Description

Technical Field

[0001] The present invention relates to the technical field of transmission resource management, and in particular to a transmission circuit routing automatic concatenation method, system, equipment and medium based on a transmission resource management system. Background Art

[0002] Major operators generally use transmission resource management systems to schedule and record the opened customer services, and then use the corresponding equipment manufacturer's own network management system to configure the network for the services. However, in traditional transmission resource management systems, only the starting point and end point of a single service configuration are recorded, and it is impossible to obtain every route or device port in the middle. When a device port passing through the service fails, the operation and maintenance personnel cannot quickly locate the affected service, resulting in the inability to inform the relevant customers in a timely manner. Therefore, whether it is daily service network layer operation and maintenance monitoring or fault repair, it is essential to associate the transmission circuit in the transmission resource management system with the equipment manufacturer's service route collected by the northbound interface.

[0003] Currently, this association is mainly handled manually, which is not only labor-intensive but also has high learning costs. Operators need to have certain professional knowledge, and association errors are inevitable. When network optimization and other cutovers occur at the network layer, the original associated data will become invalid and need to be manually associated again. This repeated manual work not only increases the cost of network data maintenance, but also increases the probability of operational errors. Summary of the invention

[0004] Aiming at the problem that the transmission resource management system cannot be quickly and automatically associated, resulting in an increase in the cost of network data maintenance and an increase in the probability of operation errors, the present invention proposes a transmission circuit route automatic concatenation method, system, device and medium based on the transmission resource management system; firstly, the working tunnel and the protection tunnel under the pseudo line are obtained; and the complete route is restored according to whether the label exchange is looped; secondly, the circuit complete route sorting is obtained to obtain the circuit segment layer large sorting, and the small sorting under the segment is taken out and added with the prefix of the large segment; then the final sorting is re-performed according to the head end sequence number to obtain the circuit concatenation result; finally, the topological connection is converted into optical layer data to obtain the small sorting of the physical laying layer, and the transmission circuit route concatenation result is obtained by merging; the transmission circuit of the resource system is fully automatically associated, and the real network management route is obtained without manual intervention, which greatly improves the route association of the transmission circuit.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] The professional terms and explanations involved in this embodiment are as follows:

[0043] The northbound interface is an interface for manufacturers or operators to access and manage the network, that is, an interface provided upward.

[0044] PTN (Packet Transport Network) refers to an optical transport network architecture and specific technologies: a layer is set up between IP services and the underlying optical transmission medium. It is designed for the burstiness and statistical multiplexing transmission requirements of packet service traffic. It takes packet services as the core and supports multi-service provision. It has a lower total cost of ownership (TCO) while inheriting the traditional advantages of optical transmission, including high availability and reliability, efficient bandwidth management mechanism and traffic engineering, convenient OAM and network management, scalability, and high security.

[0045] Optical transport network (OTN) is a type of network that implements the transmission, multiplexing, routing, and monitoring of service signals in the optical domain and ensures their performance indicators and survivability.

[0046] Embodiment 1:

[0047] This embodiment provides a transmission circuit routing automatic concatenation method based on a transmission resource management system, which specifically includes the following steps:

[0048] Step S1: According to the obtained port information of the transmission circuit, the working tunnel and the protection tunnel under the pseudo line are obtained.

[0049] The step S1 specifically includes the following steps:

[0050] Step S11: determining the networking type according to the acquired port information at both ends of the transmission circuit, acquiring the ports at both ends of the networking segment and VLAN attributes according to the networking type, and acquiring two Ethernet access points in the same Ethernet service;

[0051] The specific operation of step S11 is: first, obtain the port information at both ends of the transmission circuit, and determine the networking type based on the obtained port information at both ends, then determine whether the networking type is PTN networking or OTN networking. If there are multiple networking types, perform automatic route association and full route restoration section by section, and finally obtain the ports and VLAN attributes at both ends of the networking section based on the networking type, and obtain two Ethernet access points in the same Ethernet service.

