저궤도(LEO) 환경을 위한 우주 인터넷 교환소(Space-IX) 아키텍처 설계와 구현

Technical analysis and engineering reference.

1. The Ground Trombone Inefficiency in Space Telecoms

Currently, if a customer using Satellite Constellation A wants to communicate with a customer on Satellite Constellation B, the data must travel down to Constellation A's ground station, pass through a terrestrial telecom carrier, enter a physical terrestrial Internet Exchange Point (like DE-CIX or AMS-IX), travel to Constellation B's teleport, and uplink back into space. This round-about trip introduces 150 to 300 milliseconds of unnecessary latency and massive transit costs.

2. The Space-IX Solution: Pure In-Orbit Peering

XhaulNetwork creates dedicated peering satellites hosting non-blocking optical cross-connects: - Multi-head optical steerable transceivers locking onto subscriber satellites from different operators simultaneously. - Route servers executing standard BGP-4 routing policy engines. - Traffic flows between Constellation A and Constellation B directly through the vacuum of space, cutting inter-operator latency to sub-20 milliseconds.

3. Commercial and Regulatory Frameworks

Participating operators sign bilateral or multilateral peering agreements modeled after Euro-IX templates, establishing credit-free settlement peering while preserving user privacy and operational separation.
