SUMMARY Digital Video Broadcasting, Return Channel via Satellite 2 (DVB‐RCS2) is the second generation of DVB‐RCS communication specification for the return link in broadband interactive geostationary satellite networks. The focus of this paper is the user uplink access mechanism in DVB‐RCS2. The first part of the paper provides a brief description of DVB‐RCS2 user uplink access, with emphasis on improvements with respect to the first generation of the standard. One of these improvements in DVB‐RCS2 is the support for random access (RA) for user traffic. The second part of the paper further delves into the RA load control problem and proposes an analytical model for the DVB‐RCS2 RA load control algorithm followed by performance assessment via numerical computations and simulations.
