Patent attributes
A packet processing device in which a receiving buffer free space notifying portion notifies a free space of a receiving buffer, an accumulation condition determining portion determines a size of a big packet based on the free space, and a reassembly buffer processor reassembles a plurality of receiving packets into a single big packet to be transmitted to the receiving buffer. A backward packet inclusive information reading circuit for detecting the free space based on information within a backward packet from the upper layer may be used as the receiving buffer free space notifying portion. Also, an application layer may be used as the upper layer so that the big packet is transmitted not through a buffer of a transport layer but directly to the receiving buffer.
