不同于传统的三重播放(triple-play)业务,一些新出现的业务,例如业务入云、家庭办公、海外教育、海外游戏、海淘等互联网向用户提供各种应用服务(over the top,OTT)业务,需要运营商保障一定的网络质量。但在现有的宽带接入架构中,所有的因特网业务(包括上述三重播放业务和OTT业务)均混合在同一因特网业务流中进行传输,共用传输路径和带宽,从而导致上述OTT业务没有服务等级协议(service-level agreement,SLA)保障,其中,这里的SLA保障可以理解为运营商提供的网络质量保障。
因此,如何为新出现业务提供SLA保障,是目前亟待解决的问题。
发明内容
本申请实施例提供一种数据传输方法、装置及系统,用于解决现有的宽带接入结构无法为新出现业务提供SLA保障的问题。
为达到上述目的,本申请的实施例采用如下技术方案:
第一方面,提供了一种数据传输方法,该方法包括:光网络终端ONT接收第一数据包;ONT将第一数据包的第一信息与本地或异地存储的第一信息库进行匹配,第一信息库中的第一信息对应的业务在预配置的业务集合内;当第一信息库中不存在第一数据包的第一信息时,ONT将第一数据包通过第一路径发送给第一业务对应的第一服务器,并且在第一业务在预配置的业务集合内的情况下,ONT将第一数据包的第一信息增加至第一信息库中,第一业务为第一数据包对应的业务;当第一信息库中存在第一数据包的第一信息时,ONT将第一数据包通过第二路径发送给第一服务器。基于本申请实施例提供的数据传输方法,当第一信息库中不存在第一数据包的第一信息时,若第一业务在预配置的业务集合内,ONT将第一数据包的第一信息增加至第一信息库,所以ONT后续接收与第一数据包具有相同第一信息的数据包时,该数据包可以通过第二路径传输至服务器,换言之,在预配置的业务集合内的业务,非首包或者在接收首包前第一信息已经在第一信息库中的首包,均可以通过第二路径传输。可以理解的是,若第一业务不在预配置的业务集合内,ONT不将第一数据包的第一信息增加至第一信息库,所以不在预配置的业务集合内的业务,数据包的第一信息不会在第一信息库中,不在预配置的业务集合内的业务的数据均通过第一路径传输。所以,相比于现有方案中将所有业务的数据混合进行传输,本方案可以实现将业务集合内的业务的数据和业务集合外的业务 的数据分开传输,为新出现的业务提供SLA保障。
结合上述第一方面,在一种可能的实现方式中,ONT确定第一数据包对应的第一业务在预配置的业务集合内,包括:ONT根据第一数据包的第二信息确定与第一数据包对应的第一业务在预配置的业务集合内,第二信息用于反映第一数据包对应的第一业务。基于本方案,ONT可以根据数据包的第二信息识别第一数据包对应的第一业务,并确定第一数据包对应的第一业务是否在预配置的业务集合中。
结合上述第一方面,在一种可能的实现方式中,在ONT将第一数据包通过第二路径发送给第一服务器之前,该方法还包括:ONT确定第一数据包对应的业务为第一业务;ONT根据第一业务的标识信息与第二路径的标识信息的对应关系,确定第二路径。由于该方案中的第二路径是业务粒度的,因此可以在业务数据传输时,实现基于业务粒度的路径划分,进一步保障业务的SLA。
结合上述第一方面,在一种可能的实现方式中,第一业务的标识信息与第二路径的标识信息的对应关系存储于ONT中;或者,第一业务的标识信息与第二路径的标识信息的对应关系存储于与ONT连接的云管理平台中。基于本方案,提供了第一业务的标识信息与第二路径的标识信息的对应关系的两种存储方式,可以根据实际需求,选择合适的一种方式进行存储。
结合上述第一方面,在一种可能的实现方式中,在ONT将第一数据包通过第二路径发送给第一服务器之前,该方法还包括:ONT根据第一数据包的第一信息、以及第一数据包的第一信息与第二路径的标识信息的对应关系,确定第二路径。基于该方案,在一个业务唯一对应一个数据包的第一信息的情况下,可以实现基于业务粒度的路径划分,在一个业务可以对应多个数据包的第一信息的情况下,可以实现基于小于业务粒度的路径划分。因此基于该方案,可以进一步保障业务的SLA。
