Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] Refer to attached figure 1 , to further describe the present invention.

[0036] Step 1, the master node detects the port connection status.

[0037] The ring Ethernet master node detects the connection status of its own port. When the port link status changes from disconnected to connected, the protocol frame sending enable register of the port is set to valid, and the link initialization frame is formed and the link initialization frame is set. key field.

[0038] The steps for setting the key field of the link initialization frame are as follows:

[0039] In the first step, the ring Ethernet master node sets the source MAC address of the link initialization frame to 00-00-00-00-00-00, and sets the destination MAC address of the link initialization frame to FF -FF-FF-FF-FF-FF;

[0040] In the second step, the ring Ethernet master node sets the E...

Abstract

The invention discloses a load balancing pruning method of the loop Ethernet. The method is used for solving the problems that in a traditional loop Ethernet networking pruning method, network load shairing is ununiform, tail-end slave node data transmission delay is long. The method comprises the steps that 1, a master node detects the port connecting state; 2, a slave node sends a link initialization frame; 3, the difference of the distances between the slave node of the loop Ethernet and two ports of the master node of the loop Ethernet is acquired; 4, a redundant link is pruned; 5, a user accesses a network except the loop Ethernet. According to the method, the transmission capacity that the master node blocks the port is fully utilized, and network load balancing is achieved; the node blocking position is reasonably selected, and network delay generated when data of the tail-end slave node is introduced through the loop Ethernet is reduced.

Description

technical field [0001] The present invention relates to the technical field of communication, and further relates to a load balancing pruning method of a ring Ethernet in the technical field of network communication. The invention can be used to prevent service loops in the ring Ethernet, ensure the balanced transmission of uplink traffic on the link, and reduce the network delay introduced by terminal slave node data through the ring Ethernet. Background technique [0002] Ring Ethernet networking can provide network redundancy and improve network reliability, so it is widely used in industrial control. Ring Ethernet connects the nodes in the link end to end to form an Ethernet ring. The user configures one node on the Ethernet ring as the master node, and the other nodes as slave nodes. One port on the master node is designated as the master port. One port is designated as the slave port. After the system is powered on, the master node logically blocks the slave port, pr...
