[edit] Self Repairable


Spare Net for Elastic Interface Bus from US patent application 20080082878[2]
Self repairable elastic interface buses have recently been invented by IBM. IBM has filed a patent application on these buses which is undergoing peer review on Peer to Patent. The public commentary period closed on July 24, 2008.[2] The IBM invention provides a spare net which the system switches to in the event that an alternate net doesn't function.
