The aggregators allow the aggregation of phasors from multiple PMUs (with the same reporting rate) into a single custom
data set to optimize bandwidth when streaming.

5.5.8.6 Configuration example: CFG-2 based configuration (using IEC 61850-90-5)
The L90 is expected to send the CFG-2 file (IEEE C37.118 config. file) upon request from the upstream synchrophasor
devices (for example, P30) without stopping R-SV multicasting, as shown in the following figure. The primary domain
controller (PDC) does not need to use a stop/start data stream command if the UR protocol is set to IEC 61850-90-5 prior to
requesting the configuration via CFG-2 (IEEE C37.118 config. file). The CFG-2 request from the P30 can be on TCP/IP or
UDP/IP, however, R-SV data streaming is only UDP multicasts (not TCP).
