本申请基于申请号为202010534174.1、申请日为2020年06月12日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域，具体而言，涉及但不限于资源部署方法、设备、管控系统及计算机存储介质。
背景技术
随着互联网技术的快速发展以及5G时代的到来，网络流量呈现快速增长的趋势。而光传输网络(OTN)作为主干网的重要组成部分，单一光路传输速率已经达到百Gbit/s甚至Tbit/s。光纤断裂、设备故障等状况将导致网络中承载的相关业务大规模瘫痪，因此提升OTN网络的抗灾能力具有重要意义。网络生存性是指当网络发生某些灾难故障时，其仍然能够承载一定的业务数据的能力，又可以称为网络抗毁性。网络生存性通常以生存率来表示，可定义为当某条线路出现故障时，可以从其他线路上疏通的业务量与该线路所传输的业务量之比。影响网络生存性的主要因素包括：业务集中的节点链路的性能；网络的保护恢复技术与策略；可能存在的危险因素占比等。光层的业务恢复往往能将时间降低到ms级别，因而业务的光层恢复研究具有较强的现实价值。
与光传输网络生存性相关的技术大体上可以分为保护和恢复两大类。保护策略主要指在设置业务的同时为其预留好相对应的保护或备用资源，一旦业务的主传输通道发生故障立即切换到备用资源上进行业务的传输操作。恢复策略主要是指只为业务设置工作路径资源，当其发生故障时动态的规划现网资源以传输业务。保护策略的主路径和备路径在设置时一般保持链路级别或更高级别的分离策略，因而对于某些预料之内的网络故障，例如单一光纤毁坏等，其可以保证业务能100％恢复成功。保护策略业务恢复时间少，但会浪费一定的频谱和带宽资源；恢复策略节省频谱资源，但业务恢复时间较长。所以综上所述，保护的实现机制是预留资源，具有较低的资源利用率，但是恢复时间较短；恢复策略的实现机制是重路由，恢复时间较长。
针对已部署的光网络，为了保证任意一根光纤断裂时，受影响的业务能通过保护或恢复策略迅速恢复业务传输，往往会在光网络规划时预留一部分网络资源，包括频谱资源和光模块资源，但光模块成本较高，部署冗余光模块会大幅提升光网络部署的成本。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本申请实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
实施例一：
为了相关光网络资源规划算法难以高效、可靠的保证光网络承载的业务在单一光纤损坏的恢复效率以及总的恢复成本的问题，本申请实施例提供一种资源部署方法，模拟网络中任意光纤断裂，并提前预部署一些资源，以保证光纤断裂时，业务重路由成功，如图1所示，该资源部署方法包括：
S101：根据请求部署的各业务的业务信息，部署等级业务为非铜级业务恢复路径的所有路径。
在本申请实施例中，光网络规划系统接收请求网络资源的业务，并获取各业务的业务信息和等级业务，其中该等级业务包括铜级业务和非铜级业务，在一个实施方式中，等级业务可以根据业务的重要程度确定，该非铜级业务包括铁级、银级、金级和钻石级，其中等级业务重要程度铁级<铜级<银级<金级<钻石级。
在本申请实施例中，系统接收各业务，并从中读取请求的业务信息，该业务信息包括源宿节点、带宽信息、必经或/和必避约束信息；其中源宿节点为业务的起始节点和终止节点，带宽信息为业务所需带宽大小，必经约束，即要求待计算的路由必须经过网络拓扑中特定的节点或者链路；必避约束，即要求待计算的路由必须不能经过网络拓扑中特定的节点或者链路。如图2所示，业务1的起始节点为节点2和终止节点8，必经节点为节点7。
在本申请实施例中，可根据业务信息的源宿节点、必经或/和必避约束信息确定业务的路由，例如基于单源最短路径算法，根据业务信息对各业务进行路由操作，确定各业务的主路径，可以理解的是，是确定所有等级业务对应的主路径；如图2中的，业务1的起始节点为节点2和终止节点8，必经节点为节点7，则存在路径2-5-7-8，路径2-4-6-7-8，路径2-1-3-6-7-8，则按照最短偏离路径算法，确定业务1的主路径为2-5-7-8。
