业务处理方法及装置、存储介质
相关申请的交叉引用
本发明基于申请号为201610482668.3、申请日为2016年6月27日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的内容在此引入本发明作为参考。
技术领域
本发明涉及通信技术，具体而言，涉及一种业务处理方法及装置、存储介质。
背景技术
宽带接入服务器(Broadband Remote Access Server，简称为BRAS)是一种面向宽带网络应用的接入网关。它是宽带接入网和骨干网之间的桥梁，提供基本的接入手段和宽带接入网的管理功能。它位于网络的边缘，提供宽带接入服务、实现多种业务的汇聚与转发，能满足不同用户对传输容量和带宽利用率的要求，因此是宽带用户接入的核心设备。BRAS对于接入的用户首先进行认证，认证通过允许用户访问宽带网络，认证失败拒绝用户访问宽带网络。
网络功能虚拟化(Network Function Virtualization，简称为NFV)是通过基于行业标准的服务器、存储和网络设备取代私有专用网元设备。带来两个好处：1、标准设备成本低廉，节省投资成本；2、开放应用程序编程接口(Application Programming Interface，简称为API)，提供灵活网络功能扩展。
BRAS功能的虚拟化(BRAS NFV)是该领域的热点。宽带化战略是国 家重要的长期战略计划，投入成本巨大，使用NFV可以节省投资成本。BRAS作为宽带业务的控制层，需要部署丰富的业务，而且具备灵活的扩展性。传统的BRAS设备添加新业务，需要设备厂商开发调试，周期较长，影响新业务的开展。通过NFV提供的开放接口，新业务的开发不再依赖于设备厂商，部署时间更短。通过BRAS功能的虚拟化，可以带来节省资本投入和提高收益的好处。
BRAS功能的虚拟化的一种实现方法：控制面和转发面分离，控制层放在通用服务器上，并提供API，转发面接收控制面下发的转发策略和利用转发策略进行流量转发。在转发面，宏观上看成是个转发池，用户流量在转发池进行转发，微观上，转发池是由多个转发实例组成。流量进行转发池后，具体是通过转发实例进行转发。其中，转发实例可以是物理转发设备，也可以是软件实现的软件转发设备。
BRAS网络功能虚拟化(NFV)后，架构和处理流程和传统设备有显著的不同。协议流量和数据流量首先经过转发池，转发池对流量的处理直接影响整个BRAS的性能。
相关技术中，转发池对流量的处理方式有两种。一种处理方式：首先在转发池中某一个转发实例中进行处理，当这个转发实例容量和性能达到一定的阈值后切换到另一个转发实例，这种轮询的处理方式，对于新生用户的上线和流量转发性能和一个转发实例的性能相当，不能充分发挥转发池的性能优势。另一种处理方式：按照先到先处理的方式进行一定程度上的负载分担。但是这种方式没有充分考虑转发实例的具体能力，转发实例的能力有强有弱，先到先处理的方式，可能只选择了一个非能力最优和分担最低的转发实例，性能不能做到最优。
因此，相关技术中转发池对流量的处理方式无法保证转发池对流量的处理性能最优。

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，本发明中的实施例及实施例中的特征可以相互组合。
需要说明的是，本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本发明实施例所提供的方法实施例可以在终端、计算机终端或者类似的运算装置中执行。以运行在终端上为例，图1是本发明实施例的一种业务处理方法的终端的硬件结构框图。如图1所示，终端10可以包括一个或多个(图中仅示出一个)处理器102(处理器102可以包括但不限于微处理器MCU或可编程逻辑器件FPGA等的处理装置)、用于存储数据的存储器104、以及用于通信功能的传输装置106。本领域普通技术人员可以理解，图1所示的结构仅为示意，其并不对上述电子装置的结构造成限定。例如，终端10还可包括比图1中所示更多或者更少的组件，或者具有与图1所示不同的配置。
存储器104可用于存储应用软件的软件程序以及模块，如本发明实施例中的业务处理方法对应的程序指令/模块，处理器102通过运行存储在存储器104内的软件程序以及模块，从而执行各种功能应用以及数据处理，即实现上述的方法。存储器104可包括高速随机存储器，还可包括非易失性存储器，如一个或者多个磁性存储装置、闪存、或者其他非易失性固态存储器。在一些实例中，存储器104可进一步包括相对于处理器102远程设置的存储器，这些远程存储器可以通过网络连接至终端10。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。
