mathematical description of the source behavior with the help of statistics . The terms of traffic theory can be explained most clearly using the example of telephony , but the regularities also apply to data traffic.

Telephony

Telephone subscribers try to establish connections to one another at different times. From the point of view of an observer, these attempts are mostly random, they generate a certain amount of traffic (occupancy time) Y. If this amount of traffic is related to a certain period of time , it is also called offer A. For economic reasons, the telecommunications systems cannot be dimensioned so that each conceivable offer is processed immediately or can be processed at all.

Terms

Traffic theory defines various terms with which the systems can be dimensioned so that the blockages do not exceed an acceptable level. The setting of this measure is arbitrary.

• market value
• Bundle (communications engineering)
• Rush hour
• power
• loss
• Remaining traffic
• Traffic model
• Erlang

A part of these processes can also be represented by the queuing theory .
