Description

Technical Field

[0001] This disclosure relates to the field of communication networks, and in particular to a method and apparatus for creating optical multiplex segments, a network management system, and a box-type wavelength division multiplexing (WDM) device. Background Technology

[0002] Traditional wavelength division multiplexing (WDM) technology is independently managed by each manufacturer. It is generally created by each manufacturer's EMS (electronic manufacturing services) on a board-by-board basis, or by routing method when the network elements of a single site can meet the board resource requirements.

[0003] For high-bandwidth, point-to-point DCI (Data Center Interconnect) scenarios, traditional wavelength division multiplexing (WDM) is difficult to apply due to numerous issues such as size, power consumption, heat dissipation methods, cost, and enclosure. Open and decoupled box-type WDM devices can better meet the needs of DCI scenarios. Summary of the Invention

[0004] The inventors discovered through research that DCI scenarios generally have characteristics such as urgent business needs and rapid expansion. For the configuration management of box-type WDM systems, if the single-site method is used to configure OMS, the manual activation time is long. The routing method has the problem that some manufacturers may need to schedule board resources across network elements due to differences in size and board integration. It is difficult to achieve automatic OMS (Optical Multiplex Section) creation for box-type WDM equipment from multiple manufacturers.

[0005] In view of at least one of the above technical problems, this disclosure provides an optical multiplexer segment creation method and apparatus, a network management system and a box-type wavelength division multiplexing device, which can automatically select along-path boards and port resources, including terminal stations and optical amplifiers, to automatically create optical multiplexers.

[0086] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0087] Figure 1 This diagram illustrates some embodiments of the optical multiplexer segment creation method of this disclosure. Preferably, this embodiment can be executed by the optical multiplexer segment creation apparatus of this disclosure, the network management system of this disclosure, or the cassette wavelength division multiplexing device of this disclosure. The method may include at least one step in step 11 and step 12, wherein:

[0088] Step 11: Select the network cards and port resources along the current network management path to automatically create the optical multiplexing segment. The current network elements include terminal stations and optical amplifiers.

[0089] Step 12: If the cards on the current network element cannot meet the resource requirements, cross-network element scheduling of card resources is allowed.

[0090] In some embodiments of this disclosure, step 12 may include: selecting the along-path cards and port resources of the current network management system for different segments and different protection requirements, and automatically creating optical multiplex segments, wherein different segments include single segments and multiple segments, and different protection requirements include optical multiplex segment protection requirements and no protection requirements.

[0091] The above embodiments of this disclosure can perform cross-network element board resource scheduling. The above embodiments of this disclosure use the routing method to create optical multiplex segments, which can automatically select board and port resources along the way, including terminal stations and optical amplifiers, and allow cross-network element scheduling.

[0092] In some embodiments of this disclosure, the optical multiplexer segment creation method may further include: supporting different board integration levels of the cassette wavelength division multiplexing (WDM) equipment. Figures 2-5 At least one of the four types of OA (Optical Amplifier) ​​boards, wherein:

[0093] 1) A board that integrates a BA (Booster-Amplifier) ​​and a PA (Pre-Amplifier). Figure 2 This is a schematic diagram of an optical amplifier board integrating PA+BA in some embodiments of this disclosure.

[0097] The embodiments disclosed above provide an automatic optical multiplexer segment creation method for cross-network element automatic scheduling of board resources. In open and decoupled multi-vendor optical networks, it can support optical amplifier boards with different integration levels and realize flexible board scheduling.

[0098] Traditional wavelength division multiplexing (WDM) equipment often adopts a siloed management approach, where a single vendor only needs to handle specific board forms. However, due to its open and decoupled characteristics, box-type WDM requires the management of different optical amplifier boards from different vendors. Due to implementation differences, boards with different levels of integration often exist. The scheduling method of the above-described embodiments of this disclosure can support different levels of integration of optical amplifier boards and can support all optical amplifier boards.

If the optical amplifier board resources searched in the current network elements of the first and second terminal stations meet the first constraint condition, and the optical line protection device board resources searched in the current network elements of the first and second terminal stations meet the second constraint condition, then proceed to step 608; otherwise, if the optical amplifier board resources searched in the current network elements of the first and second terminal stations do not meet the first constraint condition, or if the optical line protection device board resources searched in the current network elements of the first and second terminal stations do not meet the second constraint condition, then proceed to step 606.

[0106] Step 607: Determine whether the resources meet the requirements, i.e., determine whether the resources of other network element boards meet the first and second constraints. If the resources of other network element boards in the available network element set meet the first and second constraints, proceed to step 608; otherwise, if the resources of other network element boards in the available network element set do not meet the first and second constraints, proceed to step 613.

[0109] Step 610: Determine if the resources meet the requirements, specifically, determine if the optical amplifier board resources of the current network elements in the first and second terminal stations meet the third constraint condition. If the optical amplifier board resources in the current network elements of the first and second terminal stations meet the third constraint condition, proceed to step 608; if the optical amplifier board resources in the current network elements of the first and second terminal stations do not meet the third constraint condition, proceed to step 611.

[0110] Step 611: Search for other network element board resources in the available network element set.

[0111] Step 612: Determine whether the resources meet the third constraint condition, i.e., whether the resources of other network element boards in the available network element set meet the third constraint condition. If the resources of other network element boards in the available network element set meet the third constraint condition, proceed to step 608; otherwise, if the resources of other network element boards in the available network element set do not meet the third constraint condition, proceed to step 613.

[0112] Step 613: It is determined that the optical multiplexer segment creation failed.

