  Abstract

It has been recently proposed a method that guarantees jitter upper bounds by using a buffer near the destination, without time synchronization of the network. In this paper, we demonstrate that the latency and jitter upper bounds can still be guaranteed even when cut-through is impossible. Furthermore, it is shown that the proposed technique can be implemented with a simple small-scale embedded system to achieve zero-jitter. The experiments have been conducted in an ideal case and a realistic case. In the ideal case, the source, the destination, and the buffer are implemented in the same device and the network module in the other device. The realistic case implements the source and the network on a single device and the buffer and destination on the other device. In this case it suffers from clock drift between the source and the destination, and random latencies in the network. As a result of the implementation, we achieved zero jitter in an ideal situation and a level of jitter much smaller than the upper bound of jitter in a realistic environment. It has been shown that the proposed technology can guarantee the upper jitter bound only by software coding at end nodes, without a help from a special hardware or a network, and achieve zero jitter according to conditions.
