| Abstract(in English) | In hop-based burst-cluster transmission, multiple bursts are assembled simultaneously and sorted from the smallest number of hops to the largest one. With this method, the burst loss probability for a large number of hops decreases, improving fairness. The performance of this method has been evaluated in unidirectional ring networks, and the effectiveness of this method has been shown. However, in mesh networks, the amount of traffic on each link is not necessarily the same, and hence the performance of hop-based burst-cluster transmission degrades. In this paper, we propose dynamic burst ordering for the hop-based burst-cluster transmission to solve this problem. Here, each ingress node calculates the burst loss probability for each number of hops using ACK and NACK messages. Based on the calculated probabilities, the ingress node changes the order of bursts within a burst-cluster dynamically. It is expected that this method can improve local fairness for each ingress node. We evaluate the performance of the proposed method in tandem networks by simulation. Numerical examples show that the proposed method is effective for improving local fairness for each ingress node regardless of the amount of traffic on each link. In addition, it is shown that the proposed method improves global fairness. |
