摘要： Network units such as switches for use in a cascaded stack are organised to provide a cascade connection in the form of a dual unidirectional connection so that, in its ordinary configuration, there is at least one and preferably more than one unidirectional ring for each direction around the cascade, each ring including a respective port on each unit. For each ring, each port on a unit is connected by a respective link to a corresponding port on the preceding unit and the following unit. The units provide a self-healing operation in the event of various kinds of operational failure. The self-healing operation includes loop-back of packets in units adjacent the failure and bypass of a packet switching process for other units. The units include control logic for passing control frames containing status information relating to the units and links between them and for co-operation with a CPU to control a switching engine to perform the self-healing operation in accordance with that status information. The units forward on the cascade packets with headers that identify a destination port and the unit on which that port is located and also indicate which units have and have not been traversed by a packet.

摘要： In one embodiment, a method is described for detecting an operational failure between the network unit and an adjacent network unit in the stack; controlling the switching engine to redirect packets which would otherwise be sent from a particular port to the adjacent network unit to be forwarded from another port to be sent to a different network unit in the stack; and entering the switching engine into a bypass mode in response to control data indicating an operational failure between at least two other network units in the stack to cause packets to be forwarded without being re-directed by the switching engine.

摘要： A data processor and storage system which comprises a data processor, a cache memory and a main memory is arranged so that the addressing of the main memory produces a multiplicity of spaced aliases, the multiplicity being greater than the set-associativity of the cache memory. The cache memory may be a multiple way set associative cache memory with the system including a round robin allocator for controlling the storing of successive data items in the different ways of the set associative cache. The cache may also be a direct mapped cache having single way set-associativity so that the round robin allocator is not required. The system may also include a direct memory access (DMA) device for copying data items into the memory. The memory may be a buffer memory which is divided into a plurality of packet buffers.

摘要： Cascade control logic for use in a switch or other network unit that can be used in a cascaded stack can maintain normally a point-to-point half-duplex connection for control data with each of the next preceding and next succeeding units in the cascade. Each cascade logic device is organised so that for one direction, conveniently called the up direction, a device is a master and in the other direction the device is a slave in respect of the control path. A control device will generate master control frames in the up direction and deliver slave control frames in the down direction. The control device is organised so that in the absence of reception of valid control frames on a control link control data which would otherwise be sent out on that link is looped back within the control device. In this manner the control device can maintain under normal circumstances two virtual control channels which can ‘self-heal’ notwithstanding the failure or powering-down of a unit in the cascade.Status information represented by the control frames can be used to control a switching engine to provide self healing of the data path in the cascade.
摘要翻译：用于在级联堆叠中使用的交换机或其他网络单元中的级联控制逻辑可以正常地维护级联中的下一个前一个和后续单元中的每一个的控制数据的点对点半双工连接。每个级联逻辑器件被组织成使得对于一个方向，方便地称为向上方向，器件是主器件，并且在另一方向上，器件是关于控制路径的从器件。控制装置将沿向上方向产生主控制帧，并向下传送从控制帧。控制装置被组织成使得在没有接收到控制链路上的有效控制帧的情况下，否则将在该链路上发送的控制数据环回到控制装置内。以这种方式，控制装置可以在正常情况下维持两个虚拟控制通道，即使在级联中的单元发生故障或断电，它们也可“自愈”。由控制帧表示的状态信息可用于控制切换引擎以提供级联中的数据路径的自愈。

摘要： A network device which includes means for receiving data packets over a link, a memory for the packets, means for providing an indication that the occupancy of the memory is less than a first watermark, and means responsive to the indication for providing a sequence of pause frames comprising an alternating sequence of XOFF frames defining a very long cessation of the sending of packets and XON frames defining substantially zero cessation of the sending of packets. The means for providing the pause frames is responsive to the increase of the occupancy of the memory above a selected watermark to cease the provision of the sequence of pause frames.
