Abstract: Systems and methods for detecting device failures in a network having nodes coupled to a central controller, in which a first of the nodes communicates with the central controller via a second of the nodes. When the second node determines that the first node has not transmitted a predetermined number of messages over a predefined number of time periods, the second node provides a failure alert to the central controller. The central controller records a failure alert received from the second node in a log. Based on a set of failure alerts received from a number of nodes recorded in the log, the central controller determines whether the first node has failed.
Abstract translation: 用于检测具有耦合到中央控制器的节点的网络中的设备故障的系统和方法，其中第一节点经由第二节点与中央控制器通信。 当第二节点确定第一节点在预定数量的时间段内尚未发送预定数量的消息时，第二节点向中央控制器提供故障警报。 中央控制器记录从日志中的第二个节点接收到的故障警报。 基于从日志中记录的多个节点接收的一组故障警报，中央控制器确定第一节点是否已经失败。

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 example embodiment provides a method and system where a node in a utility network receives a block of IPv6 network addresses from an access point in the utility network. The utility node allocates an IP network address from the block of IPv6 network addresses received from the access point to an in-premise device which communicates to the utility node over an in-premise network which is not IP based. The utility node proxies the allocated IP address to the utility network, allowing other nodes on the utility network to address and communicate with the in-premise device.

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.
