Detailed Description

BB Frame container class.

Holds information of BB Frames for forward link scheduling.

SatBbFrameContainer implements own queues (container) for every used MODCODs. These MODCOD queues are used for non control packets (priority class different than 0).

For control messages (priority class 0) is used only one queue with most robust MODCOD.
