Fig. 2 is a schematic diagram of an architecture of an existing optical transport network, and as shown in fig. 2, a wavelength division Multiplexer (MUX), an optical amplifier, an Optical Add Drop Multiplexer (OADM), and a wavelength division Demultiplexer (DeMUX) are disposed between a transmitting end (Tx) and a receiving end (Rx), an OMS layer is a single-layer structure, and may include a plurality of OMS segments, where different OMS segments are in a serial relationship, and a fault point of different OMS segments can be accurately located by using existing monitoring management.

However, as the traffic of optical transport networks increases, many other optical layer multiplexing technologies are emerging in the field of optical transport, such as: an Optical Code Division Multiplexing (OCDM) technology, an Optical time-Division multiplexing (OTDM) technology, and so on, when a plurality of Optical layer multiplexing technologies are used in an Optical transport network for superposition and nesting, an OMS layer is usually a multilayer nested structure, fig. 3 is an architecture schematic diagram of an Optical transport network supporting superposition of the existing multilayer multiplexing technologies, as shown in fig. 3, at this time, the existing monitoring design cannot accurately identify which layer of OMS a fault point is, and thus, the positioning accuracy of the OMS fault point in the Optical transport network adopting the plurality of Optical layer multiplexing technologies is low.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The terms "first," "second," "third," "fourth," and the like in the description and in the claims, as well as in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 3 is a schematic diagram of an architecture of an optical transport network supporting superposition of multiple layers of multiplexing technologies in the prior art, and as shown in fig. 3, a code division MUX, a wavelength division MUX, an optical amplifier, an OADM, a wavelength division DeMUX, and a code division DeMUX are disposed between TX and RX, and the optical transport network adopts two optical layer multiplexing technologies of OCDM and WDM for superposition and nesting, and at this time, two nested OMS layers exist in the optical transport network.

By adopting the existing monitoring design, if the fiber is broken at the point A, because the wavelength division MUX is a source point of the OMS and the OMS is not detected at the input port, the OMS alarm information cannot be inserted, so that the OMS signal loss can be detected at the point B, which is completely the same as the fiber broken at the point B, and therefore, the existing monitoring design cannot distinguish whether the fiber is broken at the point A or the fiber is broken at the point B, and the fault point cannot be accurately positioned.

The OMS elastic networking method, the device and the system provided by the embodiment of the invention are suitable for a scene in which a plurality of optical layer multiplexing technologies are adopted for superposition nesting in an optical transport network, and at the moment, an OMS layer in the optical transport network is of a multilayer nested structure. By the OMS elastic networking method, the device and the system provided by the embodiment of the invention, when a fault point occurs in the optical transport network, the OMS to which the fault point belongs can be accurately positioned, the positioning accuracy of the fault point of the OMS is improved, and the reliable transmission of services is ensured.

Example one

Fig. 4 is a schematic structural diagram of an OMS elastic networking device according to an embodiment of the present invention, and as shown in fig. 4, the OMS elastic networking device according to the embodiment of the present invention is applied to an OMS elastic networking system, where the OMS elastic networking system may include at least two optical multiplexing units, and the OMS elastic networking device may include: a control unit 11 and at least one light multiplexing unit 12.

The control unit 11 is configured to:

and determining a client layer/server layer relation between the first OMS and the second OMS according to the OMS indication information respectively corresponding to the first OMS and the second OMS.

Determining a function reference point of the first OMS according to the client layer/server layer relationship, and generating information of the function reference point of the first OMS. The information of the functional reference point of the first OMS is sent to the optical multiplexing unit 12 corresponding to the first OMS.

The optical multiplexing unit 12 corresponding to the first OMS is configured to:

and managing the first OMS according to the information of the function reference point of the first OMS.

And the OMS indication information is used for indicating the hierarchy attribute of the corresponding OMS.

Specifically, the OMS elastic networking device is applied to an OMS elastic networking system, where the OMS elastic networking system includes at least two optical multiplexing units, one optical multiplexing unit corresponds to one OMS, and the at least two optical multiplexing units may adopt multiple optical multiplexing technologies. Fig. 5 is a schematic functional architecture diagram of an optical transport network according to an embodiment of the present invention, and as shown in fig. 5, at least two OMS layers allow multiple optical multiplexing technologies to be used in a nested manner.

Because the OMS elastic networking device includes the control unit 11 and the at least one optical multiplexing unit 12, if the OMS elastic networking device includes the at least two optical multiplexing units 12, the OMS elastic networking system includes the at least one OMS elastic networking device, and if the OMS elastic networking device includes only one optical multiplexing unit 12, the OMS elastic networking system includes the at least two OMS elastic networking devices. The structure of at least two OMS elastic networking devices in the OMS elastic networking system can be the same or different.

One optical multiplexing unit 12 in the OMS elastic networking device determines a first OMS, and another optical multiplexing unit 12 in the OMS elastic networking device, or one optical multiplexing unit in another OMS elastic networking device in the OMS elastic networking system determines a second OMS, that is, two optical multiplexing units that determine the first OMS and the second OMS may be located in the same OMS elastic networking device, or may be located in two OMS elastic networking devices, respectively. The first OMS and the second OMS are located in different layers and are adjacent to each other, for two OMSs nested adjacent to each other in the layers, the OMS located at the upper layer can be called as an upper-layer OMS or a client layer, and the OMS located at the lower layer can be called as a lower-layer OMS or a server layer.

