    Abstract: In general, the disclosure describes techniques for lockless management of immutable objects by multi-threaded processes. A device comprising a processor may implement the techniques, where the processor execute a multi-threaded process including a producer thread and a consumer thread. The producer thread may instantiate an immutable object, and provide, to the consumer thread, a reference to the immutable object. The producer thread may also increment a reference counter to indicate that the reference has been provided to the consumer thread, where the reference counter is local to the producer thread and inaccessible to the at least two consumer threads. The producer thread may receive, from the consumer thread, a notification that the consumer thread has finished processing the immutable object, and decrement, responsive to receiving the notification, the reference counter. The producer thread may then delete, based on the reference counter, the immutable object.

    Abstract: A network device, associated with peer network devices, may receive policy information for a protocol; and compute a first update message based on information regarding a route associated with the policy information. The network device may determine that an upper utilization threshold for one or more of peer queues, associated with the peer network devices, is not satisfied; and write the first update message to the peer queues based on determining that the upper utilization threshold is not satisfied. The network device may compute a second update message based on the information regarding the route; determine that the upper utilization threshold for one or more of the peer queues is satisfied; and pause writing the second update message to the peer queues based on the upper utilization threshold being satisfied. The network device may permit the peer network devices to obtain data from corresponding ones of the peer queues.

    Abstract: In general, this disclosure describes techniques for a containerized router operating within a cloud native orchestration framework. In an example, a computing device comprises processing circuity; a containerized set of workloads; a containerized routing protocol process configured to execute on the processing circuitry and configured to receive routing information; a kernel network stack executing on the processing circuitry and configured to forward packets based on first routing information from the containerized routing protocol process; and a data plane development kit (DPDK)-based virtual router executing on processing circuitry and configured to forward traffic to and from the workloads based on second routing information from the containerized routing protocol process.