结合上述第一方面,在一种可能的实现方式中,第一数据包的第一信息与第二路径的标识信息的对应关系存储于ONT中;或者,第一数据包的第一信息与第二路径的标识信息的对应关系存储于与ONT连接的云管理平台中。基于本方案,提供了第一数据包的第一信息与第二路径的标识信息的对应关系的两种存储方式,可以根据实际需求,选择合适的一种方式进行存储。
结合上述第一方面,在一种可能的实现方式中,第一信息库本地存储在ONT中,在ONT接收第一数据包之前,该方法还包括:ONT接收来自云管理平台的第一数据包的第一信息;ONT将第一数据包的第一信息存储于第一信息库。基于该方案,可以通过云管理平台,同步更新与云管理平台连接的所有ONT的第一信息库中的第一信息。进一步的,在某一ONT接收到预配置业务集合内业务的首包,但该首包的第一信息之前没有存储在第一信息库的情况下,通过云管理平台的同步更新,若后续其余ONT接收到该业务的数据包,可以直接将数据包通过第二路径传输,节省了其余ONT识别数据包业务的时间和资源。
结合上述第一方面,在一种可能的实现方式中,第一数据包的第一信息包括第一数据包的网际互连协议IP地址、五元组信息或业务流量特征信息。基于本方案,提供了多种第一信息,可以根据实际需求,选择合适的第一信息配置第一信息库。
结合上述第一方面,在一种可能的实现方式中,第二路径为叠加网络隧道。基于本方案,数据包在传输时,可以从叠加网络隧道起点直接传输至叠加网络隧道终点,再由隧道终点传输至第一服务器,可以实现点到点的通信,无需考虑物理基础层网络的物理网络设备的分布,因此相比现有方案基于物理基础层网络进行传输,本方案可以保障端到端的业务质量。
结合上述第一方面,在一种可能的实现方式中,第一信息库本地存储在ONT中;或者, 第一信息库异地存储在与ONT连接的云管理平台中。基于本方案,提供了第一信息库的两种存储方式,可以根据实际需求,选择合适的一种方式进行存储。
结合上述第一方面,在一种可能的实现方式中,业务集合包括:增值业务或者互联网向用户提供各种应用服务OTT业务。基于本方案,可以将增值业务或者OTT业务与其余业务分开传输,实现对增值业务或OTT业务的SLA保障。
第二方面,提供了一种光网络终端ONT用于实现上述方法。该ONT具有实现上述第一方面所述的方法的功能。该功能可以通过硬件实现,也可以通过硬件执行相应的软件实现。该硬件或软件包括一个或多个与上述功能相对应的模块。如:该第一设备可以包括:收发模块和处理模块。收发模块,用于接收第一数据包;处理模块,用于将第一数据包的第一信息与本地或异地存储的第一信息库进行匹配,第一信息库中的第一信息对应的业务在预配置的业务集合内;当第一信息库中不存在第一数据包的第一信息时,处理模块,还用于通过收发模块将第一数据包通过第一路径发送给第一业务对应的第一服务器,并且在处理模块确定第一业务在预配置的业务集合内的情况下,处理模块,还用于将第一数据包的第一信息增加至第一信息库中,第一业务为第一数据包对应的业务;当第一信息库中存在第一数据包的第一信息时,处理模块,用于通过收发模块将第一数据包通过第二路径发送给第一服务器。
结合上述第二方面,在一种可能的实现方式中,处理模块确定第一数据包对应的第一业务在预配置的业务集合内,包括:处理模块,用于根据第一数据包的第二信息确定与第一数据包对应的第一业务在预配置的业务集合内,第二信息用于反映第一数据包对应的第一业务。
结合上述第二方面,在一种可能的实现方式中,在处理模块通过收发模块将第一数据包通过第二路径发送给第一服务器之前,处理模块,还用于确定第一数据包对应的业务为第一业务;处理模块,还用于根据第一业务的标识信息与第二路径的标识信息的对应关系,确定第二路径。
结合上述第二方面,在一种可能的实现方式中,ONT还包括存储模块,第一业务的标识信息与第二路径的标识信息的对应关系存储于存储模块中;或者,第一业务的标识信息与第二路径的标识信息的对应关系存储于与ONT连接的云管理平台中。
结合上述第二方面,在一种可能的实现方式中,在处理模块通过收发模块将第一数据包通过第二路径发送给第一服务器之前,处理模块,还用于根据第一数据包的第一信息、以及第一数据包的第一信息与第二路径的标识信息的对应关系,确定第二路径。

结合上述第二方面,在一种可能的实现方式中,第一数据包的第一信息包括第一数据包的网际互连协议IP地址、五元组信息或业务流量特征信息。

具体实施方式
