Mesh network addressing

摘要

In embodiments of mesh network addressing, a router registers an address for an end device and assigns a child identifier to the end device. The router encodes an endpoint identifier of the end device, and a router identifier of the router into an Endpoint Identifier, which the router incorporates into a Routing Locator (RLOC) for the end device. The router responds to address queries and receives data packets on behalf of the end device. The router stores the data packets for the end device until the router can forward the data packets to the end device.

主权项

1. A method of managing end device addresses in a mesh network by a parent router device, the method comprising:
attaching to a child end device in response to the child end device exiting a sleep mode and powering up a mesh network interface of the child end device, the child end device being configured to re-enter the sleep mode and power down the mesh network interface of the child end device at some point in time after said attaching; receiving, from the attached child end device, a child identifier; encoding, by the parent router device on behalf of the child end device, an Interface Identifier (IID), based on the received child identifier of the child end device and a router identifier of the parent router device, into a Routing Locator (RLOC) for the child end device; receiving an address query for the child end device at the parent router device; responding to the address query on behalf of the child end device with the RLOC associated with the child end device; receiving data packets for the child end device, the data packets being stored at the parent router device when the child end device is operative in the sleep mode; and forwarding the stored data packets to the child end device responsive to the child end device exiting the sleep mode.