Specifically, determine whether the search for optical amplifier board resources in the current network elements of the first and second terminal stations satisfies the first constraint condition, and whether the search for optical line protection device board resources in the current network elements of the first and second terminal stations satisfies the second constraint condition. If the search for optical amplifier board resources in the current network elements of the first and second terminal stations satisfies the first constraint condition, and the search for optical line protection device board resources in the current network elements of the first and second terminal stations satisfies the second constraint condition, then proceed to step 709; otherwise, if the search for optical amplifier board resources in the current network elements of the first and second terminal stations does not satisfy the first constraint condition, or the search for optical line protection device board resources in the current network elements of the first and second terminal stations does not satisfy the second constraint condition, then proceed to step 707.

[0121] Step 708: Determine whether the resources meet the requirements, i.e., determine whether the resources of other network element boards meet the first and second constraints. If the resources of other network element boards in the available network element set meet the first and second constraints, proceed to step 709; otherwise, if the resources of other network element boards in the available network element set do not meet the first and second constraints, proceed to step 717.

[0122] Step 709: Search for board resources in the set of available network elements of each optical amplifier station along the route: the board must meet the requirement of 2 ILAs.

[0123] In some embodiments of this disclosure, for OMS protection, the primary and backup paths are allowed to have different optical amplifier stations (i.e., different optical cable paths), but for bidirectional optical fibers on the same path, amplification is required in the same optical amplifier board (including ILA*2).

[0124] Step 710: Determine if the resource requirements are met, i.e., determine if the bidirectional optical fibers on the same path can be amplified in the same optical amplifier board. If the bidirectional optical fibers on the same path can be amplified in the same optical amplifier board, proceed to step 711; otherwise, if the bidirectional optical fibers on the same path do not meet the requirements for amplification in the same optical amplifier board, proceed to step 717.

[0128] Step 714: Determine if the resources meet the requirements, specifically, determine if the optical amplifier board resources of the current network elements in the first and second terminal stations meet the third constraint condition. If the optical amplifier board resources in the current network elements of the first and second terminal stations meet the third constraint condition, proceed to step 709; if the optical amplifier board resources in the current network elements of the first and second terminal stations do not meet the third constraint condition, proceed to step 715.

If the resources of other network element boards in the available network element set meet the third constraint condition, proceed to step 709; otherwise, if the resources of other network element boards in the available network element set do not meet the third constraint condition, proceed to step 717.

[0131] Step 717: It is determined that the optical multiplexer segment creation failed.

[0147] Figure 8 The diagram illustrates further embodiments of the optical multiplexer segment creation method of this disclosure. Preferably, this embodiment can be executed by the optical multiplexer segment creation apparatus of this disclosure, the network management system of this disclosure, or the cassette wavelength division multiplexing device of this disclosure. The method may include at least one step of steps 81-85, wherein:

[0148] Step 81: Obtain the available network element resources of the relevant sites.

[0149] Step 82: Obtain network element information for each network element, wherein the network element information includes information such as module information and port availability.

[0150] Step 83, according to business requirements, follow any of the above embodiments (e.g.) Figures 1-7 The optical multiplexer segment creation method described in any embodiment is used to schedule the required segment resources.

[0151] Step 84: Obtain connection information between network elements.

[0152] Step 85: Connect the scheduled plate resources at the port level to form an optical multiplexer segment.

[0153] The embodiments of this disclosure enable cross-network element board resource scheduling. Since box-type WDM equipment differs from traditional WDM equipment, its stackable design also imposes size limitations. When board resources for a single network element are limited, the embodiments of this disclosure propose a cross-network element board resource scheduling method that can include all network element boards that meet availability conditions in the same site into a board resource pool for unified scheduling.

Figure 9 As shown, the optical multiplexer segment creation apparatus of this disclosure may include a multiplexer segment creation module 91 and a segment scheduling module 92, wherein:

[0155] The multiplex segment creation module 91 is used to select the cards and port resources along the current network management path and automatically create optical multiplex segments. The current network elements include terminal stations and optical amplifiers.

[0156] The board scheduling module 92 is used to allow cross-network element scheduling of board resources when the board on the current network element cannot meet the resource requirements.

[0157] In some embodiments of this disclosure, the optical multiplexer segment creation apparatus can be used to support at least one of the following four types of optical amplifier boards, depending on the different board integration levels of the box-type wavelength division multiplexing equipment: boards that integrate power amplifiers and preamplifiers, boards that contain only power amplifiers, boards that contain only preamplifiers, and optical line amplifier boards that contain bidirectional erbium-doped fiber amplifiers.

[0158] The above embodiments of this disclosure can perform cross-network element board resource scheduling. The above embodiments of this disclosure use the routing method to create optical multiplex segments, which can automatically select board and port resources along the way, including terminal stations and optical amplifiers, and allow cross-network element scheduling.

[0159] The embodiments disclosed above provide an automatic optical multiplexer segment creation method for cross-network element automatic scheduling of board resources. In open and decoupled multi-vendor optical networks, it can support optical amplifier boards with different integration levels and realize flexible board scheduling.

[0160] Traditional wavelength division multiplexing (WDM) equipment often adopts a siloed management approach, where a single vendor only needs to handle specific board forms. However, due to its open and decoupled characteristics, box-type WDM requires the management of different optical amplifier boards from different vendors. Due to implementation differences, boards with different levels of integration often exist. The scheduling method of the above-described embodiments of this disclosure can support different levels of integration of optical amplifier boards and can support all optical amplifier boards.
