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： 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.

摘要： In a method and appliance for using a dynamic response time to determine responsiveness of one or more network services on a server, a monitor determines a response time for each of one or more network services. The monitor establishes an average response time based on the determined response time for each of the one or more network services. The monitor associates with the established average response time a predetermined threshold for which the response time of the one or more network services may deviate from the average response time and maintain an indication of responsiveness. The monitor monitors the response time of the one or more network services to one or more requests. The monitor determines that the response time of the one or more network services deviates from the average response time by the predetermined threshold. The monitor indicates that the one or more network services are unavailable.

摘要： An apparatus, method and computer program product for guaranteeing network client-server response time while providing a way of putting the client on-hold when the response time temporarily prohibits access to the requested server. The apparatus is implemented within an interface unit connecting a plurality of servers and an on-hold server to the Internet, which is connected to a plurality of clients. According to one aspect of the invention, the method includes the steps of opening a connection between a client and the interface unit; determining which server the client desires a page from; determining the current response time of the requested server; if the response time is acceptable then opening a connection between the interface unit and the requested server if no free connection is open between the interface unit and the requested server; allowing the client to access information on the requested server-via the connections; and closing the connection between the client and the interface unit while keeping open the connection between the interface unit and the requested server. Alternatively, if the response time is not acceptable, then putting the client on-hold by redirecting the client to an on-hold server until the response time of the requested server becomes acceptable. According to a “on-hold distribution” aspect of the invention, the interface unit determines the on-hold preference of the client and selects the server hosting that on-hold preference. According to another aspect of the invention, instead of utilizing the interface unit, each server has the intelligence to put the client on-hold when applicable.

摘要： The present invention is directed towards systems and methods for dynamically deploying and executing acceleration functionality on a client to improve the performance and delivery of remotely accessed applications. In one embodiment, the client-side acceleration functionality is provided by an acceleration program that performs a transport layer connection buffering technique for improving performance of communications and delivery of a remotely-accessed application. The acceleration program establishes a transport layer connection from the client to the server and buffers requests of the client based on determining a difference between a rate of consumption of responses received by the client from a server and a rate of production of requests transmitted by the client to the server. As such, the acceleration program can throttle transmissions of the client if the client's rate of consumption falls behind the rate of submission of requests.

摘要： The present disclosure describes systems and methods for load balancing multiple application delivery controllers (ADCs) in multiple tiers. An upper layer of the tier comprises ADCs that load balance the plurality of ADCs of a lower layer of the tier. In order to appropriately share and maintain client IPs for transparent cache redirection scenarios, the transport layer (Transport Control Protocol (TCP)) port range is split among the ADCs of the lower tier. The lower tier ADCs would then create a connection only using a source port assigned to them. The response from the origin will then be sent to the upper level ADC which looks at the destination port and forward the packet to the correct lower tier ADC. Hence, the ADCs at two levels will work in conjunction to provide transparent cache direction.
