摘要： The present application is directed towards systems and methods for providing a cookie by an intermediary device comprising a plurality of packet processing engines executing on a corresponding plurality of cores, the cookie identifying a session of a user that was redirected responsive to a service exceeding a response time limit. The cookie may be generated with identifiers based off a name of a virtual server managing a service of a server, and a name of a policy associated with the virtual server. Each packet processing engine of the plurality of packet processing engines may interpret cookies generated by other packet processing engines due to the name of the virtual server and name of the policy, and may provide preferred client connectivity based on cookies included in requests for access to a service.

摘要： A method for sampling management includes establishing, for a multi-core intermediary comprising a plurality of packet evaluation components executing on a corresponding plurality of cores, a frequency at which the multi-core intermediary intercepts a response transmitted from a server to a client and injects data into the intercepted response. For each of the plurality of packet evaluation components, an offset and a frequency based on a number of packet evaluation components in the plurality of packet evaluation components is established, a combination of the established frequencies substantially similar to the frequency established for the multi-core intermediary. One of the plurality of cores intercepts a response from the server to the client, at a time specified by the frequency and the offset. The packet evaluation component executing on the one of the plurality of cores injects data into the intercepted response.

摘要： The present application is directed towards systems and methods for providing connection surge protection to one or more servers by an intermediary multi-core system. A packet processing engine of a multi-core device deployed as an intermediary between a plurality of clients and one or more servers determines an estimated number of total pending requests received by all packet processing engines based on a value of a local counter of received requests, the total number of pending requests received by all other packet processing engines at a last predetermined interval, and a rate of change of the total number of pending requests received by all other packet processing engines multiplied by the time since the last predetermined interval. The packet processing engine applies a surge protection policy to received pending requests responsive to the determined estimated number of total pending requests.

摘要： The present application is directed towards systems and methods for generating and maintaining cookie consistency for security protection across a plurality of cores in a multi-core system. A packet processing engine executing on one core designated as a primary packet processing engine generates and maintains a global random seed. The global random seed may be used as an initial seed for creation of cookie signatures by each of a plurality of packet processing engines executing on a plurality of cores of the multi-core system using a deterministic pseudo-random number generation function such that each core creates an identical set of cookie signatures.
