Description

一种NFV系统业务加速方法、系统、装置及服务器

技术领域
本发明涉及通信领域，尤其涉及一种NFV系统业务加速方法、系统、装置及服务器。
背景技术
遵循虚拟网络功能(Virtual Network Function，NFV)组织标准，通信网络将在通用服务器平台商用现货(Commercial-Off-The-Shelf，COTS)的基础上，利用云(Cloud)的IT技术(如虚拟化等)实现通信网元设备的云化部署，实现硬件资源的动态分配和利用，满足运营商快速部署业务服务能力的要求。
而通用服务器使用的中央处理器(Central Processor Unit，CPU)对于网络数据处理、复杂算法运算的处理能力相对不足，性能较低，为弥补这个短板，需要使用加速设备(如：FPGA等)来辅助进行这些业务的加速处理，进一步提升业务处理性能，降低能耗。而加速设备可以进行分布式部署，实现加速资源的灵活分布和按需分配。
当某个业务类型的业务需要加速时，通过加速引擎运行编程包来对该业务类型进行业务加速服务，运行的该编程包是预先安装在加速引擎中的固定的编程包。
通信设备需要进行加速处理的业务种类繁多，并且会不断根据现实的性能需求进行演进扩展，但由于编程包是预装在加速引擎中的固定的编程包，因此无法对编程包进行扩展，无法满足由于业务多样性带来的可扩展性需求。

具体实施方式
为了使本发明的技术方案及有益效果更加清楚，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
NFV(网络功能虚拟化)是由电信网络运营商提出的，是指用借助IT虚拟化技术，采用业界标准的大容量服务器、存储器和交换机作为通用硬件平台，并在这些通用硬件平台上部署虚拟化、云化软件以承载各种各样的网络软件功能，各种网元作为虚拟网络功能(Virtual  Network Feature，VNF)运行。NFV系统实现了软件的灵活加载，实现在数据中心、网络节点和用户端等各个位置灵活的部署配置，从而加快网络部署和调整的速度，降低业务部署的复杂度，提高网络设备的统一化、通用化、适配性等。
图1为网络功能虚拟化的架构图，包括VNF、MANO、NFVI三个模块。
1、NFV基础设施(NFV Infrastructure，NFVI)：
NFVI为VNF提供硬件资源和虚拟化资源及其管理，以及虚拟化运行环境。NFVI是由软硬件构成的NFV基础设施层，包括由COTS服务器、交换机和存储设备构成的硬件资源和由虚拟化软件层构成的虚拟资源层。虚拟资源层虚拟机的调度引擎叫“Hypervisor”，具体实现上包括开源的KVM、XEN和闭源的EXSi、Hyper-V等。同时，虚拟资源层还提供虚拟交换机(vSwitch)，用来支持虚拟机(Virtual Machine，VM)间以及和外部网络的组网互通能力。
NFVI通过虚拟资源层最终给上层虚拟网络功能使用的资源容器是虚拟机，VNF像使用物理服务器一样使用虚拟机，一个虚拟网络功能通常需要申请多个虚拟机协同工作。
2、NFV管理和编排(Management and Orchestration，MANO)
MANO是衔接NFVI和VNF的核心环节，包括编排(Orchestrator)、虚拟网络功能管理(VNF manager)和虚拟设施管理(Virtualised Infrastructure Manager，VIM)。其中VIM负责管理一个数据中心的所有虚拟资源，常用的VIM包括开源的OpenStack和闭源的Vmware。虚拟网络功能管理负责VNF的生命周期管理，包括初始化、VNF的NFVI资源配置、扩容、减容、拆卸、查询、状态监控等。一个VNF manager通常管理一个或多个VNF，而一个MANO系统通常包括多个VNF manager。Orchestrator完成由多个VNF组合的网络服务的生命周期管理和对VIM提供的资源进行统一调度。
3、虚拟网络功能(Virtualised Network Function，VNF)，也称虚拟化逻辑网元
VNF是指各种虚拟化的网络功能，这些网络功能传统上运行在各种专用硬件上，虚拟化后运行在由VNFI统一提供的虚拟机上，可以虚拟化出以下传统设备的功能：
