Abstract: Highlights•Designed a distributed streaming system called SAND for high-speed network analytics.•Implemented upstream backup and checkpointing to provide failure recovery for SAND.•Proposed a checkpointing protocol that guarantees strong consistency after recovery.•Implemented several real-time network analytics applications on SAND.•Used traces collected from commercial cellular networks to evaluate our system.
