摘要： The invention provides a method for differentiated handling of VoIP call control messages according to their importance and functionality, thus providing to VoIP infrastructures a level of robust call control similar to that in PSTN networks. The invention works by classifying SIP messages by their type or content, and by allocating a VoIP call control server's resources to them according to a policy. The scheme also provides overload protection and prioritized handling of certain kinds of requests in VoIP call control servers.

摘要： A method for transporting Internet Protocols (IP's) over an Asynchronous Transfer Mode (ATM) network that exhibits the strengths of ATM, namely packet interleaving (using cell-based transport) with Quality of Service support for connection-oriented traffic (such as multiclass native ATM traffic and flows-based IP traffic using RSVP), while optimizing the connectionless requirements of existing IP traffic. Advantageously, both the IP protocol stack and ATM protocol stack operate as peers over ATM cell transport hardware. The method exploits an "implicit" signaling/control phase characteristic of IP traffic/protocols thereby minimizing setup. The implicit signaling phase is used to map a flow from a routed path to a switched path immediately upon transmission of a first packet. Similarly, particular packets may be immediately transported over the routed path even after establishment of the switched path. This mapping from the routed path to the switched path and vice versa is based upon the structure/semantics of the protocol driving the flow and not just the duration of the flow as done with prior-art methods. Consequently, while prior-art methods require cell-level counters to monitor activity (or lack thereof) for switching state, the method uses explicit control messages and soft-state at the IP level (as opposed to the cell level) to do the same. Advantageously, the method imposes no switching overhead as there is no coordination between neighboring nodes when a flow is moved from the routed path to the switched path.

摘要翻译： 一种通过异步传输模式（ATM）网络传输互联网协议（IP）的方法，该异步传输模式（ATM）网络展现了ATM的优势，即具有服务质量的数据包交织（使用基于单元的传输），支持面向连接的流量（如多类本机 ATM流量和基于流量的IP流量使用RSVP），同时优化现有IP流量的无连接要求。 有利地，IP协议栈和ATM协议栈都作为ATM信元传输硬件上的对等体来操作。 该方法利用IP流量/协议的“隐含”信令/控制阶段特性，从而最小化安装。 隐式信令阶段用于在传输第一分组时立即将来自路由路径的流映射到交换路径。 类似地，即使在建立切换路径之后，特定分组也可以立即通过路由路径传送。 从路由路径到交换路径的映射，反之亦然是基于驱动流程的协议的结构/语义，而不仅仅是流程的持续时间，如现有技术的方法所完成的。 因此，虽然现有技术方法要求小区级计数器监视切换状态的活动（或不存在），该方法使用显式控制消息和IP级（与小区级相反）的软状态来进行相同 。 有利地，该方法不施加切换开销，因为当流从路由路径移动到切换路径时，相邻节点之间没有协调。

摘要： A method and structure for a cloud service includes an API (application programming interface) as tangibly embodied in a set of computer-executable instructions and selectively executable on a computer on a network. The API provides a user interface for a cloud environment comprising one or more virtual machines to be selectively instantiated on at least one computer in the network upon a user request. A library is accessible via the API, the library providing definitions of components available to be instantiated in the cloud environment. The API automatically instantiates an image of a virtual network of components, as defined by a user input request and provides at least one cloud portal providing the user an access to exercise the instantiated virtual network image.

摘要： Techniques are disclosed for generating and managing presentities in accordance with a virtual presence server. By way of example, a method for requesting information from at least one server comprises the following steps. A client request, which expresses a request that can not be satisfied by a single existing presentity, is obtained at an intermediate server, wherein the intermediate server operates as a virtual presence server. The virtual presence server (i.e., intermediate server) creates a set of software objects for a virtual presentity, the set of objects embodying logic to combine presence information from one or more of existing presentities and external information sources, in accordance with at least one existing presence server. The virtual presence server creates an association between the request of the client and the created virtual presentity that allows the presence information to be propagated back to the client.

摘要： Customers are contacted on social media websites and instant messaging programs by monitoring a plurality of network-enabled user-interactive sites, e.g., social media websites, for an active presence of a customer on one of the sites. Upon detection of an active presence, a customer support agent is assigned to the customer associated, and a communication channel of customer's choice is established between the agent and the customer. This communication channel is used to exchange messages between the assigned agent and the associated predefined customer. A single contact center representation is established on each site, and a separate logical representation of each single contact center representation is established on premises equipment associated with the agent. The logical representation on the agent premises equipment is used to establish the communication channel between the customer support agent and the associated predefined customer.

摘要： The present invention is directed to a method for propagating contextual data in an audio communication by storing the contextual data obtained from a calling party in an extensible mark-up language formatted text document. A telephone call between a first party and a second party is converted to a session initiation protocol based voice over internet protocol communication, and the stored text document is attached to session initiation protocol messages that control the voice over internet protocol communication. The document is attached to the signaling messages by embedding the text document in a session description payload associated with the session initiation protocol message. The attached document is propagated with the audio communication, including when the signaling messages are used to transfer the audio communication from the second party to a third party or to add one or more addition parties to the audio communication.
