Embodiments of the invention

Embodiments of the present invention will be described in detail below with reference to the drawings in conjunction with the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

It should be noted that the terms "first", "second" and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or order.

In this embodiment, a method for adjusting a service bandwidth is provided. FIG. 1 is a flowchart of a method for adjusting a service bandwidth according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps:

Step S102, determining, according to the client layer service selected by the user, a service layer tunnel carrying the selected client layer service;

Step S104, adjusting the service bandwidth of the determined service layer tunnel.

Through the above steps, bandwidth adjustment can be performed based on multiple client layer services selected by the user, The bandwidth of the tunnel and the client layer is adjusted to the correct value, which solves the problem that the bandwidth adjustment of the client layer service bandwidth provided in the related technology is easy to cause waste of resources and low accuracy, and realizes batch adjustment of service bandwidth parameters.

In the implementation process, the end-to-end network management software batch service bandwidth adjustment is taken as an example to implement a method for batch adjusting service bandwidth parameters to meet user requirements and comply with CAC rules. The service adjustment is based on the tunnel as the atomic level adjustment unit, that is, all the client layer services carried by one tunnel, and the processing is completed at one time. The user can select one or more client layer services and send the CAC parameters to the target value and then send them to the server. The server searches all related service layer tunnels A according to the customer layer service selected by the user, and then searches the client layer service according to the tunnel to find the service layer tunnel set B of the client layer service. If the number of tunnels included in the service layer tunnel set B is greater than the number of tunnels included in the service layer tunnel set A, then further roundup of services and tunnels is required until new services and tunnels are not found. After all the tunnels and services are found, the bandwidth value of each tunnel and service is calculated. The tunnel bandwidth value is adjusted to the sum of the current client layer bandwidths, and the pseudowire data with the smaller bandwidth is delivered, and then the tunnel is delivered. The final bandwidth value, and finally the pseudowire data with the bandwidth increasing. The following description will be made in conjunction with the following embodiments.

In step S102, determining, according to the selected client layer service, the service layer tunnel carrying the selected client layer service may include the following steps:

Step 1: Searching for a service layer tunnel set according to the selected client layer service, where each service layer tunnel in the service layer tunnel set includes services of part or all of the selected client layer services;

Step 2: Perform a filtering operation on the client layer service carried on each service layer tunnel in the service layer tunnel set, and obtain the remaining service layer tunnels, where the remaining service layer tunnels only carry the selected part of the client layer service or All business;

Step 3: Analyze the remaining service layer tunnels to determine whether a new client layer service or a new service layer tunnel appears; if yes, return to step 1; if not, the remaining service layer tunnels are determined as the determined service layer. tunnel.

In an embodiment, the user can select a client layer service that needs to perform bandwidth adjustment, for example, an E-line service and a TDM service, thereby entering a service bandwidth adjustment interface. According to the customer layer service selected by the user, analyze and find all service layer tunnels related to the customer layer service selected by the user and search All customer layer services carried by these service layer tunnels are extracted.

In the implementation process, firstly, the E-TREE/E-LAN/L3VPN service existing in the customer layer service can be filtered out, and the client layer service shared with the E-TREE/E-LAN/L3VPN service tunnel is filtered out. Secondly, after the above filtering operation is completed, only the E-line service and the TDM service are left in the client layer service information, and all service layer tunnels related to these services can only carry the E-line service and the TDM service. Then, various types of services that have been filtered out are presented to the user on a specific browsing page. Finally, for the customer layer services remaining after the above filtering operation, all the service layer tunnels related to these client layer services can be further analyzed to observe whether there is a new service layer tunnel; if there is a new service layer In the tunnel, the new service layer tunnel needs to be analyzed according to the above steps. That is, whether the newly-created service layer tunnel can only carry E-LINE service and TDM service or bear other types of client layer services at the same time. Until there is no new service layer tunnel appearing for this.

Under normal circumstances, new service layer tunnels will not appear again. However, from the perspective of the accuracy and completeness of the technical solution, an analysis solution is proposed for the occurrence of the above special cases to prevent the occurrence of special configurations. .

Before the service bandwidth of the determined service layer tunnel is adjusted, the following operations may be included in the step S104:

Step 4: Determine, according to the preset type in the service list, whether the service has configured the corresponding bandwidth parameter and/or whether the user selects the bandwidth adjustment to determine the state of the CAC switch and the flow control switch.

In an embodiment, the service list may be related to the information before the adjustment of the service pseudowire in the initial situation, which may include, but is not limited to, a CAC switch, a flow control switch, and bandwidth parameter information (eg, CIR, CBS, PIR). , PBS, color blindness, color sensitivity). Each column of information in the business list is required to support multiple types of sorting (for example: ascending order, descending order, sorting by modified date, sorting by parameter type) for the user to view. At the same time, the business list also needs to support Shift, CTRL, mouse mode for multiple selection, to select business operations. The user can right-click to enter the modification interface, and click OK after completing the bandwidth modification operation. The final service list can display the value that the business pseudowire needs to be modified.

In step 4, according to whether the preset type service has configured the corresponding bandwidth parameter and/or whether the bandwidth adjustment is selected to determine the state of the CAC switch and the flow control switch, the following may be included. One:

(1) If the preset type service has been configured with the corresponding bandwidth parameter, the CAC switch and the flow control switch are in an open state;

(2) If the preset type service is not configured with the corresponding bandwidth parameter and is not selected by the user for bandwidth adjustment, the CAC switch and the flow control switch are in the off state;

(3) If the preset type service is selected by the user and the user completes bandwidth adjustment for the preset type service, the CAC switch and the flow control switch are turned on.

