Abstract:

Telemetry is a new generation network monitoring technology, which could reduce the loads of probes by setting the frequency of probes and target of monitoring to switches. In-band Network Telemetry (INT) is a technique of telemetry which enables precise monitoring without reducing the traffic rate. It embeds the telemetry headers including information and instructions of INT processes, then INT enabled switches respond to the instructions in hardware-level. However, if all INT compatible switches simply respond the instruction, it will cause explosive growth of amount of collecting information and makes the load of analysis much heavier. In this paper, we discuss about design and implementation of selective telemetry mechanism which is fully controllable from edge-side. Using the proposed mechanism, administrators can select the switches which is required to be analyzed, then reduce the cost of monitoring. In our proposed mechanism, types of information and list of target switches are marked in the INT header, and only the target INT-enabled switches process the INT operation according to the instruction in the INT header of each packet. Our proposed approach will increase the controllability of telemetry and enhance the flexibility of management of large-scale network.
