Problems solved by technology

[0006] In order to solve the problem in the prior art, the automatic protection switching method of SDH is only applicable to the optical network, and the protection of Ethernet cannot be realized in the hybrid network of SDH and Ethernet, and the automatic protection switching of SDH needs the equipment to support the APS feature. Complicated shortcoming, the present invention proposes a kind of active equipment to transmit the method that switchover alarm signal and VRRP protection group monitor active SDH interface state, described method comprises the following steps:

Embodiment 1

[0037] Referring to Figure 1 and Figure 2, if the active transmission optical path between the active equipment and transmission equipment A fails, in order not to interrupt the service or quickly restore the service after the interruption, it is necessary to perform service protection switching, and the active transmission optical path appears The fault is the failure of the active transmission optical path from transmission equipment A to the active equipment. The specific steps for service protection switching are as follows:

[0038] Step 101: Since the main transmission optical path from the transmission equipment A to the main equipment fails, the main equipment does not receive the optical signal. Since the present invention configures the function of sending switching alarm signals of the main equipment, the main equipment will When no optical signal is received, a switching alarm signal, such as LOF, LOS, MS-AIS, and MS-EXC, is sent to transmission equipment A. The tr...

Embodiment 2

[0041] Referring to Figure 1 and Figure 3, if the active transmission optical path between the active equipment and transmission equipment A fails, in order not to interrupt the service or quickly restore the service after the interruption, it is necessary to perform service protection switching, and the active transmission optical path appears The main transmission optical path from the active equipment to transmission equipment A is faulty, and the specific steps for service protection switching are as follows:

[0042] Step 201: Since the main transmission optical path from the master device to the transmission device A fails, the transmission device A does not receive the optical signal, and the transmission device A does not receive the optical signal, so the protection switching is performed, and the direction from SDH to Ethernet The traffic is switched to the standby device for sending.

[0043] Step 202: Since the VRRP protection group monitors that the state of the a...

Embodiment 3

[0046] Referring to Figure 1 and Figure 4, the active transmission optical path is normal. When the active VRRP is reduced to the standby state, the traffic in both directions between SDH and Ethernet will be switched to the standby equipment for transmission. The specific steps for this are as follows:

[0047] Step 301: When the active VRRP is reduced to the standby state, since the present invention configures the function of sending the switching alarm signal of the active equipment, the active equipment sends a switching alarm signal to the transmission equipment A, such as LOF, LOS, MS-AIS, MS- EXC, transmission equipment A receives the switching alarm signal, performs protection switching, and switches the traffic from SDH to Ethernet to the standby equipment for transmission.

[0048] Step 302: The backup device becomes the active VRRP device, and the traffic in the direction from Ethernet to SDH is switched to the backup device for transmission.

[0049] In this way, ...

Abstract

The invention discloses a mixed networking protecting method and device, belonging to network management field. And the invention advances a method that a master device sends switching alarm signal and VRRP protection group to a transmitter to monitor master SDH interface status, implementing SDH network protection and Ethernet protection. And the invention also provides a mixed networking protecting device, for implementing SDH network and Ethernet protection.

Description

technical field [0001] The invention relates to the field of network management, in particular to a protection method and device for hybrid networking. Background technique [0002] Automatic Protection Switching (APS-Automatic Protection Switching) of SDH (Synchronous Digital Hierarchy-Synchronous Digital System) network is a redundant protection mechanism defined by ITU G.783 and G.841, including multiplex section shared protection ring, Multiplex section dedicated line protection ring, linear multiplex section protection and other types. [0003] The multiplex section protection is to detect the optical fiber and equipment operation at each end of the multiplex section. The node sends out a protection switching request, and the opposite end gives a protection switching mechanism to switch the bridging response. The multiplex section protection switching mechanism is divided into two modes: 1:N and 1+1. In the 1:N mode, N service channels share one protection channel, an...
