Description
Technical Field
The invention belongs to the technical field of network equipment management systems, and particularly relates to a method and a device for controlling plane link display.
Background
The conventional OTN (Optical Transport Network) provides a single protection method and cannot be dynamically changed. When a user creates a PC (personal Connection), if the user does not know information such as an operation state and a remaining bandwidth of the entire network, the user often needs to try many times, and the user cannot accurately create a circuit. An ASON (automatic Switched Optical Network) performs automatic discovery of a link by adding a control plane, and adds information such as bandwidth and the like on the link, thereby providing a plurality of protection modes and circuit failure recovery modes to meet different service scene requirements of users.
The links discovered by the control plane at present mainly include data links and TE (Traffic Engineering) links. The traditional network management system separately displays the data link and the TE link, and a user needs to operate the two links before creating the SPC circuit, and then needs to switch back and forth between two interfaces, which increases the complexity of user operation and is inconvenient for unified operation and management. Especially when the forward source port and the reverse sink port of the optical layer TE link are different, association of the forward TE link and the reverse TE link is not facilitated. The bandwidth information of the link is not clear, the total bandwidth and the available bandwidth, the total resource utilization condition and the user cannot visually acquire the bandwidth information, when the SPC circuit is created on the link, whether the link can be used or not cannot be accurately judged, and the information of the TE link in the opposite direction cannot be accurately displayed. In addition, bandwidth information of the link is ambiguous, and a user cannot intuitively acquire resource information such as total resources, available resources, and resource utilization rate of the link, so that when creating the SPC circuit on the link, whether the link can create the circuit or not and the number of created circuits cannot be accurately determined, and the possibility of creating failure by the user is increased.
Therefore, there is a need for a link display method, which can display the association between the data link and the TE link, and can associate the TE link with the optical layer even if the forward source and the reverse sink are not in the same port; and the state of the link and the resource utilization condition can be visually displayed, so that the user can conveniently create the SPC circuit, the invalid operation of the user is reduced, and the efficiency of creating the SPC circuit is improved.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the respective embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Example 1
In order to solve the technical problems that the conventional link separate display is not convenient for unified operation and management and an SPC circuit cannot be accurately created due to resource information deficiency, an embodiment of the present invention provides a method for controlling a planar link display, as shown in fig. 1, which mainly includes:
A plurality of nodes are usually included in the whole ASON network topology, and each two adjacent nodes have a corresponding data link and TE link therebetween. Taking the simple ASON network topology shown in fig. 2 as an example, there are 5 nodes in total, the links between the nodes shown in the figure are TE links, and the data links between the nodes are not shown. The data link and the TE link both have corresponding link information, and the link information comprises source and destination nodes, ports, other link attributes and other related information corresponding to the links.
And step 20, between every two adjacent nodes, performing association between the TE link and the data link according to whether the source host ports are the same, performing forward and reverse association of the TE link according to whether the forward and reverse source host ports are the same or whether the TE link is in the same WSS group, and determining the state of the TE link according to the association result.
This step is mainly to complete two types of association of TE links: one is the association of the TE link with the data link, and the other is the forward-reverse association of the TE link. With reference to fig. 3, the specific process is as follows:
With reference to fig. 2, in the embodiment of the present invention, taking the current selection of node 1 and node 2 for research as an example, node 1 may be used as a source node, node 2 may be used as a sink node, and the source and sink ports of the data link and the TE link between the two nodes are respectively analyzed according to the previously obtained link information; the source port is the port of the link on the node 1, and the sink port is the port of the link on the node 2.
The step is mainly to perform association between the TE link and the data link, i.e. the first type of association. Continuing with fig. 2, when node 1 and node 2 are selected for research, if the source ports of the TE link and the data link are the same port (i.e., the ports of the two links on node 1 are the same) and the sink port is the same port (i.e., the ports of the two links on node 2 are the same), the TE link and the data link corresponding to the TE link may be associated, and at this time, the association is successful.
