Traffic policing
From Wikipedia, the free encyclopedia
- This article is about the process used in communications networks. For the aspect of law enforcement work, see Highway patrol.
Traffic policing is monitoring network traffic for conformity with a traffic contract. An application that wishes to use the broadband network to transport traffic must first request a connection, which involves informing the network about the characteristics of the traffic and the quality of service (QOS) required by the application.[1] This information is stored in a traffic contract. If the connection request is accepted, the application is permitted to use the network to transport traffic.
The main purpose of this function is to protect the network resources from malicious connections and to enforce the compliance of every connection to its negotiated traffic contract. The network also has the capability to discard non-conformant traffic in the network (using Priority Control). Traffic policing in ATM networks is known as Usage Parameter Control (UPC) and Network Parameter Control (NPC).[2]
