Description

虚拟网络的调节方法及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种虚拟网络的调节方法及系统。
背景技术
在一个实际运行的物理网络中，由于业务或者工作负荷的变化，往往需要对网络中的服务器的能力，网络连接带宽，以及网络的出口带宽等进行调节，一般是增加，或者进一步增加更多的服务器和/或更多的网络设备等。这些调节工作，一般都是由网络管理员来进行监测和处理；或者进一步需要提供网络出口连接的运营商来协助完成调节。
对应的，在数据中心提供的虚拟网络(Virtual Network，简称为VN)运行方面，同样也会面临这些调节的问题。由于这些资源一般都是VN服务提供商提供，所以VN的动态调节，可能面临不同的问题，需要与服务提供商的更多的交互。
图1是根据相关技术中的VN业务提供网络的示意图，如图1所示，示出了典型的VN使用环境。
在图1中，多个虚拟机(Virtual Machine，简称为VM)连接到网络虚拟化边缘(设备)(Network Virtualization Edge，简称为NVE)，并进一步与NVE中的该VN的虚拟路由转发功能(Virtual Routing and Forwarding，简称为VRF)进行关联，不同的VRF实现VN的网络连接。进一步，VN可以通过NVE和互联网实现连接。如图1中的虚线部分所示。
一般而言，在虚拟网络的运行过程中，可以通过(虚拟)网络设备本身，或者相关的服务软件的支持，进行网络的性能和有关参数的监测，并将监测结果形成报告，提供给网络管理员。网络管理员，可以根据这些性能报告，以及有关的业务规划和预测，进行相关的调节，以满足网络的功能和性能要求。
进一步，还可以在网络中，设置(性能)管理服务器，集中监测VN的各有关的部分的参数，或者运行的性能参数值。并可以设置相关的阈值，以帮助管理员进行动态调节。
具体的，虚拟网络中可以调节的指标和/或参数，可以包括但不限于：
1)网络带宽，包括：INTERNET出口；VM和/或服务器的连接带宽；NVE之间的网络连接带宽；等等。
2)处理能力，例如更高速的CPU，或者申请更多的CPU。
3)存储空间，例如更大的存储空间，包括内存和/或外存。可以申请存储空间更大的存储器，或者申请更多的存储器；或者也可以通过网络存储进行调节增加等。
4)增加能够处理的功能类型，或者功能软件包，或者软件功能等。
5)动态迁移。以及，
6)备份等高可靠性措施，等等。
在相关领域的技术条件下，网络管理员，根据性能监测以及有关阈值的设置，或者根据网络规划的要求，可以将有关的调节需求，通过VN提供商的需求收集系统，提交给VN提供商。再由VN提供商的网络管理员，将有关调节需求，具体对应到有关的设备，进行有关的设备准备或者参数的配置/重新配置，来实现具体的调节。
这样的过程，一般而言，往往使得调节延时比较大，且步骤比较复杂。
针对相关技术中对虚拟网络中的指标和/或参数进行调节的方式延时较大、且调节步骤较复杂的问题，目前尚未提出有效的解决方案。

具体实施方式
下文中将参考附图并结合实施例来详细说明本发明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
考虑到由于VM等，都是由VN提供商提供的，因此在本实施例中，提供了一种实现虚拟网络的动态调节和部署的方法和系统，由VM直接向VN提出动态调节申请，并通过VN开展系统，对该申请(也称请求，需求)进行认证，一旦通过认证，可以进行直接的调整。这种调节方式步骤简单，能够提高业务提供的效率，以及方便用户的使用和动态满足用户的需求。
在本实施例中，提供了一种虚拟网络的调节方法，图2是根据本发明实施例的虚拟网络的调节方法的流程图，如图2所示，该方法包括如下步骤：
步骤S202，预设VN的性能参数/指标的阈值；
步骤S204，获取所述VN的性能参数/指标的值；
步骤S206，在所述性能参数/指标值达到所设阈值时，触发所述VN中的相关网络实体发送用于调节虚拟网络VN的所述性能参数/指标的调节请求给VN业务开展系统；
