背景技术
随着虚拟化技术的飞速发展,网络功能虚拟化(英文:network function virtualization,缩写:NFV)技术也越来越重要。NFV技术是指对虚拟网络功能(英文:virtualized network function,缩写:VNF)进行实例化(英文:instantiate),使得该VNF能够运行在通用的物理设备上,从而通过该通用的物理设备,实现网络中专用的网元设备的功能。例如,对服务网关(英文:serving gateway,缩写:SGW)功能进行实例化,以使得SGW功能能够运行在通用的物理设备上,从而通过该通用的物理设备,实现SGW的功能。
现有技术中,通过NFV对VNF进行实例化(英文:instantiate)的流程为:当虚拟网络功能管理节点(英文:virtualized network function manager,VNFM)接收到VNF实例化请求(英文:instantiate VNF)后,VNFM指示网络功能虚拟化调度节点(英文:network function virtualization orchestrator,缩写:NFVO)为待实例化的VNF分配资源,且该VNFM为该VNF配置部署参数,以完成该VNF的实例化,以及该VNFM指示网元管理节点(英文:element manager,缩写:EM)为该VNF配置应用参数,使得该VNF能够运行,且该VNFM通知网络管理节点(英文:network manager,缩写:NM)该VNF的实例化已完成,从而该NM使用该VNF参与组成相应的网络服务(英文:network service,缩写:NS)。
然而,由于EM为VNF配置应用参数时可能会配置失败,从而导致该VNF无法正常运行。因此,若按照上述流程,即使上述应用参数配置失败,在VNFM通知NM该VNF的实例化完成后,NM仍然会认 为该VNF能够正常运行,并使用该VNF参与组成相应的NS,从而导致由该VNF参与组成的NS无法正常运行。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。
在介绍本发明实施例提供的确定VNF的处理策略的方法之前,首先对本发明实施例提供的确定VNF的处理策略的方法涉及的系统进行简单的介绍。如图1所示,为本发明实施例提供的NFV系统框图。
NFV系统主要包括:NFVO、VNFM、虚拟机基础设施管理节点(英文:virtualized infrastructure manager,缩写:VIM)、运营支撑系统(英文:operations support system,缩写:OSS)或业务支撑系统(英文:business support system,缩写:BSS)、EM、VNF节点、虚拟网络功能基础设施(英文:network function virtualization infrastructure,缩写:NFVI),其中,NFVO、VNFM以及VIM构成了NFV系统的管理编排(英文:NFV management and orchestration,缩写:NFV-MANO)域。
其中,NFVO用于对VNF及其对应的NFVI进行部署、操作、管理及协调,以及于对NS生命周期进行管理。
VIM是基础设施和资源的管理入口,能够提供基础设施相关的硬件和虚拟化资源的配置维护、资源监控、告警、性能管理等功能。
NFVI是网络功能虚拟化所需的计算、存储和网络资源的统称。
VNFM用于对VNF的生命周期管理,如实例化、扩展或收缩、查询、更新及终止等。
需要说明的是,本发明实施例中提到的VNF是指已由VNFM配置完部署参数的VNF节点,即本发明实施例中提到的VNF实例化已完成可以理解为VNFM已为该VNF配置完成部署参数;实例化后的VNF可以理解为已由EM配置完应用参数的VNF节点,该VNF节点能够实现相应功能,例如,运行在虚拟机(英文:virtual machine,缩写:VM)上的一个能够实现SGW功能的节点。
EM用于对该NFV系统中的所有VNF进行应用相关的参数配置。
