摘要： The present invention is directed towards systems and methods for managing a rate of request for an object transmitted between a server and one or more clients via a multi-core intermediary device. A first core of the intermediary device can receive a request for an object and assume ownership of the object. The first core can store the object in shared memory along with a rate-related counter for the object and generate a hash to the object and counter. Other cores can obtain the hash from the first core and access the object and counter in shared memory. Policy engines and throttlers in operation on each core can control the rate of access to the stored object.

摘要： The present disclosure presents systems and methods for maintaining operation of stateful sessions by a secondary multi-core appliance upon failover of a first multi-core appliance. A stateful session failover module of primary appliance may receive session states from each of the cores of the primary appliance. The stateful session failover module may communicate the session states of the cores of the primary appliance to a stateful session failover module of the secondary appliance. The stateful session failover module of the secondary appliance may update each of the cores of the secondary appliance with the session states. Upon failover, cores of the secondary appliance may maintain operation and features of the sessions handled by the primary appliance prior to failover using the received state sessions for each session maintained.

摘要： The present solution provides a spillover management technique for virtual servers of an appliance based on bandwidth. A network administrator may configure a bandwidth threshold for one or more virtual servers, such as virtual servers providing acceleration or load balancing for one or more services. The bandwidth threshold may be specified as a number of bytes transferred via the virtual server. The bandwidth threshold may also be specified as a round trip time or derivative thereof. A user may specify the bandwidth threshold via a configuration interface. Otherwise, the appliance may establish the bandwidth threshold. The appliance monitors the bandwidth used by a first virtual server. In response to detecting the bandwidth reaching or exceeding the bandwidth threshold, the appliance dynamically directs client requests to a second virtual server.