详细描述本申请实施例之前,为了便于理解本申请实施例的技术方案,首先给出本申请相关技术名词的简要介绍如下:
1、OTT(over the top)业务:
OTT业务是指互联网公司越过运营商,发展基于开放互联网的各种视频及数据服务业务。目前,典型的OTT业务有互联网电视业务、业务入云、家庭办公、海外教育、海外游戏、海淘等。
2、物理基础层网络(underlay network)、叠加网络(overlay network)、隧道(tunneling)以及叠加网络隧道:
物理基础层网络是由不同物理网络设备之间的连接构成的底层网络,它负责跨网络传送数据包。在数据中心环境中,物理基础层网络的作用是提供从任何物理网络设备(服务器、存储设备、路由器或交换机)到任何其他物理网络设备的网际互连协议(internet protocol,IP)地址连接。
叠加网络指的是一种建立在物理基础层网络之上的虚拟的计算机网络,其大体框架是对物理基础层网络不进行大规模修改的条件下,实现应用在物理基础层网络上的承载。例如, 以物理基础层网络包括因特网为例,则很多对等网络(peer to peer,P2P)是叠加网络,因为它们运行在因特网的上面。其中,叠加网络是由多个结点以及不同结点之间的连接关系构成的,数据通过不同结点之间的连接,从一个结点传输至另一个结点。需要说明的是,叠加网络中的结点并非实际的物理网络设备,但叠加网络的结点可能在物理基础层网络对应一个物理网络设备。类似的,叠加网络中不同结点之间的连接同样是逻辑概念,并非实际的物理链接,它很可能是多条物理链路的集合,是用特定策略虚拟出来的链接。
隧道技术是一种通过使用互联网络的基础设施在网络之间传递数据的方式。使用隧道传递的数据(或负载)可以是不同协议的数据包(也可以称之为数据帧),隧道协议将其它协议的数据包重新封装后通过隧道发送。其中,重新封装后获得的新的数据包头提供路由信息,以便通过互联网传递被封装的负载数据。隧道技术通过点对点的通信协议,能够使来自不同信息源的网络业务在同一个基础设施中通过相同的隧道进行传输。
叠加网络隧道是在叠加网络中传输数据的隧道。其中,叠加网络隧道的起点和终点均可以对应叠加网络中的结点。因此,叠加网络隧道可以使数据传输时不依赖物理基础层网络的物理网络设备的分布,从一个物理网络设备到另一个物理网络设备来进行传输,而是跨越物理网络设备,直接从叠加网络隧道的起点传输至叠加网络隧道的终点。
3、三重播放(triple-play)业务:
三重播放业务,是一种融合了话音、数据和视频业务的捆绑业务模式。三重播放业务提供三种服务,包括:高速因特网、电视(请求的视频和一般的广播)和通过单个宽带连接的电话服务。现有的宽带接入基础架构中,业务规划是基于三重播放业务粗粒度,在物理基础层网络进行上行服务质量(quality of service,QOS)调度。
4、五元组
五元组通常指数据包的源IP地址,源端口,目的IP地址,目的端口,和传输层协议这五个量组成的一个集合。
图1为现有的宽带接入基础架构的示意图。如图1所示,现有的宽带接入基础架构主要分为三个部分:家庭网关(residential gateway,RG)、接入网络(access network)和汇聚网络(broadband network)。其中,光网络终端(optical network terminal,ONT)或者光网络单元(optical network unit,ONU)是接入网络中为家庭用户提供网络的设备。当家庭用户的终端设备请求接入业务时,业务流的数据包从终端设备通过RG传输至ONT后,通过光分配网(optical distribution network,ODN),光线路终端(optical line terminal,OLT)传输至以太汇聚设备(eth agg)。进一步的,一种传输方式下,数据包由以太汇聚设备传输至宽带网络网关(broadband network gateway,BNG),由BNG根据数据包的目的IP地址等表征数据包目的地址的信息为数据包分配目的地址,例如网络服务提供商(network server provider,NSP)或应用服务提供商(application service provider,ASP)的IP地址,并通过二层隧道服务器(layer 2 tunneling server,L2TS),根据二层隧道协议(layer 2 tunneling protocol,L2TP)将数据包传输至目的地址,或者,根据数据包的IP地址进行QOS调度(对应图1中的IP-QOS)将数据包传输至目的地址。另一种传输方式下,数据包由以太汇聚设备专线传输至目的地址或BNG。
