摘要： The present invention provides improvements to load balancing by providing a load balancing solution that allows a user to select metrics, weights and thresholds from metrics collected or determined by a load balancing appliance as well as metrics obtained from another device, such as a server running the service. The systems and methods described providing a load balancing technique in which load balancing decisions can be made based on metrics known by another device monitoring such metrics. The load balancing appliance uses a network management protocol and communication model, such as a Simple Network Management Protocol (SNMP), to identify and collect metrics from a server, service or other device. These metrics are available on the load balancing appliance with appliance determined metrics. Via a configuration interface of the appliance, a user can select one or more appliance determined metrics and/or the metrics obtained via the network management protocol to determine the load of a service.

摘要： 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.

摘要： The present invention provides maintains site persistence in a hierarchical Global Server Load Balancing (GSLB) deployment. Via configuration of GSLB services locally and remotely on each of the GSLB appliances and LB appliances at a site, a site appliance identifies and associates requests from the GSLB with the site. Furthermore, the site appliance may receive a GSLB cookie with the client request and confirms the request is from the expected GSLB in the site hierarchy. When the load balancers receives a response from a server, the appliance may include the GSLB cookie with the response back to the client. The appliance may also include an LB cookie to identify the server selected by the LB. When the client sends another request, the request may include the GSLB and LB cookie.

摘要： 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 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.

摘要： 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.
