摘要： An improved method and apparatus are provided for queuing and triggering the flow of data across ATM networks. A connection is established between an insertion server and a client multiplexer. The insertion server prepares a timing response and establishes a transmit queue threshold for a pending trigger point for inserting data. The insertion server enqueues data. Responsive to receiving a timing request from the client multiplexer, the insertion server sends the timing response. Responsive to receiving a stream request from the client multiplexer, the insertion server transfers the enqueued data. The client multiplexer includes a timer for identifying an offset time between sending the timing request and receiving a timing response from the insertion server. The client multiplexer uses the offset time to set a count down timer for sending the stream request. The client multiplexer processes the data transferred by the insertion server and optionally sends a stop stream command to the insertion server.

摘要： Method and apparatus are provided for segmenting a multiple program multimedia digital data stream for transmission over a distribution communications network. Each program multimedia digital data stream includes sequential transport system (TS) packets with program clock references (PCRs) at a set time interval and a program identification (PID) associated with the PCRs. The multiple program multimedia digital data stream is received. The TS packets are decoded to identify the program clock references (PCRs). A selected number N of TS packets are identified. The multimedia digital data stream into frames responsive to both the identified number N of TS packets and the identified PCRs. A program identification (PID) associated with one of the PCRs is selected for timing the transmission of segmented multiple program multimedia digital data stream. A time interval following an identified PCR associated with the selected program identification PID is identified and compared with the set time interval between the program clock references (PCRs). Responsive to the identified time interval being greater than the set time interval, a new program identification (PID) is selected for timing the transmission of segmented multiple program multimedia digital data stream.

摘要： Methods, systems and computer program products are provided for which associate physical links of a network device to aggregator ports of the network device where there are more physical links of the network device capable of aggregation than aggregator ports of the network device. Physical links are associated with the aggregator ports of the network device based on a session invariant characteristic of the physical links until either all of the aggregator ports of the network device have been associated with physical links or all of the physical links capable of aggregation have been associated with an aggregator port. The remaining physical links are then utilized as single links to the network device irrespective of the physical link's capability to aggregate.

摘要： In pause time based flow control systems having station-level granularity, a station or switch may detect congestion or incipient congestion and send a flow control frame to an upstream station, commanding that upstream station to temporarily stop (pause) sending data for a period of time specified in the flow control frame. The traffic pause gives the downstream station time to empty its buffers of at least some of the excess traffic it has been receiving. Since each downstream station operates independently in generating flow control frames, it is possible for the same upstream station to receive multiple, overlapping pause commands. If an upstream station which is already paused receives subsequent flow control frames from the same downstream station that triggered the pause, the upstream station's pause timer is rewritten using the pause times in the successive flow control frames. If the upstream station receives flow control frames from different downstream stations, the upstream station updates the pause timer only if the pause time in the most recent flow control message is greater than the remaining part of the previously established pause time.
摘要翻译：在具有站级粒度的基于暂停时间的流量控制系统中，站或交换机可以检测拥塞或初始拥塞并向上游站发送流控制帧，命令上游站临时停止（暂停）发送数据一段时间流控制帧中指定的时间。流量暂停使下游站有时间清空其已经收到的至少一些超量流量的缓冲区。由于每个下游站在生成流控制帧时独立运行，所以相同的上游站可以接收多个重叠的暂停命令。如果已经暂停的上游站从触发暂停的同一下游站接收后续流控制帧，则使用连续流控制帧中的暂停时间来重写上游站的暂停定时器。如果上游站从不同的下游站接收到流量控制帧，则只有当最新流量控制消息中的暂停时间大于先前建立的暂停时间的剩余部分时，上游站更新暂停定时器。

摘要： A data processing system and method in a computer network are disclosed for improving performance of a link aggregation system included in the network. Parameters are established which are utilized to determine performance criteria of the link aggregation system. A performance of the link aggregation system is determined by determining the performance criteria. The performance of the link aggregation system changes in response to a flow traffic burden on the link aggregation system changing. The link aggregation system dynamically modifies the parameters in response to the changing performance of the link aggregation system. The link aggregation system is self-tuning and capable of automatically adjusting to a changing flow traffic burden on the link aggregation system.

摘要： A network switch as well as methods, systems and computer program products for controlling congestion at a granularity of less than a link are provided. Such finer granularity may be provided by pausing traffic at a source port level of a network switch. The network switch which transmitted a message which resulted in congestion being detected is notified of the congestion and pauses the communications from the source port of the message while maintaining communications over the link from other source ports. Such source port level congestion control may be provided by a network switch having a sub-queue of its output queues where each sub-queue corresponds to an input port. Source port level pausing of transmissions may then be provided by pausing the sub-queue associated with a source port.

摘要： A 2-bit communication channel is made to transmit complex data patterns by partitioning a digital string into 3-bit binary patterns which are encoded into 4 bits binary pattern and transmitted over the 2-bit communication channel in pairs using adjacent clock cycles on the 2-bit channel. Pre-defined ones of the 4-bit encoded data structures are used for framing on the channel and cannot be used to transmit data.

摘要： When multi-destination traffic is distributed through a host or switch, the decision to distribute each frame is performed by each egress port and not the ingress port. Within a link aggregation group, the multi-destination frame is sent to each of the egress ports within the link aggregation group. Each of such ports will then determine whether it should re-transmit the frame. If not, the frame is discarded.

摘要： An improvement in the Open Systems Interconnection model in which Service Access Points can be established directly between peer entities in the same layer of a protocol stack. This direct seamless peer-to-peer communication is vastly superior to the use of a higher level relay function to set up and manage the communication path. In particular, setup messages are exchanged between the peer entities and a higher layer to create the Service Access Point between the peer entities. The setup and management capabilities are contained in each of the peer entities and hence no relay function is required after the peer Service Access Point, substantially speeding up the communication and reducing the management overhead.
摘要翻译：开放系统互连模型的改进，其中服务接入点可以直接在协议栈的同一层中的对等实体之间建立。这种直接无缝的对等通信非常优于使用更高级别的中继功能来建立和管理通信路径。特别地，在对等实体和较高层之间交换建立消息以在对等实体之间创建服务接入点。设置和管理功能包含在每个对等实体中，因此在对等业务接入点之后不需要中继功能，大大加快了通信速度，降低了管理开销。
