Using Link Fragmentation and Interleaving
.. Real-time streams usually consist of small packets, and jitter is caused
when the regularly timed transmission of these packets is interrupted by
the serialization delay of sending a large packet. Serialization delay is the
fundamental time it takes a packet to be sent out a serial interface.
.. Using a feature like LLQ or PQ can significantly reduce delays on realtime
traffic, but even with this enabled, the time a real-time packet may
have to wait for even one large packet to be transmitted could be large
enough to add jitter to the stream.
.. Link Fragmentation and Interleaving overcomes this by reducing the
maximum packet size of all packets over a serial link to a size small
enough that no single packet will significantly delay critical real-time data.
