摘要： A communication device includes a buffer that stores transmission packets. The communication device monitors a free space of the layer 2 transmission buffer. The communication device changes a first window size that is notified from another communication device, to a second window size, based on the free space, and controls an inflow of the transmission packets to the layer 2 transmission buffer, in accordance with the second window size. By providing above-mentioned communication device and a packet control method, a reduction in a throughput caused by overflow in layer 2 transmission buffer is avoided.

摘要： A method of an abnormality detection, the method including: calculating an occurrence degree of a packet loss in each of multiple queues on the basis of a first time period in which each of multiple processes that receives a packet is in a waiting state and an arrival frequency of a packet in each of the multiple queues that stores the packets received by the multiple processes; distributing the number of packet losses occurred in a communication device that includes the multiple queues to each of the multiple queues on the basis of the calculated occurrence degree; and determining whether or not an abnormality occurs in each of the multiple processes on the basis of a correspondence relationship between an operation state of each process and the number of packet losses distributed to the queue that corresponds to each process among the multiple queues for each of the multiple processes.