NM用于对NS的生命周期进行管理,如实例化、扩展或收缩、查询、更新及终止等。
需要说明的是,在本发明实施例中NM具体可以为OSS或BSS,或者OSS或BSS的用户操作界面。
在本发明实施例中,NFV系统可以应用于长期演进(英文:long term evolution,缩写:LTE)通信系统中,也可以应用于LTE的演进通信系统中,如LTE-A(英文全称:long term evolution advanced)系统等,本发明不作限制。
实施例一
本发明实施例提供一种确定VNF的处理策略的方法,如图2所示,该方法可以包括:
S101、管理节点接收EM发送的配置反馈消息,该配置反馈消息用于指示VNF的应用参数是否配置成功。
其中,配置反馈消息中包含指示VNF的应用参数配置成功的信息,或者包含指示VNF的应用参数配置失败的信息。示例性的,可以在该配置反馈消息中设置一个特定的标志位,当该标志位为1时,该配置反馈消息用于指示VNF的应用参数配置成功,当该标志位为0时,该配置反馈消息用于指示VNF的应用参数配置失败。
S102、管理节点根据该配置反馈消息,确定对该VNF的处理策略,该处理策略用于管理节点对该VNF进行处理。
需要说明的是,在本发明实施例中,管理节点可以为NM,也可以为VNFM。管理节点接收的配置反馈消息中可以携带VNF的标识,从而管理节点在接收到配置反馈消息后,可以根据该配置反馈消息,确定对VNF的处理策略,其中,该VNF为与该配置消息中携带的VNF的标识对应的VNF。
其中,该配置反馈消息可以为该VNF接收到EM发送的应用参数配置消息后返回给该EM的响应消息,即VNF接收到EM发送的应用参数配置消息后,根据该应用参数配置消息配置该VNF的应用参数,并根据配置结果生成配置反馈消息,以及将该配置反馈消息发送至 EM。进而,EM再将该配置反馈消息转发给管理节点.
进一步的,该处理策略可用于管理节点指示NFVO对该VNF进行相应的处理。
具体的,第一方面,当管理节点为NM时,NM接收到配置反馈消息后,若该配置反馈消息指示VNF的应用参数配置成功,则NM根据该该配置反馈消息确定的对该VNF的处理策略可以为:NM指示NFVO使用该VNF参与组成NS。即NM接收到配置反馈消息后,若NM根据该配置反馈消息确定该VNF的应用参数配置成功,则NM确定可以指示NFVO使用该VNF参与组成NS。
其中,NM指示NFVO使用该VNF参与组成NS可以理解为NM指示NFVO对未实例化的NS进行实例化,以使得该VNF参与组成该NS,从而实现对该NS的实例化;也可以理解为NM指示NFVO对已经实例化的NS进行扩展,以使得该VNF成为该NS的组成部分,即使得该VNF参与组成该NS;还可以理解为NM指示NFVO对已经实例化的NS进行更新,以使得该VNF取代组成该NS的某个VNF,从而使得该VNF参与组成该NS等操作。为了更好的说明本发明实施例中,NM指示NFVO使用该VNF参与组成NS的具体过程,下面以NM指示NFVO对NS进行实例化为例,进行示例性的说明。
例如,当NM需要对由该VNF参与组成的NS进行实例化时,NM可以向NFVO发送NS实例化请求消息,以请求NFVO对该NS进行实例化。该NS实例化请求消息中携带该NS的实例化信息,NFVO接收到该NS实例化请求消息后,NFVO根据该NS实例化请求消息,对满足该NS的实例化信息的多个VNF进行相关的连接操作,从而使得该多个VNF组成该NS,以实现对该NS的实例化。其中,该VNF为满足该NS的实例化信息的多个VNF中的一个。即NM指示NFVO使用该VNF参与组成该NS。
进一步的,在本发明实施例中,由于NM是在接收到EM发送配置反馈消息,且根据该配置反馈消息确定该VNF的应用参数配置成功后,确定可以指示NFVO使用该VNF参与组成NS。其中,应用参 数配置成功即表示该VNF可以正常运行。因此,当NM指示NFVO使用该VNF参与组成NS时,由于该VNF能够正常运行,因此能够保证该NS正常运行。从而避免了现有技术中,NM可能会指示NFVO使用应用参数配置失败的VNF参与组成NS,即使用无法正常运行的VNF参与组成NS,而导致的该NS无法正常运行的问题。