[0052] Step S12: locating a pseudo wire carrying the Ethernet access point according to the acquired Ethernet access point.

[0053] Step S13: According to the pseudo wire tunnel bearing relationship, obtain the working tunnel and the protection tunnel in the same protection group as the working tunnel.

[0054] Step S2: Obtain the label exchange list passing through the working tunnel, and determine whether the label exchange is on the ring. If so, obtain the corresponding in-ring routing information of the in-ring device and the out-ring device to restore the complete route. Otherwise, determine whether the device ports are connected in sequence to obtain the complete route.

[0055] The step S2 specifically includes the following steps:

[0056] Step S21: Obtain a list of label exchanges passing through the working tunnel from the working tunnel;

[0057] Step S22: Determine whether each set of label exchanges is included in the ring. If not, the device ports are connected in sequence to obtain a complete route. Otherwise, the in-ring device and out-ring device are obtained according to the adjacent label exchanges of the in-ring and out-ring devices, and the corresponding in-ring routing information is matched and restored to the route.

[0058] Step S3: Obtain the complete routing order of the circuit, take the section with the common site at end A of the circuit as the first section, take end Z as the last section, obtain the circuit section level major order, and take out the minor order under the section and add the prefix of the major section;

[0059] The step S3 specifically comprises the following steps:

[0060] Step S31: The section of the circuit A end sharing the same site is taken as the first section, and the circuit Z end is taken as the last section;

[0061] Step S32: Match the middle segment according to the other ends of the first segment and the last segment, and complete the segment-level sorting of the circuit;

[0062] Step S33: Take out the small sequence under the paragraph and add the prefix of the large paragraph.

[0063] Step S4: re-sort the large sort and the small sort according to the head end sequence number to obtain the circuit series connection result;

[0064] Step S5: Convert the topological connection of the circuit concatenation result obtained by the final sorting into optical layer data to obtain the small sorting of the physical installation layer, and merge them to obtain the transmission circuit routing concatenation result.

[0065] The specific operation of step S5 is: converting the topological connection of the circuit concatenation result obtained by the final sorting into optical layer data, obtaining a small sorting of the physical installation layer, and sorting it according to the optical layer routing, and then performing large sorting and small sorting according to step S3, and merging them to obtain the transmission circuit routing concatenation result.

[0066] Working principle: This embodiment first obtains the working tunnel and protection tunnel under the pseudo line; and obtains the complete route according to whether the label exchange is looped and restored; secondly, the complete route sorting of the circuit is obtained to obtain the large sorting of the circuit segment layer, and the small sorting under the segment is taken out and added to the prefix of the large segment; then the final sorting is re-performed according to the head end sequence number to obtain the circuit concatenation result; finally, the topological connection is converted into optical layer data to obtain the small sorting of the physical laying layer, and merged to obtain the transmission circuit route concatenation result; the transmission circuit of the resource system is fully automatically associated, and the real network management route is obtained without manual intervention, which greatly improves the route correlation of the transmission circuit.

[0067] Embodiment 2:

[0068] This embodiment is based on the above embodiment 1. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a specific embodiment is described in detail.

[0069] In order to solve the problem of fast automatic association of the transmission resource management system, this embodiment provides a transmission circuit routing automatic concatenation method based on the transmission resource management system; after obtaining the port information at both ends of the transmission circuit, first determine whether it is a PTN network or an OTN network according to the routing segment under the transmission circuit. The two implementation principles are different. If there are multiple networking splicing, the routing automatic association and full routing restoration are performed segment by segment. The relationship between the transmission circuit and the routing segment is as follows: Figure 1 As shown, the specific steps include the following steps.

[0070] Step S1: The routing segment under the transmission circuit is the PTN segment. Enter the algorithm of the PTN segment and obtain the port + VLAN used at both ends of the PTN segment. VLAN is an attribute of the port. Since the port can be referenced multiple times by different services, it is recorded through different VLANs to ultimately ensure the uniqueness of the port + VLAN. Two Ethernet access points in the same Ethernet service are obtained, such as Figure 2 shown.