为了保证任意一根光纤断裂时，受影响的业务能通过保护、恢复策略迅速恢复业务传输，本申请实施例中，对于不同的等级业务，采用不同的业务恢复策略；
针对铁级业务：该等级业务仅需要保证在网络中部署一条可行路径，并且不具备重路由功能，所以当发生断纤时，该业务可以不作处理；即铁级业务只保证主路径资源，且路径损坏无需恢复。
针对铜级业务(1+R)：该等级业务，需要规划一条工作路由，当光纤断裂时，需要保证该业务恢复路径计算成功。恢复路径需要满足和工作路径的链路和共享风险链路组(SRLG)分离，即铜级保证主路径资源，主路径损坏时要进行业务恢复操作。
针对银级业务(1+1)：该等级业务，需要规划一条工作路由和一条保护路由，当光纤断裂时，业务可以自动切换到保护路径上；所以只需要保证银级业务的工作和保护路径分离成功即可，即同时保证主路径和保护路径资源，主和保护均损坏无需恢复。
针对金级业务(1+1+R)：该等级业务，需要规划一条工作路由和一条保护路由，当光纤断裂时，业务可以自动切换到保护路径上；所以只需要保证金级业务的工作和保护路径分离成功即可。预置恢复路由可成功可失败；无预置的恢复路径可以不计算。
针对钻石级业务(永久1+1)：该等级业务需要规划一条工作路由和一条保护路由，当光纤断裂时，业务可以自动切换到保护路径上；所以只需要保证钻石级业务的工作和保护路径分离成功，且时刻保持业务有两条预置资源的路由存在。预置恢复路由可成功可失败； 无预置的恢复路径可以不计算。
根据上述不同的等级业务不同的业务恢复策略，在确定主路径后，针对非铜级业务中的银级业务、金级业务、钻石级业务，还需要根据业务的路由信息计算业务的保护路径资源，并部署到光传输网络中；例如，根据业务的路由信息，为业务分配频谱资源，根据业务的路由信息和频谱信息，在光网络中部署端口；假设图2中的业务1的等级业务为银级业务，该业务1的保护路径为2-4-6-7-8，则根据该路径计算该保护路径的频谱资源和端口资源(如光模块)。
S102：根据各等级业务为铜级业务的主路径之间的关联关系，在为一铜级业务部署恢复路径时，共享与其不相关的铜级业务的恢复路径资源。
需要说明的是，先在光传输网络中部署非铜级恢复路径的所有路径，针对铜级业务，在一次断纤场景下只需要保证铜级业务能够在现有端口资源基础上能够成功恢复业务。根据各铜级业务的主路径之间的关联关系，确定铜级业务的恢复路径的部署方式；其中铜级业务的主路径之间的关联关系包括铜级业务的主路径的重合度，包括完全重合，不完全重合。
由于光传输网络还未部署铜级业务的恢复路径，当两个铜级业务的主路径完全重合时，根据业务信息分别计算与主路径分离的恢复路径资源，并部署到光传输网络中，路径资源包括频谱资源和端口资源。假设确定各铜级业务，依次计算各铜级业务恢复路径，由于光传输网络中不存在铜级业务的恢复路径，先直接部署第一个铜级业务的恢复路径，恢复路径与主路径保证链路分离，并预先为该恢复路径分配频谱资源、部署光模块。部署第二个铜级业务的恢复路径时，当第二个铜级业务的主路径与第一个铜级业务的主路径完全重合，则需计算资源完全独占的恢复路径，即第二个铜级业务恢复路径的资源要和第一个铜级业务的资源保持独立不能共享，并保证第二个铜级业务恢复路径与主路径链路分离。
在本申请实施例中，当存在铜级业务的主路径不完全重合时，部署某个铜级业务恢复路径，共享与其不相关的铜级业务的恢复路径资源；例如若两个铜级业务的主路径部分重合，那么对于重合链路断纤的场景下需保证恢复路径之间资源隔离，不重合链路断纤时可以共享恢复路径资源；如果两个铜级业务主路径完全不重合，则这两个铜级业务的恢复路径可以共享同一路径资源，进而可以使得端口成本进一步减少。承接上例，第三个铜级业务的主路径与第一个铜级业务的主路径没有经过相同的链路，即完全不重合，在单一光纤损坏而导致业务中断的场景下，这两个业务不会同时中断业务，这两个铜级业务不会同时切换至恢复路径，在部署第三个铜级业务的恢复路径时可以共享第一个铜级业务的恢复路径资源。
