Abstract
This work investigates the problem of conveying discrete memoryless sources over general networks with specified lossless (vanishing error probability) and/or lossy (average per-symbol distortion) reconstruction demands. It presents two different sufficient conditions under which an edge carrying zerorate messages is not crucial for the conveyance of the sources, i.e., the demands can be met even when the zero-rate edge is deleted and the rates on other edges are kept unchanged.
