具体实施方式
为使本领域的技术人员更好地理解本公开的技术方案，下面结合附图对本公开提供的虚拟资源信息的同步方法、编排器、电子设备、计算机可读介质进行详细描述。
在下文中将参考附图更充分地描述示例实施例，但是所述示例实施例可以以不同形式来体现且不应当被解释为限于本文阐述的实施例。反之，提供这些实施例的目的在于使本公开透彻和完整，并将使本领域技术人员充分理解本公开的范围。
在不冲突的情况下，本公开各实施例及实施例中的各特征可相互组合。
如本文所使用的，术语“和/或”包括一个或多个相关列举条目的任何和所有组合。
本文所使用的术语仅用于描述特定实施例，且不意欲限制本公开。如本文所使用的，单数形式“一个”和“该”也意欲包括复数形式，除非上下文另外清楚指出。还将理解的是，当本说明书中使用术语“包括”和/或“由……制成”时，指定存在所述特征、整体、步骤、操作、元件和/或组件，但不排除存在或添加一个或多个其它特征、整体、步骤、操作、元件、组件和/或其群组。
除非另外限定，否则本文所用的所有术语(包括技术和科学术语)的含义与本领域普通技术人员通常理解的含义相同。还将理解，诸如那些在常用字典中限定的那些术语应当被解释为具有与其在相关技术以及本公开的背景下的含义一致的含义，且将不解释为具有理想化或过度形式上的含义，除非本文明确如此限定。
VNF通过MANO对虚拟资源进行管理。针对虚拟机进行部署或容量调整、针对相关网络资源进行操作等一系列运维动作都需要从MANO上发起。为了使MANO能够更好地服务于VNF、针对VNF发起的资源操作采取合适的应对措施，MANO需要充分、及时地了解VNF相关的虚拟资源属性及状态。例如，用户希望将某VNF下的某个虚机从主机A节点迁移到主机B节点，但是，在用户操作该虚拟机迁移之前，该虚机由于其他一些外界原因(例如主机维护，人为 操作等)，已经处于迁移过程中或者已经迁移到主机B节点。如果MANO不能感知到该虚机相关的虚拟资源属性及状态的变化，就无法采取合适的操作措施，也就无法为用户提供较好的资源操作支持。
为了解决上述问题，在一些相关技术中，MANO中存在一个虚拟资源管理的模块或者组件。该模块或者组件通常以固定的频率与各云平台交互，以此来感知云平台上虚拟资源的变化情况。
本公开的发明人经研究发现，以固定的频率与云平台交互的策略有较大的局限性。具体来说，以一个固定频率的同步信息的策略往往造成最差情况下MANO需要等待一个完整的同步周期才能感知到虚拟资源属性及状态的变化，而这种滞后性往往导致一些不可预知的错误。例如，虚机已经处于迁移状态中，若MANO由于需要等待同步周期而没有及时感知到该虚机相关的虚拟资源属性及状态的变化，当用户希望将该虚机从主机A节点迁移到主机B节点时仍然会通过MANO下发迁移请求，云平台接收到迁移请求后就会返回操作冲突之类的错误，而该错误会让用户感到困惑。
在一些相关技术中，通过提高同步频率来提升MANO感知虚拟资源属性及状态变化的及时性。本公开的发明人认为，提高同步频率会产生巨大的代价。具体来说，因为MANO系统资源有限，提高同步频率意味着更多的资源消耗，会导致正常的生命周期业务受到影响；MANO与云平台是一对多的关系，如果众多的云平台中某个平台出现暂时的性能瓶颈，该云平台的响应会变慢，那么以一个较高的频率频繁地与该云平台交互会进一步加重该云平台的性能问题。因此，通过提高同步频率来提升MANO感知虚拟资源属性及状态变化的及时性并不是优越的解决方案。
有鉴于此，第一方面，参照图1，本公开实施例提供一种虚拟资源信息的同步方法，包括步骤S100和S200。
在步骤S100中，确定资源同步策略，所述资源同步策略表征至少一个租户的优先级，其中，不同优先级对应的同步租户的虚拟资源信息的同步频率不同。
在步骤S200中，根据所述资源同步策略同步所述至少一个租户的虚拟资源信息。
在本公开实施例中，将云平台以租户进行分割，每一个云平台看做租户的集合体。需要说明的是，在本公开实施例中，可以是一个云平台上的全部租户的虚拟资源由同一个MANO进行管理，也可以是一个云平台上的部分租户的虚拟资源由一个MANO进行管理。本公开实施例对此不做特殊限定。其中，步骤S100中所述的至少一个租户归属于至少一个云平台，且步骤S100中所述的至少一个租户均由同一个MANO进行管理。在步骤S200中，以租户为单位进行虚拟资源信息的同步。