通过上述共享网络和光模块资源的技术方案，已经在一定程度上减少了光模块的使用，获得较优端口预部署的网络，在此基础上，在本申请实施例提供的资源部署方法可以对网络资源部署进行进一步优化，如图3所示，根据共享策略部署完所有业务之后，进化算法对网络资源做进一步的优化流程包括：
S301、对已部署的业务的部署结果进行扩展得到父代种群。
S302、对父代种群中的部分个体进行变异操作得到子代种群。
S303、根据端口资源的消耗量，从父代种群和子代种群中选取最优个体。
S304、将最优个体对应的部署结果部署到光传输网络中。
在本申请实施例中，将按照步骤S101-S103部署得到的业务的部署结果作为初始解，并进行扩展得到父代种群，例如，通过深拷贝方式将初始解扩展至规定的种群规模n，然后对父代种群n中的部分个体进行变异操作，其中一个个体指的是光传输网络中所有业务的部署方案，则父代种群中有n个个体，选择部分个体进行变异操作得到子代种群，该变异操作包括释放个体内部分的业务对应路径资源，根据当前光传输网络状态重新部署释放后的业务的路径；在一些实施例中，选择部分个体进行变异操作可以是通过随机选择个体，也是可以是对每个个体通过计算产生随机数x，该x为0～1，当该x小于预设变异率，则对该个体进行变异操作；例如假设某个个体对应的随机数为0.2，小于预设变异率30％，则对该个体进行变异操作；类似于为每个个体编号，通过丢骰子的计算方式，确定丢出的个体编号，当该个体编号小于预设变异编号，则对该个体进行变异操作。变异操作中释放个体内部分的业务对应路径资源，在一些实施例中，抽取个体内的部分已部署的业务，当抽取的业务是铜级业务时，释放该铜级业务的恢复路径资源；当抽取的业务是非铜级业务时，释放非铜级业务的主路径；或，主路径和保护路径资源；或，主路径、保护路径和恢复路径资源；即铁级业务，释放主路径的频谱和端口资源，银级、金级、钻石级释放主路径和保护路径的频谱和端口资源，或银级释放主路径和保护路径的频谱和端口资源，金级、钻石级释放主路径、保护路径和恢复路径的频谱和端口资源；释放相应路径资源后，根据当前光传输网络状态重新部署拆除掉的业务相关路径，尽可能多的复用当前网络的剩余端口资源；可以理解为，光传输网络根据时间的推移，其网络资源发生的变化，例如部分业务完成数据传输后自动释放掉资源，进而光传输网络资源比之前的资源多；其中根据当前光传输网络状态重新部署拆除掉的业务相关路径时，仍然按照步骤S101-S103进行部署路径资源，进而通过铜级业务占用其不相关的铜级业务的恢复路径资源复用当前网络的剩余端口资源。
需要说明的是，根据端口资源的消耗量，从父代种群和子代种群中选取最优个体是通过迭代的方式选取最优个体；从父代种群和子代种群的并集中，选取所需端口的消耗量最少的前n个个体作为当前父代种群，对当前父代种群进行变异操作得到当前子代种群；其中，该n可以与初始父代种群(即S301的父代种群)相同，也可以不同；直到种群迭代次数大于最大迭代次数，从最后一次迭代对应的父代种群和子代种群的并集中选取端口资源最少的个体，作为最优个体。例如初始父代种群包括100个个体，变异率为30％，则得到30个子代个体，则从这100+30个个体的端口资源消耗量进行排序，选择前100个个体作为第二代父代种群，然后对第二代父代种群中的部分个体进行变异操作得到第二代子代种群，此时为迭代次数为2，继续从第二代父代种群和第二代子代种群中选择端口资源最少的前100个个体继续进行变异操作，直到种群迭代次数大于预设最大迭代次数，则从最后一个的父代种群和子代种群的并集中选取端口资源最少的个体作为最优个体。在一些实施例中，也可以是当从父代种群和子代种群中能选择出满足实际需求的个体时，则停止种群迭代，将当前父代种群和子代种群中的并集中端口资源最少的个体，作为最优个体。最后将最优个体(即所有业务对应的部署结果均为光传输网络中最优的，复用端口资源最多的)作为断纤规划的最终方案，部署到光传输网络中。
