Abstract: The present application discloses methods and systems for configuring and managing class-based condensation. One aspect thereof includes an automated mechanism to receive a user request for a document, retrieve the document from a content server, and compare the document to a base file of a document class. If a delta-difference between the requested document and the base file is less than a predetermined threshold value, create a condensed document by abbreviating redundancy in the requested document relative to the base file of the associated document class, associate the document with the document class, and transmit the condensed document to the user. The documents within a document class possess similar layouts.

Abstract: Systems and methods for managing data associated with incoming electronic messages including filtering incoming electronic messages according to the sender's address. In addition, a request/response technique categorizes sender's addresses as authorized, unauthorized, or unconfirmed, which categorizations are stored in associated data structure. The filtering processes and the categorization techniques can be used in connection with any of various methods for populating the data structures that identify sender's addresses associated with authorized and unauthorized senders. In this manner, recipients can effectively cause unsolicited electronic messages to be filtered out. Moreover, the processes generally do not require the recipient to view electronic messages and make decisions regarding whether the senders are to be categorized as unauthorized; rather, the timeliness and accuracy of the senders' responses determine whether specified senders are authorized or unauthorized.

Abstract: The present invention utilizes central offices, located on the edge of a network to route requests along the edge of the network. Once an edge client receives a request for information, the edge client makes a determination as to whether the edge client can provide the information requested. If the edge client cannot provide the information requested, then the edge client determines whether a routing instruction applies which specifies a second edge client. If the routing instruction applies, then the request is routed to the second edge client.

A mechanism is further provided to install information in the protocol enabled node so that it can function as the protocol proxy for the non-enabled mobile terminal.

Abstract: A method and system for providing flexible access resources or services related to particular software applications are described. The system includes a database of Internet sites that have been categorized so that the system determines the category of information that a user is accessing on the Internet. The system is also programmed so users are only allowed to access sites a limited number of times. The system is further programmed to limit a user's access to the Internet based on the network's current bandwidth usage. Moreover, users can requested a postponed access, wherein the resource or service they are requesting is stored to a server, and available to the user at a later time. In addition, if a user chooses to access a resource or service that is within certain predefined categories, they are presented with the option of retrieving the resource or service, but notified that their access will be logged to a file.

Abstract: A system for maximizing the efficiency of a load balancing server for an asymmetric web farm utilizes a TCP stack and data packets to send and receive client service requests. An internal buffer enables each web server in the web farm to balance their loading based on the contents of the client service request. Data switching between the address portion of the user space and the address portion of the kernel space within the load balancing server is eliminated.

Abstract: At least three storage devices are connected via a network to each other. Backup data is concurrently transferred from one of the storage devices, i.e., from a copy source storage device to other ones thereof, i.e., to copy destination storage devices. The amount of data transferred from the copy source storage device to each copy destination storage device is dynamically changed according to a state of a communication connection therebetween. At occurrence of a failure in the copy source storage device, necessary data can be concurrently read from the backup storage devices to restore the data in the copy source storage device at a high speed.

Abstract: A notification service that efficiently scales to the number and variety of notifications and users being serviced. The notification service is separated into three general functional components. A listener component receives a notification in a network format suitable for transmitting the notification over a network. The listener component translates the notification into an internal processing format used by the notification service. The notification is then forwarded to a routing component that determines a category associated with the notification, and performs a set of one or more operations on the notification based on its category. Finally, the notification service is forwarded to a delivery service for delivery of the notification to the notification sink. The listener component, the routing component, and the delivery component may each be scaled in order to adjust for current processing loads using load balancing functionality.

Abstract: A method and system are disclosed for efficiently matching incoming packets to previously forwarded outgoing packets within a network node to ensure a response received by a network node corresponds to a previously forwarded request. The network node receives an outgoing packet including state information and computes a mapping (e.g., hash) function value based upon the state information. Thereafter, the network node sets and entry within a bitmap at a position corresponding to the mapping function value. The network node also receives an incoming packet purportedly responsive to an earlier outgoing packet and includes state information of a type corresponding to the state information of an outgoing packet. The network node computes a mapping function value based upon the state information in the incoming packet. The network node then tests an entry corresponding to the mapping function value within one or more bitmaps including bits set at positions corresponding to previously forwarded outgoing packets.
