1.GAMMA网的设计原则对GAMMA网的设计,考虑了物理结构和逻辑结构两方面的特性.在物理结构上,本系统是采用高速光纤环状总线紧密连接起来的.这是因为:首先,我们着眼于高速通信子系统的实现,它可在几秒钟内传输达1兆字节的大容量文件.其次,在这个系统中,文件子系统可以看作是由后端处理机支持的.后端处理机的文件能从远程功能子系统存取.这样设计的环状总线能够和文件子系统的输入输出(I/O)通道一样快地传输数据,而不致成为本系统中的“瓶颈”.第三,
1.GAMMA network design principles GAMMA network design, taking into account both the physical structure and logical structure characteristics.In the physical structure, the system is a high-speed optical fiber ring bus tightly connected.This is because: First of all, We look at the implementation of a high-speed communications subsystem that can deliver up to 1 megabyte of large files in seconds, and secondly, the file subsystem can be thought of as back-end processor support in this system. The backend’s files can be accessed from the remote functional subsystem, and the ring bus thus designed can transfer data as fast as the I / O channels of the file subsystem without becoming “ Bottleneck ”Third,
