Before describing the management method of the intermediate device provided by the embodiment of the present application in detail, the implementation environment and application field Jing Jinhang of the embodiment of the present application are described.

First, an application scenario of the embodiment of the present application is described.

In recent years, with the development of optical fiber communication technology, the optical service unit (optical service unit, OSU) technology has grown in the face of the demand of new services such as private lines, video, etc. for flexible bandwidth bearers. On the premise of keeping the advantages of a traditional optical transport network (optical transport network, OTN) hard pipeline, rich operation maintenance management (operation administration and maintenance, OAM) and the like, an OSU technology introduces a flexible optical service unit (optical service unit flexible, OSUflex) container taking 2.6 megabits per second as particles, flexibly multiplexes by adopting fixed-length frames, provides finer time slot granularity and a more concise bandwidth lossless adjustment mechanism, supports the high-efficiency bearing of 2 megabits/second-100 gigabits/second rate customer service, and enables the OTN to have the capability of sinking from a backbone core to an access terminal and to be closer to a service end user.

With the development of flexible cloud entry/computation business, the dynamic performance of the OTN bearing business is gradually enhanced, and the OTN network needs to have the capability of accurately sensing and flexibly matching business demands so as to provide networking private line and cloud entry private line services for high-quality enterprise private line and exquisite home-width business. The OSU technology can well meet the changeable and large-scale flow demand of the big data age, and the OSU is becoming the mainstream technology of the OTN gradually.

As more and more communication traffic is handled by OTNs, there is an increasing need for OTN management. For example, intermediate devices in an OTN are managed.

Currently, in the process of managing the intermediate device in the OTN, the user device is required to send communication request information to the server that manages the OTN, so that the server instructs the controller to manage the intermediate device in the OTN based on the communication request information, and further ensures that the intermediate device in the OTN can meet the communication requirement of the user device.

That is, in the prior art, an operator can adjust the bandwidth size of the optical channel data unit (optical channel data unit, ODU) connection by using G-Hao (a bandwidth adjustment protocol), but the bandwidth adjustment step of the technology is determined by the ODU bandwidth granule size, and the bandwidth of the ODU connection can only be switched between the fixed bandwidth sizes of ODU0, ODU1, ODU2, etc., so a serious bandwidth idle situation still exists. Although the problem of bandwidth waste can be solved by using OSU connection, the bandwidth size of the OSU connection is still adjusted by manual configuration of operation and maintenance personnel at present.

However, in the above technical solution, the controller can only manage the intermediate device in the OTN when the server senses the communication request information from the user device, which increases the management steps of the intermediate device and reduces the management efficiency of the intermediate device.

In addition, as the number of users increases, the service demand of OTN processing changes greatly, and there is a problem of high operation and maintenance cost.

Therefore, it is necessary to provide a system and a method for automatically establishing services and adjusting bandwidth based on service awareness, which automatically perceive the user traffic demand, automatically establish services and automatically adjust bandwidth, reduce the operation and maintenance cost, and improve the management efficiency of the intermediate device.

In order to solve the above-mentioned problems, an embodiment of the present application provides a method for managing an intermediate device, where the method for managing an intermediate device provided by the embodiment of the present application is applied to a scenario for managing an intermediate device in an OTN. The controller may receive monitoring information from a target intermediate device connected to the user device to be monitored in the OTN, and determine a bandwidth requirement parameter of the user device to be monitored. And then, the controller can generate a bandwidth adjusting instruction for indicating to adjust the intermediate equipment to an operation state meeting the bandwidth demand parameter of the user equipment to be monitored according to the bandwidth demand parameter of the user equipment to be monitored, and send the bandwidth adjusting instruction to the target intermediate equipment. That is, the controller can manage bandwidth resources provided by the intermediate device for the to-be-monitored user device according to bandwidth requirement information fed back by the intermediate device used by the to-be-monitored user device in the OTN, so as to ensure that the intermediate device used by the to-be-monitored user device can meet the bandwidth requirement of the to-be-monitored user device. Thus, the management step of the intermediate device can be simplified, and the management efficiency of the intermediate device can be improved. And the target intermediate device may read the service information sent by the user device to be monitored in response to the monitoring policy for indicating to monitor the service information sent by the user device to be monitored, determine the bandwidth demand parameter of the user device to be monitored, generate monitoring information including the bandwidth demand parameter of the user device to be monitored, and feed back the monitoring information to the controller. That is, the intermediate device may feed back bandwidth resources required by the user device to be monitored to the controller by monitoring real-time bandwidth requirements of the user device to be monitored. Therefore, accurate perception of the communication service can be realized, the time delay for adjusting the bandwidth resource is reduced, and the stability of the communication service is improved.

