  • Patent number: 9992117
    Abstract: A network apparatus includes a memory and one or more processors. The memory stores instructions. The one or more processors are configured to execute the instructions to mark a traffic that exceeds a predetermined rate limit. The one or more processors are also configured to execute the instructions to measure an amount of the marked traffic by using one or more filters to detect information written in a data packet by the one or more processors. The one or more processors are further configured to execute the instructions to output the measured traffic amount in a period determined based on an expected time duration of an abnormal traffic. The abnormal traffic is a detection target of the network apparatus.

  • Patent number: 5923875
    Abstract: A load judging means 21 judges whether or not to receive the job transferred from the job transferring unit 1 based on the calculated result of the load of the computer wherein the load judging means 21 itself sits in. A backlog controlling means 23 generates a backlog corresponding to the job which was judged as unreceivable, controls to erase and change the backlog, and requests rescheduling the backlog when the backlog was generated or erased. A job queuing means 27 requests rescheduling the backlog when there are any changes in the states of jobs under process or unprocessed. A job transfer requesting means 26 issues a request for transferring the object job when the backlog scheduling means 25 judges the object job as receivable.
