摘要： The present invention is directed towards systems and methods for providing dynamic proximity load balancing via a multi-core intermediary device. An intermediary device providing global server load balancing (GSLB) identifies a local domain name service (LDNS) entries database and assigns each LDNS entry in the LDNS entries database to one of the plurality of packet processing engine base on a source internet protocol (IP) address of each LDNS entry. The first packet processing engine on the appliance receives a LDNS request for an IP address, determines that the LDNS entry for the IP address is assigned to a second packet processing engine of the plurality of packet processing engines, transmits a request to the second packet processing engine for the LDNS entry for the IP address, and determines a response to the LDNS request based on the LDNS entry for the IP address received from the second packet processing engine.

摘要： 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. Additionally, the load balancing appliance described herein provides great flexibility in allowing the user to configure the global load balancer based on the user's understanding of these multitudes of metrics and to take into account the different characteristics and behaviors of the heterogenous devices.

摘要： The present solution provides a spillover management technique for virtual servers of an appliance based on bandwidth. A network administrator may configure a bandwidth threshold for one or more virtual servers, such as virtual servers providing acceleration or load balancing for one or more services. The bandwidth threshold may be specified as a number of bytes transferred via the virtual server. The bandwidth threshold may also be specified as a round trip time or derivative thereof. A user may specify the bandwidth threshold via a configuration interface. Otherwise, the appliance may establish the bandwidth threshold. The appliance monitors the bandwidth used by a first virtual server. In response to detecting the bandwidth reaching or exceeding the bandwidth threshold, the appliance dynamically directs client requests to a second virtual server.

摘要： In a method and appliance for determining responsiveness of a service via a particular protocol, a device intermediary to a plurality of clients and a plurality of services determines response times from each of a plurality of services to respond to requests via a first type of protocol of a plurality of protocols. The device calculates an average response time for the first type of protocol from each of the response times of the plurality of services. The device establishes a predetermined threshold for which a response time of a service for the first type of protocol may deviate from the average response time. The device identifies a service as available responsive to determining that a deviation of the response time of the service from the average response falls within the predetermined threshold.
