Description

OTU的配置方法及装置 The configuration method and apparatus OTU

技术领域 FIELD

[0001] 本发明涉及光传输网络规划领域,尤其涉及一种光转发单元(OTU,Optical TransformUnit)的配置方法及装置。 [0001] The present invention relates to an optical transmission network planning, and in particular relates to a configuration method and an apparatus for the optical transponder unit (OTU, Optical TransformUnit) a.

背景技术 Background technique

[0002] 当前光纤通信技术已经比较成熟,在大规模通信网络中,对于光纤中光信号的能量的衰减,信号质量的下降,需要对光信号进行放大,再生和定时。 [0002] The current optical fiber communication technology is relatively mature, large-scale communication network, the energy for drop optical fiber attenuation of the optical signal, the signal quality, it is necessary to amplify the optical signal, and a timing reproduction. 同时,在密集波分复用(DWDM,DenseWavelengthDivisionMultiplexing)全光网中,源-宿节点间通过建立光通道实现光域内的数据交换,一条光通道可以跨越多条链路以及多个节点,如果节点不具备波长变换能力,则光通道必须满足波长连续性限制。 Meanwhile, in the dense wavelength division multiplexing (DWDM, DenseWavelengthDivisionMultiplexing) all-optical network, the source - sink nodes for data exchange between the optical domain by establishing an optical channel, an optical channel may span a plurality of links and a plurality of nodes, if the node does not have wavelength conversion capability, the optical path must satisfy the wavelength continuity constraint. 如果节点具有波长变换能力,则在一条光通道的不同链路上可以使用不同的波长。 If a node with wavelength conversion capability, different links in an optical channel may use different wavelengths. 波长变换可以提高网络性能,但是由于波长变换器的成本居高不下,目前还不能考虑在所有的网络节点上都配置波长变换器。 Wavelength conversion can improve network performance, but due to the high cost of a wavelength converter, are not currently considered wavelength converter disposed on all network nodes. 因此,当前对于波长变换器应用的研宄主要是考虑在部分网络节点上配置波长变换器,这种部分节点具有波长变换能力的DWDM全光网也被称为稀疏波长变换网络。 Thus, the current applied to the wavelength converter study based mainly on account of a wavelength converter disposed on a portion of a network node, such a node portion having wavelength conversion capability DWDM optical networks, also known as sparse wavelength conversion network.

[0003] 从波长变换器的变换范围来看,波长变换器主要可分为部分(有限)波长变换器和完全波长变换器两种类型。 [0003] From the point of view of the conversion range of the wavelength converter, the wavelength converter can be divided into two kinds of portions (limited) wavelength converter type and full wavelength converters. 其中,完全波长变换器可以将输入信号变换到任意波长上进行输出,而部分(有限)波长变换器则有一定的波长变换限制,例如将输入波长上的信号交换到临近的输出波长上去。 Wherein the wavelength converter may be completely converted to an input signal and outputs any wavelength, and some (limited) wavelength converters converting the wavelength of a certain limit, for example, the wavelength of the input signal switching output wavelength up to near.

