• Description:
• Tenders are invited for Secure and Application-Selective Multicasting in Multi-Layer Satellite Constellation Networks The objectives of the activity are the design, development and demonstration of secure multicasting, routing and secure group management protocols in satellite constellation networks involving thousands of NonGEO and GEO satellites. Targeted improvements: Increased user traffic plane efficiency (30%) and allow for a more secure user traffic plane. Description: Synchronisation of Content Delivery Network (CDN) edges, data centres, blockchain ledgers are examples of some use cases for multicasting in satellite networks. Multicasting via GEO satellite systems may also be invaluable for efficient batch configuration and software update of NonGEO satellites in the network. Multi-layer satellite constellation networks with GEO and NonGEO satellites allow to selectively use GEO satellites for unicast/multicast connectivity within the network. The large coverage provided by GEO satellites in addition allows to decongestion inter-satellite link network among NonGEO satellites. However, in order to leverage multi-orbit satellite systems in these scenarios, application-selective unicast/multicast routing protocols, traffic engineering algorithms, and secure multicast group management protocols must be developed and demonstrated in such networks. Traffic engineering and route selection are particularly hard in the presence of end-to-end aggregate flows where application types and QoS of individual streams are obfuscated due to end-to-end encryption. The proposed activity shall investigate solutions in collaboration with relevant cybersecurity partners. There is already a rich literature proposing solutions for these problems for terrestrial networks. Adaptations and optimisations of these solutions are still missing for multi-layer satellite constellation networks where thousands of satellites are involved. Such large constellations pose specific challenges for protocol scalability and efficiency. The key engineering challenges are the design of application-selective unicast/multicast routing protocols with intelligent traffic engineering functions at edge and intermediate nodes, and the design of multicast group and key management protocols. The work shall design solutions for these problems, evaluate their performances in software simulators, and validate them in demonstration testbeds that are representative of the HW platforms available on board the satellites Price Range 500 KEURO
