Stream shaping in AVB networks

Embodiments are disclosed for a device for determining a number of sample blocks to include in a packet. In some embodiments, a device comprises a communication interface communicatively connectable to another device and configured to transmit data, a processor, and a storage device that stores instructions executable by the processor to determine a total sample size of samples stored in a transmission buffer. The instructions are further executable to calculate a bandwidth credit based on a reserved bandwidth and an elapsed time since a last sent packet, determine a number of sample blocks to include in a packet based on the total sample size and the bandwidth credit, and generate a packet including the determined number of sample blocks.
