Patent number: 11811555Abstract: The subject technology addresses a need for improving utilization of network bandwidth in a multicast network environment. More specifically, the disclosed technology provides solutions for extending multipathing to tenant multicast traffic in an overlay network, which enables greater bandwidth utilization for multicast traffic. In some aspects, nodes in the overlay network can be connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network.Type: GrantFiled: May 21, 2021Date of Patent: November 7, 2023Assignee: Cisco Technology, Inc.Inventors: Kit Chiu Chu, Thomas J. Edsall, Navindra Yadav, Francisco M. Matus, Krishna Doddapaneni, Satyam Sinha, Sameer Merchant

Patent number: 11689517Abstract: Methods and supporting systems for managing secure communications and establishing authenticated communications between processes of a computer application operating across network domains are provided. Authentication agents operate on servers hosting application processes, wherein each authentication agent has access to policies related to each of the application processes. An authentication agent operating on an originating server intercepts transmissions from an originating application processes and appends a trust profile associated with the originating application process. The transmission is released to a receiving server, where it is intercepted and validated at the receiving server by a second authentication agent on the receiving server.Type: GrantFiled: May 17, 2021Date of Patent: June 27, 2023Assignee: Palo Alto Networks, Inc.Inventors: Dimitri Styliadis, Satyam Sinha

Patent number: 10581635Abstract: Aspects of the subject technology relate to solutions for transporting network traffic over an overlay network. A first tunnel endpoint in an overlay network can receive an encapsulated packet from a second tunnel endpoint. The encapsulated packet may have been encapsulated at the second tunnel endpoint based on another packet originating from a source host that is associated with the second tunnel endpoint. The encapsulated packet can include a source host address for the source host and a source tunnel endpoint address for the second tunnel endpoint. The first tunnel endpoint can then update a lookup table based on an association between the source host address and the source tunnel endpoint address.Type: GrantFiled: May 16, 2017Date of Patent: March 3, 2020Assignee: CISCO TECHNOLOGY, INC.Inventors: Kit Chiu Chu, Thomas J.

Patent number: 10547544Abstract: Disclosed herein are methods of forwarding packets on a network, such as a leaf-spine network having leaf devices and spine devices. The methods may include receiving a packet at an ingress leaf device, and determining based, at least in part, on a header of the packet whether the packet is to be transmitted to a spine device. The methods may further include ascertaining based, at least in part, on a header of the packet whether to perform encapsulation on the packet, encapsulating the packet according to a result of the ascertaining, and then transmitting the packet to a spine device according to a result of the determining. Also disclosed herein are network apparatuses which include a processor and a memory, at least one of the processor or the memory being configured to perform some or all of the foregoing described methods.Type: GrantFiled: December 27, 2017Date of Patent: January 28, 2020Assignee: CISCO TECHNOLOGY, INC.Inventors: Thomas James Edsall, Navindra Yadav, Francisco M.

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.