步骤S208，所述VN业务开展系统对所述调节请求进行认证，并在认证通过后将确定的性能参数/指标调节值发送给相关调节设备进行调节。
本实施例通过上述步骤，在VN的性能参数/指标的值满足预设的触发阈值的情况下，触发VN中的相关网络实体自动发起调节VN的性能参数/指标的动态调节请求给VN业务开展系统，然后VN业务开展系统对该调节请求进行认证，并在认证通过后由相关调节设备进行调节，从而无需经过VN提供商的网络管理员进行配置调节，而是根据VN的性能参数/指标值主动发起进行调节的请求，解决了相关技术中对虚拟网络中的指标和/或参数进行调节的方式延时较大、且调节步骤较复杂的问题，提升了虚拟网络的指标和/或参数调节的反应速度，能够提高业务提供的效率，方便用户的使用和动态满足用户的需求。
需要说明的是，上述预设的触发阈值可以是性能参数达到预设的参数值或者参数比例，或者，也可以是性能参数达到预设的参数值或者参数比例，并且超过指定时长。当然也可以是其他的阈值触发方式，并不限于本实施例中提到的几种。

本实施例中，对于触发VM发起所述用于调节VN的性能参数/指标的申请的流程具体如下：
在所述VN业务开展系统对所述调节请求进行认证的过程中，如果所述调节请求用于调节VM自身的性能参数/指标的情况下，则所述VN业务开展系统在所述调节请求通过认证后向VM协同系统发送请求信息；所述VM协同系统将所述请求信息发送给所述VM所在的主机并由所述主机实施调节及返回调节结果，主机通过上述VM管理程序实施调节。其中，VN业务开展系统向VM协同系统发送的所述请求信息可以 依照VM协同系统支持的格式发送，该请求信息可以与上述调节请求相同，也可以不同，根据实际情况确定，本实施例中并不对其进行限定。
而如果所述调节请求用于调节VM的非自身的性能参数/指标，则所述VN业务开展系统在所述调节请求通过认证后向所述相关调节设备发送所述调节请求，并由所述相关调节设备实施调节。
需要说明的是，上述认证结果中，携带有确定调节的性能参数/指标的具体的调节值，NVE按照该调节值进行调节。该调节值通常可以与所述调节请求中携带的性能参数/指标的调节值相同，当然，也可以与所述调节请求中携带的调节值不相同，所述调节请求中也可以不携带调节值，由认证结果直接确定。
本实施例中，在步骤S202中可以通过所述VN中的VM或者NVE或者网关设备中的性能监测模块获取所述VN的性能参数/指标值。进一步地，所述VN中可以设置性能监测服务器，所述性能检测模块将获取到的所述VN的性能参数/指标值发送给所述VN中的性能监测服务器进行收集；然后根据策略，设置所述性能监测服务器是否代替所述VN中的相关网络实体在所述性能参数/指标值达到所述阈值时发送所述调节请求；如果是，则所述VN中的性能监测服务器可以在所述性能参数/指标值达到所述阈值时发起所述调节请求，如果否，则可以由所述性能检测模块所在的相关设备(例如上述VM或者NVE或者网关设备等)自行发起所述调节请求。其中，所述性能监测服务器是所述相关网络实体的一种。
其中，如果是通过性能监测服务器发送所述调节请求，则所述性能监测服务器可以发送所述调节请求给运营商的需求收集系统/门户系统，并由所述需求收集系统/门户系统将所述调节请求发送给所述VN业务开展系统；或者，所述性能监测服务器也可以直接将所述调节请求发送给所述VN业务开展系统。
在本实施例中，可以为NVE-NVA协议以及VM-NVE协议中新增一条专用于表示支持本实施例的调节方法的属性，在本实施例中称为自动调节字段/属性。具体如下：

在以下优选实施例中，提供了一种数据中心中虚拟网络动态部署的实现方法和系统。具体地，对VM的动态调节的处理，可以包括：
在VM中安装性能监测模块，监测VM的性能，并设置相关的阈值。
进一步，对VM性能监测模块，可以设置动态调节的属性值。在指标达到阈值时，可以自动触发VM进行动态调节申请(即上述调节请求)。
所述VM动态调节申请，可以通过NVE自动发现协议，传递申请给NVE。
NVE提取VM的动态调节申请，并将该申请发送给NVA，进一步，由NVA/NVE协同对动态调节申请进行认证。如果通过认证，则可以接受申请(其中还可以确认所述动态调节的参数，确认结果的参数可能和原申请中的不一致，根据策略确定。但是通常为申请提出的参数)，并进一步通过NVA-NVE协议，传回NVE，由NVE来进行有关的参数调节。
