Detailed ways

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

In the description of the present application, unless otherwise specified, "/" means "or", for example, A/B may mean A or B. The "and/or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and/or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" and "plurality" mean two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

In the SD-OTN technology, the SD-OTN mainly used by communication operators in the early stage is equipment provided by fixed manufacturers (such as equipment manufacturer A), and the networking is completed through the SD-OTN of a single manufacturer. The fiber connection in the manufacturer's network management can directly realize the docking of the port, and the management of the docking port can be realized through the network management system of the manufacturer. With the development of SD-OTN technology, the number of SD-OTN manufacturers is also increasing. In the process of subsequent SD-OTN sinking network coverage, communication operators gradually introduce SD-OTN from multiple manufacturers (different manufacturers). The OTN equipment performs sinking networking coverage. Due to the different network management systems used by different manufacturers, it is impossible to directly realize port connection through fiber connection like the SD-OTN of a single manufacturer. As a result, when managing the remote physical topology corresponding to the SD-OTN line cards of two manufacturers It is inconvenient, which affects the management of SD-OTN interconnection of different manufacturers, especially the management efficiency of line-side card configurations of two manufacturers.

At present, the management (such as configuration monitoring, resource warning, etc.) of different SD-OTN (such as different manufacturers and different models of SD-OTN) equipment needs to be managed manually based on the independent network management provided by each SD-OTN supplier. The (network management) system performs configuration checks, and the realization of each step requires clicking on different network management interfaces. The whole process is cumbersome and boring, and requires a lot of labor and time costs, and the management efficiency is poor. Moreover, when the network connection information is presented in forms such as Excel tables, due to the lack of a visual graphical interface to display the information, the display effect of the information is poor. Moreover, all network configuration information needs to be obtained by manually querying the network management system, which cannot realize real-time monitoring and resource analysis and processing of the network configuration information of the docking port.

For example, the electronic device 11 can obtain SD-OTN network element data by interacting with the coordinator 12, so as to determine whether the SD-OTN docking port matches, so as to realize the Management of SD-OTN interconnection.

The coordinator 12 is used to obtain data. As shown in FIG. 1 , the coordinator 12 interacts with multiple servers 13 to acquire multiple SD-OTN network element data, and transmits the network element data to the electronic device 11 .

The server 13 is used to implement data storage. For example, the server 13 can be the network management server of each SD-OTN supplier (such as each SD-OTN manufacturer), and the network management server of each manufacturer stores the SD-OTN network element data of the manufacturer. .

Exemplarily, for the docking port of the OTN three-mix circuit board, the network state information such as the WDM cross-connect time slot of the port and the number of SDH virtual ports can be obtained; for the SDH docking port and the SDH docking virtual port, the SDH cross-connection of the port can be obtained Network status information such as time slots.

S502. Determine a first resource occupancy rate of the first port according to the network state information of the first port, and determine a second resource occupancy rate of the second port according to the network state information of the second port.

Optionally, the resource occupancy rate may be determined according to the ratio of the actual resources used by the port to the total capacity of the port.

It should be noted that, for different connection methods, due to the different types of resources used, the method of determining the resource occupancy rate will also be different.

Exemplarily, for the docking port of the OTN three-mix circuit board docking, the docking port can be divided into OTU4=100G, OTU2=10G, OTU1=2.5 according to the level rate of the interface type optical transform unit (OTU). G, OTU0=1.25G and other types. Further, the total interface capacity equivalent optical data unit (ODU) ODU0 quantity m is defined, OTU4: m=80, OTU2: m=8, OTU1: m=2, OTU0: m=1.

Further, the number of WDM cross-connect time slots and SDH virtual ports of the port is obtained from the network management server. According to the OTN principle: ODU4=10*ODU2=40*ODU1=80*ODU0, ODUflexKn=n*ODU0, therefore, when calculating the occupancy of WDM time slots, the WDM cross-connect time slots can be converted into equivalent ODU0, the actual occupancy The number of ODU4, ODU2, ODU1, and ODU0 is set to n4, n2, n1, and n0. The number of SDH virtual interfaces is equivalent to ODU2 or ODU1 according to the set STM-N, and the actual occupied number is set to n2x, n1x. The number of ODU0 occupied by ODUflexKn is nk1, nk2, nk3...nkn.

To sum up, the actual equivalent ODU0 occupancy of the docking port, that is, the actual equivalent ODU0n total=n4×80+(n2+n2x)×8+(n1+n1x)×2+n0+nk1+nk2+nk3+ ... nk2; then, for the interface port of the OTN three-mix circuit board, the resource occupancy rate = the actual total equivalent ODU0n/m × 100%.

For SDH docking ports and SDH docking virtual ports, the docking ports can be divided into STM-64=10G, STM-16=2.5G, STM- 4=622M, STM-1=155M and other types. Define the total interface capacity equivalent virtual container (virtual container, VC) 12 as y, STM-64: y=4032, STM-16: y=1008, STM-4: y=252, STM-1: y=63 .

Further, the SDH handover time slot under the port is acquired from the network management server. According to the SDH principle, VC4=63*VC12, VC3=21*VC12, therefore, when calculating the SDH time slot occupancy, the SDH cross-connect time slot can be converted into an equivalent VC12, and the actual number of VC4, VC3, and VC12 can be Set to x4, x3, x12.

To sum up, it can be obtained that the actual equivalent VC12 occupancy of the docking port, that is, the actual equivalent VC12x total=x4×63+x3×21+x12; then for SDH port docking and SDH virtual port, the resource occupancy rate=actual equivalent VC12 x total/y x 100%.

S503. When the first resource occupancy rate is greater than the preset threshold, and/or the second resource occupancy rate is greater than the preset threshold, send warning information.

It should be noted that, for the first port and the second port in a pair of docking ports, the first resource occupancy rate of the first port and the second resource occupancy rate of the second port may be due to the existence of redundant services (discrete services). The occupancy rates are not equal.

Exemplarily, for the first port in a pair of docking ports, there may be a redundant service A, that is, the service only has a corresponding time slot in the first port, and the second port does not involve this service, and the other services are the same In the case of , since redundant service A exists on the first port, the first resource occupancy rate of the first port is higher than the resource occupancy rate of the second port.

Optionally, the preset threshold for sending early warning information can be changed in combination with business requirements, business experience, and the like.

Exemplarily, the preset threshold may be 80%, 75% and so on.

Optionally, the preset threshold of the first port and the preset threshold of the second port may be the same threshold or different thresholds.

In this embodiment of the application, according to different port connection methods, different calculation methods are set to calculate the actual resource occupancy rate of the port, and when the actual resource occupancy rate of the port is greater than the preset threshold, a resource occupancy warning is performed to obtain a resource occupancy From the perspective of SD-OTN to realize the verification management of docking.

Optionally, the timeslot information of each port can be obtained from the SD-OTN network management server corresponding to the port through the coordinator.

Optionally, the ports are connected in different ways, and the time slot information corresponding to the ports is also different.

Exemplarily, for an interface port of an OTN three-mix line board, the time slot information may be a WDM cross-connect time slot; for an SDH interface port or an SDH interface virtual port, the time slot information may be an SDH cross-connect time slot.

Optionally, the time slot information of each port consists of multiple time slots, and each time slot is used to transmit a service.

It should be noted that the time slot information of the two ports corresponds one-to-one, which can be understood as that the time slot exists in both ports, or that the time slot is associated with both ports.

Exemplarily, there is a time slot ODU2:3 under the first port, but it is determined through comparison that there is no time slot ODU2:3 under the second port, so it can be determined that the time slot ODU2:3 under the first port corresponds to The business is a discrete business.
