http://tools.ietf.org/id/draft-do-roll-p2p-backup-01.txt recently expired. Abstract In this draft, a backup path setup mechanism is proposed for the P2P-RPL protocol in Low Power and Lossy Networks (LLNs). This mechanism allows sensor nodes to send packets over the backup path without rediscovering the p2p path in case of path failure, thus improving the reliability of p2p transmission. ==== I read the document prior to it expiring, and I can see how this could be useful in many networks. The document claims: Nodes utilize the interactive path as alternative to quickly recover from failure to send packets to the destination instead of recreating the path. It would be interesting to have feedback from deployments about how valuable having an alternative path would be. I did not yet understand how the backup nodes are used. Can this protocol be incrementally deployed? Is there interest in further discussion of this document? -- Michael Richardson <mcr+IETF@sandelman.ca>, Sandelman Software Works IETF ROLL WG co-chair. http://datatracker.ietf.org/wg/roll/charter/
