This paper introduces a novel ingress node design which takes advantage of video data partitioning in order to deliver enhanced video streaming quality when using H.264/AVC codec over optical burst switching networks. Ns2 simulations show that the proposed scheme delivers improved video traffic quality without affecting other traffic, such as best effort traffic. Although the extra network load is comparatively small, the average gain in video PSNR was 5 dB over existing burst cloning schemes, with a maximum end-to-end delay of 17 ms, and jitter of less than 0.35 ms.
本文介绍了一种新颖的入口节点设计，该设计利用视频数据分区，以便在通过光突发交换网络使用H.264/AVC编解码器时提供更高的视频流质量。Ns2模拟表明，该方案在不影响其他流量（如尽力而为流量）的情况下，提高了视频流量质量。尽管额外的网络负载相对较小，但与现有的突发克隆方案相比，视频PSNR的平均增益为5dB，最大端到端延迟为17ms，抖动小于0.35ms。