[0004] 随着DWDM技术的日益成熟,DWDM技术正逐步从干线网渗透到城域网的建设中来。 [0004] With the increasing maturity DWDM technology, DWDM technology is gradually infiltrated from the backbone network to build metropolitan area in the past. 由于OTU和光放大器在DWDM应用投资占据较大比例,因此有必要对OTU在DWDM技术中的使用情况进行研宄。 Since the optical amplifier OTU and occupy a large proportion of the investment in DWDM applications, it is essential to use in the OTU DWDM technology is a Subsidiary. 在开放式DWDM系统中,OTU主要有两大功能:一是波长转换功能,即在发送端将来自同步数字体系(SDH,SynchronousDigitalHierarchy)的G. 957光接口转换为符合G. 692标准的光接口;二是3R功能,即定时、再生和整形功能。 In an open DWDM system, the OTU has two main functions: G. 957 interface converter one optical wavelength conversion function, i.e., at the transmission end from the Synchronous Digital Hierarchy (SDH, SynchronousDigitalHierarchy) is in line with G. 692 standard optical interface ; Second 3R function, i.e. the timing, regeneration and shaping functions. 在目前的DWDM系统中,在发送端采用OTU是为了将非标准的波长转换为标准波长;在接收端OTU的作用是将传输来的光信号恢复为信号的原始波长,以及在OTU中对传送过来的光信号进行相应的处理,比如色散补偿等,以利于减小接收的误码;而在中继器中使用OTU是为了将信号进行再生,以降低光信号时延抖动,同时对某些再生段字节进行监视。 In the current DWDM system, the transmitting side is employed in order OTU to wavelength conversion to nonstandard standard wavelength; OTU at the receiving end to restore the role of an optical signal transmitted from the wavelength of the original signal and of the transmitted OTU over the corresponding optical signal processing, such as dispersion compensation, in order to facilitate reducing the received error; OTU used in the repeater signal to be reproduced, the optical signal to reduce jitter, while some regeneration section monitoring bytes. 多个OTU的捆绑使用也可以实现多波长输入输出效果,进而近似实现完全波长变换器的功能,同时器件的成本可以节省很多。 OTU plurality of bundled multi-wavelength may be input output, and thus approximately a wavelength converter to achieve full functionality, while the cost of the device can save a lot.

[0005] 目前,传统的波长变换器配置技术主要集中在完全波长变换器,并没有对实际通信网络中普遍使用的OTU进行过多的研宄,实际施工中,OTU采用粗放式配置,较少被复用, 不仅OTU的配置会存在不合理的情况,而且会造成OTU的使用浪费,导致OTU的使用成本高和网络的生存性差。 [0005] Currently, conventional wavelength converter disposed in the art is fully focused on the wavelength converter, and no undue OTU study based on the actual communication network commonly used in actual construction, the extensive use of OTU configuration, less multiplexed, OTU configuration there will be not only unreasonable, but also will result in the use of waste OTU, resulting in high cost OTU survivability of the network and poor.

[0057] 实际应用中,具体的路由计算算法可自由选定。 [0057] In practical applications, the specific route calculation algorithm can be freely selected. 如果每条业务有多条恢复路由,可以将一个业务的所有恢复路由作为一个集合;为各业务计算路由后,还配置各业务工作路由的SRLG。 If a plurality of restoration routes each service, a restoration route all traffic can be used as a set; after each service route calculation, the working is further configured to route traffic SRLG.

[0058] 步骤302 :基于波长一致性,分别为各业务的工作路由配置OTU; [0058] Step 302: Based on the consistency of wavelengths, are arranged to work OTU each service route;

[0059] 具体地,如图4所示,对于每一个业务的工作路由,基于波长一致性为其配置OTU 的实现过程可以包括如下子步骤: [0059] Specifically, as shown, a working route for each service, based on the wavelength consistency to realize its configuration procedure may comprise the following sub-OTU Step 4:

[0060] 步骤3021 :检测当前业务的工作路由是否因波长一致性而需要配置0TU,如果是, 则继续步骤3022 ;否则,结束当前流程; [0060] Step 3021: detecting whether the current service work due to wavelength routing consistency needs to be configured 0TU, and if so, proceed to Step 3022; otherwise, the current process ends;

[0061] 实际应用中,对于任何业务的任意一个路由,如果无法满足波长一致性,而需要调整波长,则因波长一致性而需要为该路由配置OTU;如果满足波长一致性,则不需要因波长一致性而为该路由配置0TU。 [0061] In practice, for any route of any business, if not meet the wavelength consistency, while the need to adjust the wavelength, due to the need to configure the wavelength conformance of the route OTU; satisfied if the wavelength consistency, because there is no need consistency configured 0TU wavelength of the route.

[0062] 步骤3022 :在当前业务的工作路由上,依次在需要波长转换的节点上配置0TU,并标记所配置的OTU为工作路由所属,结束当前流程。 [0062] Step 3022: In the current work on routing traffic, the nodes are sequentially arranged on the wavelength conversion required 0TU, OTU mark and configured to work route belongs, the current process ends.