传输装置106用于经由一个网络接收或者发送数据。上述的网络具体 实例可包括终端10的通信供应商提供的无线网络。在一个实例中，传输装置106包括一个网络适配器(Network Interface Controller，NIC)，其可通过基站与其他网络设备相连从而可与互联网进行通讯。在一个实例中，传输装置106可以为射频(Radio Frequency，RF)模块，其用于通过无线方式与互联网进行通讯。
在本实施例中提供了一种运行于终端的业务处理方法，图2是根据本发明实施例的业务处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，获取用于转发业务的转发池中的每个转发实例的处理能力和/或转发实例的当前负载情况，其中，转发池由多个转发实例组成；
步骤S204，根据获取的处理能力和/或当前负载情况，从转发池中选择用于转发业务的选定转发实例；
步骤S206，根据确定的选定转发实例对业务进行转发处理。
通过上述步骤，由于根据获取的处理能力和/或当前负载情况，从转发池中选择用于转发业务的选定转发实例，使得对业务进行转发处理的转发实例是处理能力最优、负载最低的转发实例，因此，可以解决相关技术中转发池对流量的处理方式无法保证转发池对流量的处理性能最优的问题，达到提高工作效率的效果。
可选地，转发池中的所有转发实例可以由控制面控制，并由控制面把这些转发实例组成逻辑上的转发池，如图3所示。可选地，上述转发实例的能力可以分为协议流量处理的能力和数据流量处理的能力；转发实例的负载可以分为协议流量处理的负载和数据流量处理的负载，如图4所示。其中，转发实例的能力可以包括多种，例如，可以包括以下至少之一：CPU能力，存储能力，带宽能力，转发能力，用户数限制等；负载可以包括多种，例如，可以包括以下至少之一：CPU利用率，存储使用量，带宽消耗，当前转发速率，当前用户数等。
可选地，可以通过以下方式至少之一，获取用于转发业务的转发池中的每个转发实例的处理能力和/或转发实例的当前负载情况：通过向转发实例发送用于请求获取转发实例的处理能力和/或当前负载情况的请求消息，以及接收转发实例反馈的携带有转发实例的处理能力和/或当前负载情况的响应消息的方式，获取用于转发业务的转发池中的每个转发实例的处理能力和转发实例的当前负载情况；通过周期性的接收转发实例发送的用于通知转发实例的处理能力和/或当前负载情况的通知消息的方式，获取用于转发业务的转发池中的每个转发实例的处理能力和转发实例的当前负载情况。可选地，对于转发实例的当前负载情况为统一控制分配的负载(如带宽)的情况下，也可以通过本地获取。
例如，对于转发实例的处理能力，可以在初始状态(即未开始进行转发业务)获取，如图5所示，在初始状态发送处理能力请求，转发实例收到处理能力请求并获取处理能力后生成处理能力响应上报，根据该处理能力响应，保存收到的处理能力。其中，上报该处理能力的通道，可以使用已有的协议如开放流(Openflow)协议或者自定义私有协议。
又例如，对于转发实例的当前负载情况为统一控制分配的负载(如带宽)的情况下，统一控制分配的负载可以通过本地获取，如图6所示，统一控制分配负载更新操作可以由控制面管理：步骤602：用户通过协议交互上线，步骤604：用户上线后，分配资源后，更新控制面本地管理的负载。
又例如，对于转发实例的当前负载情况为转发实例的实时流量负载的情况下，转发实例的实时流量负载需要定时获取，定时获取方式可以包括两种：拉方式和推方式。拉方式：定时向转发实例发送负载请求，转发实例获取当前负载组成响应获取转发实例的实时流量负载。以控制面获取转发实例的实时流量负载为例对拉方式进行说明，如图7所示，该过程包括：步骤702：负载请求超时定时器超时，步骤704：超时后发送负载请求，到 转发实例请求获取转发实例的当前负载情况，步骤706：转发实例收到负载请求后，获取当前负载情况组成负载响应，发送到控制面，步骤708：控制面收到负载响应后，更新本地的转发实例实时负载。推方式：根据转发实例定时发送的携带负载的通知信息获取转发实例的实时流量负载。
