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: Presented herein is an exemplified system and method that provides visibility, for traffic analytics, into secured encapsulated packet (e.g., secure VXLAN-GPE packet, a secure metadata-GPE packet or other GPE standards). The exemplified system and method facilitate encryption of traffic in a granular manner that also facilitate the monitoring of said secure traffic in a fabric network in an end-to-end manner throughout the network. Such monitoring can be beneficially used for analytics, performance analysis, and network debugging/troubleshooting.

Abstract: Systems, methods, and computer-readable media for monitoring traffic in a network include receiving, at an analytics platform connected to the network, one or more encapsulated packet headers from one or more network nodes of the network. From the one or more encapsulated packet headers, at least one or more source addresses of the one or more network nodes which transmitted the encapsulated packet headers, and one or more timestamps at which the one or more encapsulated packet headers were transmitted from the one or more network nodes may be determined. From at least the one or more source addresses and timestamps, network traffic information such as one or more of latency or jitter of data packets transiting through the one or more network nodes may be determined, wherein the one or more encapsulated packet headers may correspond to the data packets transiting through the one or more network nodes.

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: 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.