Because the OMS indication information of the first OMS indicates the hierarchy attribute of the first OMS, and the OMS indication information of the second OMS indicates the hierarchy attribute of the second OMS, according to the respective OMS indication information corresponding to the first OMS and the second OMS, the control unit 11 may determine a client layer/server layer relationship between the first OMS and the second OMS, that is, determine a hierarchy nesting relationship between the first OMS and the second OMS.

The control unit 11 may determine a function reference point of the first OMS according to a client layer/server layer relationship between the first OMS and the second OMS, and generate information of the function reference point of the first OMS. Wherein the information of the function reference point of the first OMS may indicate a type and/or a location of the function reference point of the first OMS, and the control unit 11 sends the information of the function reference point of the first OMS to the optical multiplexing unit 12 corresponding to the first OMS.

It should be noted that, there are various ways for the control unit 11 to generate the information of the function reference point of the first OMS, for example: the information of the function reference point of the first OMS can be automatically generated according to OMS indication information input by a manual or other OMS elastic networking device or other independent control units and the like and according to the type of the optical multiplexing unit corresponding to the first OMS and/or the second OMS; or automatically analyzing the information of the function reference point of the first OMS which is input by hand or other OMS elastic networking devices or other independent control units and has a mark for marking the relation between the first OMS and the second OMS client layer/service layer into the information of the function reference point of the first OMS which can be identified by the optical multiplexing unit corresponding to the first OMS; or according to the information of the function reference point input by hand or other OMS elastic networking devices or other independent control units and the like, the information of the function reference point of the first OMS which can be identified by the optical multiplexing unit corresponding to the first OMS is converted according to the client layer/server layer relation between the first OMS and the second OMS, and the like.

The optical multiplexing unit 12 corresponding to the first OMS may obtain the type and the position of the function reference point of the first OMS according to the information of the function reference point of the first OMS, and further, may manage the first OMS according to the information of the function reference point of the first OMS. For example: the insertion or detection of connection supervision or maintenance information of the first OMS may be performed according to a functional reference point of the first OMS.

It can be seen that, the OMS elastic networking device provided in the embodiment of the present invention is applied to a scenario in which an OMS layer has at least two layers of nested OMS layers in an optical network, the control unit 11 may determine a function reference point exclusive to a first OMS, and generate information of the function reference point of the first OMS, and the optical multiplexing unit 12 corresponding to the first OMS may manage the first OMS according to the information of the function reference point of the first OMS.

In addition, because the client layer/server layer relationship between the first OMS and the second OMS can be determined in the OMS elastic networking device according to the OMS indication information corresponding to the first OMS and the second OMS respectively, the OMS elastic networking device can conveniently change the client layer/server layer relationship between different OMSs, and can also conveniently add OMSs supporting a new type or delete OMSs supporting a certain type, so that the workload is small, the compatibility is good, and the influence on the system is small. For example, the OMS flexible networking device can conveniently change an OCDM over OTDM (the OMS using the OCDM technology is a client layer of the OMS using the OTDM technology) to an OTDM over OCDM (the OMS using the OTDM technology is a client layer of the OMS using the OCDM technology), without changing a device corresponding to an OMS using another technology (i.e. except for using the OCDM and the OTDM technology). In contrast, when the client layer/server layer relationship between different OMS is fixedly set, if the client layer/server layer relationship between different types of OMS needs to be changed, or a new type of OMS is supported, or a type of OMS is supported is deleted, the management or control design in the system needs to be changed, the design of almost all devices in the system needs to be changed, the workload is high, the influence on the system is wide, in many systems which are already started to operate, the change is almost unacceptable, and the corresponding standard, for example, ITU-T g.872, needs to be changed, and the change of the standard usually takes years. The OMS elastic networking device provided by the embodiment of the invention can well avoid the problems.

It should be noted that the OMS elastic networking device includes at least one optical multiplexing unit, where an OMS determined by one optical multiplexing unit is referred to as a first OMS, and of course, other optical multiplexing units may also exist in the OMS elastic networking device, and OMS determined by other optical multiplexing units may also belong to the first OMS, that is, the OMS elastic networking device may determine a plurality of first OMS, or may determine only one first OMS. For each first OMS determined by the OMS elastic networking device, the first OMS may be managed by the OMS elastic networking device provided in the embodiment of the present invention. Specifically, if the OMS elastic networking device only includes one optical multiplexing unit, only one first OMS is determined, at this time, at least one optical multiplexing unit in at least one other OMS elastic networking device in the OMS elastic networking system determines a second OMS, and the second OMS is nested and adjacent to the first OMS. If the OMS elastic networking device comprises at least two optical multiplexing units, only at least two first OMSs can be determined, or at least one first OMS and at least one second OMS are determined; if the OMS determined by the OMS elastic networking device belongs to the first OMS, at the moment, at least one optical multiplexing unit in at least one other OMS elastic networking device in the OMS elastic networking system determines a second OMS; if the OMS elastic networking device determines at least one first OMS and at least one second OMS, no requirement is made on whether other elastic networking devices exist in the OMS elastic networking system, and no requirement is made on whether the first OMS or the second OMS is determined by other elastic networking devices.

Optionally, the light multiplexing unit 12 includes at least one of the following: optical multiplexer, optical demultiplexer, optical add/drop multiplexer.

