    Abstract: PROBLEM TO BE SOLVED: To provide a facility for creating and using a unique identifier as a key for identifying a unique user agent instance from a plurality of use agents of the same user. SOLUTION: The facility creates an identifier for a first user agent instance serving as one instance of one user inside one application instance (S402). The facility uses the identifier for registering the first user agent instance to a logical server (S404) and associates the identifier with a pair consisting of the first user agent instance and registration to the logical server (S408). Then, the facility uses the identifier for registering the first user agent instance to the logical server afterward (S414). COPYRIGHT: (C)2006,JPO&NCIPI

    Abstract: This document describes tools that enable fault-tolerant resource committal for a system having computing devices needing to have operations of a particular type performed by one of multiple external resources. The tools may do so without relying on leadership from a pre-selected or altered computing device. Assume, for example, that the system is a conferencing system, the computing devices are front-end servers, the operations of a particular type are those that require handling of audio from users in the conference, and the external resources are homogeneous audio multi-point control units (MCUs) each of which is capable of handling audio from all of the users. The tools may enable, in one embodiment, any of the front-end servers to allocate a single audio MCU and commit all of the other front-end servers to use that single MCU for their audio operations.

    Abstract: Protocol architecture for wiring media streams and specifying mixing behavior in a multipoint control unit. The protocol provides the capability to expose the core mixing algorithms to modification for mixing media without dealing with the functionality of the mixer itself (e.g., ports and IP specifics). The protocol facilitates the wiring of input media streams to output media streams by changing the mixing behavior via changes to the mixing algorithms using the protocol. The protocol operates based on a schema that includes controls related to route, wire, and filter for the mixer input and mixer output.

    Abstract translation: 协议架构，用于连接媒体流并指定多点控制单元中的混音行为。 该协议提供了将核心混合算法公开于混合介质的修改而不涉及混频器本身的功能（例如，端口和IP细节）的能力。 该协议通过改变使用该协议的混合算法来改变混合行为，从而有助于将输入媒体流连接到输出媒体流。 该协议基于一个模式运行，该模式包括与混频器输入和混频器输出的路由，导线和滤波器有关的控制。

    Abstract: A control server initiates a call to a first device. After creating a connection to the device, the control server reverses the direction of the message flow between the device and the control server such that the device becomes the initiator of the call (the caller) and the control server becomes the device that is called (the callee). A connection is also established between the first device, the control server and a second device that is an endpoint for the call. Early media and forking is available to the first device after reversing the direction of the message flow between the first device and the control server and the callee has been contacted. Additionally, information flows between the first device and the second device through the control server as if the first device and the second device were directly connected.

    Abstract translation: 控制服务器向第一个设备发起呼叫。 在创建与设备的连接后，控制服务器反转设备与控制服务器之间的消息流的方向，使得设备成为呼叫的发起者（呼叫者），并且控制服务器成为被呼叫的设备 被调用者）。 第一个设备，控制服务器和作为呼叫端点的第二个设备之间也建立连接。 在第一个设备和控制服务器之间的消息流的方向颠倒并且已经联系了被叫方之后，早期的媒体和分岔可用于第一个设备。 另外，信息通过控制服务器在第一设备和第二设备之间流动，就好像第一设备和第二设备直接连接一样。