本申请实施例提供的资源部署方法，通过获取请求部署的各业务的业务信息和等级业务，等级业务包括铜级业务和非铜级业务；根据业务信息部署非铜级业务恢复路径的所有 路径；根据各铜级业务的主路径之间的关联关系，在为某个铜级业务部署恢复路径时，共享与其不相关的铜级业务的恢复路径资源，路径资源包括频谱资源和端口资源，能够根据网络资源信息和网络中的业务信息，输出一种端口资源的部署方案，同时输出一种业务的路由和频谱分配方案,并保证在单一光纤损毁场景下业务恢复的成功率和网络总成本。具体的，能够针对不同等级业务的业务采用相应的保护或恢复策略，保证银、金、钻四种业务，存在两条满足SRLG分离的路径，并通过铜级业务占用不相关的铜级业务的恢复路径资源，实现共享频谱和端口资源提升业务恢复成功率，降低网络部署成本；能够在满足单一光纤损毁场景下的约束前提下，使得网络部署的端口模块数量更少，从而降低光网络部署成本。
实施例二：
在一些情况中，商用可重构光分插复用器(ROADM)设备还不具备全光再生技术，因此业务在ROADM设备上只能通过部署光/电/光转换(OEO)端口的方式来实现发送、接收、跳波、聚会和拆分等操作。
发送和接收：如图4中的业务1所示，当该网元为业务1的原宿节点时，由于客户侧均为电信号，因此需要为出站光纤的λ1分配一个OEO端口，从而将业务1由电信号转换成光信号。
跳波操作：如业务2所示。业务2在入站光纤中由波长λ1传输，在经过站点时，先由光信号被转换成电信号，经过电层模块后，再由电信号转换成光信号，并被分配到出站光纤的波长λ2中。因此需要在该网元上为入站光纤的λ1和和出站光纤的λ2各分配一个OEO端口。
业务汇聚和拆分：如业务2和业务3所示。业务3在入站光纤上独占波长λ2，但是经过该站点后，和业务2一起汇聚到了出站光纤的波长λ2中。因此，需要为入站光纤的λ1和λ2各分配一个OEO端口，负责将业务2和业务3转换成电信号。同时，需要为出站光纤的波长λ2分配一个OEO端口，负责将业务2和业务3汇聚后的电信号转换成光信号。
如果业务在经过站点时只经过光交叉矩阵实现转发，则不需要部署OEO端口，如业务0。虽然在ROADM设备上部署OEO端口能够使业务在传输过程中实现跳波、汇聚和拆分等操作，极大程度上提高了WDM网络资源调度的灵活性，但是OEO设备成本较为昂贵。所以运营商在部署业务和OEO端口时，需要均衡业务部署带来的收益和OEO端口部署付出的成本。
针对已部署的光网络，为了保证任意一根光纤断裂时，受影响的业务都能迅速恢复业务传输，往往会在光网络规划时预留一部分网络资源，包括频谱资源和OEO端口资源，为了光网络规划系统需要在保证服务质量的同时，尽可能地减少部署OEO端口数量，本申请 实施例以一个较为具体的例子对资源部署方法进行说明，如图5所示，该资源部署方法包括：
S501：初始化光传输网络的频谱资源、已有业务和已部署的端口信息；
S502：接收批量待规划的业务，并从中读取请求的源宿节点、带宽信息、必经必避约束信息和等级业务；
S503：根据业务信息，将除带宽外其他要求均一致的业务汇聚成单通道最大带宽资源大小的合并业务请求；
S504：依据合并业务带宽，从大到小进行排序操作；
S505：选取还未部署的业务，使用最短路径算法Yen-ksp算法进行路由操作；
根据源宿节点、必经必避约束信息，按照Yen-ksp算法进行路由操作，确定业务的主路径。
S506：根据业务的路由信息，为业务分配频谱资源；
S507：根据业务的路由信息和频谱信息，在光网络中确定OEO端口；
S508：根据业务的等级业务计算相关业务的路径资源。