Among these, an optical multiplexer is one of the key devices in an optical network, and is used to multiplex multiple optical signals into one OMS optical signal, and generally includes a number of inputs and a single output. In the prior art, because only one layer of OMS exists, the input multipath optical signals are actually OCh signals. In the embodiment of the present invention, since the multiple layers of OMS are allowed to be stacked and nested, the input multiple optical signals may be OCh signals or upper layer OMS signals, and when the input multiple optical signals are the upper layer OMS signals, the output multiple optical signals are lower layer OMS signals. In the prior art, the OMS employs a wavelength multiplexing technique, in which case, an optical multiplexer, also called a multiplexer, is used to multiplex a plurality of single-wavelength optical signals (OCh signals) into one-wavelength multiplexed optical signal (OMS signal).

An optical demultiplexer corresponds to an optical multiplexer and is used to demultiplex a single OMS optical signal into multiple optical signals, and generally includes a single input and a number of outputs. In the prior art, because only one layer of OMS exists, the output multipath optical signal is actually an OCh signal. In the embodiment of the present invention, since the multiple layers of OMS are allowed to be stacked and nested, the output multipath optical signal may be an OCh signal or an upper layer OMS signal, and when the output is the upper layer OMS signal, the input is a lower layer OMS signal. In the prior art, the OMS employs a wavelength multiplexing technique, in which an optical demultiplexer is also called a demultiplexer, and is used to demultiplex one-path multiplexed optical signal (OMS signal) into a plurality of optical signals (OCh signals) with single wavelength.

An optical Add/Drop multiplexer is one of the key devices in an optical network, and has the function of selectively sending a lower optical path (Drop) and/or an upper optical path (Add) OCh signal or an upper OMS signal from a transmission optical path, and simultaneously not influencing the transmission of other OCh signals or upper OMS signals. It is simply understood that the optical add/drop multiplexer is equivalent to an optical demultiplexer plus an optical multiplexer, so that the functions implemented by the optical add/drop multiplexer can refer to the descriptions of the optical demultiplexer and the optical multiplexer, and are not described in detail.

Optionally, the OMS elastic networking device may be used for unidirectional transmission or bidirectional transmission. When the OMS elastic networking device is used for unidirectional transmission, the transmission directions of the first OMS signal and the second OMS signal are the same; when the OMS elastic networking device is used for bidirectional transmission, a plurality of first OMS may exist in the OMS elastic networking system, and the transmission directions of the first OMS signals are opposite, and similarly, a plurality of second OMS may also exist in the OMS elastic networking system, and the transmission directions of the second OMS signals are opposite.

Optionally, the functional reference point of the first OMS comprises at least one of: a Terminal Connection Point (TCP), a Multipoint Connection Point (MPCP), an Access Point (AP), and a Connection Point (CP).

The definition of TCP, MPCP, AP and CP can be referred to the specification of International Telecommunication Union Telecommunication standard bureau (ITU-T) g.872.

Optionally, managing the first OMS may include: at least one of fault management, performance management, and configuration management is performed on the first OMS.

For the definition of fault management, performance management and configuration management of the OMS, reference may be made to the specification of the standard ITU-T g.872.

Optionally, the OMS indication information may include: OMS priority or OMS type. Wherein the OMS priority is used to indicate the level of the OMS. The OMS type is used to indicate the type of optical multiplexing employed by the OMS.

Optionally, a preset corresponding relationship exists between the OMS priority and the OMS type.

Specifically, the OMS priority is used to indicate the hierarchy where the OMS is located, and the higher the OMS priority is, the higher the hierarchy of the OMS corresponding to the OMS is.

The OMS indication information is explained in detail below by specific examples.

For example: the OMS indication information comprises OMS priority, the OMS priority is represented by a combination of letters and numbers, and the lower the number is, the higher the OMS priority is. The OMS priority of the first OMS is OMS-1, the OMS priority of the second OMS is OMS-2, and OMS-1 is prior to OMS-2, so that the first OMS is positioned at the upper layer of the second OMS.

It should be noted that, in the embodiment of the present invention, a specific implementation manner of the OMS priority is not particularly limited, as long as a level where the OMS is located is indicated. For example: the OMS priority may be represented by a number, the number may be an integer or a decimal, and the higher the number, the higher the priority, or the lower the number, and so on.

It should be noted that, in the embodiment of the present invention, the OMS priority indicates a hierarchy where the OMS is located, and the hierarchy of the OMS may be a hierarchy of the OMS in all OMS in the OMS elastic networking device, or may be a hierarchy of the OMS in all OMS in the OMS elastic networking system, which is not particularly limited in this embodiment of the present invention, and is set as needed.

Another example is: the OMS indication information includes an OMS type, where the optical multiplexing type used by the first OMS is OCDM, the OMS type of the first OMS may be OMS-CDM, the optical multiplexing type used by the second OMS may be WDM, and the OMS type of the second OMS may be OMS-WDM. If OMS-CDM is preset to OMS-1 and OMS-WDM to OMS-2, the first OMS is located at the upper layer of the second OMS.

It should be noted that, the embodiment of the present invention does not particularly limit the specific implementation manner of the OMS type, as long as the optical multiplexing type adopted by the OMS is indicated.

It should be noted that, the embodiment of the present invention is not particularly limited to the specific implementation technology of the optical multiplexing type, for example: the optical Multiplexing type may be OCDM, OTDM, Space Division Multiplexing (SDM), Orbital Angular Momentum Multiplexing (OAM), or WDM, etc.

Optionally, the control unit 11 is specifically configured to:

and if the OMS priority of the first OMS is higher than that of the second OMS, determining the first OMS as a client layer of the second OMS, and determining the second OMS as a server layer of the first OMS.

And if the first OMS is the server layer of the second OMS, determining a function reference point of the first OMS in the coverage range of the first OMS.

