    Abstract: A method for scoring queued frames (18) for selective transmission through a switch (12) includes providing one or more switches in a fibre channel fabric, particularly one or more fibre channel switches (12'). The method includes assigning an initial score (20) to the content (42) of the one or more frames (18) of data (26). The initial score (20) is adjusted by one or more alternative score components to determine one or more adjusted scores (22). The adjusted scores (22) are compared. The method also provides for selecting frames (18) having the highest adjusted scores (22) and transmitting through the switches (12) the frames (18) having the highest adjusted scores (22).

    Abstract: Quality of Service (QoS) support is provided by means of a Tiered Contention Multiple Access (TCMA) distributed medium access protocol that schedules transmission of different types of traffic based on their service quality specifications. In one embodiment, a wireless station is supplied with data from a source having a lower QoS priority QoS(A), such as file transfer data. Another wireless station is supplied with data from a source having a higher QoS priority QoS(B), such as voice and video data. Each wireless station can determine the urgency class of its pending packets according to a scheduling algorithm. For example file transfer data is assigned lower urgency class and voice and video data is assigned higher urgency class. There are several urgency classes which indicate the desired ordering. Pending packets in a given urgency class are transmitted before transmitting packets of a lower urgency class by relying on class-differentiated urgency arbitration times (UATs), which are the idle time intervals required before the random backoff counter is decreased. In another embodiment packets are reclassified in real time with a scheduling algorithm that adjusts the class assigned to packets based on observed performance parameters and according to negotiated QoS-based requirements. Further, for packets assigned the same arbitration time, additional differentiation into more urgency classes is achieved in terms of the contention resolution mechanism employed, thus yielding hybrid packet prioritization methods. An Enhanced DCF Parameter Set is contained in a control packet sent by the AP to the associated stations, which contains class differentiated parameter values necessary to support the TCMA. These parameters can be changed based on different algorithms to support call admission and flow control functions and to meet the requirements of service level agreements.

    Abstract translation: 服务质量（QoS）支持通过分层竞争多路访问（TCMA）分布式媒体访问协议来提供，该协议根据其服务质量规范安排不同类型流量的传输。 在一个实施例中，从具有较低QoS优先级QoS（A）的源（例如文件传输数据）向无线站提供数据。 从具有较高QoS优先级QoS（B）的源（例如语音和视频数据）的源提供另一个无线站。 每个无线站可以根据调度算法确定其未决分组的紧急等级。 例如，文件传输数据被分配较低的紧急等级，并且语音和视频数据被分配更高的紧急等级。 有几个紧急级别表示所需的顺序。 在通过依赖类别分类的紧急仲裁时间（UAT），在随机退避计数器减少之前所需的空闲时间间隔的情况下，在发送较低紧急度类别的分组之前，发送给定紧急等级中的等待分组。 在另一个实施例中，分组被实时地重新分类为调度算法，该调度算法基于观察到的性能参数并根据协商的基于QoS的需求来调整分配给分组的类别。 此外，对于分配相同仲裁时间的分组，在所采用的争用解决机制方面实现了更加紧急等级的额外区分，从而产生混合分组优先级方法。 增强的DCF参数集包含在由AP发送到相关站的控制分组中，该组包含支持TCMA所需的类别差分参数值。 这些参数可以根据不同的算法进行更改，以支持呼叫准入和流量控制功能，并满足服务级别协议的要求。

    Abstract: An apparatus is equipped to receive network traffic data for network traffic routed through a number of routing devices with one or more degrees of separation from a network node. The network traffic data include at least network traffic data for network traffic destined for the network node which meet a traffic type selection criteria and are routed by the routing devices to the network node. The apparatus is further equipped to progressively regulate and de-regulate network traffic routing by the routing devices based at least in part on the received network traffic data and the degrees of separation of the routing devices from the network node. Regulation extends from routing devices with the highest degree of separation from the network node to routing devices with the lowest degree of separation from the network node to routing devices with the highest degree of separation, following in the reverse direction of the routing paths traversed by the packets to reach the network node. In one embodiment, the extension or push back is made one degree of separation at a time. In one embodiment, deregulation follows the reverse path, whereas in another embodiment, deregulation is determined and implemented locally, whenever regulation or the extent of regulation is no longer needed. In one embodiment, regulation is made in accordance with a not-to-exceed profile, and the not-to-exceed limit or limits are divided up as regulation extends away from the network node.

    Abstract: A communication system (10) includes a network (12) that is coupled to a number of terminals (22, 24, 26, 28, 30), at least some of which are capable of audio or other forms of real-time interactive data communications over the network (12). Each of the terminals (22, 24, 26, 28 and 30) includes a network adapter that is capable of detecting a collision with another terminal on the network (12). If a collision is detected, transmission of a data frame is aborted, and a backoff time delay is selected. The backoff time delay is selected from a group of delay periods that vary less than exponentially with a number of collisions.
