Problems solved by technology

According to the forwarding principle of Ethernet equipment, any Ethernet data frame will be forwarded cyclically on the above-mentioned closed loop, so that the cycle of data frame forwarding occurs on the ring, and the site equipment receives a large number of repeated frames, which eventually leads to the unavailability of the network

Embodiment Construction

[0060] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0061] In the present invention, a master ring is selected in advance from at least two EAPS rings contained in a certain EAPS tangent ring, and the remaining EAPS rings are determined as slave rings, and the above setting results are saved on all intersecting sites of the EAPS tangent rings , there can only be one main ring in each EAPS tangent ring.

[0062] There are many ways to set the master ring and slave ring on the intersecting site. For example, the master ring and the slave ring can be distinguished by setting the order of sending messages. First, the alarm message is sent to the master site of the master ring, and then the fault shielding message is sent to all slave rings. The main site of the ring, and save the above message sending order ...

Abstract

The method includes following steps: a master ring is selected from more than two EAPS rings contained by EAPS intersecting rings; there is a main station in the master ring; other EAPS rings are defined as slave rings; there is a main station in each slave ring; the setting results above are saved in each station at intersecting point on the EAPS intersecting rings; after the stations at intersecting point detects a fault on sharing route, it transmits alarm notice to the main station on the master ring and the stations on slave rings; after receiving the alarm notice, the main station on master ring makes protection switching, and the slave station makes self shielding for not making protection switching.

Description

technical field [0001] The invention relates to network protection technology, in particular to a fault processing method for tangent rings of an Ethernet automatic protection system. Background technique [0002] The Ethernet Automatic Protect System (EAPS) ring is a commonly used network protection technology. Multiple sites are connected to each other to form an EAPS ring. There is only one master site on the ring, and the rest are slave sites. There are service VLANs for sending service data and control VLANs for sending control messages on the EAPS ring. For the service VLANs, the primary site blocks one of its own physical ports. [0003] Fig. 1(a) shows the basic composition of the EAPS ring. There is a master station M and three slave stations T1, T2 and T3 on the EAPS ring. Under normal circumstances, the EAPS ring is in the initial state, and the standby port of the main site M is blocked, which is indicated by the gray circle in Figure 1(a). At this time, the li...
