    摘要: An exemplary method of communicating with a safety device includes obtaining a key from the safety device that is useable for only a single communication session with the safety device. A plurality of messages are sent to the safety device during the single communication session. Each of the plurality of messages includes the obtained key, an identifier of the source of the message, an identifier of the safety device, a sequence number indicating how many of the plurality of messages preceded the message during the communication session, a command for the safety device, and at least one cyclic redundancy code (CRC) based on content of the message. A next one of the plurality of messages is sent only after confirming that the safety device has accepted a most recently sent one of the plurality of messages.

    摘要: In one embodiment, the present invention is a method and apparatus for layering agents in a distributed computing system. In one embodiment, a system for monitoring and controlling a distributed computer network including a plurality of components (e.g., devices) includes a plurality of cells, each of the cells being deployed to directly monitor and control one of the components of the network. The system also includes at least one federation, where the federation is made up of cells that cooperate to solve common problems, and at least one supercell, where the supercell provides supplemental decision making capabilities to the cells and federations. In this manner, problems detected by a cell that cannot be resolved by the cell may be forwarded to the cell's associated federations or supercells for resolution.
