- Abstract
IEEE 1394 is a network communications standard that has recently found its way into many complex system designs. The reason for this is the low cost of commercial components due to the extensive use of 1394 with personal computers. Additionally, the IEEE 1394b standard allows for cyclical redundancies within network topologies, making 1394b a good choice for fault-tolerant systems. Bus rates for 1394 are approaching 1Gbps (a vast improvement over the de-facto standard MIL-STD-1553’s 1Mbps) and there are plans to make 1394 components with bus rates up to 3200Mbps. Data rates such as these coupled with faster and more efficient processing power will enable Artificial Intelligence (AI) capabilities only previously dreamed of on complex space systems. However, there are challenges to making IEEE 1394 a deterministic networking protocol for hard-real-time systems. This paper addresses the challenges of integrating IEEE 1394 onto spacecraft and how IEEE 1394 will support functions like Integrated System Health Monitoring (ISHM). In particular we will address: 1) the issues that arise in ensuring deterministic behavior with IEEE 1394, 2) analyze some solutions outlined to these issues by organizations such as SAE, and 3) discuss how higher bandwidths enable capabilities like ISHM.