The following describes an implementation environment of an embodiment of the present application.

As shown in fig. 1, a schematic diagram of a communication system according to an embodiment of the present application may include: a controller 101, a target intermediary device (e.g., intermediary device 102), and a first user device (e.g., user device 103). Wherein the intermediate device 102 may be in wired/wireless communication with the controller 101, the user device 103, respectively.

Wherein the controller 101 may send a listening policy for listening to traffic information between the user equipment 103 and a preset communication object to the intermediate equipment 102, the intermediate equipment 102 having established a communication connection with the preset communication object (i.e. the intermediate equipment 102 stores preset transmission path information with the preset communication object). Thereafter, the intermediate device 102 may read the traffic information to be transmitted including the bandwidth requirement parameter and the information of the object to be communicated from the user device 103 in response to the listening policy from the controller 101, to obtain the bandwidth requirement parameter and the information of the object to be communicated. The intermediary device 102 may then determine whether the object to be communicated is the same as the preset communication object.

If the intermediate device 102 determines that the object to be communicated is the same as the preset object to be communicated, the intermediate device 102 feeds back the bandwidth requirement parameter in the service information to be transmitted to the controller 101, and sends first information for indicating that the preset object to be communicated is not changed to the controller 101. Thereafter, the controller 101 may generate a bandwidth adjustment instruction for instructing to adjust the intermediate device to an operation state satisfying the bandwidth demand parameter according to the bandwidth demand parameter fed back by the intermediate device 102 in response to the first information from the intermediate device 102, and transmit the bandwidth adjustment instruction to the intermediate device 102. Then, the intermediate device 102 may switch to an operation state satisfying the bandwidth demand parameter in response to the bandwidth adjustment instruction from the controller 101, and transmit the service information to be transmitted according to the preset transmission path information.

If the intermediate device 102 determines that the object to be communicated is different from the preset object to be communicated, the intermediate device 102 feeds back the bandwidth requirement parameter and the object to be communicated in the service information to the controller 101, and sends second information for indicating that the preset object to be communicated is changed to the controller 101. Then, the controller 101 may determine, in response to the second information from the intermediate device 102, target transmission path information between the user device 102 and the object to be communicated according to the object to be communicated information fed back by the intermediate device 102, and generate, according to the bandwidth requirement parameter fed back by the intermediate device 102, a bandwidth adjustment instruction for instructing to adjust the intermediate device to an operation state satisfying the bandwidth requirement parameter. Next, the controller 101 may transmit a bandwidth adjustment instruction and target transmission path information to the intermediate device 102. Thereafter, the intermediate device 102 may switch to an operation state satisfying the bandwidth demand parameter in response to the bandwidth adjustment instruction from the controller 101, and store the target transmission path information from the controller 101 while transmitting the traffic information to be transmitted according to the target transmission path information.

Specifically, the controller 101 may generate a monitoring policy for monitoring traffic information between the user equipment 103 and a preset communication object through the traffic management module 104, and send the monitoring policy to the intermediate equipment 102. Thereafter, the intermediate device 102 may read, by the traffic monitoring module 108, traffic information to be transmitted including the bandwidth requirement parameter and the information of the object to be communicated from the user device 103 in response to the listening policy from the controller 101, to obtain the bandwidth requirement parameter and the information of the object to be communicated. The intermediary 102 may then determine, via the traffic monitoring module 108, whether the object to be communicated is the same as the preset communication object.

If the intermediate device 102 determines, through the traffic monitoring module 108, that the object to be communicated is the same as the preset communication object, the intermediate device 102 generates, through the traffic monitoring module 108, first information for indicating that the preset communication object is not changed, and sends, to the controller 101, the bandwidth requirement parameter and the first information in the service information to be transmitted. Thereafter, the controller 101 may generate a bandwidth adjustment instruction for instructing to adjust the intermediate device to an operation state satisfying the bandwidth demand parameter through the bandwidth adjustment sub-module 107 in response to the first information from the intermediate device 102 and the bandwidth demand parameter, and transmit the bandwidth adjustment instruction to the intermediate device 102. Then, the intermediate device 102 may switch to an operation state satisfying the bandwidth demand parameter in response to the bandwidth adjustment instruction from the controller 101, and transmit the service information to be transmitted according to the preset transmission path information.