[0063] 这里,不同业务间的工作路由不复用0TU,独享为其配置的0TU。 [0063] Here, the work of routing between different business no longer use 0TU, exclusive 0TU its configuration.

[0064] 步骤303 :基于物理损伤因素,分别为各业务的工作路由配置OTU; [0064] Step 303: Based on physical damage factors, the working route of each service are configured OTU;

[0066] 步骤3031 :检测当前业务的工作路由是否因物理损伤因素而需要配置0TU,如果是,则继续步骤3022 ;否则,结束当前流程; [0066] Step 3031: detecting whether the current service routing work due to physical damage factors need to configure 0TU, and if so, proceed to Step 3022; otherwise, the current process ends;

[0067] 具体地,计算当前业务的物理损伤参数,并检测该物理损伤参数是否满足预设的物理损伤条件,如果满足条件,则不需要因物理损伤因素而为当前业务的工作路由配置0TU,如果不满足条件,则需要因物理损伤因素而为当前业务的工作路由配置0TU。 [0067] Specifically, physical damage to calculate a current parameter of the service, and detects a predetermined condition is physical damage to the physical damage parameter is met, if the condition is not required because of physical damage factors 0TU configured to route traffic in the current work, If the condition is not satisfied, it is necessary due to physical damage factors for the current business work routing configuration 0TU. 例如,所述物理损伤参数可以是误码率,预设的物理损伤条件可以是误码率达到10%,具体的参数的设定视使用情况来具体决定,不仅限于误码率。 For example, the physical parameter may be a bit error rate of injury, physical damage to the preset condition may be a bit error rate of 10%, depending on the particular use to set specific parameters of the decision, the error rate is not limited.

[0068] 步骤3032 :在当前业务的工作路由上,基于仲裁规则在满足物理损伤条件的节点上配置0TU,并标记所配置的OTU为工作路由所属,结束当前流程。 [0068] Step 3032: In the current work on the traffic route, based on arbitration rules configured on node satisfies the conditions of physical damage 0TU, OTU mark and configured to work route belongs, the current process ends.

[0069] 具体地,在当前业务的工作路由上出现多个节点上配置OTU均能够满足物理损伤条件时,按照仲裁规则在满足物理损伤条件的节点中选择一个节点配置0TU。 [0069] In particular, when a plurality of nodes are arranged OTU physical damage to meet the conditions according to arbitration rules to select a node in the node configuration 0TU condition satisfying physical damage occurred on the current routing working traffic.

[0070] 这里,对每条业务的工作路由,分别按波长一致性与物理损伤因素进行处理,目的是便于更清晰的处理。 [0070] Here, the work of each service route, and the wavelength respectively with physical trauma consistency factors treatment, the purpose is to facilitate a clearer process.

[0071] 步骤304 :基于波长一致性,分别为各业务的各恢复路由配置OTU; [0071] Step 304: Based on the consistency of wavelengths, respectively, each arranged to restore the OTU each service route;

[0072] 这里,对一条业务的某一条恢复路由进行波长一致性分析,按需求配置0TU。 [0072] Here, a one of a business recovery routing wavelength consistency analysis, demand configuration 0TU. 如果需要配置OTU的节点上已经配置有0TU,则首先检测已配置的OTU是用于工作路由还是用于恢复路由(即是工作路由所属还是恢复路由所属),如果已配置的OTU是标记为恢复路由所属的,则进一步检测该OTU所承载的全部恢复路由所属业务的工作路由与当前业务的工作路由是否属于同一SRLG,如果不是,则将所述OTU复用到当前业务的当前恢复路由上;否贝1J,在需要配置OTU的节点上为当前业务的当前恢复路由新配置一个0TU。 If the node needs to configure the OTU has been arranged 0TU, the first detected OTU is configured to work for the restoration route or routes (i.e., routing work is relevant to the restoration route belongs), if the flag is OTU configured to restore route belongs, the restoration route is further detect all relevant traffic routes the working OTU carried by the current work belong to the same traffic route the SRLG, if not, then the OTU multiplexed current service routing current recovery; No shellfish 1J, on the nodes need to configure a 0TU OTU new configuration for the current business of the current restoration route.

