I don't know if this is done though. I cannot find anything about Ack compression in LTE. (The PDCP protocol does header compression, so that's the place I'm looking.) -- Juliusz _______________________________________________ Bloat mailing list Bloat@lists.bufferbloat.net https://lists.bufferbloat.net/listinfo/bloat