Specifically, for two OMS nested adjacently in a hierarchy, the function reference point of the client layer is located between the coverage areas of the client layer and the server layer, and the function reference point of the server layer is located in the coverage area of the server layer.

Therefore, for two OMSs which are nested in a hierarchy and adjacent to each other, the position of the exclusive function reference point of the OMS can be determined according to whether the OMS is a client layer or a server layer, so that when a fault occurs in an optical network, the position of the fault point on which OMS layer can be accurately positioned, the positioning accuracy of the fault point is improved, and the reliable transmission of services is ensured.

Optionally, the management information used when the first OMS is managed according to the information of the function reference point of the first OMS is marked by adding OMS indication information of the first OMS.

Specifically, management information is used when the first OMS is managed, the management information is marked by adding OMS indication information of the first OMS, when a fault occurs in the optical network, whether the fault point belongs to the first OMS can be accurately known through the management information, the locating efficiency of the fault point is further improved, and therefore reliable transmission of services is further guaranteed.

The management information used when managing the first OMS may include connection supervision information and maintenance information of the OMS, for example: loss of Signal (LOS), Backward Defect Indication (BDI), Forward Defect Indication (FDI), load Loss Indication (PMI), and so on.

The management information of the OMS is explained in detail below by a specific example.

For example: if the OMS priority of the first OMS is OMS-1, the LOS, BDI, FDI, and PMI of the first OMS may be labeled OMS-1-LOS, OMS-1-BDI, OMS-1-FDI, and OMS-1-PMI, respectively.

Another example is: if the OMS type of the first OMS is OMS-CDM, the LOS, BDI, FDI, and PMI of the first OMS may be labeled OMS-CDM-LOS, OMS-CDM-BDI, OMS-CDM-FDI, and OMS-CDM-PMI, respectively.

When the management information used for managing the first OMS is marked by adding the OMS indication information of the first OMS, the complete OMS indication information of the first OMS may be added, or only a part of the OMS indication information of the first OMS may be added for marking, so long as the management information can indicate which OMS layer the management information corresponds to, and the OMS layer may be a client layer or a server layer.

It should be noted that, the specific types of other devices in the optical network are not particularly limited in the embodiments of the present invention. For example: the method can be a control unit in other OMS elastic networking devices in the optical network, or a total control unit in the optical network, and the like.

It should be noted that, in the embodiment of the present invention, a specific implementation manner of the OMS configuration information is not particularly limited, and may be different according to a sending device. For example: if the sending device is a master control unit in the optical network, the OMS configuration information may be OMS indication information configured by the master control unit for the first OMS, or may be OMS indication information of OMS corresponding to other OMS elastic networking devices in the optical network; if the sending device is a control unit in another OMS elastic networking device in the optical network, the OMS configuration information may be OMS indication information of an OMS corresponding to the other OMS elastic networking device in the optical network.

It should be noted that, there may be a variety of implementation manners by adding the OMS indication information to the first OMS according to the OMS configuration information, and the embodiment of the present invention is not particularly limited. For example: the control unit may directly determine and add the OMS indication information of the first OMS according to the OMS configuration information, or may determine and add the OMS indication information of the first OMS after performing multiple information interaction negotiations with other devices in the optical network.

Optionally, the control unit is specifically configured to:

Alternatively, the first and second electrodes may be,

And converting the OMS type of the second OMS into the OMS priority of the second OMS according to the corresponding relation between the OMS type and the OMS priority.

Optionally, the control unit is further configured to:

information of a functional reference point of the second OMS is obtained.

Specifically, the second OMS is nested and adjacent to the first OMS in a hierarchical manner, and by acquiring the information of the function reference point of the second OMS, when a fault occurs in the optical network, whether the fault point belongs to the first OMS or the second OMS can be further determined according to the information of the function reference point of the second OMS, so that the positioning accuracy of the fault point is further improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.

Optionally, the information of the function reference point of the second OMS is used to indicate a type and/or a location of the function reference point of the second OMS.

An optical multiplexing unit corresponding to the second OMS is configured to:

and managing the second OMS according to the information of the function reference point of the second OMS.

Specifically, if the optical multiplexing unit corresponding to the first OMS and the optical multiplexing unit corresponding to the second OMS belong to the same OMS elastic networking device, it is described that the optical multiplexing unit corresponding to the second OMS is also arranged in the OMS elastic networking device, so that the control unit may determine a dedicated function reference point of the second OMS according to the client layer/server layer relationship, and generate information of the function reference point of the second OMS, and then the optical multiplexing unit corresponding to the second OMS may obtain a position or a type of the function reference point of the second OMS according to the information of the function reference point of the second OMS, and further may manage the second OMS according to the information of the function reference point of the second OMS. Therefore, when a fault occurs in the optical network, whether the fault point belongs to the second OMS can be determined, the fault point of the second OMS cannot be judged as the fault point of other OMS by mistake, the positioning accuracy of the fault point is further improved, the network maintenance efficiency is improved, and the reliable transmission of services is guaranteed.

Optionally, the control unit is further configured to:

and determining an alarm suppression relation between the first OMS and the second OMS according to the relation of the client layer and the server layer.

