Example two:
the present embodiment is described in conjunction with specific application examples to supplement the description of the present invention.
In the prior art, the adjustment involved in automatic configuration is limited to the network element formation of the ring system and the migration of the parent-child relationship of the ring system (i.e. the child ring system migrates from one parent ring system to another parent ring system), but does not provide support for the addition and the separation of the ring system; the embodiment provides a specific scheme for the addition of the ring system and the splitting of the ring system while solving the problem that the active management cannot be realized in the existing automatic configuration mode.
As shown in fig. 4, the ring network management method provided in this embodiment includes:
s401: and detecting a new loop system.
S402: and (5) detecting a split ring system.
These two steps are independent steps, but because there is a dependency relationship between the analysis execution result of step S401 in step S402, that is, whether the analysis result of step S401 is performed or not, the analysis result of step S402 may be different, and therefore, the present embodiment divides the analysis into two independent detection steps to be performed step by step.
The "newly added ring" detected by the newly added ring system according to this embodiment does not mean "adding 1 ring system", but automatically finds a specific scene in the existing ring system, where the specific scene is a general name of a scene that does not belong to any ring system network element and is added to an existing ring system or a newly created ring system. And the split ring is split into 2 or more ring systems by 1 ring.
In this embodiment, through a static technical scheme of ring system state detection, it can be realized that operation and maintenance personnel have not entered, wrongly entered, and manually and automatically entered ring system asset information is not accurate enough, and a recommendation of a recommended ring system change calculated based on an actual networking situation of a communication network is provided. The proposal that the embodiment can automatically recognize the ring system change includes: the network element joins the existing ring system, the father ring system is the father ring system joining the ring system, and the father ring system can not be appointed; the network element joins the newly created ring system, the name of the ring system is designated by the user, and the parent ring system is automatically given or designated by the user. The embodiment is a static detection method, which is triggered by a user, and aims to automatically give a change suggestion of ring system resources according to a rule formulated by ring network resource planning and networking current situation, reduce actions of operation and maintenance personnel for maintaining ring network resources, and realize automatic operation and maintenance.
The specific implementation flow of step S401 is shown in fig. 5, and includes the following steps:
s501: and acquiring a network element set allLevel _ NEs.
Classifying according to the equipment levels of the network elements to obtain all network elements of all the equipment levels, which support the network elements added into the ring system and all network element sets (all Level _ NEs) (including 1Level _ NEs, … … iLevel _ NEs and … … niLevel _ NEs) which are not affiliated to any ring system; a network element that is not affiliated with any ring system indicates that the network element has not been added to any ring system.
S502: and selecting a network element set iLevel _ NEs to be analyzed.
And taking a network element set which belongs to any ring system and has any equipment hierarchy out of the all level _ NEs set, and taking the network element set as a network element set to be analyzed, and marking as iLevel _ NEs.
S503: and taking the network element NEa in the set iLevel _ NEs as a starting point, and acquiring the maximum network element connected set GatheredNE.
And traversing a maximum network element connected set GatherEDNE-i which has the same equipment level and is not affiliated to any ring system by taking a certain network element NEa in the network element set iLevel _ NEs as a starting point according to a topological link of the network element NEa, wherein i represents the number of the maximally connected network element set obtained by traversing.
Preferably, a deep traversal algorithm is adopted, the network elements meeting the conditions in the traversal process are pushed and added into the gathered ne-i network element set, wherein the network elements meeting the conditions, namely the network elements have the same hierarchy and do not belong to any ring system, and the currently traversed network elements which do not meet the conditions are not pushed. Specifically, the user cannot continue to move forward along the current link, and needs to examine the top-of-stack network element and continue to traverse along other links, and if the top-of-stack network element has no other links for continuous traversal, the top-of-stack network element is popped up, and the secondary top-of-stack network element is examined continuously and continues to traverse along the links which are not traversed.
During the traversal, the case of "non-compliant network element" includes the following two cases:
5-3.1: the hierarchy of the network element NEk and NEa that is currently traversed is not the same. If NEk has a higher level than NEa and NEk belongs to the ring system RSx, RSx is added to the ring system set RSGm (i.e. the first ring system set referred to above, RSGm is initially empty), and if NEk belongs to multiple ring systems, RSGm is added with a relatively higher level of ring systems.
