Patent number: 8189577Abstract: Methods and systems for providing a network and routing protocol for utility services are disclosed. A method includes discovering a utility network. Neighboring nodes are discovered and the node listens for advertised routes for networks from the neighbors. The node is then registered with one or more utility networks, receiving a unique address for each network registration. Each upstream node can independently make forwarding decisions on both upstream and downstream packets, i.e., choose the next hop according to the best information available to it. The node can sense transient link problems, outage problems and traffic characteristics. Information is used to find the best route out of and within each network. Each network node maintains multi-egress, multi-ingress network routing options both for itself and the node(s) associated with it. The node is capable of several route maintenance functions utilizing the basic routing protocol and algorithms.Type: GrantFiled: July 3, 2008Date of Patent: May 29, 2012Assignee: Silver Spring Networks, Inc.Inventors: Raj Vaswani, Sterling Hughes, Jana van Greunen, William E.

Publication number: 20120116602Abstract: To provide overall security to a utility management system, critical command and control messages that are issued to components of the system are explicitly approved by a secure authority. The explicit approval authenticates the requested action and authorizes the performance of the specific action indicated in a message. Key components of the utility management and control system that are associated with access control are placed in a physical bunker. With this approach, it only becomes necessary to bunker those subsystems that are responsible for approving network actions. Other management modules can remain outside the bunker, thereby avoiding the need to partition them into bunkered and non-bunkered components. Access to critical components of each of the non-bunkered subsystems is controlled through the bunkered approval system.Type: ApplicationFiled: November 4, 2010Publication date: May 10, 2012Applicant: Silver Spring Networks, Inc.Inventors: Raj VASWANI, Wilson Chuen Yew Yeung, Cristina Seibert, Nelson Bruce Bolyard, Benjamin N.

Patent number: 8161191Abstract: A method and system for providing a network and routing protocol for utility services are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a utility device (for example, a constant powered meter) sends network discovery messages to find the utility network. Neighboring meters are discovered and the device listens for advertised routes for one or more networks from the neighbors. The device is then registered with one or more utility networks, receiving a unique address for each network registration. Also illustrated in this invention disclosure is how each device of a class of devices (for example, battery powered meter) finds and associates itself with another device (for example, constant powered meter). The constant powered meter also registers its associate battery powered meter with the utility networks. The constant powered meter registers itself with the access points and the upstream nodes in the path out of each network.Type: GrantFiled: June 22, 2010Date of Patent: April 17, 2012Assignee: Silver Spring Networks, Inc.Inventors: George Flammer, Sterling Hughes, Daniel McKernan, Raj Vaswani

Patent number: 7962101Abstract: A method and system for providing a network protocol for utility services are disclosed are disclosed. In one embodiment, a computer-implemented method determines whether a measured real signal strength differs from a an accepted real signal strength by a configurable control limit parameter. In the event the measured real signal strength exceeds either an upper or lower bound based upon the configurable control limit parameter a determination is made whether there has been an unacceptable number of measured real signal strengths that exceed either an upper or lower bound based upon the configurable control limit parameter. In the event there has been an unacceptable number of measured real signal strengths that exceed either an upper or lower bound, which may include reaching or exceeding a configurable out of bound incidence limit, then a determination is made to calculate a new accepted real signal strength.Type: GrantFiled: April 4, 2007Date of Patent: June 14, 2011Assignee: Silver Spring Networks, Inc.Inventors: Raj Vaswani, Daniel McKernan, William San Filippo, III

Patent number: 7961740Abstract: A wireless network has a server that includes a server controller that controls the receipt and transmission of packets via a server radio. The server controller selects a route to nodes in the wireless network, and provides communication between the wireless network and at least one other network. A plurality of nodes in the wireless network include a node controller that controls the receipt and transmission of packets via a node radio, and selects a route to the server.

Patent number: 7839899Abstract: A method of updating routing information in a network where reboot information of other nodes in the network is used to determine whether a given node has recent route updates. If the reboot information indicates the given node has not recently rebooted, then routing information from that given node is used to update the routing information of the comparing node. The reboot information may be a reboot counter which is incremented by a node in response to the node going through a reboot process. When a node reboots, it may request the reboot counter from neighboring nodes. The received reboot counter is compared to the stored reboot counter for at least one node. The rebooting node may choose to receive routing information from a node which has not had its reboot counter changed from the stored reboot counter.Type: GrantFiled: March 28, 2008Date of Patent: November 23, 2010Assignee: Silver Spring Networks, Inc.Inventors: Jana van Greunen, Sterling Hughes, Raj Vaswani, William San Filippo, III

Publication number: 20100235209Abstract: Information relating to electrical energy usage for a given account is associated with a time segment that corresponds to a period when the electrical energy was received from an electrical energy distribution system. Electrical energy generation carbon impact information is retrieved for the corresponding time segment specifying when the electrical energy was received from an electrical energy distribution system. A carbon credit is calculated according to the retrieved electrical energy generation carbon impact information, and the retrieved electrical energy usage information associated with the time segment. The calculated carbon credit is then used to update a display of carbon credit related information, such as account balance, rate of carbon credit usage, currently applicable “cost” for carbon credit usage. Notifications can be provided to the consumer if any of this information crosses a threshold value.Type: ApplicationFiled: May 19, 2010Publication date: September 16, 2010Applicant: SILVER SPRING NETWORKS, INC.Inventors: Raj Vaswani, Sean M.