Specifically, the first OMS and the second OMS are in a hierarchical nesting relationship, so some alarms at the server layer generally cause signal impairment at the client layer. Accordingly, for some alarms at the client layer, signal interruption at the server layer may also result, i.e., one failure point may correspond to different alarms at the client layer and the server layer. For example: if the alarm is generated at the server layer, which usually means that the device or unit corresponding to the server layer fails, it is not necessary to generate the associated alarm at the client layer, because if the associated alarm is generated at the client layer, the management system or the administrator may misunderstand that the device or unit corresponding to the client layer fails, which may cause the fault to be incorrectly positioned. Therefore, the alarm suppression relationship between the first OMS and the second OMS can be determined according to the client layer/server layer relationship, that is, only one of the management information of the first OMS and the management information of the second OMS which indicate the same fault is reserved, so that repeated alarm or associated alarm in the optical network can be avoided, the marking and maintenance of the alarm information in the optical network are facilitated, the fault location of the optical network system is facilitated, and the maintenance efficiency of the optical network is improved.

It should be noted that, in the embodiment of the present invention, if the optical multiplexing unit corresponding to the first OMS and the optical multiplexing unit corresponding to the second OMS all belong to the same OMS elastic networking device, the operation of the first OMS is also applicable to the second OMS, and the principle is similar.

The embodiment of the invention provides an OMS elastic networking device. According to the OMS elastic networking device provided by the embodiment of the invention, when a fault occurs in the optical network, whether the fault point belongs to the first OMS can be determined, so that the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.

EXAMPLE III

Fig. 6 is a schematic structural diagram of an OMS elastic networking device according to a third embodiment of the present invention, and the third embodiment of the present invention provides a specific implementation manner of the OMS elastic networking device on the basis of the first and second embodiments of the above-mentioned device. As shown in fig. 6, an OMS elastic networking apparatus provided in an embodiment of the present invention may include: the optical multiplexing device comprises a controller and four optical multiplexing units, wherein the four optical multiplexing units are respectively as follows: an optical multiplexer 1, an optical multiplexer 2, an optical demultiplexer 1 and an optical demultiplexer 2.

Wherein, the optical multiplexer 1 and the optical multiplexer 2 are used for east transmission, and the optical demultiplexer 1 and the optical demultiplexer 2 are used for west transmission.

The optical multiplexer 1 and the optical demultiplexer 1 use OCDM technology, and the optical multiplexer 2 and the optical demultiplexer 2 use WDM technology.

In an embodiment of the invention, the controller identifies OMS types of different types of OMS as OMS-CDM and OMS-WDM, respectively, where OMS-CDM corresponds to OCDM and OMS-WDM corresponds to WDM.

The controller may also directly identify different types of OMSs using OMS priorities, such as OMS using OCDM technology as OMS-1 and OMS using WDM technology as OMS-2, where OMS-1 and OMS-2 are OMS priorities and OMS-1 takes precedence over OMS-2.

Wherein the dashed arrows in fig. 6 indicate that information interaction is implemented between the controller and other devices.

For east transmission, if the optical multiplexer 1 corresponds to a first OMS (OMS-CDM/OMS-1), the optical multiplexer 2 corresponds to a second OMS (OMS-WDM/OMS-2), and it can be determined according to the OMS indication information that the first OMS (OMS-CDM/OMS-1) is a client layer of the second OMS (OMS-WDM/OMS-2) and the second OMS (OMS-WDM/OMS-2) is a server layer of the first OMS (OMS-CDM/OMS-1).

Taking the determination of TCP as an example, since the first OMS (OMS-CDM/OMS-1) is the client layer of the second OMS (OMS-WDM/OMS-2), the TCP point of the first OMS (OMS-CDM/OMS-1) is determined between the coverage of the first OMS (OMS-CDM/OMS-1) and the second OMS (OMS-WDM/OMS-2), i.e., the A point is determined between "optical multiplexer 1" and "optical multiplexer 2". Since the second OMS (OMS-WDM/OMS-2) is the server layer of the first OMS (OMS-CDM/OMS-1), the C point is determined to be the TCP point of the second OMS (OMS-WDM/OMS-2) within the coverage of the second OMS (OMS-WDM/OMS-2), i.e., on the east side of the "optical multiplexer 2".

Similarly, for Western-wise transmission, it may be determined from the client layer/server layer relationship that X point is the TCP point of OMS-CDM/OMS-1 and Z point is the TCP point of OMS-WDM/OMS-2.

Further, the management information of OMS can be marked by OMS indication information, and the LOS, BDI, PMI and FDI of OMS-CDM/OMS-1 can be marked as OMS-1-LOS, OMS-1-BDI, OMS-1-PMI and OMS-1-FDI respectively by applying OMS priority, and the LOS, BDI, PMI and FDI of OMS-WDM/OMS-2 can be marked as OMS-2-LOS, OMS-2-BDI, OMS-2-PMI and OMS-2-FDI respectively.

For example, if OMS-1-LOS is detected by point X, then OMS-1-BDI is inserted back upstream (since optical demultiplexer 1 is used for west-oriented transmission, for point X, the upstream insertion of OMS-1-BDI should be an east insertion of OMS-1-BDI); inserting OMS-1-PMI downstream if OMS-1-LOS is detected at Point A (since optical multiplexer 1 and optical multiplexer 2 are used for east transmission, for Point A, inserting OMS-1-PMI downstream should be inserting OMS-1-PMI east); inserting OMS-2-BDI back upstream if OMS-2-LOS is detected at point Z (since optical demultiplexer 2 is used for west-wise transmission, inserting OMS-2-BDI back upstream should be inserting OMS-2-BDI east for point Z); OMS-2-PMI is inserted downstream if OMS-2-LOS is detected at C point (since optical multiplexer 2 is used for east transmission, for C point, inserting OMS-2-PMI downstream should be inserting OMS-2-PMI east).

