Network performance analysis of Time-Triggered Ethernet based on network calculus for DIMA

• This paper describes the TTE network devices as network elements, and models different kinds of traffic flow of the network constrained by the DIMA architecture. • The arrival curve provided by network calculus is defined in TTE network in conformity with data flow, and then derived the service curve is defined according to service offered by TTE network. • The calculation is implemented under network calculus theory defined from equation, and vertical and horizontal deviations between both curves can acquire the maximum delay and backlog. • The calculation results include the buffer size required avoiding the packet loss for BE messages and maximum network delay for worst-case of mix-critical functions in TTE network. • This paper makes use of network calculus method to guarantee the QoS constraint, and analyzes the deterministic performance and improves the bandwidth utilization of TTE network.
