Stroboscope: Declarative Network Monitoring on a Budget
summary
System instructs routers to mirror millisecond-long bursts so collectors get packet-level snapshots; it calls this traffic slicing and uses GRE-like encapsulation already on commodity routers. Algorithms pick a minimal set of mirroring locations with provable correctness, place surrounding cuts for confined queries, and schedule activations to meet a user budget; routers flip mirroring in about 22 ms slices, schedules compute in seconds for large topologies, never exceed budget by more than one timeslot.