Further, an alarm suppression relationship between OMS-CDM/OMS-1 and OMS-WDM/OMS-2 may be determined.

For example, OMS-2-FDI may be inserted if OMS-2-LOS is detected at point Z, so that an alarm of OMS-1-LOS will not be generated based on the alarm of OMS-2-FDI when no light is detected at point X.

The embodiment of the invention provides an OMS elastic networking device, in particular a specific implementation mode of the OMS elastic networking device, wherein OMS allows two optical multiplexing technologies of OCDM and WDM to be used in a nested mode. According to the OMS elastic networking device provided by the embodiment of the invention, when a fault occurs in the optical network, whether the fault point belongs to the first OMS can be determined, so that the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.

Therefore, in the OMS elastic networking device provided in the embodiment of the present invention, the control unit may determine the dedicated function reference point of the OCh, so that when a fault occurs in the optical network, it may be determined whether the fault point belongs to the OCh, and the fault point of the OCh is not misjudged as a fault point of another functional layer, so that the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of the service is ensured.

Alternatively, the light emitting unit 13 may be an optical transmitter, and the light receiving unit 14 may be an optical receiver.

Among them, the optical transmitter is one of the key devices in the optical network, and is used to modulate data onto an optical carrier to form an optical signal (generally, an OCh signal). The optical receiver corresponds to the optical transmitter and receives an optical signal (typically an OCh signal) from which data is recovered.

Optionally, managing the OCh may include: and performing at least one of fault management, performance management and configuration management on the OCh.

The definition of the functional reference point of OCh can be found in the specification of ITU-T G.872 standard.

Optionally, the control unit 11 is specifically configured to:

determining the top OMS of all OMSs in the optical network according to the relation of a client layer/a server layer between the OMSs. Wherein, the upper layer OMS is a client layer of the next lower layer OMS.

The functional reference points of the OCh are determined within the coverage of the OCh and outside the coverage of the top OMS.

Specifically, the function reference point of the OCh is located between the coverage of the OCh and the top OMS.

The OMS elastic networking device provided by the embodiment of the invention is applied to an OMS elastic networking system, and the OMS elastic networking system comprises any one of the following unit combinations: at least two optical multiplexing units and at least one light emitting unit; at least two optical multiplexing units and at least one optical receiving unit; at least two optical multiplexing units, at least one light emitting unit, and at least one light receiving unit.

That is, the OMS elastic networking apparatus in the embodiment of the present invention, as shown in fig. 7, may specifically include any one or more of at least one light emitting unit, at least one light receiving unit, and at least one light multiplexing unit, and a control unit.

EXAMPLE five

Fig. 8 is a schematic structural diagram of an OMS elastic networking device according to a fifth embodiment of the present invention, and the embodiment of the present invention provides another specific implementation manner of the OMS elastic networking device on the basis of the foregoing embodiment of the apparatus. As shown in fig. 8, an OMS elastic networking apparatus provided in an embodiment of the present invention may include: the optical receiver comprises a controller, four optical multiplexing units, m optical transmitters and m optical receivers, wherein the four optical multiplexing units are respectively: an optical multiplexer 1, an optical multiplexer 2, an optical demultiplexer 1 and an optical demultiplexer 2, wherein m is an integer greater than or equal to 1.

In an embodiment of the present invention, the controller identifies OMS types of different types of OMS as OMS-CDM and OMS-WDM, respectively, as in the third embodiment described above. The controller may also directly identify different types of OMSs using OMS priorities, such as OMS using OCDM technology as OMS-1 and OMS using WDM technology as OMS-2, where OMS-1 and OMS-2 are OMS priorities and OMS-1 takes precedence over OMS-2.

For east-oriented transmission, the controller determines OMS-CDM/OMS-1 as the client layer of OMS-WDM/OMS-2, OMS-WDM/OMS-2 as the server layer of OMS-CDM/OMS-1, and the controller determines OMS-CDM/OMS-1 as the uppermost OMS.

Taking TCP for determining OCh as an example, since OMS-CDM/OMS-1 is the uppermost OMS, a TCP point whose G point is OCh is determined between coverage of OCh and OMS-CDM/OMS-1, that is, between "optical transmitter 1" and "optical multiplexer 1", and is set as a TCP point of the first OCh in the embodiment of the present invention.

Further, since the G point is located between the "optical transmitter 1" and the "optical multiplexer 1", the connection supervision information or the maintenance information of the OCh may be inserted or detected by the "optical multiplexer 1" at an input end thereof, or may be inserted or detected by the "optical transmitter 1" at an output end thereof.

Similarly, for west-oriented transmission, it can be determined from the client layer/server layer relationship between OMS's that point Y is also the TCP point of OCh. The OCh processed at point Y may be the same as the OCh processed at point G, i.e. the first OCh (which means that the optical receiver 1 and the optical transmitter 1 process a bidirectional OCh); it may be different from the OCh processed by the point G, for example, the second OCh.

Further, since the Y point is located between the "optical demultiplexer 1" and the "optical receiver 1", connection supervision information or maintenance information of the OCh can be inserted or detected by the "optical receiver 1" at its input.

The meaning of point A, C, Z, X is the same as that of the above device embodiment, and is not repeated here.

The embodiment of the invention provides an OMS elastic networking device, and particularly provides a specific implementation mode of the OMS elastic networking device, wherein the OMS elastic networking device further comprises an optical transmitter and an optical receiver, and the OMS allows two optical multiplexing technologies of OCDM and WDM to be nested for use. According to the OMS elastic networking device provided by the embodiment of the invention, when a fault occurs in the optical network, whether the fault point belongs to the OCh can be determined, the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.

