14.11.1.2 Delay Control
The delay control mechanism in the MDM6000 is used to optimize for jitter introduced by the
encapsulation mechanism and to optimize the available bandwidth used.
MDM6000 >> Encapsulation >> Delay Control
Parameter Description
Optimized for ACM This is the default setting, it optimizes the bandwidth usage by delaying
BBFs until they are completely filled with traffic data prior to effectively
transmitting them. The encapsulation interval and packing time are
dynamically set to allow optimal BBF efficiency even in case of bursty
traffic. This approach leads to the highest filling levels off the BBFs and
hence the highest efficiency on the link. On the downside, it introduces
a slightly variable amount of delay and additional jitter when dealing with
low rate and bursty traffic. Use this mode for higher rate, continuous
(quasi non-bursty) traffic.
Optimize for jitter This mode is preferred for low speed links with bursty traffic and
applications that are jitter sensitive as it will automatically lower the
encapsulation interval and packing time. This mode might lead to a slight
reduction in link efficiency as the BBFs are sent out at a steady pace
whether they are completely filled or not. This non-optimal link filling
efficiency is not so important as the link's filling level is variable anyhow
when dealing with bursty traffic.