5-3.2: the network element NEk that is currently traversed to is the same level as NEa and NEk belongs to the ring system RSy. RSy is added to the ring system set RSGn at this time (i.e., the second ring system set referred to above, RSGn is empty in the initial case), and if NEk belongs to a plurality of ring systems, then a ring system level among them is added to RSGn relatively higher.
S504: and determining the ring system RSz corresponding to the maximum network element connected set GatheredNE.
When the flag indicates that stack data is empty, the maximum connection body traversal action is completed, all network element sets (i.e., gathered ne-i) entering the stack will be members of a certain ring system RSz, and the determination principle of RSz is determined according to the number of ring systems in RSGn in the traversal process, which is specifically as follows:
5-4.1: when the number of ring systems in the RSGn is 0, "adjustment suggestion" is "add ring system", the ring system name is specified by the user, and GatheredNE-i is taken as a member of the ring system. At this time, the 'affiliated parent ring system' of the ring system is selected by the user through controls such as a ComboBox, all ring systems contained in the RSGm are listed in the list item (the first ring system is selected by default), and a 'selection ring system …' option is provided for the user to select ring systems not in the RSGm. Preferably, if no ring system is included in the RSGm, the ComboBox has only one and default option "select ring system …" at this time.
5-4.2: when the number of the ring systems in the RSGn is not 0, "adjustment suggestion" is "network element joins the existing ring system", "join ring system" is provided for the user to select through ComboBox, all ring systems included in the RSGn are selected in the list item (the first ring system is selected by default), and in addition, a "selection ring system …" option is provided for the user to select ring systems not in the RSGn. At this time, the "parent ring system to which the joining ring system belongs" is automatically presented according to the "joining ring system" selected by the user, and the user cannot select it. And finally, adding the network elements in the GatheredNE-i into the 'ring system' selected by the user.
The "network element included" field contents of the ring system RSz present the network elements in the largest set of connections gathered ne-i.
S505: an exhaustive list of all network elements within the set iLevel _ NEs.
And (4) removing the network elements in the GatheredNE-i from iLevel _ NEs, and emptying the RSGn and the RSGm. If there are network elements in the iLevel _ NEs, taking out a certain network element from the iLevel _ NEs as the starting point of traversal, and continuing to repeat the processes of the step S503 to the step S505 until there is no network element in the iLevel _ NEs.
S506: all Level _ NE sets within the allLevel _ NEs are exhaustive.
If the all level _ NEs set still has other device levels and does not belong to the network element set of any ring system, the network element set kLevel _ NEs of another device level and does not belong to any ring system is taken out, and the steps S502 to S506 are repeated until all the network element sets of the device levels in the all level _ NEs set are traversed.
S507: and reporting the analysis result.
And reporting the calculated result to the client, and aiming at each adjustment suggestion, the user can select whether to execute or not, and then clicking a button to execute the selected adjustment to finish the adjustment work. At this point, the detection of the newly added ring is finished.
Taking the example of networking as shown in fig. 7, network element 1 and network element 2 belong to the converged access stratum and both belong to the Sys1 ring system, while network elements 3, 4, 5 belong to access stratum network elements and do not belong to any ring system. At this time, in the method shown in fig. 5:
step S501 obtains a set of access layer network elements that do not belong to any ring system as network elements 3, 4, and 5.
Step S502 selects a set of access stratum network elements, i.e. network elements 3, 4, 5.
Step S503 is to obtain the maximum connection volume of 3- >4- >5 from the network element 3, and obtain Sys1 to add to the RSGm set according to the case 5-3.1 while traversing the network elements 4 and 5.
Step S504 is the result of step S503, and the adjustment proposal is "new ring system" according to the case 5-4.1, and the parent ring is Sys1 and "selection ring system …" in the set of RSGm.
In steps S505 to S506, since only 1 hierarchy does not belong to any ring system set in this example, S502 to S506 do not need to be repeated.
Step S507 reports the new ring detection result, i.e. the network elements 3, 4, and 5 are added to the "new ring system" and the parent ring system is Sys1 to the client.
