摘要： Methods for transfer of bulk data from a leader device to a follower device over a bus are described. The methods employ address frames and write frames. The bus, the address frames, and the write frames are compatible with Clause 45 of IEEE Std 802.3-2015. The methods achieve a reduction in the number of frames employed to transfer data as contrasted with conventional indirect write transactions. After transmitting on a Management Data Input/Output (MDIO) data signal an address frame that specifies the follower device and that contains the address of an initial register, the leader device proceeds to transmit on the MDIO data signal multiple write frames that specify the target follower device, the multiple write frames transmitted one at a time, each write frame containing a different block of the bulk data. A follower device implements a post-write-increment-address action, despite the absence of any definition in Clause 45 of IEEE Std 802.3-2015 of a post-write-increment-address frame.

摘要： A method and system for conveying an arbitrary mixture of high and low latency traffic streams across a common switch fabric implements a multi-dimensional traffic classification scheme, in which multiple orthogonal traffic classification methods are successively implemented for each traffic stream traversing the system. At least two diverse paths are mapped through the switch fabric, each path being optimized to satisfy respective different latency requirements. A latency classifier is adapted to route each traffic stream to a selected path optimized to satisfy latency requirements most closely matching a respective latency requirement of the traffic stream. A prioritization classifier independently prioritizes traffic streams in each path. A fairness classifier at an egress of each path can be used to enforce fairness between responsive and non-responsive traffic streams in each path. This arrangement enables traffic streams having similar latency requirements to traverse the system through a path optimized for those latency requirements.

摘要翻译： 用于传送跨越公共交换机结构的高延迟和低等待时间业务流的任意混合的方法和系统实现多维业务分类方案，其中对于遍历系统的每个业务流连续地实现多个正交业务分类方法。 通过交换结构映射至少两个不同的路径，每个路径被优化以满足各自的不同等待时间要求。 延迟分类器适于将每个业务流路由到经过优化的所选路径，以满足与业务流的相应等待时间要求最接近的等待时间要求。 优先级分类器在每个路径中独立地对流量进行优先级排序。 每个路径的出口处的公平分类器可以用于在每个路径中的响应和非响应业务流之间实施公平性。 这种布置使得具有相似等待时间要求的业务流可以通过针对那些等待时间要求而优化的路径来遍历系统。
