Abstract

A networkable device-to-networkable device communication method in Internet Protocol version 6 (IPv6). Embodiments include auto-configuration of IPv6 address and automatic commencement of communication among Fire Panels and other types of wired or wireless networkable devices. Each networkable device obtains its IPv6 address in a number of ways including from the first or any particular networkable device in a network. A designated networkable device instills IPv6 address to its neighboring networkable device, and subsequently the neighboring networkable device instills IPv6 address to its neighboring networkable device dynamically. Embedded Gateways are created dynamically in the network. Each networkable device uses its and its neighboring networkable devices' Embedded Gateways in order to transmit and receive IPv6 multicast, anycast or unicast packets. Embodiments obviate the need to use conventional Ethernet network backbone, networking and routing devices like switch or router, or manual configuration.

Claims9

Dependent claims

A method for configuring network configurable devices that are directly connected with each other in a network, the method comprising:

creating, using one of the network configurable devices, a lower 64-bit IPv6 address using Stateless Address Auto-configuration based on an Ethernet address of the one network configurable device:
creating, using the one network configurable device, an upper 64-bit IPv6 address:
storing the created upper 64-bit IPv6 address in a cache of the one network configurable device;
instilling, the created upper 64-bit IPv6 address into a cache of a neighboring one of the network configurable devices;
creating, using a lower 64-bit IPv6 address of the neighboring network configurable device, a link-local gateway of the neighboring network configurable device;
keeping the link-local gateway in an embedded gateway table of the neighboring network configurable device;
creating, using the lower 64-bit IPv6 address and the instilled upper 64-bit IPv6 address, a 128-bit embedded gateway of the neighboring network configurable device;
keeping the 128-bit embedded gateway of the neighboring network configurable device in the embedded gateway table of the neighboring network configurable device;
transmitting the presence of the link-local embedded gateway and 128-bit embedded gateway of the neighboring network configurable device to the one network configurable device;
and
communicating, using an embedded gateway table of the one network configurable device and the embedded gateway table of the neighboring network configurable device, between the network configurable devices.