If the intermediate device 102 determines, through the traffic monitoring module 108, that the object to be communicated is different from the preset communication object, the intermediate device 102 generates, through the traffic monitoring module 108, second information indicating that the preset communication object is changed, and sends, to the controller 101, the bandwidth requirement parameter and the second information in the service information to be transmitted. Thereafter, the controller 101 may determine, through the traffic setup sub-module 106, target transmission path information between the user equipment 102 and the object to be communicated in response to the second information and the bandwidth demand parameter from the intermediate equipment 102, and generate, through the bandwidth adjustment sub-module 107, a bandwidth adjustment instruction for instructing to adjust the intermediate equipment to an operation state satisfying the bandwidth demand parameter. Next, the controller 101 may transmit a bandwidth adjustment instruction and target transmission path information to the intermediate device 102. Thereafter, the intermediate device 102 may switch to an operation state satisfying the bandwidth demand parameter in response to the bandwidth adjustment instruction from the controller 101, and store the target transmission path information from the controller 101 while transmitting the traffic information to be transmitted according to the target transmission path information.

It should be noted that, for the process of the first intermediate device responding to the target listening policy, reference may be made to the description of the target intermediate device responding to the target listening policy, which is not described herein.

It may be appreciated that the controller may determine a target intermediate device connected to the first user device in the OTN, generate a target listening policy, and send the target listening policy to the target intermediate device in response to an operation instruction input by a worker for instructing to monitor a target communication relationship between the first user device and the second user device. That is, the controller may manage the intermediate device used by the user device to be monitored by indicating the intermediate device used by the user device to be monitored to monitor the bandwidth requirement information of the user device to be monitored. In this way, the operability of the management intermediate device can be improved.

In some embodiments, the service information may further include: the identification of the communication object, the target listening policy may include: the identification of the second user equipment, the target service information may further include: the identification of the third user equipment, the target monitoring information may further include: target information. The third user equipment is a communication object of the first user equipment, and the target information is used for indicating whether the communication object of the first user equipment is changed or not.

In the embodiment of the present application, as shown in fig. 4, in the method for managing an intermediate device provided in the embodiment of the present application, S202 may include: S401-S403.

S401, the target intermediate device determines whether the identification of the third user device is the same as the identification of the second user device.

That is, the target listening information may include: and second information.

In an embodiment of the present application, after S204, the method may further include: s404.

S404, the controller determines whether the target information is the first information.

In some embodiments, if the controller determines that the target information is the first information, the controller performs S205.

In other embodiments, if the controller determines that the target information is the second information, the controller determines a target transmission path between the first user equipment and the third user equipment in the OTN, where the target transmission path includes: target intermediate device. Then, the controller may generate a target bandwidth adjustment instruction according to the bandwidth requirement parameter of the first user equipment, and send the target bandwidth adjustment instruction to all intermediate devices in the target transmission path.

It should be noted that, for the process of determining, by the controller, the target transmission path between the first ue and the third ue in the OTN, reference may be made to the prior art that the controller allocates an intermediate device to the ue to establish the transmission path, which is not described herein.

It should be noted that, for the process of any intermediate device in the target transmission path responding to the target bandwidth adjustment command, reference may be made to the description of the target intermediate device responding to the target bandwidth adjustment command, which is not repeated herein.

It can be understood that the target intermediate device may determine the service type initiated by the first user device (e.g. interact with a communication object having an established communication relationship or interact with a communication object not having an established communication relationship) by monitoring the service information sent by the first user device, so as to feed back the service type initiated by the first user device to the controller. And then, the controller can manage the intermediate equipment used by the first user equipment (such as creating a transmission path or adjusting bandwidth resources) according to the service type initiated by the first user equipment, so that the intermediate equipment used by the first user equipment can meet the communication requirement of the first user equipment, and the service information sent by the first user equipment can be normally transmitted. Therefore, the automatic management of the intermediate equipment can be realized, the management efficiency of the intermediate equipment is improved, and the operation and maintenance cost of the intermediate equipment is reduced.

In some embodiments, as shown in fig. 5, after S404, if the controller determines that the target information is the first information, the method may further include: S501-S504.

S501, a controller acquires historical bandwidth parameters between first user equipment and second user equipment.