The specific implementation flow of step S402 is shown in fig. 6, and includes the following steps:
s601: RSi _ NEs and RSi _ Links of the ring system RSi are acquired.
Each ring system is traversed, assuming that it is the ring system RSi that is currently traversed.
And according to all network elements contained in the RSi, marked as RSi _ NEs, obtaining topological Links contained in the network elements, marked as RSi _ Links, wherein two ends of the Link RSi _ Link are required to be network elements in the RSi.
If the number of RSi _ NEs is less than 2, directly traversing the next ring system RSi +1, otherwise executing step S602.
S602: and removing the RSi _ NEs and the RSi _ Links to obtain RSi _ NEs 'and RSi _ Links'.
And removing all network elements with higher levels in the RSi and the related topological Links thereof from the RSi _ NEs and the RSi _ Links to obtain the RSi _ NEs 'and the RSi _ Links'.
Preferably, this step includes the following 4 cases:
6-2.1: the device level of the network elements is only one, and any network elements and topological links do not need to be removed.
6-2.2: if there are only two device levels, the network elements with higher levels and their associated topological Links are removed from RSi _ NEs and RSi _ Links.
6-2.3: if the device levels of the network elements are only three, the network elements at the upper two layers with higher levels and the associated topological Links are removed from RSi _ NEs and RSi _ Links, and meanwhile, the ring system is presented in a ring system with suspicious device level configuration in an interface.
6-2.4: if the device hierarchy of the network elements includes four or more, it is determined that there is an error in the device hierarchy configuration, and the ring system is presented in a "ring system with suspect device hierarchy configuration" in the interface.
The remaining network element sets and topology link sets to be analyzed, which are formed by the results of the above 6-2.1, 6-2.2, and 6-2.3, are respectively denoted as RSi _ NEs 'and RSi _ Links'.
S603: and processing the RSi _ NEs 'and the RSi _ Links' to obtain the connected body ConnEntity.
And traversing and analyzing the connectivity of the dotted line topology formed by the RSi _ NEs 'and the RSi _ Links', and forming N independent connecting bodies ConnEntity-1 … … ConnEntity-N.
Preferably, if N is 1, it is considered as a loop-free split case, and therefore, the following flow is not continued, and the process returns to step S601 again to continue the analysis of the next loop system.
S604: and detecting the connected body ConnEntity-i.
Each formed independent communication body is checked one by one, and if the communication body is currently ConnEntity-i, a link Interlinks between an internal network element of the ConnEntity-i (namely, a network element related to the ConnEntity-i) and an external network element (namely, a network element not related to the ConnEntity-i) is traversed. The link of the network element at only one end of the link, namely the link in the ConnEntity-i, the internal network element of the link is marked as NEin, and the external network element is marked as NEout, includes the following two conditions:
6-4.1: assuming that the device hierarchy of NEout for the link currently traversed to is higher than NEin and that NEout belongs to ring system RSy, RSy is added to RSGm (i.e., the third set of ring systems referred to above, RSGm is initially empty).
Preferably, if the NEout belongs to a plurality of ring systems, these ring systems are all added to the RSGm.
6-4.2: assuming that NEin and neiut of the currently traversed link have the same device hierarchy and neiut belongs to the ring system RSx, RSx is added to RSGk (i.e., the fourth ring system set referred to above, RSGk is initially empty).
Preferably, if the NEout belongs to a plurality of ring systems, these ring systems are all added to the RSGk.
S605: an exhaustive list of all the vias in the ring system RSi.
If the communication link ConnEntity still remains in the ring system RSi and the process of step S604 is not performed, the process of step S604 is repeated for the communication links in a loop until all the communication links in the ring system RSi have been subjected to the process of step S604, and then step S606 is performed.
S606: and processing network elements inside the connected body.
After completing the inter links traversal of all ConnEntity connections in the RSi ring system, the user himself decides to add all network elements of ConnEntity-i to which ring system in the RSGk, or "create a new ring system" or "keep the ring system in the original ring system".
