  • Patent number: 5968130
    Abstract: A location information management table 14 stores information on the location of the host both at present and prior to the movement. The host is movable based on the transmission address contained in the frame transmitted therefrom. The frame addressed to the host is transferred to the segment presently connected and to the segment that has been previously connected based on the table 14. Even though the host locates halfway among a plurality of segments, stable communication can be realized. When the host moves away from other segment toward the center of one segment, the frame is transferred to one segment at a time when the timer terminates its counting operation, thus deleting unnecessary traffic.

  • Patent number: 5966730
    Abstract: A backup system is operated in accordance with a server or intelligent storage data controller containing a pre-written script governing a backup protocol. This script designates the possible source of data for backup that could become visible on the network and the possible storage sets that may be available in the storage repository. Preferably, the script also contains a timetable for when the script should be active, and wrap up interval of time for intelligently terminating a particular backup operation. In operation, the total number of accessible data sources (usually computers) and the total number of storage media destinations (for example available tapes mounted in tape drives) are generated to list possible source to storage paths. Utilizing the script, the possible source to storage paths are prioritized with the least recently backed up source as dated by the available media having first priority for backup.

  • Patent number: 5958017
    Abstract: A congestion control mechanism for a node of a modular computer network system. The mechanism includes registers for maintaining the number of undelivered requests and unanswered requests for the node and registers for the maximum number of such undelivered requests and unanswered requests. The mechanism regulates congestion on the network by throttling back or ratcheting up the allowed number of undelivered requests and unanswered requests based upon the level of busy and non-busy results of such requests and answers. Congestion is also alleviated by the implementation of a set of large and small send and receive buffers. These buffers are configurably partitioned among virtual I/O channels. Each request virtual I/O channel may utilitize congestion control.