其中，所述NVA具有支持VN客户进行动态申请的属性。
进一步，对涉及VM本身调节的申请，需要进一步将需求通过NVA发送给虚拟机协同系统，实现调节。完成调节后，将结果再通过NVA返回。
对于由NVE进行性能测量并发起的动态调节，可以直接通过NVE-NVA接口发送给NVA实现需求的认证和调节。
进一步，对涉及的网络设备，例如NVE，或者网关设备等自身无法提出调节申请的设备，可以通过在VN中设置性能监测服务器，收集VN的有关性能数据，并设定相应的阈值，根据设定的阈值，在性能指标达到设定的阈值时，直接发送调节申请给运营商的需求收集系统/门户系统，再由门户系统将需求发送给NVA实现调节。
进一步，为优化调节性能，可以通过特别设计的NVE-NVA参数，实现VN向NVA直接提出调节申请。
需要说明的，图3中为表达方便区分了相关的网络实体和相关调节设备。在某些情况下，这两者是同一设备，例如NVE既可以发起调节需求，也可以作为调节设备实施调节。
下面结合附图对本优选实施例进行详细说明。
在下列各实施案例中，需要在VM中，或者有关的NVE设备中，安装性能监测装置/系统(在以下优选实施例中可以通过软件来实现)。所述性能监测软件，可以设置相关的阈值；并进一步，根据需要可以设置性能监测软件，支持提出有关性能指标进行调节的申请功能。
为支持动态调节功能，NVA中的有关VN属性需要包括自动调节属性，在设置了该属性后，即可支持VN的自动调节。并进一步设定有关调节参数的策略信息。
实施例一：VM自动发起调节申请(一)
图4是根据本发明优选实施例一的VM自动发起调节申请的流程示意图一，如图4所示，本实施例中，涉及到调节的参数是VM的连接带宽。该调节，可以通过NVE实现。
步骤S402，VM中安装性能监测软件，对性能进行监测。并设置性能阈值。且VM具有自动申请调节的功能。例如，具体的参数，可以是VM的连接带宽使用信息，如果达到标称带宽的70％，且持续时间达到5分钟，或者30分钟(这个时间，或者阈值的设置策略，根据客户的具体需求来确定)，则需要对带宽进行调节。
步骤S404，在VM的性能达到设定的阈值时，启动自动调节申请。一般是通过协议报文的发送来实现。
步骤S406，VNE在收到相关报文后，提取有关申请及参数信息。并向NVA提交自动调节申请，并对该申请进行认证。
步骤S408，认证通过后，返回相关的申请结果，以及有关的参数和配置/操作命令。
步骤S410，NVE进行有关命令的执行，实现调节。
步骤S412，NVE调节完成后，将有关调节结果和调节参数，发送给NVA进行备案。
步骤S414，NVE返回调节结果给VM。
实施例二：VM自动发起调节申请(二)
图5是根据本发明优选实施例二的VM自动发起调节申请的流程示意图二，如图5所示，本实施例的典型场景是，VM申请调节的内容，涉及到其自身的改变或者调整，具体的调节参数包括，提高主频，和/或者增加CPU的个数，和/或者增加存储器，包括内存，和/或者外存的容量等。这需要VM协同系统的支持。即，需要NVA将有关的调节需求，进一步发送给虚拟机协同系统(VM OrchSYS)，由该协同系统进一步联系VM所在的VM管理程序来完成VM的调节。
具体的流程包括：
步骤S502，VM中安装性能监测软件，对性能进行监测。并设置性能阈值。且VM具有自动申请调节的功能。例如，具体的参数，可以是VM的CPU使用率，如果使用率达到标称指标的70％，且持续时间达到5分钟，或者30分钟(这个时间，或者阈值的设置策略，根据客户的具体需求来确定)，则需要对相关指标进行调节。
步骤S504，在VM的性能达到设定的阈值时，启动自动调节申请。一般是通过协议报文的发送来实现。
步骤S506，VNE在收到相关报文后，提取有关申请及参数信息。并向NVA提交自动调节申请，并对该申请进行认证。
步骤S508，认证通过后，将有关调节申请及有关的参数发送给虚拟机协同系统。再有该协同系统进一步将调节需求及参数，发送给对应的虚拟机管理程序。
