Publication number: 20260343493Abstract: Dynamic bandwidth expansion (DBE) with channel switching may be provided. Managing DBE with channel switching includes operating, by an access point (AP), at a baseline operating bandwidth. The AP expands from the baseline operating bandwidth to an expanded operating bandwidth for a client device associated with the AP. When the AP determines to switch from a first channel to a second channel, the AP reverts to the baseline operating bandwidth and switches from the first channel to the second channel.Type: ApplicationFiled: June 22, 2026Publication date: October 29, 2026Applicant: Cisco Technology, Inc.Inventors: Brian D.

Patent number: 12777021Abstract: This disclosure describes techniques and mechanisms for providing initialization vector (IV) uniqueness and extending rekeying windows for network devices that perform secure association sharing in multi-source and multi-destination environments. The techniques may apply to existing hardware of the network devices. The techniques may enable the network devices to execute in a non-XPN mode and establish secure tunnels corresponding to secure association sessions. The techniques may utilize software to partition extra bits included in packet headers. The network devices may perform a process to update a loop count value utilizing a portion of the extra bits, thereby exponentially extending the rekeying windows. Further, by utilizing a portion of the extra bits, the system may ensure IV uniqueness for the secure association session between network devices in the multi-source and multi-destination environment.Type: GrantFiled: November 5, 2024Date of Patent: October 27, 2026Assignee: Cisco Technology, Inc.Inventors: Wanli Wu, Scott Roy Fluhrer

Patent number: 12777409Abstract: Techniques and mechanisms for enabling an end-to-end controller of a network to offload decisions about placement of network slices to the transport controller. By doing so, the transport controller can intelligently determine optimal placement based on intent (e.g., external intent of the end-to-end controller and internal intent of the transport controller), internal transport network analytics functions, SLO/SLE constraints, real-time telemetry data, and more to provide dynamic and optimal placement of network slices. That is the described techniques dynamically utilize information from within the transport domain to define the placement of network slices. Thus, placements are more accurate, thereby reducing latency and improving functioning of the network, as well as providing an improved user experience by meeting SLO/SLE constraints.Type: GrantFiled: February 16, 2024Date of Patent: October 27, 2026Assignee: Cisco Technology, Inc.Inventors: Arghya Mukherjee, John J Mullooly, Robert Crowe, Waris Sagheer

Patent number: 12776904Abstract: Techniques and architecture are described that leverage a trusted cryptographic channel by a network controller to authenticate an unfamiliar host key found on a network device when the network controller is attempting to establish a secure connection over a secure channel. The network controller may authenticate an unfamiliar host key found on a network device by using the trusted cryptographic channel to retrieve the network device's host keys directly from the network device when the network controller encounters the unfamiliar host key. Additionally, the network controller may correlate all the audit events available to the network controller with the appearance of the unfamiliar host key and accepting the unfamiliar host key only if the unfamiliar host key is confirmed to be present on the network device and if the audit events indicate that the unfamiliar host key was recently properly installed or generated on the network device.Type: GrantFiled: November 18, 2024Date of Patent: October 27, 2026Assignee: Cisco Technology, Inc.Inventors: Deep Chand Patel, Kannan Krishnamurthy
