Detailed Description

SatFwdLinkScheduler schedules BB frames for forward link.

In every GW MAC is assigned own instance of the SatFwdLinkScheduler. To handle BB frames and maintain queues for the them, it utilizes BB frame container given as attribute.

SatFwdLinkScheduler communicated through callback functions to request scheduling objects and notifying TX opportunities.

   GW MAC requests frames from scheduler through method GetNextFrame.