处理类设备，如：宽带网络网关(Broadband Network Gateway，BNG)、网关GPRS支持节点(Gateway GPRS Support Node，GGSN)/分组数据网关(Packet Data Network Gateway,PDN-GW)、防火墙(Firewall，FW)/NAT、IP安全协议网关(IP security protocol Gateway，IPSEC GW)、DPI、SBC、网络监控设备等。这类设备针对用户或会话实施复杂的包分析、转发、QoS计费、策略、安全等处理。
控制类设备，如：IMS、移动管理实体(Mobile Managenment Entity，MME)、服务GPRS支持节点(Serving GSN，SGSN)、策略和计费规则功能(Policy charging and rules function，PCRF)、LR/归属用户服务器(Home Subscriber Server，HSS)、AAA、CG等。这类设备完成网络的运行控制和用户的接入、服务控制。
其他设备：如：基站、路由器等网络层以下处理设备。
VNF是运营商网络的关键组成部分，在向NFV虚拟化迁移过程中，不仅要保持原有的电信级能力和网络功能特性，而且要发挥云计算中分布式系统优势，实现弹性伸缩、N way冗余等关键云化特性。
除此之外，网络功能虚拟化架构中还可以包括EMS、OSS/BSS等功能模块，不再此处详叙。
需要说明的是，VNF、MANO以及NFVI可以根据网络的不同而进行不同的部署，可以位于同一台物理设备上，例如：MANO与VNF承载在同一台物理设备的不同虚拟机上；也可以位于 多台物理设备上，例如：MANO分布式部署于多台物理设备上或一台物理设备上，一个VNF的虚拟机分布式部署于多台物理设备上或一台物理设备上，对于具体的组网及部署形式，不发明不做限定。
对于NFV基础设施中的COTS服务器，由于CPU对于网络数据处理、复杂算法运算的处理能力相对不足，性能较低，需要使用加速设备来进行业务加速处理，而加速设备可以进行分布式部署，分布式加速资源的部署结构图如图2所示，图2中示出了NFV系统中与加速相关的功能实体。
各功能实体之间通过网络进行通信连接，各功能实体定义如下：
VNF中包括应用程序(Application)和虚拟加速设备(Virtual Acceleration Device)。其中，应用程序用于处理业务；虚拟加速设备为应用程序提供使用加速设备的通信、配置接口。应用程序通过与虚拟加速设备、加速引擎(Acceleration Engine)的通信交互，完成业务加速功能。
MANO中包括基础设施编排(Infrastructure Orchestrator)和基础设施加速设备控制器(Infrastructure Acceleration Device Controller)。其中，基础设施编排负责NFVI的生命周期管理，在基础设施编排的统一主控下，基础设施加速设备控制器负责加速设备(Acceleration Device)的集中管理。
NFVI(NFV基础设施)中包括基础设施加速代理(Infrastructure Acceleration Agent)和加速引擎(Acceleration Engine)。其中，基础设施加速代理分布式部署在每个分散的服务器上(如图所示的服务器A、服务器B)，受基础设施加速设备控制器的整体控制；加速引擎用于实现业务加速功能。
下面对本发明实施中的NFV系统业务加速方法进行详细介绍。
301、可编程包确定实体确定需要加速的目标业务功能；
本发明实施例中的可编程确定实体为图2所示的分布式加速资源的部署结构图中的VNF，或VNF和MANO，用于根据需要加速的具体业务功能确定对应的用于加速的可编程包。
当某个业务功能对应的CPU资源的处理能力不足时，会导致性能较低，需要使用加速设备来进行业务加速处理，可编程包确定实体确定需要加速的目标业务功能。
其中，业务功能是指虚拟化后各种网络功能，例如：BNG、GGSN/PDN-GW、FW/NAT、IPSEC GW、DPI、SBC、网络监控设备功能、IMS、MME、SGSN、PCRF、LR/HSS、AAA、CG等功能。
302、可编程包确定实体获取目标业务功能对应的目标可编程包；
