Embodiment Construction

[0052]In order to solve the problem of unnecessary network failures caused by manual adjustment of CCI speed in the prior art, the present invention provides a method for synchronizing message sending time intervals, and the same maintenance domain and maintenance set are performed by sending and receiving CCI synchronization messages. CCI adjustments. The user configures a new CCI for an initial device in the maintenance domain and maintenance set. The initial device uses the original CCI to send a CCI synchronization message carrying the new CCI. The CCI synchronization message also carries the information of the maintenance domain and the maintenance set. Identification information. The device that receives the CCI synchronization message updates the local CCI according to the identification information of the maintenance domain and maintenance set carried in the CCI synchronization message and the new CCI, so as to realize the rapid adjustment of the unified maintenance do...

Abstract

The invention discloses a method and a device for synchronizing packet sending intervals. The method includes that the device receives the CCI synchronous packet communicating sending time intervals of detection packets in the maintenance domain and the maintenance collection where the device is located, wherein the CCI synchronous packet includes marks of maintenance region and maintenance collection and novel CCI; the device determines whether to update the local CCI based on marks of maintenance region and maintenance collection carried by the CCI synchronous packet and novel CCI; if the determination result is to update, the device updates the local CCI to the novel CCI, and sends CCI synchronous packets and communicating detection packet using the novel CCI to other devices in the maintenance region and the maintenance collection. According to the invention, the device in the maintenance region and the maintenance collection rapidly regulates CCI of all devices in the maintenance region and the maintenance collection by transceiving CCI synchronous packets carrying novel CCI, thereby enhances speed and efficiency of CCI regulation.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and device for synchronizing message sending time intervals. Background technique [0002] The success of Ethernet technology in the field of LAN, as well as its advantages of simple deployment and maintenance, have prompted service providers, equipment manufacturers and standardization organizations to advance Ethernet technology to the field of MAN and WAN. However, the main obstacle facing the entry of Ethernet technology into the carrier field is the lack of effective maintenance and management tools, so Connectivity Fault Management (CFM, Connectivity Fault Management) came into being. [0003] CFM provides end-to-end connectivity detection. It mainly performs layered link monitoring and fault detection on Layer 2 interconnection services provided by operators. It mainly includes three functions: connectivity detection (CC, ConnectivityCheck), loopback (LB, Loop Back) and...
