SYSTEMS AND METHODS FOR MANAGING SPILLOVER LIMITS IN A MULTI-CORE SYSTEM

The present disclosure is directed to a system for managing spillover via a plurality of cores of a multi-core device intermediary to a plurality of clients and one or more services. The system may include a device intermediary to a plurality of clients and one or more services. The system may include a spillover limit of a resource. The device may also include a plurality of packet engines operating on a corresponding core of a plurality of cores of the device. The system may include a pool manager allocating to each of the plurality of packet engines a number of resource uses from an exclusive quota pool and shared quota pool based on the spillover limit. The device may also include a virtual server of a packet engine of the plurality of packet engines. The virtual server manages client requests to one or more services. The device determines that the number of resources used by a packet engine of the plurality of packet engine has reached the allocated number of resource uses of the packet engine, and responsive to the determination, forwards to a backup virtual server a request of a client of the plurality of clients received by the device for the virtual server.