每个业务功能都有相对应的用于加速的可编程包，可编程包用于在加速引擎中运行以对该业务功能进行加速。对应关系例如：网络/DPI业务功能对应的可编程包为可编程包1；网络/IPSEC业务功能对应的可编程包为可编程包2；网络/ACL业务功能对应的可编程包为可编程包3等。
在确定需要加速的目标业务功能后，可编程包确定实体确定该目标业务功能对应的目标可编程包，获取该目标可编程包。
303、可编程包确定实体将目标可编程包发送至网络功能虚拟化基础设施NFVI中的加速引擎；
可编程包确定实体获取目标可编程包之后，将目标可编程包发送给NFVI中的加速引擎。
304、加速引擎运行目标可编程包以加速需要加速的目标业务功能。
加速引擎加载该目标可编程包，运行该可编程包来完成业务加速服务。
本发明实施例中，用于业务加速的可编程包不是预装在加速引擎中的固定可编程包，而是动态的根据当前需要加速的业务功能来确定的可编程包，因而能够动态替换加速引擎的可编程包，满足业务多样性，从而提升NFV系统业务加速功能的可扩展性。
一种可行的实施方式为可编程确定实体VNF和MANO，由MANO控制加速引擎的可编程能力；一种可行的实施方式为可编程确定实体VNF和MANO，由VNF协同MANO控制加速引擎的可编程能力；一种可行的实施例方式为可编程确定实体VNF，由VNF控制加速引擎的可编程能力。
下面对这三种可行的实施方式进行分别说明。
一、可编程确定实体VNF和MANO，由MANO控制加速引擎的可编程能力。
此实施方式对应的业务加速流程示意图如图4所示。
1、MANO管理可编程包和分区情况
由MANO管理加速引擎的可编程包，具体的，由MANO中的基础设施编排管理加速引擎的可编程包。
基础设施编排存储可编程包，并记录需要加速的业务功能和可编程包名称之间的对应关系。加速的业务功能和可编程包名称之间的对应关系的示例如表1所示：
表1
Figure PCTCN2017094756-appb-000001
MANO中存储的业务功能和可编程包名称之间的对应关系可以根据业务的发展以及NFV系统的具体部署而进行更新，例如：可以通过NFV系统操作人员进行人工配置。
进一步，NFVI中每个加速引擎上可以有多个可编程包分区，各分区相互隔离，可以分别动态加载不同的可编程包，以确保各种业务加速能力间无耦合关系，便于进行业务加速能力的独立部署和升级。
可选的，MANO存储有各加速引擎上的分区部署情况，即存储有可编程包与加速引擎分区之间的对应关系。
具体的，由MANO中的基础设施编排收集并记录各服务器的加速引擎上的分区部署情况。 对应关系的示例如表2所示，例如：A服务器有分区0、分区1、分区2三个分区，可编程包1将部署在分区0中，分区1中暂时没有分配可编程包，可编程包2将部署在分区2中；B服务器分了分区3、分区4两个分区，分区3将部署可编程包3，分区4将部署可编程包1。
表2
服务器号 分区号 可编程包名称
A 0 可编程包1
A 1 空
A 2 可编程包2
B 3 可编程包3
B 4 可编程包1
… … …
同样，MANO中存储的各服务器的加速引擎上的分区部署情况可以根据业务的发展以及NFV系统的具体部署而进行更新，例如：可以通过NFV系统操作人员进行人工配置。
2、创建加速网络，建立应用程序、基础设施编排、基础设施加速设备控制器、基础设施加速代理和加速引擎间的通信通道，以便于各实体之间进行通信。
3、VNF中的应用程序确定需要加速的目标业务功能，向MANO中的基础设施编排发送业务加速请求，请求中携带需要加速的目标业务功能，指明需要加速的业务功能。
4、MANO中的基础设施编排根据需要加速的目标业务功能，从存储的表1所示的业务功能和可编程包名称之间的对应关系中确定目标业务功能对应的目标可编程包名称，再从存储的可编程包中获取目标可编程包名称对应的目标可编程包；再根据加速引擎上的分区部署情况(即图2所示的可编程包与加速引擎分区号之间的对应关系)中确定目标可编程包对应的目标分区，目标分区即目标加速引擎分区号。
5、MANO中的基础设施编排通过加速网络向NFVI上的加速引擎传输所述目标可编程包，并携带所述目标分区号，在加速引擎的目标分区进行加载该目标可编程包。
6、加速引擎在指定的所述目标分区运行该目标可编程包来完成目标业务功能的业务加速服务。
