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 disclosure presents systems and methods for maintaining persistence of a backup virtual server on connections currently serviced by the backup virtual server. A virtual server operating on an intermediary network device and identified as a primary virtual server for a first connection may receive a request via the first connection. The intermediary device may forward the first request to a backup virtual server of the virtual server in response to identifying that the virtual server is unavailable. The intermediary device may later identify that the virtual server is available. The virtual server may establish a new connection responsive to receiving a connection request while the intermediary device may forward a second request received via the first connection to the backup virtual server instead of the virtual server responsive to identifying that the virtual server is configured not to preempt the backup virtual server from maintaining connections currently maintained by the backup virtual server.

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.

摘要： Described herein are systems and methods for improving networked communication systems by transforming IP addresses. In particular, an intermediary device disposed in a network between a plurality of clients and a plurality of servers can receive a request for a service offered at a specified domain name. The appliance can also receive a DNS-resolved primary address for a server associated with the domain name, and transform the primary address to a secondary address for the server. The address transformation can be done by the intermediary to prevent service interruption between a client and server due, for example, to server maintenance.

摘要： Systems, methods, apparatus and software can be implemented to detect memory leaks with relatively high confidence. By analyzing memory blocks stored in a memory, implicit and/or explicit contingency chains can be obtained. Analysis of these contingency chains identifies potential memory leaks, and subsequent successive verification confirms whether the potential memory leaks are memory leaks.

摘要： The present disclosure is directed to a system for managing spillover via a plurality of cores of a multi-core device intermediary to a plurality of clients and one or more services. The system may include a device intermediary to a plurality of clients and one or more services. The system may include a spillover limit of a resource. The device may also include a plurality of packet engines operating on a corresponding core of a plurality of cores of the device. The system may include a pool manager allocating to each of the plurality of packet engines a number of resource uses from an exclusive quota pool and shared quota pool based on the spillover limit. The device may also include a virtual server of a packet engine of the plurality of packet engines. The virtual server manages client requests to one or more services. The device determines that the number of resources used by a packet engine of the plurality of packet engine has reached the allocated number of resource uses of the packet engine, and responsive to the determination, forwards to a backup virtual server a request of a client of the plurality of clients received by the device for the virtual server.
