Study on the Speed-Up of Communications Protocol Processing by Parallel Processing

根据研究实施计划，研究设计一种协议机，通过基于标准协议即TCP/IP协议的并行处理来加速通信协议的处理，以加快网络的有效传输速率。本研究的主要成果如下：通信协议处理模型及并行性提取：基于标准协议中的层次和虚拟概念，可以在按层次顺序排列的层内实现并行性，并通过并行处理实现加速。通信协议处理的动态分析：动态分析表明，在通信协议处理中，传输处理所需的时间非常重要，层与层之间的数据复制过程负担很大。此外，要提高有效传输速率，仅仅加快通信协议本身的处理速度是不够的，而且通信控制也是必不可少的。协议机体系结构的研究：考虑到按层次顺序排列的层之间可以应用的并行性，将空间并行处理和时效性并行处理相结合，构成了协议机的基本体系结构。针对通信控制的提速问题，指出了确认信号（ACK）的延迟是提速的主要原因，并提出了TCP/IP框架下的提速实现技术。原型协议机的开发：根据3中描述的协议机。，为加快数据复制过程，可采用专用硬件和新型互连网络。原型性能评估：通过协议处理时间与传输效率的关系，证实了加快协议处理速度对提高有效传输速率有显著效果。特别是，随着高速网络的不断搜索和扩散，加快协议的处理速度将变得更加重要。少

According to the research implementation plan, the research was conducted to devise a protocol machine to accelerate the communication protocols processing by parallel processing based on standard protocols, i.e., the TCP/IP protocols, with the goal of speeding up the network effective transmission rate. The following describes the major results of this research :1. Communication protocols processing model and parallelism extraction :Parallelism can be applied within the layers which are arranged in hierarchical order based on the hierarchy and virtual concepts in standard protocols, and acceleration can be attained through parallel processing.2. Dynamic analysis of communication protocols processing :Dynamic analysis shows that the time needed for transmission processing in communication protocols processing is essential, and the data copy process between layers is a heavy load. Moreover, to speed up the effective transmission rate, this cannot be attained by just accelerating the com … More munications protocols processing itself but also the communication controls which are likewise indispensable.3. Research of protocol machine architecture :Taking into account the parallelism which can be applied within the layers which are arranged in the hierarchical order, and the combination of the spatial and timely parallel processing constitutes the basic architecture of the protocol machine. Furthermore, with regards to speeding up by communication control, it was pointed out that the delay of the acknowledgment signal (ACK) is the primary cause, and the speed up implementation techniques within the framework of the TCP/IP methodology are proposed.4. Development of prototype protocol machine :In accordance with the protocol machine described in 3., to speed up the data copy process is by implemention to a dedicated hardware and using new type of interconnection network.5. Performance evaluation for the prototype :The relationship between the protocols processing time and transmission efficiency confirmed that speeding up the protocols processing will have a significant effect in improving the effective transmission rate. In particular, with the continuing search and proliferation of high speed networks, it will be indeed much more important to speed up the protocols processing. Less
