Patent number: 11960534Abstract: Coordinating processing of audio queries is provided. A system receives a query. The system provides the query to a first digital assistant component and a second digital assistant component for processing. The system receives a first response to the query from the first digital assistant component, and a second response to the query from the second digital assistant component. The first digital assistant component can be authorized to access a database the second digital assistant component is prohibited from accessing. The system determines, based on a ranking decision function, to select the second response to the query from the second digital assistant component. The system provides, responsive to the selection, the second response from the second digital assistant to a computing device.Type: GrantFiled: April 8, 2019Date of Patent: April 16, 2024Assignee: GOOGLE LLCInventors: Bo Wang, Smita Rai, Max Ohlendorf, Venkat Kotla, Chad Yoshikawa, Abhinav Taneja, Amit Agarwal, Chris Ramsdale, Chris Turkstra

Patent number: 10432628Abstract: Disclosed are systems, methods, and computer-readable storage media for minimizing the number of entries in network access control lists (ACLs). In some embodiments of the present technology a networking device can receive, from a first computing device, a first data transmission intended for a second computing device, the first data transmission including first transmission data. The networking device can normalize at least a subset of the first transmission data based on a predetermined normalization algorithm, yielding a first normalized data set for the first data transmission. Subsequently, the networking device can identify a first access control list entry from a set of access control list entries based on the first normalized data set, the first access control list entry identifying a first action, and implement the first action in relation to the first data transmission.Type: GrantFiled: February 23, 2016Date of Patent: October 1, 2019Assignee: CISCO TECHNOLOGY, INC.Inventors: Thomas J.

Patent number: 9584421Abstract: Embodiments herein achieve proxy FHRP for anycast routing services through the coordination of L2MP edge switches to allow load balancing for the use of routing services. Such embodiments may avoid duplicity and coordinate control planes between the edge switches to present a proxy interface to the rest of the network for the routing services. As such, multipathing and load-balancing for efficient use of crucial services may be provided for client nodes inside the network.Type: GrantFiled: January 14, 2014Date of Patent: February 28, 2017Assignee: Cisco Technology, Inc.Inventors: Smita Rai, Chandan Mishra, Gayatri Ramachandran, Sanjay Sane

Patent number: 8873551Abstract: Techniques are described which facilitate multi-destination forwarding in a Layer 2 Multipath (L2MP) network which includes an emulated switch. The emulated switch may correspond to two or more underlying peer link switches in the L2MP network, in which each of the peer link switches is linked to a Classical Ethernet (CE) switch over a virtual port channel (vPC). Traffic received by one of the peer link switches over the vPC is automatically forwarded to the other peer link switch (or switches). Multi-destination frames originating from the L2MP network addressed to hosts within the CE network are sent over only one of the peer link switches.Type: GrantFiled: July 30, 2010Date of Patent: October 28, 2014Assignee: Cisco Technology, Inc.Inventors: Smita Rai, Gayatri Ramachandran, Santosh Rajagopalan, Chandan Mishra, Sanjay Sane, Hariharan Balasubramanian

Patent number: 8724517Abstract: A method is provided that includes configuring a first network element as a peer to a second network element. The first network element and the second network element are configured to execute a spanning-tree protocol (STP) in a network environment. The method may also include configuring a priority characteristic to be a same value for the first network element and the second network element such that both operate as root network elements for other network elements in the network environment.Type: GrantFiled: June 2, 2011Date of Patent: May 13, 2014Assignee: Cisco Technology, Inc.Inventors: Shekher Bulusu, Sanjay Sane, Smita Rai, Gayatri Ramachandran, Ronak Desai
