Packet scheduling modes
- Normal (stream interleaved mode) – standard scheduling mode, precise rates, minor variation in packet inter-frame gap.
- Strict Uniform – new scheduling mode, with 100% uniform packet inter-frame gap, minor deviation from configured rates.
- Sequential packet scheduling (sequential stream scheduling). Streams are scheduled continuously in sequential order, with configurable number of packets per stream.
- Burst. Packets in a stream are organized in bursts. Bursts from active streams form a burst group. The user specifies time from start of one burst group till start of next burst group.
