This paper investigates the extent to which the IEEE 11073 SDC standard family loads a communication network. An SDC provider/consumer based on the SDCLib/J from SurgiTAIX AG was implemented as a test environment and several different test scenarios were run in order to gather data sets for different use cases. The analysis of the thus acquired measurements shows a linear, predictable growth in network utilization for almost all combinations of active metrics and value update rates. In the case of very high metric update rates, a stagnation of network utilization can be observed. This behaviour can be explained by the use's implementation and an unfavourable test setup. Overall, the network load generated by SDC is justifiable.