The step is mainly to perform forward and reverse association of the TE link, i.e. the second type of association. The TE links are specifically divided into two categories, i.e., electrical layer TE links and optical layer TE links, where:
1) for electrical layer TE links, the source port of the forward link is the sink port of the reverse link, i.e., the forward source port and the reverse sink port are the same port, and therefore, the association can be directly performed according to whether the forward source port and the reverse sink port are the same. When a forward source port and a reverse sink port on the node i are the same and a forward source port and a reverse sink port on the node j are the same, performing forward and reverse association on the electrical layer TE link between any two adjacent nodes i and j, wherein the association is successful at this moment.
As shown in fig. 3, between node 1 and node 2, the forward source port and the reverse sink port on node 1 are the same port (i.e. when the direction from node 1 to node 2 is positive, the forward source port and the reverse sink port are on the same single disk of node 1), and the forward source port and the reverse sink port on node 2 are also the same port (i.e. when the direction from node 2 to node 1 is positive, the forward source port and the reverse sink port are on the same single disk of node 2), so that the forward TE link and the reverse TE link are directly associated according to that the source port of the forward link is the sink port of the reverse link.
2) For the optical layer TE link, a WSS (Wavelength Selective Switch) group is introduced for association: selecting a related WSSD (Wavelength Selective Switch Demultiplexer) disc and a related WSSM (Wavelength Selective Switch Multiplexer) disc on each node in advance to configure a WSS group, namely dividing a related single disc into one WSS group and storing the preconfigured WSS group into a database of a network manager; and then, the single disks of the forward source port and the reverse sink port can be associated with each other in the same WSS group according to the pre-configured WSS group. Between any two adjacent nodes i and j, when the single disks of the forward source port and the reverse sink port on the node i are in the same WSS group, and the single disks of the forward source port and the reverse sink port on the node j are in the same WSS group, performing forward and reverse association on the optical layer TE link, where the association is successful at this time.
As shown in fig. 4, between node 1 and node 2, the single disks of the forward source port and the reverse sink port on node 1 are in the same WSS group (that is, when the direction from node 1 to node 2 is positive, the single disk of the forward source port and the single disk of the reverse sink port are in the same WSS group of node 1), and the single disks of the forward source port and the reverse sink port on node 2 are also in the same WSS group (that is, when the direction from node 2 to node 1 is positive, the single disk of the forward source port and the single disk of the reverse sink port are in the same WSS group of node 2), so that the forward and reverse light layer TE links can be directly associated.
The link analysis and link association between two adjacent nodes i and j can be completed through the steps 201 to 203, then all nodes are traversed by adopting the same method, two adjacent nodes are selected each time to perform the link analysis and link association, the links between all nodes in the whole network are analyzed step by step, and finally the link association between all nodes is completed.
When the association between the TE link and the data link is performed in step 202, if the association fails, the state of the TE link is determined as "data link missing"; if there is an alarm on the data link that causes the TE link to be broken and the SPC circuit cannot be normally created, the state of the TE link is determined to be "broken". When the forward and reverse association of the TE link is performed in step 203, if the association fails, the state of the TE link is determined to be "reverse link missing". If the association of the TE link with the data link is successful in step 202 and the forward-reverse association of the TE link is successful in step 203, the state of the TE link is determined to be "normal".
And step 30, acquiring resources on each TE link port of the whole network, counting the total number of the resources and the available number of the resources, and calculating the resource utilization rate of the TE link according to the total number of the resources and the available number of the resources.
In the embodiment of the invention, a network manager can acquire resources on each TE link port of the whole network from a control plane to carry out resource statistics; wherein, the resource state is "control plane available" indicates that the resource is available, and the resource state is "control plane occupied" indicates that the resource is not available (because it is already occupied).
For the optical layer TE link, if the resource type is wavelength, the total number of wavelengths supported on the port is taken as the total number of resources, the number of wavelengths in the "control plane available" state is taken as the available number of resources, and then the resource utilization rate is calculated according to the total number of resources and the available number of resources.
For the electrical layer TE link, the resource type is an ODUk (Optical channel Data Unit), and the number of ODUs 0 can be converted into a unified number, the total number of ODUs 0 on the port is taken as the total number of resources, the number of ODUs 0 in the state of "control plane available" is taken as the available number of resources, and the resource utilization rate is calculated according to the total number of resources and the available number of resources.