In one possible implementation, the controller stores historical bandwidth parameters between a plurality of user devices for which communication relationships have been established. The controller may obtain a historical bandwidth parameter between the first user device and the second user device from a historical bandwidth parameter between a plurality of user devices for which a communication relationship has been established based on the identification of the first user device and the identification of the second user device.

S502, the controller determines whether the bandwidth requirement parameter of the first user equipment is larger than the historical bandwidth parameter.

In some embodiments, if the controller determines that the bandwidth requirement parameter of the first user device is greater than the historical bandwidth parameter, the controller performs S205.

In other embodiments, if the controller determines that the bandwidth requirement parameter of the first user device is less than or equal to the historical bandwidth parameter, the controller performs S503.

S503, the controller updates the target times to obtain updated target times.

The target times are times when the bandwidth parameter between the first user equipment and the second user equipment is continuously reduced.

S504, the controller determines whether the updated target times are smaller than a preset times threshold.

In some embodiments, if the controller determines that the updated target number of times is greater than or equal to the preset number of times threshold, the controller performs S205.

In other embodiments, the controller does not manage the target intermediary device if the controller determines that the updated target number of times is less than the preset number of times threshold.

It can be appreciated that the controller determines whether to manage the bandwidth resource provided for the first user equipment in the target intermediate equipment by verifying the bandwidth requirement parameter of the first user equipment. Thus, not only can the stable operation of the communication service between the user equipment be ensured, but also the management efficiency of bandwidth resources in the intermediate equipment can be improved.

In some embodiments, the target listening policy may further comprise: a preset rising threshold and a preset falling threshold. And under the condition that the target intermediate equipment determines that the target information is the first information, the target intermediate equipment can determine whether the bandwidth requirement parameter of the first user equipment is larger than a preset rising threshold.

In one possible implementation manner, if the target intermediate device determines that the bandwidth requirement parameter of the first user device is greater than the preset rising threshold, the target intermediate device updates the first number of times, obtains the updated first number of times, and determines whether the updated first number of times is less than the preset number of times threshold. The first frequency is the frequency that the bandwidth parameter between the first user equipment and the second user equipment is continuously higher than a preset rising threshold.

In one possible design, if the target intermediate device determines that the updated first number of times is greater than or equal to the preset number of times threshold, the target monitoring information generated by the target intermediate device may further include: third information indicating an increase in bandwidth requirements of the first user equipment. And then, the controller can generate a first bandwidth adjusting instruction according to the bandwidth demand parameter of the first user equipment and the third information, and send the first bandwidth adjusting instruction to the target intermediate equipment. The first bandwidth adjusting instruction is used for instructing the target intermediate device to increase bandwidth resources provided for the first user device to meet the bandwidth requirement parameter of the first user device. The target intermediary device may then receive the first bandwidth adjustment instruction from the controller and respond to the first bandwidth adjustment instruction.

In another possible design, if the target intermediate device determines that the updated first time number is less than the preset number of times threshold, the target intermediate device does not generate the target listening information.

In another possible implementation manner, if the target intermediate device determines that the bandwidth requirement parameter of the first user device is less than or equal to the preset rising threshold, the target intermediate device determines whether the bandwidth requirement parameter of the first user device is less than the preset falling threshold, and the preset falling threshold is less than the preset rising threshold.

In one possible design, if the target intermediate device determines that the bandwidth requirement parameter of the first user device is greater than or equal to the preset drop threshold, the target intermediate device does not generate the target monitoring information.

In another possible design, if the target intermediate device determines that the bandwidth requirement parameter of the first user device is less than the preset drop threshold, the target intermediate device updates the second number of times, obtains the updated second number of times, and determines whether the updated second number of times is less than the preset number of times threshold. The second frequency is the frequency that the bandwidth parameter between the first user equipment and the second user equipment is continuously lower than a preset descending threshold.

Optionally, if the target intermediate device determines that the updated second number of times is greater than or equal to the preset number of times threshold, the target monitoring information generated by the target intermediate device may further include: fourth information indicating a reduced bandwidth requirement of the first user equipment. And then, the controller can generate a second bandwidth adjusting instruction according to the bandwidth demand parameter of the first user equipment and the fourth information, and send the second bandwidth adjusting instruction to the target intermediate equipment. The second bandwidth adjusting instruction is used for indicating the target intermediate device to reduce the bandwidth resource provided for the first user device to meet the bandwidth requirement parameter of the first user device. The target intermediary device may then receive a second bandwidth adjustment instruction from the controller and respond to the second bandwidth adjustment instruction.

