Distributed hierarchical service network for automotive embedded system

Automotive embedded systems are connected with In-Vehicle Network (IVN) to provide complex functionality, flexibility and scalability. As many as automotive embedded systems are connected to the IVN, design of IVN is complicated. Also, Performance of IVN cannot be assured. This paper proposes distributed hierarchical service network architecture to solve the problems. Proposed network architecture has two layers, service management layer and service control layer. Service management layer manages services dynamically without a central supervisor and time-controlled scheme. Also, Service management layer can disperse network traffic. This makes design of IVN easier and assures performance of IVN. We show simple system architecture and service management scheme. Network service architecture we proposed can be easily applied to automotive embedded system from simple area to complex area with various IVNs.