The calculation formula of the resource utilization rate is as follows:
and step 40, displaying the TE link on the control plane according to the state of the TE link and the resource utilization rate, so that a user can select the TE link to create the SPC circuit according to the display information of the control plane.
In a particular embodiment, the color and line type of the TE link may be displayed on the control plane according to the state of the TE link and resource utilization. For example, if the state of the TE link is "normal", it is displayed as a green solid line; if the state of the TE link is "down," it is shown as a solid red line; if the state of the TE link is "data link missing", it is displayed as a solid gray line; if the state of the TE link is "reverse link missing", it is shown as a gray dashed line; if the resource utilization of the TE link exceeds a preset threshold (e.g., 80%), a solid yellow line is displayed to prompt the user that the SPC circuit created on the link is too much and heavily loaded, and it is not appropriate to continue creating the SPC circuit, and an attempt may be made to select another TE link with low resource utilization and lesser load to create the SPC circuit. Of course, the specific colors and line types are merely illustrative and are not intended to limit the present invention.
In the embodiment of the present invention, after the data link and the TE link are associated, the attribute of the data link may be associated to the TE link for display, so that the operation on the data link and the TE link, for example, setting basic attributes such as link cost, distance, optical fiber length, and the like, may be completed only on the TE link management interface.
Further, when a user performs SPC circuit creation on the TE link, it is necessary to select a resource whose state is "control plane available" to create the SPC circuit; when the SPC circuit is created, the control plane modifies the state of the corresponding resource to "control plane occupied," indicating that the resource can no longer be used to create the SPC circuit.
By the method for displaying the control plane link, the data link and the TE link are displayed in a correlated manner, namely unified to a network management interface, so that the operation and management of a user are facilitated; meanwhile, by adding a WSS group, the problem that forward and reverse correlation cannot be carried out due to the fact that a forward source port and a reverse sink port in an optical layer TE link are different is solved. In addition, resource related information such as the total number of resources, the available number of resources, the resource utilization rate and the like is newly added on the TE link, and link display is carried out on a control plane according to the state of the TE link and the resource utilization rate, so that a user can conveniently judge whether the TE link can be used for creating the SPC circuit and how many SPC circuits can be created, invalid operation in the process of creating the SPC circuit by the user is reduced, the efficiency of creating the SPC circuit is improved, and the usability of a network management interface is improved.

The link acquisition module is used for acquiring data links and TE links among all nodes of the whole network and acquiring link information of each data link and each TE link; the link information includes source and destination nodes, ports and other link attributes and other related information corresponding to the links.
The link association module is used for associating the TE link with the data link according to whether the source host port is the same or not, performing forward and reverse association of the TE link according to whether the forward and reverse source host ports are the same or whether the forward and reverse source host ports are in the same WSS group or not, and determining the state of the TE link according to the association result.
The resource analysis module is used for acquiring resources on each TE link port of the whole network, counting the total number of the resources and the available number of the resources, and calculating the resource utilization rate of the TE link according to the total number of the resources and the available number of the resources.
The link display module is used for displaying the TE link on the control plane according to the state and the resource utilization rate of the TE link, and specifically, the color and the line type of the TE link can be displayed on the control plane according to the state and the resource utilization rate of the TE link, so that a user can select the TE link to create the SPC circuit according to the display information of the control plane. For example, if the state of the TE link is "normal", it is displayed as a green solid line; if the state of the TE link is "down," it is shown as a solid red line; if the state of the TE link is "data link missing", it is displayed as a solid gray line; if the state of the TE link is "reverse link missing", it is shown as a gray dashed line; if the resource utilization of the TE link exceeds a preset threshold (e.g., 80%), it is shown as a solid yellow line.
Further, the link association module comprises a port resolution module, a first link association module and a second link association module. Wherein:

For the optical layer TE link, if the resource type is wavelength, the optical layer resource analysis module takes the total number of wavelengths supported on the port as the total number of resources, takes the number of wavelengths in the "control plane available" state as the available number of resources, and then calculates the resource utilization rate.
