The management control system based on the new forwarding network provides the following embodiments of the present invention.

The embodiment of the invention provides an information processing method based on a new forwarding network. Fig. 2 is a flow chart of a new forwarding network-based information processing method according to an embodiment of the present invention; as shown in fig. 2, the method includes:

step 101: the first optical module receives OAM information of a second optical module from the second optical module; the OAM information of the second optical module reaches the first optical module through the second WDM equipment and the first WDM equipment;

step 102: the first optical module resends OAM information of the second optical module to the second optical module; the retransmitted OAM information of the second optical module reaches the second optical module through the first WDM equipment and the second WDM equipment.

In this embodiment, the OAM information (including OAM information of the second optical module) transmitted between the first optical module and the second optical module is transmitted through optical signals. The OAM information (including OAM information of the second optical module) may include at least one of the following information: port information and alarm information. Wherein the alert information may include at least one of the following: voltage value, current value, power value, LOSs Of Signal (LOS), etc.; the LOS is an alarm signal which appears when the receiving end cannot receive the signal transmitted by the sending end. Of course, the OAM information in the present embodiment is not limited to the above information, and other information capable of indicating the state of the optical module or other types of alarm information may be within the protection scope of the present embodiment. Illustratively, the OAM information of the second optical module may include at least one of port information of the second optical module and alarm information of the second optical module.

In this embodiment, the first WDM device is an active WDM device, and the second WDM device is a passive WDM device; alternatively, the first WDM device is a passive WDM device and the second WDM device is an active WDM device.

It will be appreciated that the first optical module is deployed in a position adjacent to the first WDM equipment and the second optical module is deployed in a position adjacent to the second WDM equipment. In one scenario, a first optical module is proximate a first WDM device that is an active WDM device and a second optical module is proximate a second WDM device that is a passive WDM device; in another scenario, a first optical module is proximate a first WDM device that is a passive WDM device and a second optical module is proximate a second WDM device that is an active WDM device. That is, the optical modules (including the first optical module and the second optical module) in this embodiment may both transmit OAM information and receive OAM information.

In one embodiment, the first optical module may be an optical module in proximity to an active WDM device and the second optical module may be an optical module in proximity to a passive WDM device, i.e. the first WDM device is an active WDM device and the second WDM device is a passive WDM device. Taking the example shown in fig. 1, the first WDM device 11 is an active WDM device, the second WDM device 12 is a passive WDM device, and the first optical module is an optical module disposed at the first communication node 13, and the second optical module is an optical module disposed at the second communication node 14.

In this embodiment, in the active WDM apparatus of the first WDM apparatus or the second WDM apparatus, a detection module (such as a PD device) is provided on the first link for the optical module, respectively. Wherein the transmission direction of the first link is the transmission direction of an optical module associated with an active WDM device to the active WDM device. Taking the example shown in fig. 1, the first link is a transmission link from the optical module 15 provided at the first communication node 13 to the first WDM device 11 as an active WDM device.

In this embodiment, the detection module in the active WDM apparatus may acquire OAM information transmitted on the first link. Referring to the example shown in fig. 1, taking the second optical module as an optical module disposed in the second communication node 14, the first optical module as an optical module disposed in the first communication node 13, and the first WDM device 11 as an active WDM device, and the first detection module is disposed for the first link of the first optical module, if on the one hand, the first optical module sends its own OAM information (i.e., the OAM information of the first optical module) to the second optical module, the first WDM device 11 forwards the OAM information of the first optical module to the second WDM device, and the second WDM device sends the OAM information to the corresponding optical module (assumed to be the second optical module) disposed in the second communication node; the first WDM equipment 11 may obtain OAM information of the first optical module through a first detection module; on the other hand, in the case where the second optical module transmits its own OAM information (i.e., OAM information of the second optical module) to the first optical module, the second WDM apparatus 12 and the first WDM apparatus 11 forward OAM of the second optical module, respectively, so that the first optical module receives the OAM information of the second optical module and resends the OAM information of the second optical module to the second optical module; the retransmitted OAM information of the second optical module reaches the second optical module through the first WDM equipment 11 and the second WDM equipment 12; in the process of forwarding the retransmitted OAM information of the second optical module by the first WDM equipment 11, the first WDM equipment 11 may obtain the OAM information of the second optical module through the first detection module.

In this way, on the one hand, through the detection component correspondingly arranged for the first link of each optical module in the active WDM equipment, the OAM information sent by the corresponding optical module can be obtained, and the OAM information from the opposite-end optical module can also be repeatedly sent by the optical module, so that the corresponding detection component can also obtain the OAM information from the opposite-end optical module, thereby greatly reducing the number of required detection modules and simplifying the system implementation.

On the other hand, OAM information transmitted by the opposite optical module, for example, OAM information transmitted by the optical module provided at the second communication node 14 shown in fig. 1 to the optical module provided at the first communication node 13, may be attenuated (the optical signal passing through the optical splitter is weak) after passing through the first WDM equipment 11 through a long path transmission. If the OAM information transmitted on the second link is obtained by the detection module provided on the second link (the second link may be a transmission link from the first WDM device 11, which is an active WDM device, to the optical module 15 provided on the first communication node 13) in the related art, there may occur a case where information is not obtained due to weak optical signals. In order to avoid the occurrence of the above situation, in the embodiment of the present invention, the detection component set on the first link obtains the OAM information transmitted on the first link, so that OAM information directly sent by the optical module set on the first communication node 13 may be obtained, the signal strength is relatively strong, and the situation that the information cannot be obtained due to weak optical signal does not occur.