Optionally, if the target intermediate device determines that the updated second number of times is smaller than the preset number of times threshold, the target intermediate device does not generate the target monitoring information.

In some embodiments, the target listening policy may further comprise: a preset statistical period and a preset sampling interval. And the target intermediate equipment can read the target service information from the first user equipment according to the preset sampling interval in the preset statistical period.

It should be noted that, the preset sampling interval determines the accuracy of flow monitoring, and sets a smaller sampling interval for the traffic with strong burstiness, and sets a larger sampling interval for the traffic with steady rate change.

The following describes, with reference to a specific example, a procedure in which a target intermediate device responds to a target listening policy.

Exemplary, as shown in fig. 6, the size relationship between the flow (i.e. bandwidth requirement parameter) of the first user equipment read by the target intermediate device at each sampling interval in the preset statistical period and the preset rising threshold and the preset falling threshold is shown. In the preset statistical period, if the target intermediate device determines that the flow of the first user device exceeds the rising threshold for a period of time (i.e., the first time number) and the period of time is longer than the effective time (i.e., the preset frequency threshold), the target intermediate device may report a flow increase notification (i.e., the third information). If the target intermediate device determines that the traffic of the first user device is lower than the drop threshold and the duration (i.e., the second number of times) exceeds the valid time, the target intermediate device may report a traffic reduction notification (i.e., the fourth information).

Optionally, when the target intermediate device monitors that the new traffic arrives (i.e. the identifier of the third user device is different from the identifier of the second user device) according to the traffic monitoring policy (i.e. the target monitoring policy), the target intermediate device immediately reports the notification of the new service requirement (i.e. the second information).

S902, the controller system issues a traffic monitoring policy to a corresponding user network interface (user network interface, UNI) on the optical transport network device (e.g., the target intermediate device).

S903, the optical transport network device returns confirmation information.

S904, the optical transport network equipment starts to monitor the service according to the flow monitoring strategy.

In some embodiments, when the traffic monitoring module in the optical transport network device detects that the new traffic first occurs an event (i.e., the second information) or the traffic demand change event (i.e., the first information), the optical transport network device performs S905.

S905, the optical transport network device reports the event to the controller system by means of notification.

The notification information includes information such as a traffic change notification sequence number, a traffic monitoring policy name, a specific event (i.e., target information), a service bandwidth (i.e., bandwidth requirement parameter), and the like, where the event includes an event of first occurrence of a new traffic and an event of a traffic requirement change.

In some embodiments, the controller system may perform S906 after receiving a new notification (i.e., target snoop information).

S906, the controller system processes the first occurrence event or the flow change event of the new flow in the service management module.

In some embodiments, for the first occurrence of an event in the new traffic, the service automatic establishment module (i.e., the service establishment sub-module) in the controller system maps the new service (i.e., the identifier of the third user device) monitored by the client side to the corresponding device according to the client-UNI mapping database (i.e., the mapping relationship between each intermediate device in the OTN and the connected user device), calculates the service path (i.e., the target transmission path) according to the traffic information such as the service type, the service request bandwidth information, and the source destination address information, and creates the connection information. After that, the controller system may perform S907.

S907, the controller system issues connection information to the device through which the service path passes.

Wherein the device through which the traffic path passes comprises an optical transport network device.

In other embodiments, for traffic change events, a bandwidth auto-adjustment module (i.e., a bandwidth adjustment sub-module) in the controller system recalculates the bandwidth required for the traffic and makes real-time bandwidth adjustments, generating traffic bandwidth adjustment information (i.e., target bandwidth adjustment instructions). The controller system may then execute S908.

S909, the optical transport network equipment completes the whole bandwidth adjustment process through protocol intercommunication among the equipment.

S910, the optical transport network equipment completes the operation of service creation or bandwidth adjustment and then reports the operation to the controller system.

Exemplary, as shown in fig. 10, a seven-node OTN network topology is shown. The OTN comprises: intermediate device a, intermediate device B, intermediate device C, intermediate device D, intermediate device E, intermediate device F, and intermediate device G. The intermediate device a is connected with the user device 1 and the user device 2 respectively, the intermediate device F is connected with the user device 3, and the intermediate device G is connected with the user device 4. Meanwhile, the controller maintains a client-UNI mapping database as shown in table 1. The client-UNI mapping database is generated by collecting and analyzing broadcast traffic of individual UNI ports or is directly populated into the controller system through the upper management system or user.

