摘要： The SSL VPN session failover solution of the appliance and/or client agent described herein provides an environment for handling IP address assignment and end point re-authorization upon failover. The appliances may be deployed to provide a session failover environment in which a second appliance is a backup to a first appliance when a failover condition is detected, such as failure in operation of the first appliance. The backup appliance takes over responsibility for SSL VPN sessions provided by the first appliance. In the failover environment, the first appliance propagates SSL VPN session information including user IP address assignment and end point authorization information to the backup appliance. The backup appliance maintains this information. Upon detection of failover of the first appliance, the backup appliance activates the transferred SSL VPN session and maintains the user assigned IP addresses. The backup appliance may also re-authorize the client for the transferred SSL VPN session.

摘要： The present invention is directed towards systems and methods for providing static proximity load balancing via a multi-core intermediary device. An intermediary device providing global server load balancing identifies a size of a location database comprising static proximity information. The intermediary device stores the location database to an external storage of the intermediary device responsive to determining the size of the location database is greater than a predetermined threshold. A first packet processing engine on the device receives a domain name service request for a first location, determines that proximity information for the first location is not stored in a first memory cache, transmits a request to a second packet processing engine for proximity information of the first location, and transmits a request to the external storage for proximity information of the first location responsive to the second packet processing engine not having the proximity information.

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.