Under the following different scenarios, the default values of the "adjustment suggestion" provided by the network manager to the user are different, for example, the default suggestion of the ConnEntity-i communication is as follows:
6-6.1: if the number of ring systems in the RSGk is greater than 0, the "adjustment proposal" is "incorporate existing ring systems" by default, and all ring systems in the RSGk are listed in the ComboBox of the "ring system", and the option "select ring system …" is additionally added so that the user selects a ring system that is not among the network management recommendations. At this time, "the parent ring system to which the user belongs" is automatically presented according to the ring system selected by the user, and cannot be specified by the user.
6-6.2: if the number of ring systems in RSGk is equal to 0, then the "adjustment proposal" is "create new ring system" by default, at this time, the user must input the name of the ring system to be newly created in "ring system", list all ring systems in RSGm in ComboBox of "affiliated parent ring system", and add the option "ring system selection …" additionally, so that the user can select ring systems that are not in the network management recommendation.
In either case, the user can switch between "incorporate existing ring system", "create new ring system", and "remain in the original ring system" with "adjustment suggestion".
When the 'reserved original ring system' is selected, the 'ring system' is the original ring system, namely the split ring RSi, and the 'belonged parent ring system' is the parent ring system of the original ring system, namely, the 'ring system' and the 'belonged parent ring system' are not changeable.
S607: processing of the sub-ring system of the ring system RSi.
Processing rules for the sub-ring system RSis of the split ring system RSi: if the network element in the sub-ring system has a link connection relationship with the ConnEntity-i, the corresponding sub-ring system is hung under the ring system corresponding to the ConnEntity-i, and the sub-ring system is formed.
If there are a plurality of links satisfying such a condition, the first one found may be the criterion.
S608: an exhaustive list of all ring systems RSi.
If the ring system is still not split, repeating the steps S601-S607, otherwise, performing the step S609.
S609: and reporting the analysis result.
And reporting the calculated result to the client, and aiming at each adjustment suggestion, the user can select whether to execute or not, and then clicking a button to execute the selected adjustment to finish the adjustment work.
Preferably, the processing rules for the split ring system RSi itself are:
if the adjustment suggestion of the communication body existing in the split ring system is reserved in the original ring system, the split ring is still reserved, and the contained network elements are the network element union set of the communication body contained in the original ring system, wherein the adjustment suggestion is reserved;
if the adjustment recommendations for all the connections in the split ring system are not retained in the original ring system and the split ring has no child ring system, then the original ring system is deleted in the process.
Taking the example of networking as shown in fig. 8, network element 1 and network element 2 belong to the converged access stratum and both belong to the Sys1 ring system, while network elements 5, 6, 7, 8, 9 all belong to the access stratum and all belong to Sys 2. At this time, in the method shown in fig. 6:
step S601 traverses Sys2 to obtain RSi _ NEs as network elements 5, 6, 7, 8 and 9, and RSi _ Links as L56, L67 and L89.
Step S602 does not reject any network element and topology link according to the situation 6-2.1.
Step S603 obtains 2 connections, that is, the ConnEntity1 (including the network elements 5, 6, and 7) and the connection ConnEntity2 (including the network elements 8 and 9) through the network element and link calculation obtained in step S602.
Step S604 traverses the connected ConnEntity1, resulting from case 6-4.1 in adding Sys1 to the set of RSGm.
Step S605 repeats step S604, and both RSGm and RSGn of the connected body ConnEntity2 are empty. At this time, the link of Sys2 has already traversed, and step S606 is performed.
Step S606 follows the Sys2 ring system communication ConnEntity1 adjustment suggestion as "create new ring system" and the parent ring system is Sys1 in RSGm or user selection according to scenario 6-6.2. While the adjustment of ConnEntity2 suggests "create new ring system," its parent ring system is selected by the user.
In step S607, the Sys2 ring system does not have a sub ring system, and therefore, no processing is required.
In step S608, if neither of the two link users of the Sys2 ring system selects "remain in the original system", the Sys2 ring system is deleted.
Step S609 continues to repeat steps S601 to S609 for the Sys1 ring system until all ring systems have been subjected to the split processing.
The invention also provides a computer readable storage medium, which stores one or more programs, and the one or more programs are executed to implement all the steps of the ring network management method provided by the invention.
