We propose DISCO - a lightweight approach to flow monitoring in the data plane. The idea is to disaggregate the computation of a single (logically) centralized sketch into multiple small "sketch fragments" that are distributed across the flows' paths. This allows use less resources at switches without trading on telemetry capabilities.
