Abstract: The present application is directed towards systems and methods for configuring and applying autoscaling to a service group of an intermediary device for a domain based server. All the IP addresses resolved by the domain name of the server and that are determined as up will automatically become members of the service group. The resolver monitor will resolve the server's domain name based on the TTL (Time to Live) value in the address record or whenever the appropriate command is executed. Each time the domain is resolved, if there is a change in the number of IP addresses resolved, then the members of the service group will shrink or expand based on the number of IP addresses resolved.

Abstract: The present invention is directed towards systems and methods for spillover threshold management in a multi-core system. A pool manager divides the spillover threshold limit of connections for vServers into an exclusive quota pool and a shared quota pool. Each vServer operating on a core is allocated an exclusive number of connections from the exclusive quota pool. If a vServer wishes to create connections beyond its exclusive number, the vServer can borrow from the shared quota pool. When the vServers are using at least a first predetermined threshold of their exclusive number of connections and the number of available connections in the shared quota pool has reached a second predetermined threshold, the multi-core system establishes a backup vServer.

Abstract: The present application is directed towards systems and methods for systems and methods for handling real-time streaming protocol sessions by an intermediary multi-core system. When a multi-core intermediary receives a setup request for a real-time streaming protocol session, the intermediary processes and forwards the request to a server providing the streaming media. The server sets up an RTSP session and transmits a session identification to the multi-core intermediary. A core of the intermediary receives the transmitted session identification and determines an owner core of the session, based on a hash of the session identification. The core transmits the session information to the determined owner core, which selects two consecutive ports on which to establish listening services. The owner core then notifies all other cores to establish listening services on the same consecutive ports, such that any core that receives an RTSP control message from a client can handle it properly.

Abstract: The present invention is directed towards systems and methods for handling limit parameters for multi-core systems. A pool manager divides the limited number of uses of a resource into an exclusive quota pool and a shared quota pool. Each packet processing engine operating on a core is allocated an exclusive number of uses of the resource from the exclusive quota pool. If a packet processing engine wishes to use the resource beyond its exclusive number, the packet processing engine must borrow from the shared quota pool.
