  • Patent number: 11418435
    Abstract: The present technology pertains to a group-based network policy using Segment Routing over an IPv6 dataplane (SRv6). After a source application sends a packet, an ingress node can receive the packet, and if the source node is capable, it can identify an application policy and apply it. The ingress node indicates that the policy has been applied by including policy bits in the packet encapsulation. When the packet is received by the egress node, it can determine whether the policy was already applied, and if so, the packet is forward to the destination application. If the egress node determines that the policy has not be applied the destination application can apply the policy. Both the ingress node and egress nodes can learn of source application groups, destination application groups, and applicable policies through communication with aspects of the segment routing fabric.

  • Patent number: 11411873
    Abstract: A first packet forwarding plane (PFE) of a network device may receive a packet and may perform a first lookup for the packet. The first PFE may provide the packet to a service plane based on the first lookup. The service plane may apply a service to the packet and may provide the packet to the first PFE. The first PFE may perform a second lookup. The first PFE may provide the packet to a second PFE of the network device based on the second lookup and may store flow information associated with the packet and second PFE information in a table. The network device may provide the flow information and the second PFE information from the table to the service plane to cause the service plane to send subsequent packets directly to the second PFE thereby saving fabric, memory, and processing bandwidth and improving overall network performance.

  • Patent number: 11382103
    Abstract: In environments such as buildings in which access points are densely deployed, those access points influence each other. To provide a frequency channel allocation scheme in such densely populated environments information gathered by the access points are collected. In such a situation, relying on a list of neighboring access points, background noise, communication medium business, the beacon messages received from access points as well as their associated RSSI, may lead to a frequency channel allocation scheme that may not significantly reduce the interference between access points. The invention introduces an activity-based distance computed between at least two access points which represents a time overlap in a use of the communication medium.

  • Patent number: 11356364
    Abstract: Techniques are provided for intelligent routing to a node in a network, such as a transport computer. A gateway server may receive authorization requests from a resource provider computer. There may be multiple potential transport computers to which to potentially route the authorization requests, depending on relationships established between the parties. A routing decision may be made automatically based on real-time network measurements and/or static rules. Real-time network measurements may be obtained by monitoring transport computers for failures, delays, or other undesirable activity. The routing decisions may further be based on expected volumes (e.g., based on analysis of historical spikes in volume). The routing decisions may further be based on user-configured rules and preferences, received via a routing administration interface.
