![]() This concept paper outlines a project for trying to solve the bulk of these problems in a comprehensive fashion. Furthermore, different vendors install different sets of improvements, so there is often little uniformity among network performance capabilities among vendor software. Part of the problem has been a lack of agreement among network researchers regarding comprehensive solutions, and part of the problem has been the traditional reluctance of operating system and other commercial software vendors to make network performance improvements in a timely fashion. The chief difficulty has been the failure of the market to address performance issues in a significant way. ![]() ![]() The solutions to many of the technical problems are well understood, and prototype implementations exist in many cases. Such network performance problems are mostly caused by poorly implemented and poorly designed commercial host-software in Layers 3 through 7 of the OSI Reference Model. This result is not unique to just FTP similarly poor results are seen with almost all other out-of-the-box (and much custom) networking software. When a typical academic researcher attempts to transfer large datasets using conventional vendor-supplied FTP-based programs on high-performance LAN or WAN networks that are purported to provide 100-Mbps (megabits/second) performance, the researcher is often lucky to see 10-Mbps actual transfer rates.
