Abstract: Mechanisms for switch upgrades using remote containers. An example system can export, to a server, a state of software processes associated with a first software container at the system. The system can generate a lightweight software container configured to forward traffic associated with the first software container to a second software container at the server, generated based on the state. The system can perform a switchover between the first software container and lightweight software container. The switchover can enable the lightweight software container to forward, to the second container, traffic associated with the first software container. The system can generate a fourth software container based on a snapshot of the second software container, and perform another switchover between the lightweight software container and fourth software container. The switchover can include enabling the fourth software container to handle traffic associated with the first software container, and disabling the lightweight software container.

Abstract: Aspects of the present disclosure are directed to dynamically adjusting control plane policing throughput of low (or lower) priority control plane traffic to permit higher throughput. The drop rate for low or lower priority control plane traffic can be determined to be above a threshold value. The processor utilization can be determined to be operating under normal utilization (or at a utilization within a threshold utilization value). The control plane policing for control plane traffic for the low or lower class of service can be increased (or decreased) to permit lower class of service control traffic to be transmitted using higher class of service resources without adjusting the priority levels for the lower class of service control traffic.
