System Testing Techniques for Computer Networks,
Abstract
The trend in real-time systems is to use distributed processors operating asynchronously in networks. Testing a complex system of this nature becomes a major problem. System testing measures system performance to see if it needs prescribed standards. Testing is broken into three areas: hardware, processing logic, and data throughput. Methods of testing each area are described. These include input/output tests, memory tests, functional tests, system statistics, timing, stacks, and error messages. The importance of on-line testing is discussed. The report proposes implementation or testing schemes in hardware as much as possible, even though this will affect the requirements of the computers to be used in the system. A typical implementation of testing for one system is described, along with methods of keeping the testing portion system simple. Examples from the San Francisco Experimental Vessel Traffic System are discussed. (Author)
