End-to-end Delay Analysis of Aggregated Traffic of Heterogeneous Links in Command and Control Network

Aiming at the problem that end-to-end delay is difficult to accurately evaluate due to complex mul-tidimensional, instantaneous traffic arrival process and subsequent transmission, and time-varying system ser-vice process, an end-to-end delay analysis method for aggregation traffic of heterogeneous links in command and control (C2) network is proposed. By describing the constraint boundary of traffic arrival process and system service capability, the closed-form expression of end-to-end delay is obtained for time-delay sensitivity, bandwidth sensitivity, delivery by the best efforts and other heterogeneous traffic. The relationship between end-to-end delay and traffic burst degrees, number of series connection nodes and violation probability is verified by numerical analysis, which provides theoretical support for the construction of kill chain from any sensor to the best shooter.