步骤S510，虚拟机管理程序完成相应的调节后，将调节结果及有关参数，发送给虚拟机协同系统，虚拟机协同系统将调节结果，发送给NVA。
步骤S512，NVA将调节结果及参数返回给NVE。
步骤S514，NVE返回调节结果及参数给VM。
需要说明的是，由于VM和VM管理程序之间具有相互的依存关系，有关调节结果，可以直接传递给VM。但是，调节结果通常还是需要通过本优选实施例中的流程，报告给NVA和NVE，指示执行的结果。这样能够避免导致NVE有一个挂起的进程，即等待VM调节的结果。
需要进一步说明的是，在具体的应用中，可能遇到VM管理程序并不直接支持VM升级的情况，需要通过起一个新的VM(满足性能调节后的要求)，然后通过VM迁移的形式来实现VM的性能指标调节。这样保证本实施例的普遍适应性。
实施例三：NVE发起的调节申请
NVE自身，也可以支持对VN的网络流量信息进行监测，在性能达到标称指标的设定值后，自动发起标称的调节申请。
具体的流程，和优选实施例一中的对VM的带宽调整过程类似，NVE监测到性能参数满足阈值的情况下，向NVA发送调节申请，并携带有关调节的参数。
其他过程类似，在本实施例中不在赘述。不同的NVE之间的调节，例如涉及到对端的NVE的标称调节，则在认证调节申请成功之后，还需要进一步，将有关的调节的需求和指标发送到相关的NVE。
完成调节后，发送调节结果给NVA。
实施例四：性能监测服务器发起的调节申请
图6是根据本发明优选实施例四的由性能监测服务器发起调节申请的网络示意图，如图6所示，对于VN中涉及到的一些网络设备，例如NVE，或者网关设备等自身无法提出调节申请的设备，可以在VN中部署性能监测服务器，并由它协同VN的性能监测，例如收集由VM，和/或者NVE测量的网络性能数据，并设置相关的性能阈值，在相关的网络性能指标达到阈值时，由性能监测服务器发起调节的申请。
在本设施例中，由于NVA对VN客户而言是私有网络设备，因此性能监测服务器发起的请求，需要送到VN提供商的门户(而不能直接送给NVA)，由该门户再将有关调节需求发送给NVA。NVA需要对该调节需求进行身份认证，在论证通过后，再将需要发送给相关的NVE，和/或者相关的虚拟机管理程序，实现调节。
在实现调节后，NVA分别收集调节的执行结果，并通过门户网站，将调节执行结果返回给性能监测服务器。
需要进一步说明的是，NVA将有关调节需求送达NVE或者相关的VM管理程序，可以通过在调节请求中携带有这些设备的相关的地址信息实现。该地址信息可以在性能测量的过程中获得。
需要说明的是，为优化调节性能，可以通过特别设计的NVE-NVA参数，实现VN向NVA直接提出调节申请。
实施例五：性能监测服务器代理发起的调节申请
由于VN业务提供商，可以提供数以百万级的VN，因此如果每个VN都部署一个性能监测服务器，则需要百万级的性能监测服务器。进一步，一般而言，这个性能监测服务器，并不需要多高的性能，因此，可以集中设置一个性能监测服务器，为多个VN进行服务。这样可以进一步优化VN业务的开展。
具体的调节实现，是VN中的VM和NVE等将性能数据发送给集中的监测服务器。一种实现方法是，通过NVE的特别报文发送。阈值设置和触发条件，都和前述实施例一致。
当然，这个集中的监测服务器，需要对不同用户的信息安全进行保障，即一般通过隔离来实现。并且，所述调节需求中包括所属VN的信息，以保证调节的正确、安全地实施。
在另外一个实施例中，还提供了一种软件，该软件设置为执行上述实施例及优选实施例中描述的技术方案。
在另外一个实施例中，还提供了一种存储介质，该存储介质中存储有上述软件，该存储介质包括但不限于光盘、软盘、硬盘、可擦写存储器等。
显然，本领域的技术人员应该明白，上述的本发明的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，可选地，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本发明不限制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
