Embodiment Construction

[0013] according to figure 1 , figure 2 As shown, a kind of unidirectional ring network controller described in the present invention includes a receiving port, a direct forwarding module, a sending port and an IFG timer, and also includes: a control state module, which controls the node to be in the listening mode or the sending mode, and is in the Busy state or idle state; forwarding switch, switch the forwarding line between the receiving port and the sending port, so that the receiving port and the sending port are connected through a forwarding line in direct forwarding, fast forwarding or store and forward; frame counter, record a certain The number of data frames actively sent by the node exists in the unidirectional ring network. In the present invention, the listening mode refers to the default basic mode of the node. The node cannot actively send data frames, but can receive data frames from the receiving port and simultaneously forward the data frames directly. S...

Abstract

The present invention discloses an unidirectional loop network controller. The controller comprises a receiving port, a direct connection forwarding module, a sending port and an IFG timer; and the controller also comprises a control state module configured to control a node to be located at a monitoring mode or the sending module or at a busy state or an idle state, a forwarding switching switch configured to switch a forwarding line between a receiving port and the sending port to forward line connection between the receiving port and the sending port through one of the direct connection forwarding, the fast forwarding or storage forwarding, and a frame timer configured to record the number of the data frames actively sent by one node in the unidirectional loop network. The unidirectional loop network controller solves the problem that the current unidirectional loop network cannot perform multi-frame forwarding at the same time, and provides cleaning and fault location of error data frames in the unidirectional loop network through the unidirectional loop network controller.

Description

technical field [0001] The present invention relates to a network controller, in particular to a one-way ring network controller and its usage method. Background technique [0002] Ethernet is a baseband local area network developed in the 1970s. After decades of development, it has become the most widely used local area network in the world today. Common LAN topologies include star, bus, and ring. At present, the most used physical topology structure in local area network is the star structure. Each node in the star network is connected to the central node through a super five twisted pair. The central node is the bottleneck of the entire network, and the failure of the central node will lead to the paralysis of the entire network. . The bus topology is to connect each node in the network with a bus (such as a coaxial cable) to realize the function of a computer network. Although this structure is simple to connect, it is difficult to maintain and troubleshoot, and prone ...