In an embodiment, it is assumed that the above client layer service is an Ethernet service:

(a) For Ethernet services that have bandwidth parameters configured, the adjusted CAC switch and flow control switch will be forced to ON. That is, regardless of whether the user has performed an adjustment operation, the tool automatically performs a switch forced on.

(b) For Ethernet services that do not have bandwidth parameters configured (CAC off, flow control off, and no bandwidth parameters), if the user does not perform the adjustment operation, it remains unchanged.

(c) If the user selects part of the Ethernet service (whether or not the bandwidth parameter is configured), the bandwidth adjustment operation is required. At this time, the bandwidth adjustment interface is popped up, and the bandwidth parameter (CIR, CBS, PIR, PBS, color blindness, color sensitivity) is performed by the user. ) Information input, and if the user sets the bandwidth parameter, the CAC switch and flow control switch of the service will be forcibly set to ON.

In another embodiment of the present invention, it is assumed that the above client layer service is a time division multiplexing (TDM) service:

(a) The “Overlay TDM Service Bandwidth” option switch can be added to the operation interface provided to the user. If the user selects the overlay option switch, the CIR bandwidth parameter will be automatically set according to 3M in the TDM service list at the same time. The CAC switch and flow control switch will be forced to be turned on.

For the TDM service, it can also perform bandwidth modification operations, and the operation rules are basically the same as those of the Ethernet service.

(b) If the user does not select the overlay option switch, the CAC switch and flow control switch of the service will be forced to be off and the bandwidth parameter is empty.

In step S104, adjusting the service bandwidth of the determined service layer tunnel may include Next steps:

Step 5: superimposing service bandwidth of the client layer carried on the determined service layer tunnel;

Step 6. Set the determined CAC switch and the flow control switch of the service layer tunnel to an on state and set the determined adjustment mode of the service layer tunnel to an adaptive adjustment.

In an embodiment, the tunnel information is not presented in the display interface, but only the server searches for the relevant tunnel and performs calculation and delivery. Moreover, whether the tunnel will converge can be selected at the initial setting, and it can choose to maintain the original value, or choose to converge the tunnel, or choose to not converge the tunnel. For the client layer service that has changed, the bandwidth of the tunnel will be automatically superimposed (that is, the bandwidth of all client layers is superimposed). The CAC switch and flow control switch of the tunnel will be forcibly set to on, and the tunnel bandwidth will be set automatically. , turn on the color sensitive mode. In the implementation process, the above CBS, PIR, PBS, color blindness, and color sensitivity are kept as constant as possible. If the original value given by the above parameters is not within a predetermined reasonable value range (ie, an illegal value), then The default value assigned by the above parameters is replaced by a preset default value.

After the service bandwidth of the determined service layer tunnel is adjusted, the following steps may be further included in the step S104:

Step 7. Perform CAC pre-verification on the selected client layer service carried on the determined service layer tunnel.

Step 8: Adjust the service bandwidth of the determined service layer tunnel to the total bandwidth of the client layer service that is currently pre-verified by the CAC;

In step 9, the service pseudowire with the service bandwidth becomes smaller, the sum of the bandwidth, and the service pseudowire with the service bandwidth become larger.

In an embodiment, before the application is sent, the CAC pre-verification may be performed in advance. If the client layer service that cannot be passed by the CAC check is found, it will not be delivered to the user equipment, and the service list is recorded to prompt user. Secondly, the pre-verified tunnel is adjusted to the sum of the current client layer bandwidth: all tunnel CAC switches are turned on, and the fixed bandwidth tunnel is changed into a tunnel with automatically adjustable bandwidth. Then, the pseudo-line with the reduced service bandwidth is delivered to the user equipment: only the client layer service of the tunnel with the pre-verification succeeded is delivered. Then, the relevant tunnel bandwidth without failure is adjusted to the sum of the bandwidths input by the user. After that, adjust the remaining pseudowire bandwidth: only pre-verify in (ii) The client layer service carried on the tunnel. Finally, analyze all the verification anomalies and the delivery device abnormalities, set the relevant tunnel and client layer services to adjust the bandwidth failure, set the remaining tunnel and client layer services to adjust the bandwidth successfully, and return to the client to present to user.

In the case that the above-mentioned part of the tunnel or the client layer service is abnormal (for example, fails to pass the CAC check), it does not affect the normal tunnel and the client layer service is delivered to the user equipment. Or the client layer service is excluded from the subsequent bandwidth calculation and is delivered to the user equipment. In other words, the technical solution provided by the embodiment of the present invention can support abnormality of part of the tunnel or client layer service and the rest of the tunnel or client layer service is normal. A scenario in which the normal tunnel or client layer service participates in the calculation and is delivered to the user equipment.

For the above-mentioned embodiments provided by the present invention, the abnormal service rectification and the bandwidth modification of the entire network of the network existing network are satisfied, and the bandwidth transformation needs of the existing network service are met, including the service bandwidth from scratch, from the existing to the bandwidth adjustment requirement, Through the gradual rectification of the existing network services, the existing network gradually transitions from the incremental CAC mode to the full CAC mode. After the batch service parameter adjustment tool is available, it can be transitioned to the full CAC mode through the step-by-step transformation method. The one-step full-size CAC method can be subsequently faded, thereby avoiding the inconsistency on the current network caused by the one-step full-size CAC method. Data problems and processing.