随着通信技术的发展,不同于传统的三重播放业务,一些新出现的业务,例如业务入云、家庭办公、海外教育、海外游戏、海淘等OTT业务,需要运营商保障一定的网络质量。但在现有的宽带接入架构中,所有的因特网业务(包括上述三重播放业务和OTT业务)均混合在同一因特网业务流中进行传输,共用传输路径和带宽,从而导致上述OTT业务没有SLA保障。 因此,如何为新出现业务提供SLA保障,是目前亟待解决的问题。
基于此,本申请提出数据传输方法、装置及系统,以解决现有的业务数据传输方案无法为新出现业务提供SLA保障的问题。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述。其中,在本申请的描述中,除非另有说明,“/”表示前后关联的对象是一种“或”的关系,例如,A/B可以表示A或B;本申请中的“和/或”仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况,其中A,B可以是单数或者复数。并且,在本申请的描述中,除非另有说明,“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达,是指的这些项中的任意组合,包括单项(个)或复数项(个)的任意组合。例如,a,b,或c中的至少一项(个),可以表示:a,b,c,a-b,a-c,b-c,或a-b-c,其中a,b,c可以是单个,也可以是多个。另外,为了便于清楚描述本申请实施例的技术方案,在本申请的实施例中,采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定,并且“第一”、“第二”等字样也并不限定一定不同。同时,在本申请实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念,便于理解。
图2为应用本申请实施例提供的数据传输方法的通信系统20的架构示意图。如图2所示,该通信系统20包括ONT30和第一服务器40。ONT30,用于接收第一数据包。ON30,还用于将第一数据包的第一信息与本地或异地存储的第一信息库进行匹配,第一信息库中的第一信息对应的业务在预配置的业务集合内;当第一信息库中不存在第一数据包的第一信息时,ONT30将第一数据包通过第一路径发送给第一业务对应的第一服务器,并且在ONT30确定第一业务在预配置的业务集合内的情况下,ONT30将第一数据包的第一信息增加至第一信息库中,第一业务为第一数据包对应的业务;当第一信息库中存在第一数据包的第一信息时,ONT30将第一数据包通过第二路径发送给第一服务器40。第一服务器40,用于接收第一数据包。该方案的具体实现以及技术效果将在后续方法实施例中详细描述,在此不予赘述。
应理解,图2仅是示例性的给出应用本申请实施例提供的数据传输方法的通信系统20的架构示意图,并不限定该通信系统20仅包括一个ONT30或者一个第一服务器40。换言之,该通信系统20可以包括多个ONT30或者多个第一服务器40,在此统一说明,以下不再赘述。
可选的,如图2所示,该通信系统20还可以包括云管理平台50。该云管理平台50与ONT30之间可以直接通信,也可以通过其他设备的转发进行通信,本申请实施例对此不作具体限定。其中,云管理平台50,用于向ONT30发送第一数据包的第一信息。ONT30,用于接收来自云管理平台50的第一数据包的第一信息,并将第一数据包的第一信息存储于第一信息库。
可选的,本申请实施例中的ONT30、或者第一服务器40或云管理平台50的相关功能可以由一个设备实现,也可以由多个设备共同实现,还可以是由一个设备内的一个或多个功能模块实现,本申请实施例对此不作具体限定。可以理解的是,上述功能既可以是硬件设备中的网络元件,也可以是在专用硬件上运行的软件功能,或者是硬件与软件的结合,或者是平台(例如,云平台)上实例化的虚拟化功能。

