摘要： A system to provide a multipoint processing terminal and a multicast bridging terminal to provide mixing, switching, and other processing of media streams under the control of H.323 components. Application Programming Interfaces defined for the multipoint processing terminal provide a multipoint control unit with the capability to change the default behavior of the multipoint processing terminal by allowing the multipoint control unit to control the routing audio and video streams in the multipoint processing terminal and control the media formats in a multipoint conference. Multipoint processing acceleration functionality is provided by providing interfaces to allow hardware accelerated implementations of multipoint processing terminals. The multicast bridging terminals enables clients using one type of control signaling and media streaming to join other conferences using different types of control signaling and media streaming by receiving audio or video data from an incoming media stream and performing any processing necessary to transform the media stream from the incoming stream data format to the outgoing stream data format.

摘要： Dynamic sizing of packets of data is disclosed. In one embodiment, a system includes a client and a server. The client receives packets of dynamic size, the client having a bandwidth. The server determines the dynamic size of the packets based on at least one factor. One such factor is the bandwidth of the client. The server sends the packets to the client.

摘要： A method and system for processing messages is provided. In a preferred embodiment of the present invention, a message scheduler, a job process, and a format resolution module are used. The message scheduler identifies when a new message is to be processed, schedules the new message for processing, invokes the format resolution module to determine a method of converting data in the message to an appropriate format for a destination device or file, and invokes a job process. The format resolution module determines an appropriate method for converting data in the message from a format acceptable to the source devices or files to a format acceptable to the destination devices or files and creates a target message containing a reference to a destination device or file. The job process sends the data between the source devices or files to a destination device or file and performs the appropriate conversion. The preferred embodiment of the present invention is designed to allow for the support of new devices and new data formats with little change to the existing system through the use of a building block methodology. Therefore, new devices and data formats can be supported in an easy and efficient manner.

摘要： A communication system including one or more host adapters connected to a host computer, each adapter having multiple serial communication ports for transferring data between the computer and several TTY devices. Several of the adapter's serial ports include a high speed serial link for communicating with a data concentrator. The adapter automatically detects the presence of a concentrator connected to a switchable port and switches to the high speed link. Each concentrator includes multiple serial ports for communicating with TTY devices, and a high speed serial link for communicating with the adapter's high speed link. The concentrators allow more than one TTY device to share a single adapter serial port. Data from all of the TTY devices is accumulated into an adapter data buffer during a configurable time period or until a certain amount of data is accumulated, at which time the adapter interrupts the computer and transfers the accumulated data to the computer in one transfer operation. Likewise, the computer accumulates data for the TTY devices and transfers this data to the adapter in one transfer operation. Communication between the adapters and concentrators through the high speed serial communication link is implemented using a small fixed-size addressed packet to achieve a low overhead, high performance communications protocol. Each high speed link between an adapter and a concentrator is implemented to provide inherent flow control of data. The concentrators include a fail safe global flow control mechanism to prevent overflow of data from the TTY devices.
摘要翻译：一种通信系统，包括连接到主计算机的一个或多个主机适配器，每个适配器具有用于在计算机和多个TTY设备之间传送数据的多个串行通信端口。几个适配器的串行端口包括用于与数据集中器进行通信的高速串行链路。适配器自动检测连接到可切换端口的集线器的存在并切换到高速链路。每个集线器包括用于与TTY设备通信的多个串行端口，以及用于与适配器的高速链路通信的高速串行链路。集线器允许多个TTY设备共享单个适配器串行端口。来自所有TTY设备的数据在可配置的时间段期间累积到适配器数据缓冲器中，或者直到一定量的数据被累积为止，此时适配器中断计算机并在一次传送操作中将累积的数据传送到计算机。同样，计算机累积TTY设备的数据，并在一次传输操作中将该数据传输到适配器。通过高速串行通信链路，适配器和集线器之间的通信使用小的固定大小的寻址分组来实现，以实现低开销，高性能的通信协议。实现适配器和集中器之间的每个高速链路以提供数据的固有流控制。集中器包括一个故障安全的全局流量控制机制，以防止来自TTY设备的数据溢出。
