ETBAC-Based Model in Media Oriented System Transport Network

With the development of network communicationtechnology, combination between network and automotiveelectronics industry has more and more extensively. The mainpoints on performance evaluation for this kind of multi-functionnetwork are bandwidth, resource utilization, security andreliability. Through the analysis of automotive electronicsnetwork topology and characteristic information transmissionpattern, we found that it will encounter many problems withtraditional network combination. One of them is the multi-nodesproblem. When multi nodes start at the same time, the networkwill cause congestion in the start-up period during the operationprocess. It will lead to the stagnation of network and reduce thesystem stability and security and reliability. In this paper, inorder to solve above problem, we propose a node-basedresolution strategy ETBAC (Embedding Task-based AccessControl) Model. This is an access control policy modeling byusing the top priority method HLF (Highest-level-First) toschedule the nodes in the media-oriented system network. Weuse CANoe 2640N to establish our network environment, andour implementation experiences connect it with other nodes, and through its real-time monitoring to record the network boottime. Experiments in our test demonstrate that this strategy canavoid network congestion problems effectively and accelerateset-up time during network booting.
