Abstract A general network is studied in which messages are relayed from multiple sources to multiple destinations according to a certain hierarchical order. The framework of \textit{flow decomposition} is used to show the class of regular-order decode-forward index-coding schemes is computable. A shifting algorithm finds encoding/decoding schemes in P($|{\cal N}|$)EXP($|{\cal S}|$) time that achieve desired rate-vectors, where ${\cal N}$ is the set of nodes and ${\cal S}\subseteq{\cal N}$ is the subset of source nodes in the channel.
