Objective: To explore, identify technology issues and propose solutions extending current standards in order to consolidate a set of protocols that will enable seamless deployment of secure dynamic multicast based interactive applications over next generation of multi-spot beam satellite broadband systems. Validation of the protocol set via simulations for a subset of secure multicast applications is also envisaged.
Targeted Improvements: Enable new multicast based secure interactive applications to be deployed in next generation of multi-spot beam satellite broadband systems. Improvement of 30% to 40% in performance of current secure multicast applications can be expected based on most efficient over satellite secure key management and secure dynamic multicast implementation instead of multicast traffic encapsulation on IPsec tunnels.
The volume of multicast traffic has been growing primarily based on the emergence of video-based applications. Examples can be found in IPTV and in dual use scenarios such as secure collaborative working groups, secure remote medical assistance and distant learning. Next generation of multi-spot beam satellite systems are considered as the underlying transport system. IETF MSEC working group IPsec based multicast extensions and MPLS/BGP protocols together with the proper encrypting mechanisms to conform a multicast VPN suitable to be deployed over multi-spot beam satellite systems represent the starting point of the activity.
Secure network dynamic multicast protocols are essential in enabling multimedia systems and applications in scope. In order to define a set of suitable protocols supported by a multi-spot beam system it is necessary to analyse and validate the proposed solutions to the issues inherent to the system and typical satellite link impairments and characteristics. Examples are bandwidth constraints and channel fading together with the fact that the solution has to scale to a large population of users in different spot-beams coverage areas. Efficient secure key management represents a challenge on the above-defined context. In addition, group route management, service mobility, appropriated encryption mechanisms for MPLS VPN schemes, maturity of MSEC and IPv4 and IPv6 deployment differences are also targeted.
A study task to review current status in standardisation on secure multicast focusing on satellite systems is envisaged. This will form the bases for further identification of protocol modifications needs and technology gaps. Subsequent tasks will focus on the issues identification and proposed solutions. In addition suitable simulation platform at IP/Network level should be defined together with a simulation test campaign based on the scenarios of interest to validate and demonstrate the proposed protocol set. Finally, a technical report with recommendations to the standardisation bodies will be generated.
