The most troublesome problem in deploying streaming media service is the package-lost delay, which results in too much buffer, low-quality image and interrupted play.
At the present time, the most realistic approach is to use fiber delay line as optical buffer.
目前,在光域比较现实的还是采用光纤延迟线作光缓存。

The analysis shows that although loss probability decreases through expanding buffer capacity, delay and delay jitter increase, whose effect on QOS will not be negligible.
