Embodiment Construction

[0022] 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 in conjunction with specific implementation methods and accompanying drawings. Here, the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0023] In the embodiment of the present invention, the standby link of the standby board is connected to the main board through the inter-board high-speed serial channel of the ATM interface board, and the main and standby links are bound into an IMA group by using the IMA protocol, so as to realize the load sharing Transmission backup, improve bandwidth utilization, transmission reliability and transmission efficiency.

[0024] Such as figure 2 Shown is a structural diagram of a link data protection system provided by an embodiment of the present invention. The data link prot...

Abstract

The embodiment of the invention provides a protection method a system and a device of link data. The method includes the steps of configuring a main and standby link of a main interface board and a standby interface board; connecting the standby link of the standby interface board to the main interface board through a high-speed serial channel among plates; and binding the main and standby link into an IMA group in the main interface board. By binding the main and standby link into one IMA group logically and transmitting business data in a load sharing manner of the main and standby link, the embodiment improves the bandwidth utilization rate of a transmission link and consequently reduces the waste of transmission resources. According to the property of IMA protocol, when a link is disconnected, other links can still be in an activated status, thus not interrupting user data, guaranteeing the smoothness of business and improving the reliability of transmission.

Description

technical field [0001] The invention relates to the field of transmission, in particular to the data transmission of the ATM network, in particular to a method, system and device for protecting link data. Background technique [0002] At present, the protection of data transmission in the ATM network usually adopts the mode of active and standby interface board backup. Taking the Base Station Sub-System (BSS) in wireless communication as an example, the traditional wireless BSS network interface backup Design framework such as figure 1 As shown, the base transceiver station (Base Transceiver Station, BTS) and the base station controller (Base Station Controller, BSC) asynchronous transfer mode (Asynchronous Transfer Mode, ATM) interface boards all use the mode of active and standby board backup to maintain the service chain The road is protected. The ATM interface single board can complete all processing from the physical layer to the transmission convergence sublayer (TC ...