In some optional embodiments of the present invention, the first optical module receives OAM information from a second optical module sent by the second optical module, including: the first optical module receives an OAM message from the second optical module, wherein the OAM message uses a first specific field for indicating OAM information of the second optical module; the first optical module resends the OAM information of the second optical module to the second optical module, including: and the first optical module resends the OAM message to the second optical module.

In this embodiment, the OAM information transmitted between the first optical module and the second optical module may be transmitted through an OAM message. The system shown in fig. 1 may also be referred to as an open WDM (OpenWDM) system, and the OAM message described above may also be referred to as an OpenWDM OAM message (OpenWDM OAM Message).

Table 1 is an example of an OAM message format, as shown in table 1, an OAM message may include fields shown in the first row of table 1; wherein, the message type field in the OAM message is used for indicating that the message is an OAM message; the OAM information is carried in a message content field in the OAM message; illustratively, the message content field in the OAM message includes at least one of port information and alarm information. After receiving the OAM message carrying the OAM information of the second optical module, the first optical module directly transmits the OAM message without changing any content in the message, i.e., repeatedly sends the OAM message to the second optical module.

TABLE 1

In some optional embodiments of the present invention, the first optical module resends OAM information of the second optical module to the second optical module, including: the first optical module identifies a module identifier in an OAM message; judging whether the module identifier is consistent with the module identifier of the first optical module; and retransmitting the OAM message to the second optical module, namely retransmitting the OAM information of the second optical module to the second optical module under the condition that the module identification is inconsistent with the module identification of the first optical module.

In this embodiment, the first optical module may determine which optical module the corresponding OAM message is sent out based on the module ID field in the OAM message; and under the condition that the OAM message is determined to be the OAM message from the second optical module, namely, the OAM message is determined not to be the OAM message which is sent by the first optical module and carries the OAM information of the first optical module, the first optical module directly reflects (resends) the OAM message to the second optical module.

Based on the foregoing embodiment, the embodiment of the present invention further provides an information processing method based on the new forwarding network.

step 202: the second optical module receives OAM information of the second optical module from the first optical module, and does not process the retransmitted OAM information of the second optical module; wherein the retransmitted OAM information of the second optical module arrives at the second optical module via the first WDM device and the second WDM device.

In this embodiment, the OAM information (including OAM information of the second optical module) may include at least one of the following information: port information and alarm information. Wherein the alert information may include at least one of the following: voltage value, current value, power value, LOSs Of Signal (LOS), etc.; the LOS is an alarm signal which appears when the receiving end cannot receive the signal transmitted by the sending end. Of course, the OAM information in the present embodiment is not limited to the above information, and other information capable of indicating the state of the optical module or other types of alarm information may be within the protection scope of the present embodiment.

In this embodiment, after receiving the OAM message, the second optical module identifies a module ID field in the OAM message; if the module ID in the module ID field is identified as the self ID (the module ID of the second optical module), it may indicate that the received OAM message is the OAM message that the first optical module repeatedly transmits, and the second optical module does not perform any processing on such OAM message.

In another case, the second optical module 152 may obtain its own OAM information (i.e., OAM information of the second optical module), and send out the OAM information; the OAM message may reach the first optical module 151 via the second WDM device 12, the first WDM device 11; the first optical module 151 may determine that the module ID in the module ID field is not the module ID of itself by identifying the module ID field in the OAM message, and further reflect the OAM message, that is, resend the OAM message to the second optical module; during or before forwarding an OAM message by the first WDM equipment 11, the first WDM equipment 11 may obtain the OAM message by using a PD, thereby obtaining OAM information of the second optical module carried in the OAM message; the OAM information of the second optical module may be further sent to a management and control system.

Further, the OAM message arrives at the second optical module 152 via the forwarding of the first WDM equipment 11 and the second WDM equipment 12. The second optical module 152 determines that the module ID in the module ID field is the module ID of the second optical module 152 itself by identifying the module ID field in the OAM message, and the second optical module 152 does not perform any processing on the OAM message.

On the other hand, OAM information transmitted by the opposite optical module, for example, OAM information provided at the second communication node 14 and transmitted to the optical module provided at the first communication node 13 shown in fig. 1, may be attenuated (the optical signal passing through the optical splitter is weak) after passing through the first WDM apparatus 11 through a longer path transmission. If the OAM information transmitted on the second link is obtained by the detection module provided on the second link (the second link may be a transmission link from the first WDM device 11, which is an active WDM device, to the optical module 15 provided on the first communication node 13) in the related art, there may occur a case where information is not obtained due to weak optical signals. In order to avoid the occurrence of the above situation, in the embodiment of the present invention, the detection component set on the first link obtains the OAM information transmitted on the first link, so that OAM information directly sent by the optical module set on the first communication node 13 may be obtained, the signal strength is relatively strong, and the situation that the information cannot be obtained due to weak optical signal does not occur.
