Abstract: Systems and methods provide for performing performance analytics processing of network traffic by copying packets of network traffic to a switch CPU based on a flag. The systems and methods disclosing receiving network traffic comprising one or more packet, generating a network traffic flow record associated with the received network traffic, the network traffic flow record including a copy-to-CPU bit and one or more function flag bits, setting the copy-to-CPU bit to an on configuration, processing the one or more packets by one or more functions to generate network flow analytics, wherein the one or more function flag bits are set in response to the one or more functions generating network flow analytics, and setting the copy-to-CPU bit to an off configuration.

Abstract: A system, computer-readable media, and methods for network resource sharing of routing and forwarding information are disclosed. The method may include receiving a first address for a device connected to a network and receiving one or more second addresses for the device. The method may also include identifying a first switch through which the device connects to the network and identifying a second switch for storing the first address and the one or more second addresses. Further, the method may include storing the first address in the first switch and storing the first address and the one or more second addresses in the second switch.

Abstract: 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.

Abstract: 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.

Abstract: At a network device configured to control access to a network, a client device authentication request is received from a client device. The request includes identity credentials and a temporary media access control (MAC) address of the client device. The client device is successfully authenticated based on the identity credentials. After authentication, a new MAC address is established in the client device. A data frame is received from at the network device. It is determined whether the client device is using the new MAC address based on the received data frame. If it is determined that the client device is using the new MAC address, the client device is permitted access the network.

Abstract: A method for allocating port assignments for transmitting a reserved network stream across a network node comprises determining a cycle time associated with a network node. The method also comprises establishing, for at least one port of the network node, a plurality of virtual layers associated with the cycle time, wherein each of the plurality of virtual layers is divided into 2n equally-spaced slots per cycle (where n>0). The method further comprises receiving a reserved stream request associated with transmission of a reserved stream across the node, and determining a number of slots required to transmit the reserved stream. The method also comprises assigning one or more slots associated with a port of the network node to the transmission of packets associated with the reserved stream based on the determined number of slots. The method further comprises transmitting the stream according to the slot assignment associated with the port of the network node.
