Burst size and density can be specified. Uniform and bursty bandwidth profile streams can be interleaved
-
Field modifiers
16-bit header field modifiers with inc, dec, or random mode. Each modifier has configurable bit-mask, repetition, min, max, and step parameters. 5 modifiers per stream.

Pause Frames
Responds to incoming pause PFC (Priority-based Flow Control) frames
-
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 per 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.