图2中(a)为以云平台为单位进行虚拟资源信息同步时资源消耗的示意图，图2中(b)为以租户为单位进行虚拟资源信息同步时资源消耗的示意图。如图2所示，在本公开实施例中，以租户为单位进行虚拟资源信息同步，将同步虚拟资源信息的规模从云平台级别下降到租户级别，从而使得MANO系统的资源消耗从单个时间点突发型消耗转变为全时段的平缓型消耗。
需要说明的是，在本公开实施例中，通过步骤S100确定资源同步策略，使得各个租户对应的优先级是动态可调的。在步骤S200中，根据资源同步策略同步租户的虚拟资源信息，即按照各个租户的优先级所对应的同步频率，从各个租户归属的云平台同步虚拟资源信息。其 中，不同优先级的租户对应的同步频率不同，从而实现对不同租户的虚拟资源信息按照差异化的同步频率进行同步。同一租户的优先级可以是动态变化的。通常，但非必须地，租户的优先级越高，对应的同步频率越高。
本公开实施例提供的虚拟资源信息的同步方法中，以租户为单位进行虚拟资源信息同步，将MANO系统的资源消耗转变为平缓型消耗，减小了虚拟资源信息同步对MANO系统正常的生命周期业务的影响；不同租户的同步频率相互独立且动态可调，使得MANO系统能够根据云平台性能、用户操作等因素差异化同步各个租户的虚拟资源信息，有利于提升虚拟资源同步的及时性，降低对云平台性能的影响，从而更好地支持用户在VNF中进行的资源操作。
在一些实施例中，通过对针对租户的用户操作进行预测，根据预测的用户操作确定租户的优先级，从而确定能够满足VNF后续业务需求的同步频率。例如，对针对租户进行虚拟机部署、升级、容量调整等重大操作进行预测，在预测到用户可能针对租户进行虚拟机部署、升级、容量调整等操作时，提升同步该租户的虚拟资源信息的频率，及时同步该租户的虚拟资源信息，从而能够及时感知虚拟机部署、升级、容量调整等操作导致的虚拟资源属性、状态等的变化，在VNF后续业务过程中避免同步不及时导致的操作冲突等问题。
相应地，在一些实施例中，参照图3，确定资源同步策略的步骤S100可进一步包括步骤S110。
在步骤S110中，对针对租户的用户操作进行预测，根据预测结果确定租户的优先级。
本公开实施例对于用户操作不做特殊限定。在一些实施例中，用户操作是能够使租户的虚拟资源的属性、状态产生较大变化的操作，例如租户虚拟机部署、升级、容量调整、迁移等。
本公开实施例对如何对用户操作进行预测不做特殊限定。
经本公开的发明人研究发现，在实际运用场景中每个VNF都归属于不同的租户；实际场景中虚拟机部署、升级、容量调整等重大操作对应的MANO业务通常是根据现场的时间规划来串行执行，即每个VNF的用户操作是串行执行的，时间上不会冲突，并发执行重大操作的可能性非常小；在执行虚拟机部署、升级、容量调整等重大操作之前，通常需要对环境当下的情况进行巡检，巡检内容包括确认相关虚拟资源的状态等，在巡检过程中VNF会触发对租户的虚拟资源信息的查询；在用户操作结束后，为确保VNF资源状态达到预期，也会触发对VNF租户下虚拟资源信息的查询。
基于上述研究，在本公开实施例中，能够根据VNF查询租户的虚拟资源的频率，进而对用户操作进行预测。例如，如果VNF主动要求查询某云平台某租户下的虚拟资源信息，查询频率越高，针对该租户发生虚拟机部署、升级、迁移、容量调整等重大操作的可能性越大，因此需要提升该租户的优先级，以此来满足VNF后续的业务要求。
相应地，在一些实施例中，参照图4，对针对租户的用户操作进行预测，根据预测结果确定租户的优先级的步骤S110可进一步包括步骤S111和S112。
在步骤S111中，确定虚拟网络功能VNF发送资源查询请求的查询频率，所述资源查询请求用于查询租户的虚拟资源信息，所述查询频率表征针对租户的用户操作。
在步骤S112中，根据所述查询频率确定租户的优先级。
本公开实施例对于如何确定查询频率不做特殊限定。在一些实施例中，可以确定一定的时间间隔内查询租户的虚拟资源信息的次数，进而确定查询频率。
本公开实施例对于如何根据查询频率确定租户的优先级不做特殊限定。
相应地，在一些实施例中，参照图5，根据所述查询频率确定租户的优先级的步骤S112可进一步包括步骤S1121和S1122。
