Dear authors, all,

Thank you. With these fixes I think we can proceed with IRSG publication process.

Cheers,   Vincent and Marie-José

> Abstract:
>   This document is the product of the Coding for Efficient Network
>   Communications Research Group (NWCRG).  It conforms to the directions
>   found in the NWCRG taxonomy [RFC8406].  Thus, the scope of the
>   document is network coding as a linear combination of packets in and
>   above the network layer.  Physical and MAC layer coding are beyond
>   the scope of the document.  The draft focuses on a multi-gateway
>   satellite system and identifies the use-cases where network coding
>   provides significant performance improvements.  The objective is to
>   contribute to a larger deployment of network coding techniques in
>   SATCOM to complement already implemented loss recovery mechanisms.
>   The draft also identifies open research issues related to the
>   deployment of network coding in SATCOM systems.
