Claim Text:
1. A method, comprising: determining an initial path in a wireless deterministic network between a source and a destination through one or more intermediate nodes by one or more path computation engines that is not the source, the destination nor said one or more intermediate nodes, with the wireless deterministic network being a low power lossy network, with each of the source, the destination, and said one or more intermediate nodes being a low power lossy network node; establishing the initial path from the source and destination through said one or more intermediate nodes based on a set of predetermined timeslots; communicating packets over the initial path from the source and destination through said one or more intermediate nodes using the set of predetermined timeslots; informing at least one node of said one or more intermediate nodes of a required metric including a receiving timeslot for receiving a packet from a prior node in the initial path and a sending timeslot for sending the packet to a next node in the initial path; and locally, without contacting any of said one or more path computation engines, reconfiguring the initial path from the source to the destination to bypass at least one of said intermediate nodes creating a new path, wherein the new path communicates packets using the sending and receiving timeslots.