Optionally, the control unit 11 is specifically configured to:

the functional reference points of the OTS are determined within the coverage of the lower OMS based on the client layer/server layer relationships between the OMSs. Wherein, the lower OMS is the server layer of the adjacent upper OMS.

Specifically, the function reference point of the OTS is located within the coverage of the underlying OMS. At this time, the functional reference point of the OTS is limited within the coverage of its corresponding OMS (including different OMS of the same layer and OMS of different layer), and the coverage of the OTS cannot span the coverage of different OMS.

Optionally, the control unit 11 is specifically configured to:

determining a functional reference point of the OTS based on the client layer/server layer relationship within the coverage of the upper OMS and outside the coverage of the immediately lower OMS of the upper OMS. Wherein, the upper layer OMS is a client layer of the next lower layer OMS.

Specifically, the function reference point of the OTS is located between the coverage of the upper OMS and the lower OMS. At this time, the function reference point of the OTS is limited within the coverage of its corresponding OMS, the coverage of the OTS cannot span the coverage of different OMS (including different OMS of the same layer and OMS of different layer), and the coverage of the OTS in the coverage of the OMS of the upper layer needs to be outside the coverage of the OMS of the lower layer.

It should be noted that, the OTS indication information is marked by adding the OMS indication information corresponding to the OMS, may be complete OMS indication information or only add a part of the OMS indication information, as long as the OTS indication information can indicate whether the OMS corresponding to the OTS is a server layer or a client layer, and the embodiment of the present invention is not particularly limited to a specific implementation manner.

The OTS indication information is explained in detail below by specific examples.

For example, the OMS indication information includes an OMS priority, the OMS priority of the first OMS is OMS-1, the OMS priority of the second OMS is OMS-2, and OMS-1 has priority over OMS-2, so that OMS-1 is an upper layer, and OMS-2 is a lower layer, so that the OTS corresponding to OMS-1 can be identified as OTS-1, and the OTS corresponding to OMS-2 is identified as OTS-2. Because one OTS can only be in the coverage of the OMS corresponding to the OTS, and the OTS corresponding to the OMS of the upper layer needs to be out of the coverage of the OMS of the lower layer, the coverage of the OTS-1 can only be in the coverage of the OMS-1 and is out of the coverage of the OMS-2, and the coverage of the OTS-2 can only be in the coverage of the OMS-2.

Optionally, the management information used when the OTS is managed according to the information of the function reference point of the OTS is marked by adding OMS indication information of the OMS corresponding to the OTS.

It should be noted that, when adding the OMS indication information of the OMS corresponding to the OTS to the management information used in managing the OTS for marking, the management information may be complete OMS indication information, or only add part of the OMS indication information, as long as the management information of the OTS may indicate that the OMS corresponding to the OTS is a server layer or a client layer, and the embodiment of the present invention is not particularly limited to a specific implementation manner.

The OMS elastic networking device provided by the embodiment of the invention is applied to an OMS elastic networking system, and the OMS elastic networking system comprises at least two optical multiplexing units and at least one optical relay unit. It should be noted that various units in the OMS elastic networking system may be implemented in multiple OMS elastic networking devices, rather than being implemented in one OMS elastic networking device. That is, the OMS elastic networking apparatus in the embodiment of the present invention, as shown in fig. 9, may specifically include any one or more of at least one optical relay unit and at least one optical multiplexing unit, and a control unit.

EXAMPLE seven

Fig. 11 is a schematic structural diagram of an OMS elastic networking device according to a seventh embodiment of the present invention, and the embodiment of the present invention provides another specific implementation manner of the OMS elastic networking device on the basis of the foregoing embodiment of the apparatus. As shown in fig. 11, an OMS elastic networking apparatus provided in an embodiment of the present invention may include: the optical amplifier comprises a controller, four optical multiplexing units, m optical transmitters, m optical receivers, an optical amplifier E and an optical amplifier W, wherein the four optical multiplexing units are respectively: an optical multiplexer 1, an optical multiplexer 2, an optical demultiplexer 1 and an optical demultiplexer 2, wherein m is an integer greater than or equal to 1.

Wherein the optical multiplexer 1, the optical multiplexer 2 and the amplifier E are used for east transmission, and the optical demultiplexer 1, the optical demultiplexer 2 and the amplifier W are used for west transmission.

In an embodiment of the present invention, as in the third embodiment, the controller identifies OMS types of different types of OMS as OMS-CDM and OMS-WDM, respectively, where OMS-CDM corresponds to OCDM and OMS-WDM corresponds to WDM. The controller may also directly identify different types of OMSs using OMS priorities, such as OMS using OCDM technology as OMS-1 and OMS using WDM technology as OMS-2, where OMS-1 and OMS-2 are OMS priorities and OMS-1 takes precedence over OMS-2.

For east transmission, the controller determines OMS-CDM/OMS-1 as a client layer or upper layer of OMS-WDM/OMS-2 and OMS-WDM/OMS-2 as a server layer or lower layer of OMS-CDM/OMS-1.

