This document proposes a B2B Gateway managed file transfer service to replace UT's existing unmanaged file transfer service. The gateway would support both internal and external file transfers in a fault-tolerant manner using Stonebranch software. It describes problems with the current approach, assumptions that did not match reality, consumer needs and personas. Key features are managed internal file transfers with familiar protocols and a phased approach is outlined, starting with internal transfers and later adding external integrations and additional protocols. Success is defined in terms of new consumers, task reliability and usage metrics.