[0073] 具体地,如图6所示,对于每一个业务的每条恢复路由,基于波长一致性为其配置OTU的实现过程可以包括如下子步骤: [0073] Specifically, as shown in FIG. 6, for each service in each restoration route, based on its consistency to achieve wavelength OTU process configurations may include the following sub-steps:

[0074] 步骤3041 :检测当前业务的当前恢复路由是否因波长一致性而需要配置01^,如果是,则继续步骤3042 ;否则,结束当前流程。 [0074] Step 3041: detecting the current business of the current recovery route is due to the wavelength of consistency needs to be configured 01 ^, and if so, proceed to Step 3042; otherwise, the current process ends.

[0075] 这里,检测过程与步骤3021相似,不再赘述。 [0075] Here, the detection process similar to step 3021, omitted.

[0076] 步骤3042 :在当前业务的当前恢复路由上,检测在需要波长转换的节点上是否已配置有标记为恢复路由所属的0TU,如果是,则继续步骤3043 ;否则,继续步骤3045 ; [0076] Step 3042: In the current restoration routing, the node needs to detect whether the wavelength converter is configured with the marked recovery 0TU route belongs, if yes, step 3043 continues the current service; otherwise, proceeds to step 3045;

[0077] 步骤3043 :所述标记为恢复路由所属的OTU所承载的全部恢复路由所属业务的工作路由与当前业务的工作路由是否属于同一SRLG,如果是,则继续步骤3045 ;否则,继续步骤3044 ; [0077] Step 3043: the label belongs to restore all restoration route traffic routing work OTU route belongs to the current carried by the work belong to the same traffic route the SRLG, if so, proceeds to step 3045; otherwise, proceed to Step 3044 ;

[0078] 步骤3044 :在所述需要波长转换的节点上,复用所述标记为恢复路由所属的OTU 承载当前业务的当前恢复路由,结束当前流程。 [0078] Step 3044: a node in the wavelength conversion required, the labeled complex restoration route belongs OTU current traffic load current restoration route, with the current process ends.

[0080] 步骤305 :基于物理损伤因素,分别为各业务的各恢复路由配置OTU; [0080] Step 305: Based on physical damage factors, respectively, each arranged to restore the OTU each service route;

[0081] 这里,对一条业务的某一条恢复路由进行物理损伤因素分析,按需求配置0TU。 [0081] Here, a one pair of a business recovery routing physical injury factor analysis, demand configuration 0TU. 如果当前业务的当前恢复路由在某一节点因物理损伤因素需配置0TU,而该节点上已有用于恢复路由的0TU,则检测该OTU所承载的全部恢复路由所属业务的工作路由与当前业务的工作路由是否属于同一SRLG,若不是,便复用该OTU到当前业务的当前恢复路由上;否则, 在需要配置OTU的节点上为当前业务的当前恢复路由新配置一个0TU。 If the current service routing in current recovery because a node needs to be configured physically damaging factors 0TU, and the existing node for the restoration route of 0TU, the restoration route is detected all relevant traffic routes the working OTU carried by the current service job routing belong to the same SRLG, if not, then reuse the OTU to the current business of the current recovery on the route; otherwise, the node has to set a new configuration of the OTU 0TU for the current business of the current restoration route.

[0082] 如果当前业务的当前恢复路由上,有多个节点适合因物理损伤因素而配置OTU或因物理损伤因素而需配置多个0TU,则按照仲裁规则在满足物理损伤条件的节点中选择节点配置OTU。 Node [0082] If the current service routing current recovery, for a plurality of nodes are arranged by physical injury factors or by physical damage OTU factors required plurality 0TU, according to the arbitration rules to meet the physical damage condition selected node Configuring OTU.

