    Abstract: A method and device for preventing fraud in international calls in a long-distance telecommunications system, where selected customers can avoid fraud control blocks and greater granularity is achieved in blocking international destinations. In the method and device, an override flag is created in the records of the Billing Number Screening (BNS) database. When a call is made using a billing number whose corresponding record has the override flag set, the call is not stopped by fraud control blocks on certain international destinations. In addition, international destinations can be blocked with greater specificity because a Country Set Logic (CSET) field is added to the International City Code Database. The addition of CSET to this database allows particular international city destinations to be blocked from certain origin points.

    Abstract translation: 一种用于在长途电信系统中防止国际呼叫中的欺诈的方法和装置，其中选择的客户可以避免欺诈控制块和更大的粒度来阻止国际目的地。 在方法和设备中，在记帐号码筛选（BNS）数据库的记录中创建一个覆盖标志。 当使用其对应记录设置了超驰标志的记帐号进行呼叫时，在某些国际目的地的欺诈控制块不进行呼叫停止。 另外，由于国际集合逻辑（CSET）字段被添加到国际城市代码数据库中，所以可以更加专门地阻止国际目的地。 将CSET添加到此数据库允许特定国际城市目的地从某些原点被阻止。

    Abstract: A system controls the flow of traffic in a network, especially an Ethernet-based network. The system receives a flow control message indicating that traffic flow to a downstream device is to temporarily cease and determines an appropriate flow control action based on a set of control policies in response to the flow control message. The system then performs the selected flow control action.

    Abstract: A network architecture in accordance with the present invention includes a communication network that supports one or more network-based Virtual Private Networks (VPNs). The communication network includes a plurality of boundary routers that are connected by access links to CPE edge routers belonging to the one or more VPNs. To prevent traffic from outside a customer's VPN (e.g., traffic from other VPNs or the Internet at large) from degrading the QoS provided to traffic from within the customer's VPN, the present invention gives precedence to intra-VPN traffic over extra-VPN traffic on each customer's access link through access link prioritization or access link capacity allocation, such that extra-VPN traffic cannot interfere with inter-VPN traffic. Granting precedence to intra-VPN traffic over extra-VPN traffic in this manner entails special configuration of network elements and protocols, including partitioning between intra-VPN and extra-VPN traffic on the physical access link using layer 2 multiplexing and the configuration of routing protocols to achieve logical traffic separation between intra-VPN traffic and extra-VPN traffic at the VPN boundary routers and CPE edge routers. By configuring the access networks, the VPN boundary routers and CPE edge routers, and the routing protocols of the edge and boundary routers in this manner, the high-level service of DoS attack prevention is achieved.

    Abstract translation: 根据本发明的网络架构包括支持一个或多个基于网络的虚拟专用网（VPN）的通信网络。 通信网络包括通过属于一个或多个VPN的CPE边缘路由器的接入链路连接的多个边界路由器。 为了防止客户VPN外的流量（例如，来自其他VPN或互联网的流量）降低客户VPN内的QoS提供的流量，本发明优先于超过VPN的流量， 每个客户的访问链接通过访问链路优先级或访问链路容量分配，使得超VPN流量不能干扰VPN间流量。 以这种方式优先考虑超VPN流量的VPN内流量需要特殊配置网元和协议，包括使用第2层复用和路由协议配置在物理接入链路上进行VPN内VPN和VPN之间的流量分区 实现VPN边界路由器和CPE边缘路由器之间的VPN内流量与VPN外流量之间的逻辑流量分离。 通过以这种方式配置接入网络，VPN边界路由器和CPE边缘路由器以及边缘和边界路由器的路由协议，实现了DoS攻击防范的高级服务。

    Abstract: A data model of a modeled environment is maintained within a database. The data model includes data defining a plurality of hierarchically arranged subsets of space within the modeled environment and data defining a plurality of items populating the modeled environment. A data processing system displays within a display device at least first and second windows. The first window displays a map of the modeled environment, where the map includes at least one user-selectable graphical element representing one of the plurality of hierarchically arranged subsets of space or one of the plurality of items. In response to a first user input, a graphical element is copied from the first window and displayed within the second window. In response to a second user input selecting the graphical element within the second window, data from the database associated with the subset of space or item represented by the graphical element is presented.

    Abstract: In a SIP network, SIP servers are provisioned with information used to authenticate subscribers and entities that will be placing calls. This information can be used during call establishment to allow or deny calls, as well as to determine the appropriate party to bill if the call involves a charge, such as a long distance charge. In addition to allowing calls between authenticated and trusted entities, there is a need for the SIP server to allow certain kinds of calls that involve non-trusted users or entities. If non-trusted entities where not recognized, trusted users and entities within the SIP network would not be able to receive calls from users or entities not know to the SIP server that is providing them services.

    Abstract translation: 在SIP网络中，SIP服务器配置有用于验证将要拨打电话的用户和实体的信息。 在呼叫建立期间可以使用该信息来允许或拒绝呼叫，以及如果呼叫涉及诸如长途电话的费用，则确定适当的账单方。 除了允许经过身份验证和受信任的实体之间的呼叫之外，还需要SIP服务器允许涉及不可信用户或实体的某些类型的呼叫。 如果不认可的不信任实体，SIP网络内的信任用户和实体将无法从提供服务的SIP服务器不知道的用户或实体接收呼叫。
