Abstract: A fault tolerant distributed computing system includes a communication link and a plurality of nodes in electronic communication with one another by the communication link. Each node executes at least one node-specific application, includes a standby database that stores a standby copy corresponding to one of the node-specific applications executed by one of the remaining nodes that are part of the distributed computing system, and includes a spare computational capacity sufficient to execute at least one standby copy of one of the node-specific applications stored in the standby database. In response to determining a specific node is non-operational, the remaining nodes execute all the standby copies of the one or more node-specific applications that were previously executed by the specific node that is now non-operational.

Abstract: A distributed computing system includes one or more computing devices and one or more communication links in electronic communication with one another. Each communication link includes one or more nodes and a port switch. The one or more nodes are in electronic communication with one another by a communication link and the communication link is connected to the distributed computing system by the port switch. The port switch executes instructions to identify an online unique stream profile for a specific stream and determine an expected unique stream profile deviation during a specified interval of time. The port switch determines a difference between an offline unique stream profile and the online unique stream profile, compares an absolute value of the difference with the expected unique stream profile deviation, and in response to determining the difference is greater than the expected unique stream profile deviation, determines a fault has occurred.