[0083] 具体地,如图7所示,对于每一个业务的每条恢复路由,基于波长一致性为其配置OTU的实现过程可以包括如下子步骤: [0083] Specifically, as shown in FIG. 7, for each of a restoration route for each service, based on the wavelength consistency to realize its OTU process configurations may include the following sub-steps:

[0084] 步骤3051 :检测当前业务的当前恢复路由是否因物理损伤因素而需要配置0TU, 如果是,则继续步骤3052 ;否则,结束当前流程。 [0084] Step 3051: detecting the current business of the current recovery route is due to physical damage factors need to configure 0TU, and if so, proceed to Step 3052; otherwise, the current process ends.

[0085] 这里,具体的检测过程与步骤3031相似,不再赘述。 [0085] Here, the specific detection process similar to step 3031, omitted.

[0086] 步骤3052 :在当前业务的当前恢复路由上,在基于仲裁规则在满足物理损伤条件的节点上配置OTU之前,检测在该节点上是否已配置有标记为恢复路由所属的0TU,如果是,则继续步骤3053 ;否则,继续步骤3055 ; [0086] Step 3052: at the current recovery current traffic route, before configuring OTU at the node satisfies physical damage condition based on arbitration rules, detection on whether the node is configured with the marked recovery route belongs 0TU, if , it proceeds to step 3053; otherwise, continue to step 3055;

[0087] 步骤3053 :所述标记为恢复路由所属的OTU所承载的全部恢复路由所属业务的工作路由与当前业务的工作路由是否属于同一SRLG,如果是,则继续步骤3055 ;否则,继续步骤3054 ; [0087] Step 3053: the label belongs to restore all restoration route traffic routing work OTU route belongs to the current carried by the work belong to the same traffic route the SRLG, if so, proceeds to step 3055; otherwise, proceed to Step 3054 ;

[0088] 步骤3054:在所述节点上复用所述标记为恢复路由所属的OTU承载当前业务的当前恢复路由,结束当前流程。 [0088] Step 3054: the node in the route belongs OTU marked recovery current bearer service recovery current route, the current process ends multiplexed.

[0090] 如图8所示,在上述流程中,按照仲裁规则在满足物理损伤条件的节点中选择需要配置OTU的节点,具体实现过程,包括如下步骤: [0090] As shown in the above flow, according to the arbitration rules node satisfies the conditions selected physical damage 8 OTU node needs to be configured, the specific implementation process, comprising the steps of:

[0091] 步骤801 :将当前业务的当前路由(恢复路由或工作路由)上源宿节点之间第一个不满足物理损伤条件的节点确定为配置OTU的节点; [0091] Step 801: The first node does not satisfy the physical damage on the current condition of the current route between the service (or working route restoration route) source and sink nodes is determined as a node configuration OTU;

[0092] 步骤802 :在上一步所确定配置OTU的节点上配置0TU,并检测当前业务的物理损伤参数是否满足需求(即是否满足预设的物理损伤条件),如果是,则继续步骤803,否则, 继续步骤805 ; [0092] Step 802: the configuration determined in the previous step 0TU node configuration of OTU, and detects the current service parameter meets the needs of physical damage (i.e., the preset condition is satisfied physical damage), and if yes, proceeds to step 803, otherwise, proceed to step 805;

[0093] 步骤803 :撤掉已配置的0TU,轮询当前路由上源宿节点之间的各节点(不包括源宿节点),确定配置OTU的备选节点:分别在各节点上配置0TU,并检测当前业务的物理损伤参数是否满足物理损伤条件,是则将该节点标记为配置OTU的备选节点,否则不标记该节点为配置OTU的备选节点; [0093] Step 803: 0TU removed configured, polling each node between the current source and sink nodes on the route (not including the source and sink nodes), configured to determine candidate nodes OTU: 0TU are disposed on each node, physical damage parameters and detects the current traffic condition is satisfied if physical damage, the node is marked as the alternative configuration of OTU node, the node is not marked or alternatively an OTU node configuration;

[0094] 步骤804 :计算得到各备选节点的权值,选择权值最大的备选节点作为最终需要配置OTU的节点,至此,当前流程结束。 [0094] Step 804: calculate weights each candidate node, the maximum value of the option node as the final candidate node needs to be configured OTU, thus, the current flow is ended.

