On the QoS for Satellite IP networks: a Follow-Up

This paper is adding recent trends and follow-ups on a previous overview on QoS for Satellite IP networks [1]. QoS classes defined by QoS functions and QoS parameters of the satellite network components can be mapped with IP QoS from the bottom to the top level. IP Multimedia System - IMS is considered as the core of the Next Generation Networks (NGN), the process of satellite access to IMS, including the transmission delay has been simulated [14]. A new QoS architecture that introduces optimization paths between layers and supplies advanced support for end-to-end QoS in IP satellite systems is analyzed [15]. A new software-defined architecture for next-generation satellite networks called SoftSpace [16] exploits concepts like network virtualization and software-defined radio in order to ease embedding of new services, apps or satellite communications technologies. A fuzzy satellite routing strategy for Non-Geo-stationary Earth Orbit satellite IP networks in order to meet multiple classes QoS requirements is being highlighted [17]. Design of a new algorithm for Radio Resource Management (RRM) with the purpose of increasing efficiency in multicast multimedia content transmission management over a satellite network is presented [18].
