 The following group types are collected in an [`SRT_GROUP_TYPE`](#SRT_GROUP_TYPE) enum:
 
-* `SRT_GTYPE_BROADCAST`: broadcast type, all links are actively used at once
-* `SRT_GTYPE_BACKUP`: backup type, idle links take over connection on disturbance
-* `SRT_GTYPE_BALANCING`: balancing type, share bandwidth usage between links
