Publication number: 20240036993Abstract: Embodiments of the present disclosure are directed to dynamic shadow operations configured to dynamically shadow data-plane resources in a network device. In some embodiments, the dynamic resource shadow operations are used to locally maintain a shadow copy of data plane resources to avoid having to read them through a bus interconnect. In other embodiments, the dynamic shadow framework is used to provide memory protection for hardware resources against SEU failures. The dynamic shadow framework may operate in conjunction with adaptive memory scrubbing operations. In other embodiments, the dynamic shadow infrastructure is used to facilitate fast boot-up and fast upgrade operations.Type: ApplicationFiled: October 11, 2023Publication date: February 1, 2024Inventors: Riaz Khan, Peter Geoffrey Jones

Patent number: 11882060Abstract: An embodiment is directed to switchover operations with a mobile virtualized network device in a mobile device. The mobile virtualized hardware switchover operations may be used to selectively and temporarily provide virtualized control-plane operations to the data-plane of a non-redundant network device undergoing an upgrade or a reboot of its control plane. A non-redundant network device may operate hitless, or near hitless, operation even when its control plane is unavailable.Type: GrantFiled: November 22, 2022Date of Patent: January 23, 2024Assignee: Cisco Technology, Inc.Inventors: Riaz Khan, Atri Indiresan, Manas Pati

Patent number: 11863383Abstract: An exemplary method is disclosed that facilitate the on-demand creation of an exemplary instrumented network device in a cloud infrastructure, remote server, evaluation platform, or customized testing server and to form a stack between the instrumented network device as a debug network device and a target network device. The control plane of the target network device then switches over, via a switchover operation, to the control plane of the debug network device, while the data-plane of the target network device continues to operate. Once switched over, the instrumentation (e.g., hardware or software) of the control plane or debug network device facilitates the debug, optimization, profile, and/or recovery of the physical network device, even in a live network.Type: GrantFiled: June 27, 2022Date of Patent: January 2, 2024Assignee: Cisco Technology, Inc.Inventors: Riaz Khan, Atri Indiresan

Patent number: 11765254Abstract: Embodiments of the present disclosure are directed to protocol state transition and/or resource state transition tracker configured to monitor, e.g., via filters, for certain protocol state transitions/changes or host hardware resource transitions/changes when a host processor in the control plane that performs such monitoring functions is unavailable or overloaded. The filters, in some embodiments, are pre-computed/computed by the host processor and transmitted to the protocol state transition and/or resource state transition tracker. The protocol state transition and/or resource state transition tracker may be used to implement a fast upgrade operation as well as load sharing and or load balancing operation with control plane associated components.Type: GrantFiled: February 1, 2022Date of Patent: September 19, 2023Assignee: Cisco Technology, Inc.Inventors: Riaz Khan, Peter Geoffrey Jones

Patent number: 11190511Abstract: Techniques are disclosed relating to generating authentication information independent of user input. In some embodiments, an authentication application repeatedly performs operations to authenticate a client application to one or more hosts of a server system during an automated tasks. In some such embodiments, an instance of the operations includes receiving, from the client application, a request to generate authentication information. In response to the request, the authentication application may retrieve authentication data for the user and, independent of user input, generate an item of authentication information based on the authentication data. The authentication application may then output the item of authentication information to the client application, where the item of authentication information is usable by the client application to authenticate to at least one of the one or more hosts.Type: GrantFiled: January 29, 2019Date of Patent: November 30, 2021Assignee: salesforce.com, inc.Inventors: Jagadeesh Kunda, Ariel Anant Chavan, Qian Han, Yifan Wang, Kamran Riaz Khan, Vishal Agarwal
