摘要： Server-determined client refresh periods (CRPS) for dynamic directory services are disclosed. In a dynamic directory maintained by a server, clients must send a refresh message to the server every CRP in order to persist in the directory. The server desirably initially sets the CRP for the clients, and is able to later change the CRP. This allows the server to increase the CRP for at least some of the clients as more clients log onto the server, to ensure that the server is able to timely respond to all the clients.

摘要： Conferencing data is reliably delivered to computer systems participating in a hierarchically arranged multi-cast conferencing session. When a child computer system does not receive a multi-cast packet (e.g., an IP multi-cast packet), the child computer system sends a negative acknowledgment to a parent computer system. In response, the parent computer system re-transmits conferencing data that was contained in the multi-cast packet to the child computer system. Conferencing data can be re-transmitted to the child computer system via uni-cast (e.g., TCP). Accordingly, conferencing data that is not received or that is damaged via multi-cast can be repaired via uni-cast. Computer systems can join an existing multi-cast conference session without having to communicate with the root computer system. The root computer system adjusts a multi-cast send rate to compensate for changed network conditions.

摘要翻译： 会议数据可靠地传递给参与分层安排的多播会议会话的计算机系统。 当子计算机系统不接收多播分组（例如，IP多播分组）时，子计算机系统向父计算机系统发送否定确认。 作为响应，父计算机系统将包含在多播包中的会议数据重新发送到子计算机系统。 可以通过单播（例如TCP）将会议数据重新发送到子计算机系统。 因此，可以通过单播来修复未被接收或被多播损坏的会议数据。 计算机系统可以加入现有的多播会议会话，而无需与根计算机系统进行通信。 根计算机系统调整多播发送速率以补偿已更改的网络条件。

摘要： Selecting a source account for an outgoing communication content of a user is described. A collection of source accounts is associated with the user. Each source account has an individual content storage storing communication content associated with the corresponding source account. A user's authentication is validated for using the collection of source accounts. One source account in the collection is designated as a primary source account. The source accounts in the collection are aggregated to a primary content storage. The user is authenticated to sign in to the primary source account. Instructions are received from the user for generating a communication content from the primary source account and the primary content storage. Instructions are received from the user for selecting one of the source accounts in the collection as the source account for the generated communication content, and the user is signed in to the primary source account.

摘要： In order to minimize the delay of the video images viewed by a network conference attendee, an intelligent buffering process (IB process) selectively discards video frames from at least one point, and in an embodiment, many network points, such as at “in” and/or “out” buffers of clients, servers, routers, etc. Packets of video frame data arrive at a buffer, which can fill to a predetermined limit if the packets cannot be forwarded due to delays or slow connections. To forward the most current video images, old frames in the buffer are discarded rather than forwarded. In a particular embodiment, when the buffer is full, the next arriving delta frame packet is discarded. To avoid distortion, each subsequent delta frame is discarded until a new key frame eventually arrives. If the buffer is still full when the key frame arrives, the buffer is purged and the new key frame is added.

摘要： A method for establishing a hybrid voice session between a mobile device and a VoIP device is disclosed. A caller using a mobile device in a mobile network initiates a request for a voice session by clicking on a virtual identifier, e.g. an email address, provided for the callee in an address book on the caller's mobile device. If the callee is online, then the request is enabled. In one embodiment, the request is enabled by creating a call registration record using a mobile data network. In another embodiment, the request is enabled by having the caller interact with an IVR system. In yet another embodiment, a caller can interact with the IVR system from any type of telephone device. The callee is notified regarding the voice session, and if accepted, the hybrid voice session is established via a voice channel and a VoIP channel.
