Abstract: One example embodiment provides a method and system where a node in an IPv6 utility network communicates with an IPv6 destination node through and IPv4 network. IPv6 utility nodes are reachable through at least one access point. IPv6 packets to be transmitted between an IPv6 access point and an IPv6 destination node through a IPv4 communications network are encapsulated in IPv4 packets for transmission through the IPv4 communications network. Packets received after transmission through the IPv4 communications network at the destination node are extracted to retrieve the IPv6 packet.

Abstract: One embodiment of the present disclosure sets forth a technique for convergence and automatic disabling of access points in a wireless mesh network. Specifically, an access point within a wireless mesh network computes one or more network metrics to determine whether the metrics are unfavorable or favorable. If the network metrics are favorable, then the access point disables the access point's network connection. An access point turns the network connection back on based on whether a routing was lost for at least a preset amount of time, utilization of one or more neighboring access points is above a preset value, or one or more network metrics have degraded by a certain percentage value. One advantage of this approach is that cost savings may be achieved when the number of access points dynamically changes to accommodate varying communications conditions.

Abstract: One example embodiment provides a method and system where a node in a utility network registers with one or more access point devices associated with one or more local area utility networks. The utility node generates a unique network address using a network address prefix of a network address associated with the access point device. The utility node registers with a DNS server. Messages sent to the utility node are routed through the access point corresponding to the received prefix used to generate the unique network address for the utility node. The network address for the utility node and access point may be IPv6 addresses and the network address prefix may be an IPv6 prefix, or may be an IPv4 address.