Taking TCP for determining OTS as an example, since there is no optical relay unit between the OMS in the hierarchy nesting vicinity (i.e. there is no optical relay unit between the same-direction, adjacent, same-type function reference points belonging to the OMS in the hierarchy nesting vicinity, respectively, in the embodiment of the present invention, specifically, corresponding to fig. 11, it can also be intuitively understood that there is no optical amplifier between the optical multiplexer 1 corresponding to OMS-CDM/OMS-1 and the optical multiplexer 2 corresponding to OMS-WDM/OMS-2, and likewise, there is no optical amplifier between the optical demultiplexer 2 and the optical demultiplexer 1), it is not necessary to set the corresponding OTS to OMS-CDM/OMS-1, i.e. there is no OTS-1 in the embodiment of the present invention. Therefore, based on the client layer/server layer relationship between OMSs, point I is determined to be the functional reference point of the OTS within the coverage of the lower layer OMS (OMS-WDM/OMS-2 in this embodiment). Assuming that the OTS corresponding to OMS-WDM/OMS-2 is marked as OTS-2, point I is the TCP function reference point of OTS-2.

Similarly, for western transmissions, OMS-CDM/OMS-1 is the upper OMS, OMS-WDM/OMS-2 is the lower OMS, and there is no optical amplification between the upper and lower OMS. And according to the client layer/server layer relation between OMSs, determining the W point as a TCP function reference point of the OTS-2 in the coverage range of a lower-layer OMS (OMS-WDM/OMS-2).

The meaning of point A, C, Z, X, G, Y is the same as that of the above embodiments, and is not repeated here.

The embodiment of the invention provides an OMS elastic networking device, and particularly provides a specific implementation mode of the OMS elastic networking device, wherein the OMS elastic networking device further comprises an optical amplifier, an optical relay unit is not arranged between the OMS which are nested and adjacent in layers, and the OMS allows two optical multiplexing technologies of OCDM and WDM to be nested and used. According to the OMS elastic networking device provided by the embodiment of the invention, when a fault occurs in the optical network, whether the fault point belongs to the OTS can be determined, the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.

Example eight

Fig. 12 is a schematic structural diagram of an OMS elastic networking device according to an eighth embodiment of the present invention, which provides another specific implementation manner of the OMS elastic networking device based on the foregoing embodiment of the apparatus according to the embodiment of the present invention. As shown in fig. 12, an OMS elastic networking apparatus provided in an embodiment of the present invention may include: the optical amplifier comprises a controller, four optical multiplexing units, m optical transmitters, m optical receivers, an optical amplifier E and an optical amplifier W, wherein the four optical multiplexing units are respectively: an optical multiplexer 1, an optical multiplexer 2, an optical demultiplexer 1 and an optical demultiplexer 2, wherein m is an integer greater than or equal to 1.

The optical multiplexer 1, the optical multiplexer 2 and the optical amplifier E are used for east transmission, and the optical demultiplexer 1, the demultiplexer 2 and the optical amplifier W are used for west transmission.

Taking TCP for determining the OTS as an example, since there is an optical relay unit between the OMS nested in a hierarchy and adjacent to each other (i.e. there is an optical relay unit between the same-direction, adjacent, same-type function reference points belonging to the OMS nested in a hierarchy and adjacent to each other respectively, in the embodiment of the present invention, corresponding to fig. 12, it can also be intuitively understood that there is an optical amplifier E between the optical multiplexer 1 corresponding to OMS-CDM/OMS-1 and the optical multiplexer 2 corresponding to OMS-WDM/OMS-2, and there is an optical amplifier W between the optical demultiplexer 2 and the optical demultiplexer 1), according to the client layer/server layer relationship between the OMS, there is determined an I point as the function reference point of the OTS between the coverage range of the OMS in an upper layer and the OMS in a lower layer. Assuming that the OTS corresponding to OMS-CDM/OMS-1 is marked OTS-1, point I is the TCP function reference point of OTS-1.

Further, since the point I is located between the "optical amplifier E" and the "optical multiplexer 2", the "optical multiplexer 2" may insert or detect the connection supervision information or the maintenance information of the OTS-1 at its input end, i.e. if the OTS is set between the OMS layers nested adjacently in a hierarchy, the OTS may be monitored at the entrance of the OMS as a server layer. Connection supervision information or maintenance information of the OTS-1 can also be inserted or detected at its output by the "optical amplifier E".

Similarly, for west-oriented transmission, OMS-CDM/OMS-1 is an upper OMS, OMS-WDM/OMS-2 is a lower OMS, and optical relay units are arranged between the OMSs in the hierarchy and the adjacent OMSs (namely between the upper OMS and the lower OMS). And according to the relation of the client layer/the server layer, determining a W point as a TCP function reference point of the OTS-1 between the coverage ranges of the upper layer OMS and the lower layer OMS.

Further, since the point W is located between the "optical demultiplexer 2" and the "optical amplifier W", the "optical demultiplexer 2" may also insert or detect the connection supervision information or maintenance information of the OTS-1 at its output, that is, if the OTS is set between the OMS layers nested adjacently in the hierarchy, the OTS may be monitored at the exit of the OMS as the server layer. Connection supervision information or maintenance information of the OTS-1 may also be inserted or detected at its input by the "optical amplifier W".

The embodiment of the invention provides an OMS elastic networking device, and particularly provides a specific implementation mode of the OMS elastic networking device, wherein the OMS elastic networking device further comprises an optical amplifier, a relay unit is arranged between two adjacent OMSs in a nested manner, and the OMS allows two optical multiplexing technologies of OCDM and WDM to be nested for use. According to the OMS elastic networking device provided by the embodiment of the invention, when a fault occurs in the optical network, whether the fault point belongs to the OTS can be determined, the positioning accuracy of the fault point is improved, the network maintenance efficiency is improved, and the reliable transmission of services is ensured.
