A sender email client, in response to a request to send an email with attachment, determines whether a recipient of the email has distributed storage separate from an incoming email server of the recipient for storing email attachments. If so, a location server is consulted for the distributed storage's network address and its availability is determined. The send request is then serviced accordingly. An email service, in response to receiving an email with attachment, determines whether a recipient of the email has distributed storage for storing email attachments. If so, its network address and availability are likewise determined. The attachments are forwarded to the recipient's distributed storage for storage, when it becomes available. An email recipient client, in response to a request to access an email attachment, retrieves the attachment from the recipient's distributed storage or the incoming email server, as appropriate.

A system and method for collaborative filtering of data, such that accurate real time recommendations can be provided to users, without prior rating by users. The invention's main purpose is to discover the purchasing patterns of the users (customers) of a particular vendor (this includes stores or other points of sale, such as service businesses), whether they are virtual places on the Internet or conventional offline places. The present invention operates in two stages: In the preliminary stage the system reads the previous sales transactions, and makes various queries on previously collected user data, deriving rules. In the second phase, a user making a new request sends the request to the software component, where it is processed in relation to the rules. The result of this processing is a derivation of predictions and alerts concerning the users' information or purchase requests. The system also checks user baskets in order to predict if there are preferred items that have not been included, or determine whether there are unexpected items that may indicate buying mistakes or security warnings. The best modes of the invention are for use in online virtual stores and offline conventional stores. Such stores may be shops, vendors or service providers.

In embodiments of the invention, a method and apparatus for dynamic proxy insertion in network traffic path is described. According to one or more embodiments of the invention, a request and/or response message may be modified to include one or more thru-proxy tags to identify a network (or traffic) node (e.g., a proxy, server, or intermediary). For example, a request directed to a server or a response directed to a client may be altered to insert a plurality of intermediate or final destination designations. In so doing, a path of a request or response may be altered dynamically. A thru-proxy tag in a response may be inserted in a related request to identify a destination or node such that the request is sent to the destination in the thru-proxy tag before being sent to an origin server. Thru-proxy tags may be used to identify multiple and/or alternate destinations.

In current multimedia communication systems using session initiation protocols such as SIP, a service change (e.g. adding a new media type to an existing multimedia conversation) entails significant delays and processor load in both clients and server. The current invention solves this by separating session signaling and media control signaling in different signaling channels (141,142) and by eliminating the need to re-establish SIP sessions for each service change. The application server (120) maintains a list of all media types supported by each multimedia client (110) involved in a multimedia conversation. Each multimedia client (110) requesting to send one or several media streams with different media types to one or several other multimedia client(s) negotiates with the application server (120) only. The inventive concept significantly reduces networks delays and speeds up the service change as perceived by the user. The invention is of interest for various multimedia conferencing applications.

The method includes automatically selecting a master sending node and corresponding master receiving node in response to an omni-directionally transmitted request to send during a contention period. The method also includes selecting a slave sending node and corresponding slave receiving node if a spatial reuse ratio correspond to the master-node pair is less than a predetermined threshold and if directional data transmissions between the slave sending node and corresponding slave receiving node avoid interfering with directional data transmissions between the master nodes and other pairs of slave nodes. The method further includes causing the master sending node and slave sending node to directionally transmit data packets during a coordination period.

A method and system provide a user device with secure access to an enterprise application in an enterprise network through VPN. The enterprise application is accessed from a user device such that it sends and receives data packets through the VPN client. For this, a request to send packets, originating from the user application, is intercepted by a VPN agent associated with the user application. In turn, the VPN agent associates an address of a loop-back interface with the user application. Thereafter, packets sent by the user application, are re-directed to the VPN client through the loop-back interface. Similarly, packets received by the VPN client from the enterprise network are routed through the loop-back interface to the user application.

The present invention provides a system, method and apparatus for initiating and handling an emergency IP request using an IP enabled device having GPS capability. The IP enabled device is monitored for one or more emergency criteria. If the emergency criteria are satisfied, global positioning data is obtained using the GPS capability and the emergency IP request is sent to an address server. The address server receives the emergency IP request, obtains local emergency services data based on the global positioning data, dials a call center station based on the local emergency services data and passes an emergency call from the IP enabled device to the call center station. This invention can be implemented as a computer program embedded in a computer readable medium wherein the steps are performed by one or more code segments.

A device, system and method for adaptation of a collision avoidance mechanism or parameters of such mechanisms for a wireless network. For example, parameters of a contention window mechanism, a request-to-send mechanism, or other delay or collision avoidance mechanisms, may adaptively or dynamically be set or modified.

One or more audio/video files are provided on a central server (203), accessible via a computer network. A audio/video file is requested by a user (205) and the file is transmitted to that user for viewing (207). The user enters edit point information specifying a portion of the previously-transmitted audio/video file relating to which the user wishes to make an annotation. The edit point information is received (209) by the central server over the computer network along with the textual annotation entered by the user. Use may be made of an optional rule that the edit point information must satisfy before it is accepted (211). The received edit point information and textual annotation are stored in an annotation data file (213). A subsequent user may request the annotation data file, which is transmitted to that user. The annotation text along with the relevant portion of the audio/vide file is then displayed for the requesting user.

A method and device for adaptive control of transmission parameters such as data rate, fragmentation and request to send protection. Packet error rates for frames transmitted with and without request to send protection are computed and compared to determine whether error rates are attributable to noise or to collision. If error rates are attributable to noise, data rates may be adjusted and fragmentation may be activated. If error rates are attributable to collisions, request to send protection may be activated or adjusted.