Table 1 client-UNI mapping database

Client side information	UNI port information
		User equipment 1: MAC1, IP1	A-101
User equipment 2: MAC2, IP2	A-102
		User equipment 3: MAC3, IP3	F-101
User equipment 4: MAC4, IP4	G-101

Assuming that a service is provided from the user equipment 1 to the user equipment 3, the specific steps of automatic creation of the service and automatic adjustment of the bandwidth are as follows:

step one, a worker configures a flow monitoring strategy on a controller system, wherein the flow monitoring strategy monitors service flow with a source MAC address of MAC1 and a destination MAC address of MAC3, the flow monitoring strategy also comprises flow statistics parameters and monitoring UNI names, and the flow statistics parameters comprise a statistics period, a sampling interval, an effective time, a descending threshold and an ascending threshold. The controller system issues the configured traffic monitoring policy to the 101 port on the intermediate device a device.

And step two, after receiving the flow monitoring strategy, the intermediate equipment A equipment returns confirmation information and starts to monitor the service at the 101 port according to the flow monitoring strategy.

Step three, the user equipment 1 starts to send service flow to the destination address, and after the flow monitoring module of the intermediate equipment A monitors that the service flow with the source MAC address of MAC1 and the destination MAC address of MAC3 appears on the 101 port, the notification of the first occurrence event of the new flow is reported to the controller system.

The notification information comprises information such as a flow change notification sequence number, a flow monitoring strategy name, a specific event, a service bandwidth, a source destination address and the like.

And step four, after receiving the new notice, the controller system extracts information in the notice from the service management module to process the first occurrence event of the new flow.

And fifthly, for the first occurrence of an event of the new flow, the service automatic establishment module finds the intermediate device and the UNI port corresponding to the source and destination addresses in the client-UNI mapping database according to the source and destination addresses in the notification information, namely the 101 port of the intermediate device a and the 101 port of the intermediate device F. And then mapping the new service monitored by the client side to the corresponding intermediate device according to the source port and the device information, calculating the service path from the intermediate device A to the intermediate device F according to the service flow information such as the service type and the service request bandwidth information, and automatically issuing the corresponding cross configuration to the intermediate device A, the intermediate device C, the intermediate device E and the intermediate device F through which the service path passes.

Step six, each intermediate device in the intermediate device A, the intermediate device C, the intermediate device E and the intermediate device F completes the operation of creating the service and reports the service to the controller system.

And step seven, when the traffic fluctuates, the flow monitoring module of the intermediate equipment A monitors that the flow demand of which the source MAC address is MAC1 and the destination MAC address is MAC3 appears at the 101 port, the intermediate equipment A analyzes the flow demand change according to the flow statistical parameter, and the analyzed bandwidth adjustment demand is reported to the controller system through a notification.

The notification information comprises information such as a flow change notification sequence number, a flow monitoring strategy name, a specific event, a service target bandwidth and the like;

and step eight, a bandwidth automatic adjustment module in the controller system calculates the bandwidth required by the service according to the OSU granularity, carries out real-time bandwidth adjustment, and transmits service bandwidth adjustment information to a service head node (namely intermediate equipment A), and the intermediate equipment A, the intermediate equipment C, the intermediate equipment E and the intermediate equipment F complete the whole bandwidth adjustment process through protocol intercommunication among the equipment, thereby meeting the requirements of new services such as special lines, videos and the like on flexible bandwidth bearing.

Step nine, reporting and notifying the controller system after each intermediate device in the intermediate device A, the intermediate device C, the intermediate device E and the intermediate device F completes the automatic bandwidth adjustment operation, and storing related information by the controller system.

That is, in the method for managing the intermediate device provided by the embodiment of the application, several modules between the controller and the intermediate device are mutually matched to monitor the service flow in real time, grasp the flow condition in real time, complete the automatic creation of the service and the automatic adjustment of the service bandwidth according to the actual demands of the user, further support the users such as enterprises to jump into the cloud through the OTN network, thereby realizing the capability of accurately sensing the service and flexibly matching the service demands, ensuring the service bandwidth and the stability of the service, reducing the service delay and the like. And the operation and maintenance cost is reduced through automatic creation and bandwidth automatic adjustment of an automatic transmission path based on the flow demand.
