Boost.Signals is an excellent building block for dataflow networks, as it provides support for all of the essential elements - data transport through parameters and return values, combining return values from multiple signal calls, component invocation, and reconfigurability through connection and disconnection.

The Signal Network library uses Boost.Signals as the data transport mechanism in dataflow networks. In addition, it provides two major elements that facilitate the building of large signals-based dataflow networks:
