dDrops: Detecting silent packet drops on programmable data plane

, a packet-level telemetry based on programmable data plane to detect and retrieve details of silent packet drops immediately when they happen. has been implemented on both P4 hardware programmable switches (based on Intel Tofino ASIC) and BMv2. Extensive experiment results show that is able to detect and locate the silent packet drops within 5 ms (including detailed information of dropped packets), and reduce the memory consumption by up to 50%.
