Abstract: The present disclosure relates to a routing switch apparatus, a network switch system, and a routing switch method. The routing switch apparatus includes one or more direct memory access modules and at least two protocol conversion interfaces. The direct memory access module is configured to generate a continuous access request of a cross network node, and control data transmission in the at least two protocol conversion interfaces; each protocol conversion interface is configured to convert a communication protocol of data transmitted inside and outside the routing switch apparatus and connect the routing switch module and an external network node. The routing switch apparatus may be introduced to replace a network switch, so that cross-node memory access and IO space access can be performed directly rather than through a proxy, thereby reducing delay of the cross-node memory access and IO space access and improving overall performance of a system.

Abstract: Embodiments of the present disclosure relate to a method and a device for enumerating input/output devices (IO devices). The method for enumerating input/output devices includes: acquiring an identifier of each processor and an identifier of each input/output (IO) centralized controller in a system; separately instructing processors to simultaneously enumerate a specific IO centralized controller and an input/output IO device connected to the specific IO centralized controller, according to the identifier of each processor and the identifier of each IO centralized controller; and acquiring related information of IO devices enumerated by the instructed processors. According to the embodiments of the present disclosure, the work of enumerating the system IO devices may be allocated to multiple processors to be carried out simultaneously, so as to greatly reduce time consumed in the enumeration process, and to accelerate a system initialization process.
