摘要： A network device for interconnecting computer networks, the device including a bridge having a plurality of ports through which network communications pass to and from the bridge, the bridge also including a first interface enabling a user to partition the plurality of bridge ports into a plurality of groups, wherein each group represents a different virtual network, wherein the bridge treats all ports within a given group as part of the virtual network corresponding to that group and the bridge isolates the virtual networks from each other, whereby any communications received at a first port of the bridge are directly sent by the bridge to another bridge port only if the other bridge port and the first bridge port are part of the same group.

摘要： A mechanism for operating a configurable switch to dynamically (i) route each of the data packets in an ordered string from a particular switch input port through a selected member output port of a hunt group; and (ii) route data packets which need not be transmitted in order from the input ports to available member output ports of the hunt group, as the members become available. A controller assigns each input port a service number, and directs member output ports to handle requests for ordered data packet transmissions from input ports with particular service numbers, such that the ordered transfers from an input port are handled by a single member of each group. The input port broadcasts, through the switch, a request to send ordered data packets through a particular hunt group and includes its service number in the request. The group member assigned to handle ordered transfers from the input port responds by identifying itself. Thereafter, the input port sends its ordered data packets to the identified member. Unordered data packets are queued and routed dynamically through the members of the group, as the members become available. In a local area network, data is sent from a source station to file servers using server group identifiers for multiple-route transfers or individual server identifiers for single-route transfers.
摘要翻译：一种用于操作可配置交换机的机制，用于动态地（i）将来自特定交换机输入端口的有序字符串中的每个数据分组路由到寻线组的所选成员输出端口; 以及（ii）当成员变得可用时，将从搜索组的输入端口到可用成员输出端口的顺序的数据包路由不需要传送。控制器为每个输入端口分配服务号码，并指示成员输出端口处理来自具有特定服务号码的输入端口的有序数据分组传输的请求，使得来自输入端口的有序传输由每个组的单个成员处理。输入端口通过交换机广播通过特定寻线组发送有序数据包的请求，并在请求中包括其服务号码。分配给处理来自输入端口的有序传输的组成员通过识别自身进行响应。此后，输入端口向已识别的成员发送其有序数据包。随着成员可用，无序数据包将通过组的成员进行排队和路由。在局域网中，使用用于多路由传输的服务器组标识符或单路传输的单个服务器标识符将数据从源站发送到文件服务器。

摘要： A method for improving modal bandwidth in computer networks using multimode optical fiber and laser sources is disclosed in which an annular beam is generate by the laser source, thus preventing center fiber transmission modes from reaching the detector. This prevents or lessens a pulse-splitting effect at the detector. The annular beam is generated preferably by configuring a vertical cavity surface emitting laser to have a center totally-reflecting block of 5-7 microns to generate a substantially dark-centered beam.