以控制面获取转发实例的实时流量负载为例对推方式进行说明，如图8所示，该过程包括：步骤802：转发实例负载上报定时器超时，步骤804：获取转发实例当前负载情况组成负载上报通知消息，通知控制面，步骤806：控制面收到通知，获取转发实例当前负载情况，更新本地保存的负载情况。
可选地，根据获取的处理能力和/或当前负载情况，从转发池中选择用于转发业务的选定转发实例包括：根据获取的处理能力和当前负载情况，确定每个转发实例的剩余能力；根据确定的每个转发池的剩余能力，从转发池中选择用于转发业务的选定转发实例。通过上述步骤，可以快速的从转发池中选择出剩余能力最优的选定转发实例。
例如，以控制面获取多个转发实例的能力、负载，以及确定剩余能力为例对上述实施例进行说明，如图9所示，该过程包括：
步骤902：如图6所示的方法获取、发现转发实例1的处理能力，
步骤904：如图6所示的方法获取、发现转发实例2的处理能力，
步骤906：如图6所示的方法获取、发现转发实例3的处理能力，
步骤908：分别把各个转发实例的处理能力保存在控制面，
步骤910：分配资源后，更新在控制面保存的转发实例的负载情况，计算剩余能力，
步骤912：“拉”方式获取转发实例1、2、3的负载情况，
步骤914：获取转发实例的负载情况后，更新在控制面保存的转发实例的负载情况，计算剩余能力，
步骤916：“推”方式获取转发实例1、2、3的负载情况，
步骤918：获取转发实例的负载后，更新在控制面保存的转发实例的负载情况，计算剩余能力。
可选地，根据获取的处理能力和当前负载情况，确定每个转发实例的剩余能力包括：根据每个转发实例的处理能力和每个转发实例的当前负载情况，确定每个转发实例的初始剩余能力；根据初始剩余能力，每个转发实例的预设权重，以及归一化函数，确定每个转发实例的剩余能力。例如，可以通过以下算法确定剩余能力：
Figure PCTCN2017088128-appb-000001
Ci表示第i个转发实例的处理能力值，Li表示第i个转发实例的当前负载值，Ci-Li表示第i个转发实例的剩余能力值，函数fi()表示第i个转发实例的剩余能力值的归一化函数，表示第i个转发实例的剩余能力值从绝对值转换成和其他转发实例的剩余能力值的相对值，提供统一比较的基础。Bi表示第i个转发实例的剩余能力的权重，通过调节权重可以动态调整第i个转发实例的剩余能力的在整个转发池剩余能力中的比重，从而可以调节第i个转发实例的剩余能力的重要程度。该权重作为策略的重要参数，可以由用户调节。
Figure PCTCN2017088128-appb-000002
表示1到n个剩余能力值相加，相加后数值大的表示剩余能力强，每次策略选择转发实例时，选择剩余能力数值大的转发实例。
通过上述步骤，可以通过调整每个转发实例的预设权重，动态调整第每个转发实例的剩余能力的在整个转发池剩余能力中的比重，从而可以调节每个转发实例的剩余能力的重要程度。
可选地，转发实例包括：协议流量转发实例和数据流量转发实例。
需要说明的是，上述实施例的执行主体可以为控制面，可以应用于转发实例和控制面组成的系统。为了方便理解本发明实施例，下面分别以控制面选择协议流量处理选定转发实例和数据流量转发选定转发实例为例对本发明实施例进行说明，以及以应用于转发实例和控制面组成的系统为例 进行说明。
图10是根据本发明实施例的控制面选择协议流量处理选定转发实例和数据流量转发选定转发实例的流程图，如图10所示，该过程包括：
步骤S1002，转发实例收到接入协议报文，上报到控制面。用户通过接入协议接入BRAS，所述的接入协议可以为动态主机配置协议(Dynamic Host Configuration Protocol，简称为DHCP)、DHCPv6、以太网上的点对点协议(PPP over Ethernet，简称为PPPoE)、地址解析协议(Address Resolution Protocol，简称为ARP)、邻居发现协议(Neighbor Discover，简称为ND)等。转发池对于用户可达，用户接入协议报文可以达到转发池中任一转发实例，由于大多接入协议为广播报文，所以每个转发实例都会收到协议报文，然后转发实例把协议报文上送到控制面，以便控制面知晓每个转发实例均与用户成功接通，其中，所述上送的协议可以为开放流(OPENFLOW)协议也可以为自定义的私有协议。
步骤S1004，控制面根据协议处理负载分担策略选择协议处理选定转发实例。
