Embodiment Construction

[0033] In view of the problems mentioned in the background technology, the embodiment of the present invention proposes: when the user-side link fails, generate user-side link failure information indicating that the user-side link fails, and based on the network connected to the user-side link The side link sends the failure information of the user-side link, thereby achieving the purpose of timely notifying the user-side link failure and improving the effectiveness of failure notification.

[0034] Both ends of the network-side link can be connected to one or more user-side links, wherein the user-side link connected to one end is the user-side link of the service sending end, and the user-side link connected to the other end is the user-side link of the service receiving end. user-side link.

[0035]When the user-side link of the service sending end fails, based on the network-side link, the user-side link connected to the service sending end and the equipment connected to t...

Abstract

The invention discloses a failure informing method and device to enhance the effectiveness of failure informing. The method comprises: user side chain link failure information is produced when the failure of the user side chain link of conveying operation is monitored; the user side chain link failure information is sent through a network side chain link, which is connected with the user side chain link. The prevent invention also discloses an operation receiving method and device to ensure the successful conveying of the operation. The method comprises: the user side link failure informationis received; according to the received user side link failure information, the operation is received by switching to the link of the normal user side link of an operation sending terminal.

Description

technical field [0001] The present invention relates to the service transfer technology in the communication field, in particular to a fault notification method and device, and a service receiving method and device. Background technique [0002] With the large-scale application of Ethernet technology in networks such as enterprise networks, metropolitan area networks, and wide area networks, the shortcomings of traditional Ethernet, such as maintainability and weak operability, have gradually become apparent. Protection has increasingly become the focus of the industry. [0003] figure 1 It is a schematic diagram of a scenario where a user-side device is dual-homed to access the network side. In the figure, user-side (CE, Customer Edge) device 1 is connected to network-side (PE, Provider Edge) device 1, PE3, PE1 and PE3 is connected to PE2 through the primary tunnel and the backup tunnel respectively. The tunnel is a MAC in MAC tunnel, which is a network-side link with ...
