摘要： A router is disclosed for supporting local-level communication between separate subnets managed by different subnet managers. The router preferably makes one or more end nodes from one subnet “visible” to the subnet manager of another subnet. The end nodes may consequently be identified by one local identifier (LID) value in one subnet, but by another LID value in a different subnet. In a preferred embodiment, the router accepts from a first subnet local IB packets directed to end nodes made visible from a second subnet, and processes the local IB packet to convert the first subnet LID values for destination and source end nodes to second subnet LID values for these end nodes.

摘要： A system and method are disclosed for combining physically separate subnets of an Infiniband (IB) network into virtual subnets. In the virtual subnets, all of the end node in one subnet may be allowed to access all of the end nodes in another subnet, or the access may be limited to only a selected subset of another subnet. In addition to processing of globally-routed IB packets, the router also communicates (alone or in cooperation with another router) locally-routed IB packets traveling between a designated end nodes in different subnets. The routers may encapsulate the packets into raw datagrams for transport across intervening subnets. The described system and method may advantageously allow remote end nodes to act as a part of a given subnet, and may advantageously allow routers to provide both switch and routing functionality.

摘要： A multiport switch assembly comprises a plurality of discrete switch devices coupled together in a way that virtualizes the behavior of a multiport switch assembly. Each of said switch devices preferably has fewer ports than the number of ports made externally available by the multiport switch assembly. The multiport switch assembly preferably comprises a plurality of tiers of switch devices and a processor connected directly or indirectly to all or at least some of the switch devices. The processor executes code that permits the multiport switch assembly to appear, from the viewpoint of external logic (e.g., management entities, end nodes, routers, etc.), to operate as a single switch device. This alleviates the burden on the external logic, which otherwise would have to control each individual switch device to accomplish the desired switching behavior of the switch assembly.
摘要翻译：多端口开关组件包括以虚拟化多端口开关组件的行为的方式耦合在一起的多个离散开关装置。每个所述开关装置优选地具有比由多端口开关组件外部可用的端口的数量少的端口。多端口开关组件优选地包括多层开关装置和直接或间接地连接到所有或至少一些开关装置的处理器。从外部逻辑（例如，管理实体，终端节点，路由器等）的观点来看，处理器执行允许多端口交换机组件出现的代码，以用作单个交换设备。这减轻了外部逻辑的负担，否则将不得不控制每个单独的开关装置来实现开关组件的期望的开关行为。

摘要： An Infiniband (IB) router with an internal subnet architecture is disclosed. It comprises multiple port interface circuits interconnected by an internal IB subnet. The multiple port interface circuits each connect to an external IB subnet and preferably determine new local route headers (LRH) for global IB packets (i.e. packets having a global route header (GRH)). The new LRHs for externally received packets include a destination local identifier (DLID) value that identifies another port interface circuit in the router, whereas the new LRHs for internally received packets include a DLID value that identifies an end node or router in the external subnet to which the port interface circuit is attached. The internal IB subnet transports IB packets between the port interface circuits, directing them according to the contents of the LRHs. The internal subnet may take the form of an IB switch or a network of IB switches.