步骤S1006，控制面完成认证、授权后，生成用户表，然后根据每个转发实例的负载情况选择流量转发选定转发实例。根据负载分担策略选择流量转发选定转发实例后，控制面下发用户接入用户表到流量转发选定转发实例，所述的下发用户表可以通过Openflow协议或者自定义的私有协议，其他非选定接入实例不下发用户表，则用户转发流量只通过流量转发选定转发实例转发。

图12是根据本发明实施例的系统进行协议流量处理负载分担和数据流量转发负载分担各个组件之间的交互示意图，如图12所示，该过程包括：

为充分理解本发明实施例，以DHCP接入为例对本发明实施例进行消息说明。如图13组网，用户通过交换机互连到转发池的每个转发实例，用户到每个转发实例二层转发可达。控制面控制转发池，转发池中有三个转发实例，控制面到转发池的每个转发实例三层转发可达。能力和负载简单起见只考虑一种类型：带宽。能力表示总带宽，负载表示消耗的带宽，剩余能力为剩余的带宽。
图14是根据本发明实施例的DHCP接入业务处理交互示意图，如图14所示，DHCP接入完成后，控制面按照策略，在剩余能力强的转发实例上进行协议流量处理和数据流量处理。该过程包括：
步骤1402：转发实例1上报能力，协议流量处理总带宽为100兆(M)，数据流量处理总带宽为10吉(G)；
步骤1404：转发实例2上报能力，协议流量处理总带宽为120M，数据流量处理总带宽为8G；
步骤1406：转发实例3上报能力，协议流量处理总带宽为90M，数据流量处理总带宽为9G；
步骤1408：由于此时各个转发实例的负载为0，所以各个转发实例的 剩余能力为各个转发实例的协议流量处理和数据流量处理总带宽；
步骤14010：用户发送DHCP发现(Discover)协议报文，申请网际协议(IP，Internet Protocol)地址；用户发送的DHCP Discover协议报文到达交换机，因为该报文为广播报文，所以进行复制；
步骤14012：复制的一个DHCP Discover协议报文转发到转发实例1；
步骤14014：复制的一个DHCP Discover协议报文转发到转发实例2；
步骤14016：复制的一个DHCP Discover协议报文转发到转发实例3；
步骤14018：转发实例1把DHCP Discover报文上送到控制面；
步骤14020：转发实例2把DHCP Discover报文上送到控制面；
步骤14022：转发实例3把DHCP Discover报文上送到控制面；
步骤14024：控制面根据各个转发实例的协议流量处理剩余能力选择协议流量处理选定转发实例，由于转发实例2的协议流量处理剩余能力最强，所以选择转发实例2为协议流量处理选定转发实例；
步骤14026：进行认证，本实例采用的认证方式为DHCP选项(option)认证；认证不通过，流程结束；认证通过，然后进行授权，授权信息中包含分配给用户的IP地址和协议流量处理带宽10M和数据流量处理带宽为200M，分配带宽后，更新转发实例2的协议流量处理负载为10M，更新转发实例2的剩余能力为120M-10M；
步骤14028：认证通过并授权后，构造DHCP提供(Offer)协议报文，该协议报文中包含分配给用户的IP地址，发送到协议流量处理选定转发实例——转发实例2；
步骤14030：转发实例2生效协议流量处理带宽，并把DHCP Offer协议报文转发到交换机；
步骤14032：交换机把DHCP Offer协议报文转发到用户；
步骤14034：用户构造DHCP请求(Request)协议报文并发送到交换 机；
步骤14036：交换机把DHCP Request协议报文转发到转发池中的转发实例2；
步骤14038：转发实例2把DHCP Request协议报文上送到控制面；
步骤14040：控制面收到DHCP Request协议报文，生成用户表，控制面根据各个转发实例的数据流量处理剩余能力选择协议流量处理选定转发实例，由于转发实例1的数据流量处理剩余能力最强，所以选择转发实例1为数据流量处理选定转发实例；更新转发实例1的数据流量处理负载为200M，更新转发实例1的剩余数据流量处理剩余能力为10G-200M；
步骤14042：控制面下发用户表到转发实例1，转发实例1生效数据流量处理带宽；
步骤14044：控制面构造DHCP响应(ACK)协议报文并发送到转发实例1；
步骤14046：转发实例2把DHCP ACK协议报文转发到交换机；
步骤14048：交换机把DHCP ACK协议报文转发到用户，用户申请到IP地址，流程结束。
