SpaceMoE: Realizing Distributed Mixture-of-Experts Inference over Space Networks

Huiling Yang, Kaibin Huang, Khaled B. Letaief, Min Sheng, Zhanwei Wang

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Experiments over a thousand-satellite constellation show that Space-XNet achieves at least a threefold latency reduction compared with conventional random and ablation-based placement strategies.

C2weakest assumption

The assumption that autoregressive inference follows a ring-like communication pattern that can be directly exploited by partitioning the constellation into ring subnets, and that the intra-layer optimization based on activation probabilities and expected latency fully captures real performance without hidden costs such as accuracy degradation or unmodeled interference.

C3one line summary

Space-XNet partitions satellite constellations into ring subnets for MoE layers and maps high-activation experts to low-latency satellites, yielding at least 3x lower inference latency than random or ablation placements in 1000-satellite simulations.
