  • Patent number: 12764069
    Abstract: Disclosed is technology that allows a user to configure different load balance hash functions for each port channel to perform more custom-designed load balancing for that port channel. For example, some port channels may benefit from flow-based load balancing, whereas others may benefit from Virtual Local Area Network (VLAN) based load balancing, or load balancing based on an inner source media access control address (MAC address) and destination MAC address, or other methods. The present technology therefore allows a user to configure a port channel with a specific hash function that causes load balancing of the network traffic in a manner specific to that port channel.

  • Patent number: 12764094
    Abstract: A system and method are provided that use metadata encoded in a data flow to determine security actions to perform at a policy-enforcement point based on the security-chain context for the data flow that is provided by metadata (e.g., the security-chain context can include which security operations have been performed upstream on which data packets). The policy-enforcement point receives the data flow and the metadata, including attestations of the security operations that have previously (e.g., upstream) been applied to the data flow. Based on the attested to security operations, the policy-enforcement point selects what security actions to apply next to the data flow, e.g., additional security operations to apply, allow the data flow into a workload or trust zone, drop the workload, perform dynamic load balancing.

  • Patent number: 12764166
    Abstract: Techniques for expressing, communicating, de-conflicting, and enforcing consistent access policies between an IBN architecture and a Cloud-Native architecture. Generally, network administrators and/or users of a Cloud-Native architecture and an IBN architecture express access policies independently for the two different domains or architectures. According to the techniques described herein, a Network Service Endpoint (NSE) of the Cloud-Native architecture may exchange access policies with a network device of the IBN architecture. After exchanging access policies, conflicts between the sets of access policies may be identified, such as differences between allowing or denying communications between microservices and/or applications. The conflicts may be de-conflicted using various types of heuristics or rules, such as always selecting an access policy of the IBN architecture when conflicts arise.

  • Patent number: 12764592
    Abstract: Devices, networks, systems, methods, and processes for detecting and mapping Low Latency, Low Loss, and Scalable throughput (LAS) traffic are described herein. A device may determine that a data flow is LAS. The device can determine an initial Quality of Service (QoS) value associated with the data flow. The device may determine one or more network policies associated with one or more QoS levels. The device can determine a QoS ceiling value associated with a highest QoS level of the one or more QoS levels. The device may mark the data flow with the QoS ceiling value if the initial QoS value is lower than the QoS ceiling value, thereby mapping the data flow to the highest QoS level. The device can also maintain the initial QoS value if the initial QoS value is greater than the QoS ceiling value, as an exception to the one or more network policies.

    Abstract: Roaming optimization, and particularly transmitting directional neighbor reports to optimize roaming may be provided. For roaming optimization, it is first determined that a client is going to roam to a new Access Point (AP). In response to determining the client is going to roam to a new AP, an estimated path of the client is determined. One or more candidate APs are determined based at least in part on the estimated path, and probabilities of roaming to the one or more candidate APs is determined based at least in part on the estimated path. A directional neighbor report including a list of the one or more candidate APs and the probabilities is generated and transmitted to the client.

  • Patent number: 12764694
    Abstract: Provided herein are techniques to facilitate network slice service continuity in a mobile network environment. In one example, a method may include for a registration request involving a user equipment (UE), obtaining, by an Access and Mobility Management Function (AMF), subscription information identifying primary network slices backup network slices to which the UE is subscribed in which each of the primary network slices and the backup network slices are active network slices capable of actively handling sessions for multiple UEs. The method may further include determining whether there is registration capacity for the UE with each of the network slices with which the UE is allowed registration. Based on the determining that there is registration capacity for registration of the UE, the AMF can transmit a registration response to the UE that indicating registration with the first primary network slice and the first backup network slice is accepted.
