Abstract: Systems and methods of vertical auto-scaling a networking stack by adjusting the number of packet engines executing on a device are provided. A device intermediary to clients and servers executes first packet engines to process network traffic of a first set of connections. The device determines to adjust the number of packet engines executing on the device based on trigger parameters. The device activates second packet engines to process network traffic for a second set of connections. The device mirrors the network traffic from the first and second set of connections. The first packet engines reject the traffic from the second connections, and the second packet engines reject the traffic from the first connections. The device deactivates the first packet engines when the first connections timeout.

Abstract: Managing an autoscaled user space networking stack is provided. A cluster of containers are disposed in a userspace separate from a kernel space of a device. Each container in the cluster of containers can execute a respective one of a plurality of virtual functions, for a network interface card of the device, to cause packets received by the device to bypass the kernel space. The device can forward, via a load balancing technique, a packet received by the device to a container in the cluster of containers. The container can execute a virtual function of the plurality of virtual functions. The device can update a queue for a core managed by the virtual function. The update can cause the core to process the packet in accordance with the queue.