[0095] 这里,节点权值的计算公式如下式(1): [0095] Here, the node weights calculated by the following formula formula (1):

Figure CN102638303BD00101

[0097] 其中,w (V)表示节点V的权值,函数deg(V)表示节点V的度数,k表示源宿节点对间预先计算的路由个数,X1(^v)表示路由p与节点V之间的关系,满足如下式: [0097] wherein, W (V) is the weight of the nodes V, the function deg (V) V represents a degree nodes, k is the number of routes between source and sink nodes of the pre-calculated, X1 (^ v) and p represents a route the relationship between the nodes V, satisfies the following formula:

[0098] [0098]

Figure CN102638303BD00102

[0099] 在实施过程中,分别计算得到各备选节点的权值之后,选择权值最大的节点作为需要配置OTU的节点。 After [0099] In the process embodiment, weights are calculated for each alternative node, the maximum value of the node as the node has to set options of OTU.

[0100] 步骤805 :在当前业务的当前路由上,将已配置OTU的节点与当前路由上宿节点之间的第一个不满足物理损伤条件的节点,也确定为配置OTU的节点; [0100] Step 805: the current on the current traffic routing, the configured node and the node currently OTU first condition does not satisfy the physical damage on the route between the destination node, the node also determines the configuration of the OTU;

[0101] 步骤806 :在上一步所确定配置OTU的节点上配置0TU,并检测当前业务的物理损伤参数是否满足物理损伤条件,如果是,则继续步骤807,否则,返回步骤805 ; [0101] Step 806: the configuration determined in the previous step 0TU node configuration of OTU, and detects the current service parameter is physical damage to physical damage condition is satisfied, if yes, proceed to Step 807, otherwise, returns to step 805;

[0102] 步骤807 :撤掉上一步所配置的0TU,轮询当前已配置OTU的节点与宿节点之间的各节点(不包括所述已配置有OTU的节点和宿节点),确定配置OTU的备选节点:分别在各节点上配置0TU,并检测当前业务的物理损伤参数是否满足物理损伤条件,是则将该节点标记为配置OTU的备选节点,否则不标记该节点为配置OTU的备选节点; [0102] Step 807: the step 0TU removed configured, polling each node configured between the node and the sink node OTU current (excluding the OTU configured with nodes and sink node), determine the configuration OTU alternative node: each node are arranged in 0TU, and detects the current physical damage if physical damage parameter of the service condition is satisfied, then the node is labeled as node configuration of OTU Alternatively, labeled or not the node configuration of OTU Alternatively nodes;

[0103] 步骤808 :计算得到各备选节点的权值,将权值最大的备选节点、以及当前已配置OTU的节点均作为最终需要配置OTU的节点,并将当前已配置的OTU撤掉,至此,当前流程结束。 [0103] Step 808: calculate weights each candidate node, the maximum weight of the alternative node, and the current node configured as a node OTU are ultimately required configuration of the OTU, and the currently configured OTU removed , so far, the current process ends.

[0104] 例如,对于图9所示的路由,需要经过S-1-2-3-4-5-6-7-D等节点,检测在节点5 处已不满足物理损伤条件,从而导致在宿节点无法接收到满足物理损伤条件的信号。 [0104] For example, the route shown in FIG. 9, need to go through S-1-2-3-4-5-6-7-D peer node detects physical damage conditions have been satisfied at the node 5, resulting in a the sink node can not receive the signal condition satisfies physical damage. 此时, 则从节点S开始在尽可能远的节点(即从满足物理损伤条件下信号传递的最远距离处节点之后的第一个物理损伤参数不满足需求的节点,即节点5)预先配置OTU,配置后如果可以在宿节点接受到满足物理损伤条件的信号(即预设的物理损伤条件),,那么表明此路由最多需要一个OTU就可以完成对物理损伤的补偿。 In this case, node S starts from the node as far as possible (i.e., does not satisfy the needs from the first node after a physical distance of the node to meet the most signaling conditions in physical damage damage parameter, i.e., node 5) preconfigured OTU, the configuration signals (i.e., physical damage to the preset condition) If the destination node receives physical damage satisfies condition ,, indicates that this route requires a OTU can be completed up to compensate for physical damage.

