They all face the same challenge: 𝗛𝗼𝘄 𝗱𝗼 𝘆𝗼𝘂 𝗺𝗼𝘃𝗲 𝗺𝗮𝘀𝘀𝗶𝘃𝗲 𝗮𝗺𝗼𝘂𝗻𝘁𝘀 𝗼𝗳 𝗱𝗮𝘁𝗮 𝗮𝘀 𝗾𝘂𝗶𝗰𝗸𝗹𝘆 𝗮𝘀 𝗽𝗼𝘀𝘀𝗶𝗯𝗹𝗲 𝘁𝗵𝗿𝗼𝘂𝗴𝗵 𝗻𝗲𝘁𝘄𝗼𝗿𝗸𝘀 𝘁𝗵𝗮𝘁 𝗮𝗿𝗲 𝗰𝗼𝗻𝘀𝘁𝗮𝗻𝘁𝗹𝘆 𝗰𝗵𝗮𝗻𝗴𝗶𝗻𝗴?

A new study led by FCP researchers from the Singapore University of Technology and Design (SUTD) introduces 𝗢𝗣𝗦𝗦 (𝗢𝗻𝗲-𝗣𝗮𝘀𝘀 & 𝗦𝗺𝗮𝗿𝘁-𝗦𝗲𝗮𝗿𝗰𝗵), a novel algorithm designed to dramatically speed up data delivery in time-varying networks.

Satellite networks such as Starlink are made up of thousands of satellites moving rapidly around the Earth. Connections between satellites appear and disappear continuously, making efficient data routing a highly complex challenge. Instead of repeatedly recalculating routes from scratch, OPSS intelligently reuses previous computations and focuses only on the most promising network paths.

The result?
• Up to 38× faster than current state-of-the-art approaches.
• Solves large-scale satellite routing problems in just seconds.
• Demonstrates strong scalability on real-world constellation models.

Beyond satellite communications, the ideas behind OPSS could help optimise data movement across future 6G systems, cloud infrastructures, and other large-scale dynamic networks.

This research has been accepted for publication in 𝗜𝗘𝗘𝗘 𝗧𝗿𝗮𝗻𝘀𝗮𝗰𝘁𝗶𝗼𝗻𝘀 𝗼𝗻 𝗠𝗼𝗯𝗶𝗹𝗲 𝗖𝗼𝗺𝗽𝘂𝘁𝗶𝗻𝗴, one of the leading journals in computer and mobile networking research.

Congratulations to our colleagues on this excellent contribution to advancing efficient networking for our increasingly connected world!
