Abstract:
1. A communication apparatus configured to transmit data by configuring a plurality of virtual communication pathways in a physical communication pathway established with another communication apparatus, the communication apparatus comprising: a configuration unit that configures, for each of one or more virtual communication pathways included in the plurality of virtual communication pathways, option information for controlling an order of priority of transmitting stream data included in a data stream passing through the each virtual communication pathway, the option information including a stream number identifying the data stream in association with a first extension time indicating a time period for which transmission of the stream data is to be delayed; a first storage unit that stores the configured option information in association with the each virtual communication pathway; a second storage unit that stores the stream data, based on the configured option information; and a transmission processing unit that transmits the stream data to the another communication apparatus via the each virtual communication pathway, by controlling transmission timing of the stream data based on the first extension time included in the option information configured for the each virtual communication pathway, wherein the option information further includes signal identification information identifying a type of signal included in the stream data, in association with a second extension time indicating a time period for which transmission of the type of signal is to be delayed; and the transmission timing of each type of signal included in the stream data is controlled based on the second extension time associated with the each type of signal so that the different types of signals included in the stream data are transmitted to the another communication apparatus via the each virtual communication pathway at the respective different transmission timings in an order of priorities of the different types of signals.