[0105] 如果只需要配置一个OTU即可,那么在源节点S与宿节点D之间的任意一个节点(即节点1、节点2、节点3、节点4、节点5中的任意一个节点)配置OTU都可能使得当前业务的物理损伤参数满足需求。 [0105] If only needs one OTU can, then any node between the source node S and destination node D (i.e., node 1, node 2, node 3, node 4, any one of the nodes 5) arranged OTU are likely to make the current physical damage parameter of the service to meet demand. 此时,撤掉节点5上已配置的0TU,轮询节点1、节点2、节点3、节点4、节点5中各节点:即检测在节点上配置OTU后所述业务的物理损伤参数是否满足需求,如果满足,则将该节点标记为配置OTU的备选节点,在各备选节点中选择权值最大的节点作为最终需要配置OTU的节点。 At this time, removed 0TU configured on the node 5, the polling node 1, node 2, node 3, node 4, node 5, each node: i.e., after detecting the node configuration OTU physical damage on a parameter of the service is satisfied demand, if so, then the node labeled as node configuration OTU Alternatively, the selected node with the largest weight as the final node needs to be configured in each OTU alternate node.

[0106] 如果链路检测在节点3处已不满足物理损伤条件,在节点3配置OTU后,目的节点仍然无法得到符合物理损伤条件的信号,,则可能需要两个或两个以上的0TU,则将节点3 作为第一个需要配置OTU的一个节点,并在节点3上配置OTU;然后,在节点3与节点D之间的第一个不满足物理损伤条件的节点(节点6),检测配置OTU后当前业务的物理损伤参数是否满足需求;如果满足,此时,撤掉节点6上已配置的0TU,轮询节点4、节点5、节点6中各节点:即检测在节点上配置OTU后所述业务的物理损伤参数是否满足需求,如果满足,则将该节点标记为配置OTU的备选节点,在各备选节点中选择权值最大的节点作为最终需要配置OTU的节点。 [0106] If a link is detected at node 3 has not satisfied the conditions of physical damage, 3 is disposed in the OTU succeeding node, a destination node still can not meet the physical damage resulting signal may be required ,, condition two or more of 0TU, node 3 will be configured as a first node of OTU, and node configuration OTU 3; then, at the first node does not satisfy the conditions of physical damage between 3 and node D (node ​​6) detects after the current configuration OTU physical damage parameter meets the needs of the business; if so, at this time, each node 6 6 configured removed node 0TU, polling node 4, node 5, node: that is detected at the node disposed OTU physical damage parameter meets the needs of the service, if so, then the node is marked as alternative configuration OTU nodes, the largest node selected as the node weights in the final required configuration OTU each candidate node. 如果在节点6配置OTU后,目的节点仍然无法得到满足物理损伤因素的信号,然后,在节点6与节点D之间的第一个不满足物理损伤条件的节点(节点7),检测配置OTU后当前业务的物理损伤参数是否满足需求,由于节点6与节点D之间仅有一个节点7,因此,节点7处配置OTU后当前业务的物理损伤参数一定是满足需求的,不需要轮询,直接将节点7也作为最终需要配置OTU的节点。 If the node 6 is disposed in the OTU, the destination node still can not be satisfied from physical damage factor signals, and then, (node ​​7), detecting a first node disposed in the OTU physical damage does not satisfy a condition between the node D and 6 current physical damage parameter meets the needs of the business, since the node D and the node 6 between a node 7 only, therefore, the current node 7 arranged at OTU physical damage parameter of the service needs must be satisfied, no polling, direct the node as the node 7 may eventually need to configure an OTU.
