Communication device and communication control method using lower layer data transmission order control at upper layer

摘要

In a communication device using a communication protocol with data loss compensation functions provided at both an upper layer and a lower layer, a transmission order among packets to be transmitted is controlled at the lower layer, according to the transmission states of upper layer connections to which the packets belong, such that when there is at least one non-transmitted packet for each one of at least two different upper layer connections, at least two packets to be transmitted consecutively are belonging to different upper layer connections.