第二方面,NM接收到该配置反馈消息后,若该配置反馈消息指示该VNF的应用参数配置失败,则NM根据该配置反馈消息确定的对该VNF的处理策略可以为:NM指示NFVO释放该VNF占用的资源。即若NM根据该配置反馈消息确定该VNF的应用参数配置失败,则NM可以指示NFVO释放该VNF占用的资源。
其中,NM指示NFVO释放该VNF占用的资源的具体过程可以为:NM向NFVO发送资源释放指示消息,以指示NFVO释放该VNF占用的资源。NFVO接收到该资源释放指示消息后,NFVO向VIM发送资源释放指示消息,请求VIM根据该资源释放指示消息释放该VNF占用的资源,其中,该VNF占用的资源可以包括在该VNF的实例化过程中,分配给该VNF的VM和虚拟连接等资源。
进一步的,在现有技术中,若EM为VNF配置应用参数失败,使得该VNF无法正常运行,则由于该VNF在实例化的过程中已经占用了资源,因此即使该VNF无法正常运行,该VNF仍然会占用这些资源,从而导致这些资源无法被充分利用,进而造成了资源的浪费。而在本发明实施例中当NM接收到EM发送配置反馈消息,且根据该配置反馈消息确定该VNF的应用参数配置失败后,NM能够及时指示NFVO释放该VNF占用的资源,从而避免了现有技术中应用参数配置失败的VNF占用资源,导致资源浪费的问题,进而可以充分利用资源,提高资源利用率。
第三方面,当管理节点为VNFM时,VNFM接收到配置反馈消息后,若该配置反馈消息指示VNF的应用参数配置成功,则VNFM根据该配置反馈消息确定的对该VNF的处理策略可以为:VNFM经由NFVO向NM发送VNF实例化完成消息,NM根据该VNF实例化完成消息指 示NFVO使用该VNF参与组成NS。即若VNFM根据该配置反馈消息确定该VNF的应用参数配置成功,则VNFM向NFVO发送VNF实例化完成消息,由NFVO将该VNF实例化完成消息发送至NM,从而NM可以根据所述VNF实例化完成消息确定该VNF的实例化已完成并且该VNF的应用参数已经配置成功,进而NM可以指示NFVO使用该VNF参与组成NS。
进一步的,在本发明实施例中,由于VNFM在确定该VNF的应用参数配置成功后,才通知NM该VNF的实例化已完成,即该VNF可以正常运行,从而当NM使用该VNF参与组成相关的NS时,能够保证由该VNF参与组成的NS正常运行,因此,避免了现有技术中,由于VNFM在不确定已完成实例化的VNF的应用参数是否配置成功的情况下,通知NM该VNF的实例化已完成,而导致的NM可能会指示NFVO使用应用参数配置失败的VNF参与组成NS,造成该NS无法正常运行的问题。
第四方面,当VNFM接收到配置反馈消息后,若该配置反馈消息指示该VNF的应用参数配置失败,则VNFM根据该配置反馈消息确定的对该VNF的处理策略可以为:VNFM指示NFVO释放该VNF占用的资源。即若VNFM根据该配置反馈消息确定该VNF的应用参数配置失败,则VNFM可以指示NFVO释放该VNF占用的资源。
其中,VNFM指示NFVO释放该VNF占用的资源的方式,与上述NM指示NFVO释放该VNF占用的资源的方式相同,具体可参见上述NM指示NFVO释放该VNF占用的资源的方式,此处不再赘述。
进一步的,在本发明实施例中,当VNFM接收到EM发送配置反馈消息,且根据该配置反馈消息确定该VNF的应用参数配置失败后,VNFM能够及时指示NFVO释放该VNF占用的资源,从而避免了现有技术中应用参数配置失败的VNF占用资源,导致资源浪费的问题,进而可以充分利用资源,提高资源利用率。

可选的,在第二种可能的应用场景中,若NM接收到VNFM发送的VNF实例化完成消息,确定该VNF的实例化已完成,则当NM确定需使用该VNF时,NM会向EM发送VNF应用参数配置通知消息,通知EM为该VNF配置应用参数,从而使得EM接收到NM发送的VNF应用参数配置通知消息后,根据该VNF应用参数配置通知消息的指示,确定为该VNF配置应用参数,进而EM可以向该VNF发送应用参数配置消息,以指示该VNF根据应用参数配置消息配置该VNF的应用参数。