在本申请实施例中，铁级只保证主路径资源，且路径损坏无需恢复；铜级保证主路径资源，主路径损坏时要进行业务恢复操作；银级同时保证主路径和保护路径资源，主路径和保护路径均损坏无需恢复；金级同时保证主路径和保护路径资源，路径均损坏时需进行业务恢复操作；钻石级时刻保持业务有两条预置资源的路由存在。若还有业务未部署则跳转至S505。
S509：对于所有请求，在光传输网络上部署非铜级恢复路径的所有路径，并部署中继和功能端口；
S510：根据各铜级业务的主路径之间的关联关系，在为某个铜级业务部署恢复路径时，共享与其不相关的铜级业务的恢复路径资源。
该步骤S510具体如图6所示，包括以下步骤：
S601：假定所有非铜级业务已按其业务要求部署到现网中，只存在4个铜级业务；
S602：部署铜级业务的主路径，如图7所示，业务1的主路径为2-5-7，业务2的主路径为2-5-7，业务3的主路径为5-7-6，业务4的主路径为1-3-6；
S603：采集铜级业务主路径信息，从业务1开始依次计算恢复路径及部署相关光模块；
S604：由于现网中不存在铜级业务的恢复路径，则直接计算业务1的恢复路径(与其主路径保持链路分离)并预分配资源和部署OEO端口；
S605：部署业务2，由于业务2与现网中已存在恢复路径的业务1路径完全重合，则在一次断纤场景下，两个业务会同时受影响。因而，业务2恢复路径的资源要和业务1的 资源保持独立不能共享，并保证业务2恢复路径与主路径链路分离。
S606：部署业务3，业务3与业务1和业务2的主路径在链路(5-7)上重合。当重合链路发生断纤时，三个业务同时受影响，则其恢复路径之间保持资源分离。当不重合链路发生断纤时，业务3可以共享业务1,2的恢复路径资源。这两种情况下的两条恢复路径，彼此之间可以共享资源。
S607：部署业务4，业务4与业务1,2,3主路径均不存在重合链路，则在部署业务4恢复路径的时候可以共享业务1,2,3的恢复路径的相关资源。
本申请实施例提供一种资源部署方法，先根据业务的业务信息确定业务的路径，进而在光传输网络中部署非铜级恢复路径的所有路径，在一次断纤场景下只需要保证铜级业务能够在现有端口资源基础上能够成功恢复业务，通过获取铜级业务主路径之间的关联关系，确定铜级业务主路径的重合度，对于不完全重合的业务，占用其不相关的铜级业务的恢复路径资源，尽可能多的复用当前网络资源，优化光网络部署成本。
实施例三：
本申请实施例在实施例二的基础上，进一步地对网络资源进行优化，如图8所示，包括以下步骤：
S801：获取所求得的业务和端口规划方案，作为初始解；
将实施例二中步骤S510所求得的业务和端口规划方案，作为初始解。
S802：通过深拷贝方式将初始解数量拓展至制定的种群规模n；
S803：通过计算对种群中的个体产生随机数x，若x<变异率p，则对该个体进行相应的变异操作，并更新其状态；反之，则跳过；
S804：释放个体内部分的业务对应路径资源并拆除没有业务关联的端口，根据当前光传输网络状态重新部署释放后的业务的路径。
随机抽取个体内k条规划结果中已部署的业务，若业务为铜级业务，则释放铜级业务的相关恢复路径频谱和端口资源；否则，释放业务主路径；或，主路径和保护路径资源；或，主路径、保护路径和恢复路径相关的频谱和端口资源。重新根据实施例二的步骤部署拆除掉的业务相关路径，尽可能多的复用当前网络的剩余端口资源；
S805：完成对所有个体的变异操作，从子代和父代种群的并集中，以端口的资源消耗为衡量指标，选取所需端口资源最少的前n个个体作为下一代种群；
对下一代种群部分的个体进行变异操作，即重复步骤S803-S805。
S806：判断是否满足迭代终止条件；如是，则进行S807，如否，则进行S806。
当前迭代次数大于最大迭代次数或者当前最优解以满足用户需求，则判定满足迭代终 止条件。
S807：输出端口成本最低的个体作为最终的一次断纤规划方案。
从最后一次迭代对应的父代种群和子代种群的并集中选取端口资源最少的个体作为最终的一次断纤规划方案。
