PACKET TRANSPORT APPARATUS, PACKET TRANSPORT SYSTEM AND PACKET TRANSPORT METHOD

摘要

[Problem] In a case where a plurality of packets are compiled for transmission to a network, the length of data to be continuously transmitted to each of a plurality of destinations is increased and hence the time interval in which the packet(s) addressed to each destination gets a transmission opportunity is increased, with the result that the packet delay is disadvantageously increased. [Solution] A packet extraction unit (22 of FIG. 2) extracts a plurality of packets as a whole from a packet compilation queue (21 of FIG. 2) that sorts, according to destinations, and stores packets. A limited number of packets to be extracted as a whole at this time is given in accordance with a maximum packet compilation number defined by a maximum compilation number calculation unit (29 of FIG. 2) on the basis of a band increase and a delay increase due to a packet compilation.

1. A packet transmission apparatus comprising:
a storage unit which sorts and stores packets in accordance with each destination; an extraction unit which extracts a plurality of packets stored in the storage means for each destination by one-time operation; and a maximum packet number setting unit which sets a maximum number of packets to be extracted by the extraction unit by one-time operation, wherein the maximum packet number setting unit sets the maximum number of packets in such a manner that an integrated gain representing an increase in band by aggregation of extracted packets, and a transmission delay by the packet aggregation is equal to or larger than a predetermined value.
