Problems solved by technology

[0006] However, in the existing Ethernet automatic protection switching scheme, a large number of error messages are generated when the link is unstable or abnormal (may be in the up state), resulting in network instability

Embodiment Construction

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.

[0020] An EAPS method and system for realizing automatic switching by counting error messages disclosed by the present invention monitors the up and down states of the corresponding ports by counting the error message rate received by the port, and also monitors the state of the port receiving messages, To ensure the normal transmission of packets.

[0021] Such as figure 2 As shown, an EAPS system disclosed by an embodiment of the present invention realizes automatic switching by counting error messages, including a master node, three transmission nodes and links between nodes, the master node, transmission nodes and links are composed of In an EAPS ring, one of the two ports of the master node is the master port and the other is the auxiliary port. Under normal circumstances, tha...

Abstract

The invention discloses an EAPS method and system for achieving automatic switching through error message statistics. The method comprises the steps of conducting statistics of the number of error messages received by respective ports of all nodes on an EAPS loop within a specific statistic period, determining that the corresponding ports are abnormal if the statistical number exceeds a pre-configuration number and configuration time lasts, blocking a VLAN protected by a main port and meanwhile canceling auxiliary ports and blocking the protected VLAN when a main node detects that the main port is abnormal; blocking the protected VLAN at the corresponding abnormal port, sending warning information to the main node, informing the main node to start protection switching, canceling the auxiliary ports of the main node to block the protected VLAN and informing a transmission node to refresh forwarding tables of the ports when the transmission node detects that the port of the transmission node is abnormal. By means of the EAPS method and system, EAPS quick protection switching is achieved, normal message transmission is ensured, and accordingly the stability of links in a looped network and the stability of a corresponding network are improved.

Description

technical field [0001] The invention relates to the technical field of Ethernet ring network EAPS protocol, in particular to an EAPS method and system for realizing automatic switching by counting error messages. Background technique [0002] The Ethernet Ring Network EAPS (Ethernet Automatic Protection Switching, Ethernet Automatic Protection Switching) protocol is an Ethernet Automatic Protection Switching solution released by the Internet Engineering Task Force (IETF) in 2003 and has great influence. The protection domain of EAPS is limited to a ring network. The working principle of this technology is: on the physical ring network composed of Ethernet nodes and links, several domains (Domains) can be created, and each domain controls a group of VLANs (Virtual VLANs). Local Area Network (Virtual Local Area Network) protection switching of business traffic, the domain is composed of a control VLAN (Control VLAN) and a group of protected VLANs (Protected VLAN), the control ...
