Abstract: 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.

Abstract: The present disclosure presents systems and methods for obtaining metric information by a multi-core GSLB intermediary device and providing global server load balancing services using the obtained information. A first core of a multi-core GSLB appliance establishes a transport layer connection to a remote load balancer at a site of a plurality of sites. The first core transmits a message to each of the other cores of the multi-core GSLB appliance that the first core is a master core for receiving metric information from the load balancer. The first core receives metric information of the remote site from the load balancer. The first core propagates the metric information to each of the other cores of the GSLB appliance. A GSLB virtual server on a slave core receives a DNS request. The GSLB virtual server determines a DNS resolution for the DNS request based on the metric information.

Abstract: A centralized configuration of a Global Server Load Balancing (GSLB) site hierarchy may be batched across a plurality of appliances in a multi-site deployment. A single GSLB site hierarchy configuration may be distributed and operated on each appliance at each site. This reduces the configuration maintained for the multi-site deployment. Furthermore, in this manner, each appliance across multiple sites has an understanding of the entire topology of the multi-site deployment. Responsive to this configuration and understanding, each appliance may perform and optimize operations according to the site topology. For example, the appliances may selectively determine which sites to establish connections with in order to share metrics. In another example, appliances may select which remote sites to monitor services according to the topology.

Abstract: The present invention is directed towards systems and methods for aggregating and providing statistics from cores of a multi-core system intermediary between one or more clients and servers. The system may maintain in shared memory a global device number for each core of the multi-core system.

A first thread may generate aggregated statistics from a corresponding core by parsing the gathered data from the corresponding core. The first thread may transfer the generated statistics to a statistics log according to a schedule. The system may adaptively reschedule the transfer by monitoring the operation of each computing thread. Responsive to a request from a client, an agent of the client may obtain statistics from the statistics log.

Each packet engine may establish settings and parameters for load balancing based on the consolidated set of counter values.

Abstract: The present invention provides improvements to load balancing by providing a load balancing solution that distributes a load among a plurality of heterogenous devices, such as different types of local load balancers, using metrics collected from the different devices. The load balancing appliance collects metrics from heterogenous devices using a network management protocol and communication model, such as a Simple Network Management Protocol (SNMP). These heterogenous device metrics are available on the load balancing appliance with appliance determined metrics and metrics obtained by the appliance from homogenous devices using a metric exchange protocol. Via a configuration interface of the appliance, a user can select one or more of these different metrics for global load balancing. As such, the load balancing appliance described herein obtains a multitude of metrics from the different devices under management.

Abstract: Described are methods and systems for managing the connections between a client, an intermediary appliance and a server, so that asynchronous messages can be transmitted over HTTP from the server to a client. When a connection is established between a client and an intermediary, and the intermediary and a server to establish a logical client-server connection, that logical client-server connection is labeled and not maintained, while the connection between the client and the intermediary is maintained. Messages generated by the server and destined for the client are transmitted to the intermediary along with the connection label. The intermediary can then use the connection label to determine which client should receive the message.
