  • Patent number: 8108677
    Abstract: The invention that addresses the problem of authentication of the transport packet stream (which constitutes a flow within a session), which has been admitted into a managed packet network. Authentication and the subsequent policing of the flows supporting an identified client's authorized service prevent a large class of denial of service attacks described below. Specifically, the invention addresses two different matters: 1) key distribution and management 2) various forms of using a shared key for the authentication of transport packets on the user-to-network-interface (UNI).

  • Publication number: 20110296518
    Abstract: Techniques are disclosed for efficient authentication of an end user device at an application server of a communication network. For example, wherein it is assumed that, in a communication network, a first computing device is an end user device, a second computing device is a gateway server, and a third computing device is an application server, a method comprises the following steps. The second computing device authenticates one or more packets received from the first computing device. The second computing device marks the one or more packets with a first-layer identity before routing the one or more packets toward the third computing device such that the third computing device is able to authenticate the one or more packets from the first computing device by confirming an association between the first-layer identity and a second-layer identity. For example, the first-layer identity may comprise a link layer identity assigned to the first computing device (e.g.

  • Publication number: 20110225643
    Abstract: In a communication network wherein a first computing device represents a resource owner and a second computing device represents a resource requestor, the resource owner detects an occurrence of an event, wherein the event occurrence represents a request to access one or more resources of the resource owner stored in a resource residence. The resource owner sends an authorization token to the resource requestor in response to the event occurrence, the authorization token serving as a proof of authorization delegated by the resource owner to be presented by the resource requestor to the resource residence so as to permit the resource requestor to access the one or more requested resources stored in the resource residence.

  • Patent number: 8000233
    Abstract: A method and apparatus for supporting end-to-end quality of service (QoS) reservations for an implicit reservations model are provided. The invention teaches how to implement implicit resource reservations using the open-standard Resource and Admission Control Function (RACF). A request for resources for a given reservation between an originating and a terminating point in a network is received. A central controller for that domain processes the request for a given domain to determine whether routes for said reservation are available and whether necessary bandwidth for said reservation is available. An implicit reservation and a release of the bandwidth are respectively accomplished with a specific number of messages. If the routes and bandwidth are available, the reservation for the given domain is confirmed and the reservation request is passed to another central controller for a next domain having resources required to satisfy the reservation request.

  • Patent number: 7752440
    Abstract: The proposed invention solves the problem of spoofing the origin to create e-mail spam, virus distribution, and other abuse of the electronic mail. In particular, it solves a notoriously dangerous problem of distributing computer viruses via e-mail allegedly sent from friends, colleagues, and well-respected organizations. The proposed invention defines a comprehensive set of mechanisms and apparatus to reasonably ensure that an e-mail message—when received by an e-mail gateway, e-mail relay server, or the destination e-mail server—has originated at the location and sent by a person (or a program) specified in its “From:” field.

  • Patent number: 7471951
    Abstract: A method and apparatus for establishing additional channels for a call between multi-task user terminals. A multi-task call (MTC) signaling module is used to receive requests for the addition or release of additional channels for a call. Through a signaling network, the module has access to the switches of a hybrid network for interconnecting edge switches connectable to MTC terminals. The MTC signaling module controls establishment or release of the connections between links of the paths through the hybrid network. Advantageously, an MTC terminal through its MTC signaling module can control the addition or release of channels through the hybrid network.

  • Publication number: 20080047401
    Abstract: The present invention relates to a torque connecting mechanism, which comprises a connecting rod with a continuous indicating part and a strength control part, the indicating part and strength control part are implemented at a location where torque strength or other stress is easy to be concentrated. The indicating part extends along the axis of the connecting rod. A stop part is implemented on the connecting rod, and strength indicating mechanisms are provided on both sides of the stop part, a lock ring is utilized to make a rotation handle stay securely around the connecting rod. The rotation handle has a base line for coinciding with a base point on the driving end of the connecting rod, which makes the base line of the rotation handle become another strength indicating mechanism of the stop part of the connecting rod. So it is easy to notice the condition of the deformation on the connecting rod whether the rotation handle is mounted on or detached from the connecting rod.

  • Publication number: 20070201513
    Abstract: The present invention specifies the mechanism for supporting end-to-end quality of service (QoS) reservations for an implicit reservations model using a Resource and Admission Control Function (RACF) apparatus. The invention teaches how to implement implicit resource reservations using the open-standard Resource and Admission Control Function (RACF), which is being standardized in ITU-T. Several methods are covered: 1) With a first method, a general distributed approach has been specified. 2) For a second method, the terminating RACF keeps the state of the reservations, so the resulting protocol is relatively simple, robust, and easy to implement. 3) A third method, which can be based on either of the above methods or their combination, starts reservations at both, the terminating and originating RACF ends and works toward the meet-me point.

  • Publication number: 20070124473
    Abstract: The present invention sets forth a methodology that allows involved processes to partition among themselves a pre-defined set of multi-type resources in a way that all processes end up satisfied with the outcome of the partitioning, and no central mediation for such partitioning is required. One exemplary embodiment of the invention sets forth a method of allocating multiple type resources among a distributed set of processes that includes the steps of selecting a process from the set of processes for partitioning the resources; partitioning the resources at the selected process; sharing results of the partitioning with others of the set of processes, wherein said other processes select a partition from the partitioned resources; the selected process being able to select a partition subsequent to the other processes having selected a partition. The method also repeats the above steps until all currently involved processes are satisfied by a selected partition of available resources.

  • Patent number: 6222826
    Abstract: A method and apparatus for establishing multimedia calls over an intelligent telecommunications network in which the calls are requested through an internetwork of client computers and server computers and the internetwork of client computers and server computers is further connected to the intelligent telecommunications network. The method involves: 1) a caller generating a request for a call utilizing the internetwork to initiate the request; 2) delivering multimedia and/or audiovisual presentations(s) to the caller via the internetwork and/or public switched telephone network (PSTN); and 3) completing a circuit switched telephone call between the caller and a destination user subsequent to the delivery of the presentations(s) wherein the call is placed from within the intelligent network itself. In this manner, one or more multimedia advertisements or other presentations are delivered to the originating caller before completion of the requested call.
