Abstract
A scalable hub divided into a plurality of internal hubs. Each internal hub is connected to a subsequent internal hub in a loop topology. The connection point for each internal hub to the interhub loop is a port which either bypasses that internal hub, isolating the disconnected internal hub, or connects that internal hub to the interhub loop, such that data flows between that internal hub and the interhub loop. In addition the preferred embodiment provides graceful degradation when an internal hub connected to the interhub loop fails.
