Dynamic network management method based on an OSEK network management mechanism

Abstract

The invention discloses a dynamic network management method based on an OSEK network management mechanism. On the basis of a direct network management method and an indirect network management method in a standard for realizing OSEK, a dynamic network management scheduler taking a specific network load as a threshold is designed, and the network load is divided into four levels; nodes for dynamic network management inquire the level of the network load regularly; and if the nodes find the change of the load level, the nodes dynamically switch the OSEK network management mode to overcome the conditions that messages on the network are not distributed uniformly according to time, and the network resources consumed by network management are increased along with the continuous increase of the nodes. The method has the advantage of adjusting the resources occupied by the network management according to the network condition so as to meet the requirement of real time environment.

Description

technical field [0001] The invention relates to a network management technology of an automotive electronic real-time control system, in particular to a dynamic network management method based on an OSEK network management mechanism. Background technique [0002] As the brain and central nervous system of the network, the network management system ensures the smooth communication between nodes in the network by monitoring and controlling the network, and makes the network achieve an effective balance between performance and consumption. In the field of real-time control of automotive electronics that requires high reliability and safety, the importance of network management systems is particularly prominent. High reliability and strong real-time performance require the network management system to ensure that the nodes in the network can be accessed by other authorized entities on the premise of ensuring smooth network communication, to allow temporary errors to occur, and t...

Problems solved by technology

When some nodes on the network need to occupy a large amount of bandwidth, if the normal communication of the nodes is affected due to the bandwidth occupied by the network management, the real-time performance and reliability of the system will be reduced, and the original intention of the network management will be violated. When the communication frequency is low, if the network management also adopts a low frequency method, it will lead to a waste of bus bandwidth and reduce the quality of network management

As the number of nodes on the network continues to increase, the network resources consumed by network management also increase, so static network management methods cannot adapt to the needs of dynamically changing network conditions.