在步骤S1121中，在所述查询频率未达到第一阈值的情况下，将租户的优先级确定为第一优先级。
在步骤S1122中，在所述查询频率达到所述第一阈值的情况下，将租户的优先级确定为第二优先级。
其中，所述第一优先级对应的同步频率小于所述第二优先级对应的同步频率。
在一些实施例中,初始各个租户的优先级均为普通级别，第一优先级即为普通级别，第二级别为较优先级别，其中，普通级别对应的同步频率小于较优先级别对应的同步频率。
相应地，在一些实施例中，参照图5，根据所述查询频率确定租户的优先级的步骤S112还可进一步包括步骤S1123和S1124。
在步骤S1123中，在所述查询频率达到所述第一阈值的情况下，确定第一占比，所述第一占比为第一预设时长接收到的全部查询请求中所述VNF发送的资源查询请求的比例。
在步骤S1124中，在所述第一占比达到第二阈值的情况下，将租户的优先级确定为第三优先级；其中，所述第二优先级对应的同步频率小于所述第三优先级对应的同步频率。
在一些实施例中，第三优先级为最高级别，其对应的同步频率为最大的同步频率。在一些实施例中，当租户的优先级为第三优先级时，则立即执行同步该租户的虚拟资源信息的同步任务。
在本公开实施例中，预测用户操作的预测函数可以是MANO系统中默认的预测函数，也可以是外部注入的预测函数。本公开实施例对此不做特殊限定。
相应地，在一些实施例中参照图6，对针对租户的用户操作进行预测，根据预测结果确定租户的优先级的步骤S110可进一步包括步骤S113和S114。
在步骤S113中，获取用户行为预测函数。
在步骤S114中，根据所述预测函数对针对租户的用户操作进行预测，以确定租户的优先级。
在一些实施例中，根据VNF查询租户的虚拟资源信息的查询频率确定租户的优先级时，获取外部注入的预测函数是指获取外部配置的第一阈值和第二阈值等参数。
在一些实施例中，根据云平台的性能动态调整云平台所属租户的优先级，进而调整云平台所述租户对应的同步频率。在本公开实施例中，根据云平台的响应能力表征云平台的性能。
相应地，在一些实施例中，参照图7，在步骤S100中，确定资源同步策略的步骤可进一步包括步骤S120和S130。
在步骤S120中，获取至少一个云平台的响应能力信息。
在步骤S130中，根据所述至少一个云平台的响应能力信息确定各个所述云平台所属的租户的优先级。
在本公开实施例中，在云平台出现性能瓶颈而导致响应能力下降时，将云平台所属的租户的优先级调整为对应较低同步频率的优先级，从而根据云平台的响应能力差异化同步租户的虚拟资源信息的频率，能够缓解云平台的性能瓶颈问题。
本公开实施例对于如何获取云平台的响应能力不做特殊限定。
在一些实施例中，参照图8，获取至少一个云平台的响应能力信息的步骤S120可进一步包括步骤S121和步骤S122。
在步骤S121中，调用云平台获取token接口。
在步骤S122中，确定云平台的响应时间作为所述响应能力信息。
本公开实施例对于如何根据云平台的响应能力不做特殊限定。
在一些实施例中，参照图9，根据所述至少一个云平台的响应能力信息确定各个所述云平台所属的租户的优先级的步骤S130可进一步包括步骤S131。
在步骤S131中，在云平台的响应时间超过第三阈值的情况下，将云平台所述租户的优先级确定为第四优先级，其中，所述第四优先级对应的同步频率小于租户原本的同步频率。
本公开实施例对于如何执行步骤S131不做特殊限定。例如，可以设定第四优先级对应一个特定同步频率，该特定同步频率为最小的同步频率；也可以设定第四优先级的租户的频率按照预定比例减小，例如，将第四优先级的同步频率设置为其原同步频率的一半。
在一些实施例中，还能够对资源同步策略的有效性进行评价，并能够在资源同步策略的有效性不满足要求的情况下对资源同步策略进行更新，从而形成闭环效果。
相应地，在一些实施例中，参照图10，确定资源同步策略的步骤S100可进一步包括步骤S140和S150。
在步骤S140中，确定所述资源同步策略的有效性信息。
在步骤S150中，根据所述有效性信息更新所述资源同步策略。
在一些实施例中，参照图11，确定所述资源同步策略的有效性信息的步骤S140可包括步骤S141。