在本发明实施例中，由MANO控制加速引擎的可编程能力，不仅可以动态根据需要加速的业务选择可编程包，从而可以满足业务多样性，提升NFV系统业务加速功能的可扩展性；还可以动态根据编程包选择对应的加速引擎分区，加速引擎在不同的分区中动态加载不同的可编程包，以确保各种业务加速能力间无耦合关系，从而可以便于进行业务加速能力的独立部署和升级。
二、可编程确定实体VNF和MANO，由VNF协同MANO一起控制加速引擎的可编程能力。
此实施方式对应的业务加速流程示意图如图5所示。
1、VNF管理可编程包
由VNF管理加速引擎的可编程包，具体的，由VNF中的应用程序管理加速引擎的可编程包。
应用程序存储可编程包，并记录需要加速的业务功能和可编程包名称之间的对应关系。加速的业务功能和可编程包名称之间的对应关系的示例上表1所示。
VNF中存储的业务功能和可编程包名称之间的对应关系可以根据业务的发展以及NFV系统的具体部署而进行更新，例如：可以通过NFV系统操作人员进行人工配置。
2、MANO管理各加速引擎上的可编程包分区部署情况。
与图4所示的实施例相同，由MANO中的基础设施编排收集并记录各服务器的加速引擎上的分区部署情况，即如表2所示的可编程包与加速引擎分区号之间的对应关系。
NFVI中每个加速引擎上可以有多个可编程包分区，各分区相互隔离，可以分别动态加载不同的可编程包，以确保各种业务加速能力间无耦合关系，便于进行业务加速能力的独立部署和升级。
3、创建加速网络，建立应用程序、基础设施编排、基础设施加速设备控制器、基础设施加速代理和加速引擎间的通信通道，以便于各实体之间进行通信。
4、VNF中的应用程序确定需要加速的目标业务功能，从存储的业务功能和可编程包名称之间的对应关系中确定目标业务功能对应的目标可编程包名称，再从存储的可编程包中获取目标可编程包名称对应的目标可编程包，将目标可编程包发送至MANO中的基础设施编排。
5、MANO中的基础设施编排根据加速引擎上的分区部署情况，选择合适的加速引擎分区号。具体是从可编程包与加速引擎分区号之间的对应关系中确定目标可编程包对应的目标分区。
6、MANO中的基础设施编排通过加速网络向加速引擎传输目标可编程包，携带加速引擎目标分区号，在加速引擎的目标分区进行加载该目标可编程包。
7、NFVI中的加速引擎在指定的所述目标分区运行该目标可编程包来完成目标业务功能的业务加速服务。
在本发明实施例中，由VNF协同MANO一起控制加速引擎的可编程能力，不仅可以动态根据需要加速的业务选择可编程包，从而可以满足业务多样性，提升NFV系统业务加速功能的可扩展性；还可以动态根据编程包选择对应的加速引擎分区，加速引擎在不同的分区中动态加载不同的可编程包，以确保各种业务加速能力间无耦合关系，从而可以便于进行业务加速能力的独立部署和升级。
三、可编程确定实体VNF，由VNF控制加速引擎的可编程能力。
此实施方式对应的业务加速流程示意图如图6所示。
1、VNF管理可编程包
由VNF管理加速引擎的可编程包，具体的，由VNF中的应用程序管理加速引擎的可编程包。
应用程序存储可编程包，并记录需要加速的业务功能和可编程包名称之间的对应关系。加速的业务功能和可编程包名称之间的映射关系的示例上表1所示。
VNF中存储的业务功能和可编程包名称之间的对应关系可以根据业务的发展以及NFV系统的具体部署而进行更新，例如：可以通过NFV系统操作人员进行人工配置。
2、创建VNF中的应用程序和NFV中的加速引擎间通信的加速端口(vport)，提供接口给应用程序使用虚拟加速设备。
3、应用程序根据业务需要的加速功能选择对应的可编程包。
VNF中的应用程序确定需要加速的目标业务功能，从存储的业务功能和可编程包名称之间的对应关系中确定目标业务功能对应的目标可编程包名称，再从存储的可编程包中获取目标可编程包名称对应的目标可编程包。
4、VNF中的应用程序通过加速端口(vport)向加速引擎传输可编程包并进行加载。
5、NFV中的加速引擎运行该可编程包来完成目标业务功能的加速服务。
需要说明的是，因为VNF中的应用程序只能感知到虚拟加速设备，无法管理NFV的加速引擎中的实际可编程包分区，所有此方案无法支持多可编程包分区。
在本发明实施例中，由VNF控制加速引擎的可编程能力，可以动态根据需要加速的业务选择可编程包，从而可以满足业务多样性，提升NFV系统业务加速功能的可扩展性。
