Abstract: The present solution allows users, such as administrators to configure slow start parameters for new services. These slow start parameters specify a rate at which requests should be given to a newly added or up service. The users can also chose to automatically increase the load in multiples of the chosen rate by specifying an increment interval. The services are given the configured rate for the interval, and once the interval is reached, the next multiple of the rate of requests is given. The increase of rate of requests is done automatically until an existing service request rate is reached. At that point in time this functionality is disabled and the existing and new services are treated the same.

Abstract: The present invention is directed towards a method for using a listening policy for a virtual server on an intermediary device. An intermediary device establishes for a first virtual server a first listening policy with an expression for evaluating packets received by the intermediary device to determine whether the packet may access the first virtual server. The intermediary device listens for packets at a first internet protocol (IP) address and a first port specified for the first virtual server. Then, the intermediary device evaluates the expression of the first listening policy to a first packet received at the first IP address and first port and determines whether to provide the first packet to the first virtual server based on a result of the evaluation.

Abstract: The present invention is directed towards systems and methods for using a distributed hash table to maintain the same configuration and resource persistency across a plurality of cores in a multi-core system. The distributed hash table includes a plurality of partitions, each partition being owned by a respective core of the multi-core system. A core may establish resources in the partition it owns. A core may request other cores to establish resources in the partitions they own and send resource information to the core. The core may locally cache the resource information.

Abstract: The present application is directed towards ASDR table contract renewal. In some embodiments, a core may cache an ASDR table entry received from an owner core such that when the entry is needed again the core does not need to re-request the entry from the owner core. As storing a cached copy of the entry allows the non-owner core to use an ASDR table entry without requesting the entry from the owner core, the owner core may be unaware of an ASDR table entry's use by a non-owner core. To ensure the owner core keeps the ASDR table entry alive, which the non-owner core has cached, the non-owner core may perform contract renewal for each of its recently used cached entries. The contract renewal method may include sending a message to the owner core that indicates which cached ASDR table entries the non-owner core has recently used or accessed. Responsive to receiving the message the owner core may reset a timeout period associated with the ASDR table entry.

The intermediary receives the request from the cache server responsive to a cache miss, the received request maintaining the original source and destination IP addresses. The intermediary identifying that the third request is coming from the cache server via one or more data link layer properties of the third transport layer connection.
