为了实现在包括高损耗网络在内的各种网络上的快速文件传输，我们已经提出了使用PR-SCTP无序传输的分段文件下载方法。在丢包频繁的网络状况较差的情况下，使用PR-SCTP并配合合适的控制参数，可以减少由于退避而造成的传输等待时间，并且无序传送可以减轻队头阻塞的影响。现有的研究讨论了客户端合适的控制参数，而服务器端参数设置得当，所有客户端都可以享受快速下载。本文首先关注控制参数对服务器的影响，假设流量饱和，服务器始终保持其发送缓冲区已满，以消除客户端请求造成的延迟。然后我们在客户端的控制参数方面讨论了我们对客户端的请求方法的改进空间。我们提出的能够适应各种网络环境的建议应该是讨论自治自组织网络的最重要技术之一。
To realize quick file delivery on various kinds of networks including highly lossy ones, we have already proposed the segmented file download method using PR-SCTP with unordered delivery. In a poor network condition in which the packet loss occurs frequently, using PR-SCTP with suitable control parameters can reduce the transmission waiting time caused by the back-off and unordered delivery can alleviate the influence of the head-of-line blocking. The existing research discussed suitable control parameters on the client side, while all the client can enjoy the fast download if the server side parameters are set appropriately. In this paper, first, we focus on the effect of the control parameters on the server, supposing the saturated flow, in which the server always retains its sending buffer filled, in order to eliminate the delay caused by the client requests. Then we discuss the room to improve our request methods for clients in terms of the control parameters on the client side. Our proposal which can adapt to various network environments should be one of the most important techniques to discuss the autonomous self-organizing networks.
