A network control device that implements routing functions based on multi-network port end drivers

Abstract

The present invention is a network control device based on multi-network port END drive to realize the routing function, including a circuit part 1, a panel part 2, a rear cover part 3, a housing part 4 and an upper cover part 5, and the circuit part 1 Placed in the housing part 4, together with the front panel part 2, the rear rear cover 3 and the upper cover 5, they are combined to form a whole. The BCM three-layer switching module is adopted, with the core module as the center, and the application module handles protocol interaction with external devices; the routing module handles dynamic and static networking, and network topology maintenance functions; the END driver implements 24 external Ethernet interfaces ; The BCM driver completes the control function of the kernel module on the switch module. Provide network switching modules, data processing modules, Ethernet interface indicators, etc., and support the access of 24-way layer 2 and layer 3 switching devices. It has the characteristics of reasonable design, fast switching, flexible topology, multiple access points, reliable work, convenient installation, and simple operation.

Description

technical field [0001] The invention relates to a network control device for realizing the routing function, in particular to a network control device for realizing the routing function based on the multi-network port END drive technology. Background technique [0002] Vxworks is a high-performance real-time operating system widely used at present. It has superior network performance and integrates TCP / IP network protocol stack and END-type network driver. [0003] However, the original network driver of the Vxworks system can only load up to 4 network port END drivers, which cannot meet the requirements of multi-network port (port) networking applications of devices; at the same time, according to the actual network application environment, the network architecture of multi-device and multi-port is very complicated , the need to transmit data across network topology levels has also become a major technical difficulty. [0004] Therefore, how to load up to 24 network port E...