在步骤S141中，确定第二预设时长中接收到的资源查询请求对应的租户与所述资源同步策略中优先级为第二优先级的租户的吻合率，得到所述有效性信息；其中，第一优先级对应的同步频率小于所述第二优先级对应的同步频率,所述第二优先级对应的同步频率小于第三优先级对应的同步频率。
在一些实施例中，参照图11，根据所述有效性信息更新所述资源同步策略的步骤S140可进一步包括步骤S151和S152。
在步骤S151中，在吻合率大于第四阈值、小于第五阈值的情况下，将第二优先级的租户确定为第一优先级。
在步骤S152中，在所述吻合率小于(或等于)第四阈值的情况下，取消第三优先级的租户，将第二优先级的租户确定为第一优先级。
在一些实施例中，在吻合率大于第五阈值的情况下，判定资源同步策略有效。

为了使本领域技术人员能够更清楚地理解本公开实施例提供的技术方案，下面通过具体的实施例，对本公开实施例提供的技术方案进行详细说明。
实施例
在本实施例中，MANO正常运行，MANO与云平台之间通信正常。
图15是本实施例中虚拟资源信息同步的架构示意图。如图15所示，虚拟资源信息同步的架构包括VNF业务模块、资源管理模块、行为预测模块、资源环境监测模块、更新策略决策模块、更新策略准确度评价模块。
图16是基于图15所示的虚拟资源信息同步的架构中，各业务模块的交互示意图。
在本实施例中，MANO从云平台同步租户的虚拟资源信息的过程包括以下步骤：
1.MANO系统运行过程中，VNF业务模块向资源管理模块发送查询某租户资源的资源查询请求；
2.资源管理模块将该请求涉及的租户及资源类别信息发送给用户行为预测模块；
3.用户行为预测模块执行行为预测函数，如无外部注入预测函数，则使用内置默认预测函数，初始所有租户资源查询的优先级均为普通级别。其具体规则(步骤)如下：
3.1记录该次请求的租户及资源类别信息以及时间点；
3.2如果在一定的时间间隔内(默认值为5分钟，可配置)，对该租户的资源查询达到阈值(默认值为10次，可配置)，判定当前用户对该租户资源敏感，将该租户资源查询优先级提升至较优先级别，并记录该信息；
3.3如果在一定的时间间隔内(默认值为5分钟，可配置)，对该租户的资源查询未达到 阈值(默认值为10次，可配置)，判定当前用户对该租户资源不敏感，将该租户资源查询优先级设置为普通级别，并记录该信息；
3.4如果满足3.2的条件，继续检查用户查询的资源类别；
3.5如果查询虚机资源的请求达到时间间隔内所有查询请求一定的百分比(默认值为80％，可配置)，则生成该租户下全量查询虚机任务，并将此任务优先级提升到最高级别，并记录该信息；
3.6如果资源管理模块在3.5过程之后执行了全量虚机查询任务，则清除3.5中记录的信息。
4.行为预测模块将用户行为预测的结果发送给更新策略决策模块；
5.资源环境监测模块定时执行监测函数，如无外部注入监测函数，则执行默认监测函数。其具体规则(步骤)如下：
5.1调用云平台获取token接口，记录响应时间；
5.2如果出现响应时间超过0.5秒的云平台，则将其标记为性能较差平台，并记录该信息；
5.3如果响应时间在0.5秒以内，则标记为正常平台，并记录该信息。
6.资源环境监测模块将资源环境监测的结果发送给更新策略决策模块；
7.更新策略决策模块根据第4步和第6步的信息，得出资源同步策略，该策略提示资源管理模块立即执行云平台中最高级别的资源同步任务，并以10秒(时间可配置)为间隔，同步较高优先级下租户资源信息，以2分钟(时间可配置)为间隔，同步普通级下租户资源信息；同时对于性能较差的平台，其间隔时间加倍(时间可配置)；
8.更新策略准确度评价模块从更新策略决策模块查询当前的策略内容，并从资源管理模块查询固定时间段(时间可配置，默认1分钟)内VNF业务模块向资源管理模块发送的资源请求，根据评价函数来判断更新策略的有效性，评价函数可以外部注入，如不注入的话，评价函数的规则如下：
8.1判断1分钟内请求查询资源涉及的租户是否与策略中指定的租户相吻合，吻合度大于70％(默认值，可配置)以上则认为更新策略有效，如介于50％--70％，则认为需要将较优先级租户调整为普通租户，如小于50％，则认为需要将较优先级租户调整为普通租户，并同时取消掉高优先级任务要求。
9.更新策略准确度评价模块将评价结论发送给更新策略决策模块，更新策略决策模块据此调整规则，具体调整方案在8.1中已描述。