[0071] After locating the two Ethernet access points, the pseudo wire carrying the two Ethernet access points can be located. This pseudo wire is the data that needs to be associated in the PTN segment under this transmission circuit. At this point, the automatic association is completed and the route restoration begins.

[0072] like Figure 3 As shown, through the pseudo line tunnel bearing relationship, the working tunnel can be obtained, and then through the protection tunnel belonging to the same protection group as the working tunnel, all the working + protection tunnels under the pseudo line are finally associated.

[0073] Step S2: Obtain a list of all label exchanges that have passed through the working tunnel, and determine whether each set of label exchanges is included in the ring. Take a label exchange list of 5 devices as an example. If it is not included in the ring, the ports of the 5 devices are connected in sequence, which is the complete route restoration of this tunnel. If the tunnel enters the ring at the second device and exits the ring at the third device, then for the adjacent label exchanges entering and exiting the ring, obtain the entering and exiting devices, match the corresponding in-ring routing information, and restore this part to the route, such as Figure 4 shown.

[0074] like Figure 5 As shown, the complete route of the protection tunnel is restored according to the above steps. Since the working tunnel and the protection tunnel may pass through the same ring, this part needs to be merged and processed to finally form the complete route of the PTN segment under the circuit.

[0075] Step S3: Figure 6 As shown, after obtaining the complete routing order of each section under the circuit, automatic concatenation begins: the section with a common site at the A end of the circuit is identified as the first section, and the Z end is identified as the last section, and the middle section is matched based on the other ends of the first and last sections to complete the large section-level order of the circuit; the small order under the paragraph is taken out, and the prefix of the large paragraph is added, such as the 3-segment route under paragraph 1 is 1-1, 1-2, 1-3, and the 4-segment route under paragraph 2 is 2-1, 2-2, 2-3, 2-4.

[0076] Step S4: re-sort the size order in the previous step to obtain the final circuit connection result. Since each serial number represents a topological connection, it is physically bidirectional and can be connected from left to right and from right to left, so there will be a reverse AZ situation. For example, under the large order 2, it can be connected by 1, 2, 3, 4, or by 4, 3, 2, 1. Therefore, it is necessary to determine whether 2-1 to 2-4 need to be re-sorted based on the beginning and end of paragraph 2. If one end of 2-1 is not equal to the beginning of paragraph 2, it is necessary to find the serial number equal to the beginning of paragraph 2 and re-sort it, as shown in Table 1 below.

[0077] Table 1. Correspondence table of large sorting and small sorting

[0078]

[0079] Rearrange the size order in the previous step to obtain the circuit connection result. Since each serial number represents a topological connection, it is physically bidirectional and can be connected from left to right and from right to left, so there will be a reverse AZ situation. For example, under the large order 2, it can be connected by 1, 2, 3, 4, or by 4, 3, 2, 1. Therefore, it is necessary to determine whether 2-1 to 2-4 needs to be reordered based on the beginning and end of paragraph 2. If one end of 2-1 is not equal to the beginning of paragraph 2, it is necessary to find the serial number equal to the beginning of paragraph 2 and reorder it, as shown in Table 2 below.

[0080] Table 2 The final sorting correspondence table of the first and last equal to the small sorting in paragraph 2

[0081]

[0082] Table 3 The final sorting correspondence table of paragraph 2 where the first and last are not equal to the small sorting

[0083]

[0084]

[0085] The complete order of topological connections under the circuit obtained in the previous step, that is, each of the finally sorted topological connections obtained in the sixth step, is converted into optical layer data one by one to obtain a small sorting of the physical laying layer, and based on the optical layer routing sorting, the size is sorted again according to the principle of step 5.

[0086] Table 4 Final sorting table of physical laying layers

[0087]

[0088] The final sorting of the previous physical laying layers is combined, so that a circuit with three sections can automatically be connected in series to produce a five-level size sorting, and finally obtain the concatenation result of hundreds of physical layer layings.
