    • PROBLEM TO BE SOLVED: To provide a switch device in which a plurality of switch devices having different storing conditions can be connected to constitute a switch stack, relating to such switch device as a plurality of switch devices can be connected each other to be allowed to operate as a single switch (switch stack) which can be logically maintained and operated.SOLUTION: A stackable switch device which operates in any one of two following modes is provided, for an operation reference of a switch device that takes a role of a master/backup: 1. the master/backup bears only a plurality of switch devices or the one having the largest storing condition, and if a switch failure of the master/backup or the like results in communication unavailability and no alternatives to the switch device having the largest storing condition is available, a switch stack is considered to be down; and 2. operation is made in accordance with the switching device having the smallest storing condition among all switching devices constituting the switch stack.

    • PROBLEM TO BE SOLVED: To transfer a configuration request transmitted from a programmable device to a controller, and to save memory resources by extracting configuration information from a memory subsystem by the controller to transfer the extracted configuration information to the programmable device of the requestor. SOLUTION: A broadcast router includes a plurality of input cards, first and second router matrix cards and a plurality of output cards. A programmable device located on the card requiring configuration issues a configuration request to a main controller which is present with a shared configuration information repository. After a period of time which allows additional programmable devices to request configuration elapses, the main controller polls the programmable devices located on the cards to determine which of the programmable devices have requested configuration and, using the configuration information maintained in the shared configuration information repository, configures each programmable device which have requested configuration.

    • 要解决的问题:将从可编程设备发送的配置请求传送到控制器,并且通过由控制器从存储器子系统提取配置信息来节省存储器资源,以将提取的配置信息传送到可编程设备的可编程设备 请求者。 解决方案:广播路由器包括多个输入卡,第一和第二路由器矩阵卡和多个输出卡。 位于卡上的可编程设备需要配置向具有共享配置信息库的主控制器发出配置请求。 在允许附加可编程设备请求配置过去一段时间之后,主控制器轮询位于卡上的可编程设备,以确定哪些可编程设备已经请求配置,并且使用维护在共享配置信息库中的配置信息, 配置要求配置的每个可编程设备。 版权所有(C)2010,JPO&INPIT
