Abstract:
1. A method of allocating transmission resources for transmitting, in a communications network, a data stream from an intermediate device to a destination device, the data stream including a plurality of application data packets, the application data packets including application time-stamp information indicating a frequency of generating the application data packets, and the application data packets being transmitted from a source device to the intermediate device encapsulated in a plurality of transport data packets according to a communications protocol, wherein the intermediate device performs steps of: receiving the transport data packets according to the communications protocol; obtaining the application time-stamp information from the application data packets included in the transport data packets received; determining an application bit rate from the application time-stamp information obtained and information indicating a quantity of data of the data stream received by the intermediate device; determining whether the data stream is a constant bit rate data stream or a variable rate data stream, based on determined application bit rate information; determining a value of bandwidth, based on the determined application bit rate and on whether the data stream is determined to be a constant bit rate data stream or variable rate data stream; and allocating the determined value of bandwidth for transmitting the data stream from the intermediate device to the destination device.
