This paper considers the characteristics of block-level success and loss runs for streaming services over wired-wireless networks in which forward error correction (FEC) is employed for packet-loss resilience. We develop a single-server queueing model where the packet-transmission process over a wireless link is modeled by a Markovian service process (MSP) with two states "Good" and "Bad". The queueing system has two input processes: a general renewal input process and a Poisson one. The former represents a streaming-packet flow, while the latter is for background traffic multiplexed at the queue. We investigate the dynamics of the system state during the interval from the arrival epoch of the first packet of the block to that of the last one, deriving the block-loss (resp. block-success) run distribution, i.e., the probability distribution of the number of consecutive block loss (resp. success). The analytical model is validated by trace-driven simulation experiments. Numerical examples show that when the traffic intensity is high, the moments of block-level loss and success runs are significantly affected by the volume of background traffic and the FEC redundancy, rather than the system capacity.
