Summary

The architecture of new networks is mostly based on a heterogeneous structure. One of the key issues of such networks is the integration of various network technologies into one Internet protocol (IP) environment.

In this regard, there is a need to use a gateway (Recommendation ITU-T Y.4000/Y.2060) which may be located between different technological segments of the network. The gateway will be used as an intermediary point which transfers messages from one network segment to another. In general, this gateway may be used as a point of traffic aggregation among Internet of things (IoT) devices to be used to interconnect different segments of a network.

This Recommendation describes the testing methodology of the heterogeneous network gateway which is to be used for communication among IoT devices. The tests will include the following, but not limited to:

•            checking the gateway to verify stress load (benchmarking)

•            checking the gateway to determine the possibility for  the  transmission of various types and sizes of frames and (or) packages;

•            verifying joint conversions from different protocols and multiple interfaces;

•            checking the gateway operation settings (CPU, RAM, etc.);and•    checking the network parameters (delay, data loss, etc.).
