This report is aimed at assessing some promising available or emerging commercial transmission technologies regarding their potential support of Military oriented Quality of Service M-QoS in the terrestrialsatellite Defence Core communications infrastructure. The chosen technologies are ATM, IP Integrated Services, IP Differentiated Services, MPLS and IPv6. The criteria of interest include the support of commercial QoS, prioritisationpreemption, graceful degradation of QoS, QoS interface with end-user applications, QoS modification, traffic engineering, scalability, bandwidth usage efficiency, and implementation in commercial as well as military networks. The report shows that none of the considered technologies can support all the criteria in isolation. However, a combination of IPv4IPv6, Differentiated Services augmented by bandwidth brokerage, MPLS and in some cases ATM is proposed in the report as a good candidate to build the future M-QoS capable Defence Core. More research is required to fully assess the applicability of the proposed combination to achieve M-QoS.
