Abstract
A communication control method accomplishes minimum bandwidth guarantee and maximum bandwidth restriction and further allocates an extra-bandwidth in accordance with user's contact bandwidth. Fixed-length packets are once stored in corresponding partitions of a buffer in accordance with connection information contained in the packets and then transmits the packets from the storage sections in succession. Retrieval of a connection where the number of transmitted packets does not reach a lower-limit throughput and a packet to be transmitted exists in the corresponding partition is made with first priority, and retrieval is further made in order for a connection where the number of transmitted packets does not reach an intermediate throughput and a connection where the number of transmitted packets does not reach an upper-limit throughput. If the retrieval shows a hit connection, the packets are transmitted from the corresponding partition and one-time retrieval comes to an end.
