本文提出了一种双层多中心多目发送保序机制，并在以太网和工作站环境中实现．通过将本方法与现有集中式、分布式和树型方式的比较以及对实验数据的分析，认为集中式虽然通信开销低、简单易实现，但坚定性差、并行度低；分布式方式虽然坚定性强，但并行度低、通信开销大、效率低；传播树方式效率虽然较前两种有所提高，但在根结点处同样并行度低、坚定性差，而且结构不灵活．本文提出的方法，避免了上述三种方式的缺点，并且具有坚定性强、并行度高和结构灵活、简单的特点．
In this paper, we propose a bi-level multi-center multi-purpose transmission ordering mechanism and implement it in Ethernet and workstation environments. By comparing this method with the existing centralized, distributed and tree-based methods and analyzing the experimental data, it is considered that although the centralized method has the advantages of low communication overhead and simple and easy implementation, it has poor firmness and low parallelism. Although the distributed method is firm But low in parallelism, large in communication cost and low in efficiency; although the efficiency of the propagation tree is higher than the former two, the same parallelism at the root node is low, the firmness is poor, and the structure is not flexible. The method proposed in this paper avoids the shortcomings of the above three methods, and has the characteristics of strong firmness, high parallelism, flexible structure and simple structure.