存储器303可以是具有存储功能的装置。例如可以是只读存储器(read-only memory,ROM)或可存储静态信息和指令的其他类型的静态存储设备,随机存取存储器(random access memory,RAM)或者可存储信息和指令的其他类型的动态存储设备,也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory,EEPROM)、只读光盘(compact disc read-only memory,CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质,但不限于此。存储器可以是独立存在,通过通信线路302与处理器相连接。存储器也可以和处理器集成在一起。
其中,存储器303用于存储执行本申请方案的计算机执行指令,并由处理器301来控制执行。处理器301用于执行存储器303中存储的计算机执行指令,从而实现本申请实施例中提供的数据传输方法。
或者,可选的,本申请实施例中,也可以是处理器301执行本申请下述实施例提供的数据传输方法中的处理相关的功能,通信接口304负责与其他设备或通信网络通信,本申请实施例对此不作具体限定。
可选的,本申请实施例中的计算机执行指令也可以称之为应用程序代码,本申请实施例对此不作具体限定。
在具体实现中,作为一种实施例,处理器301可以包括一个或多个CPU,例如图3中的CPU0和CPU1。
在具体实现中,作为一种实施例,通信装置300可以包括多个处理器,例如图3中的处理器301和处理器307。这些处理器中的每一个可以是一个单核(single-core)处理器,也可以是一个多核(multi-core)处理器。这里的处理器可以包括但不限于以下至少一种:中央处理单元(central processing unit,CPU)、微处理器、数字信号处理器(DSP)、微控制器(microcontroller unit,MCU)、或人工智能处理器等各类运行软件的计算设备,每种计算设备可包括一个或多个用于执行软件指令以进行运算或处理的核。

下面将结合图1至图3,对本申请实施例提供的数据传输方法进行具体阐述。
如图4所示,为本申请实施例提供的一种数据传输方法,该数据传输方法包括如下步骤S401-S404:
S401、ONT接收来自终端设备的第一数据包。
S402、ONT将第一数据包的第一信息与本地或异地存储的第一信息库进行匹配,第一信息库中的第一信息对应的业务在预配置的业务集合内。
S403、当第一信息库中不存在第一数据包的第一信息时,ONT将第一数据包通过第一路径发送给第一业务对应的第一服务器,并且在ONT确定第一业务在预配置的业务集合内的情况下,ONT将第一数据包的第一信息增加至第一信息库中,第一业务为第一数据包对应的业务。
S404、当第一信息库中存在第一数据包的第一信息时,ONT将第一数据包通过第二路径发送给第一服务器。
下面对步骤S401-S404展开进行描述。
需要说明的是,本申请实施例中,业务的首包为该业务对应的业务流的第一个数据包,业务的非首包为该业务对应的业务流的第一个数据包之后的数据包。在此统一说明,以下不再赘述。
需要说明的是,本申请实施例中,ONT还可以称为ONT网关。在此统一说明,以下不再赘述。
对于上述步骤S401:
本申请实施例中,ONT接收来自终端设备的第一数据包之后,可以确定第一数据包的第一信息。可选的,本申请实施例中,第一数据包的第一信息包括第一数据包的目的IP地址、五元组信息或业务流量特征信息等信息。
对于上述步骤S402:
一种可能的实现方式中,第一信息库可以本地存储在ONT中。该方式中,ONT可以通过查询本地的第一信息库,将第一数据包的第一信息与第一信息库中存储的第一信息进行匹配。
或者,另一种可能的实现方式中,第一信息库可以异地存储在与ONT连接的云管理平台中,所述连接指网络连接。该方式中,ONT可以通过与ONT连接的云管理平台,查询存储在云管理平台的第一信息库,将第一数据包的第一信息与第一信息库中存储的第一信息与进行匹配。
需要说明的是,本申请实施例中,第一信息库本地存储和异地存储可以共存。例如,ONT和云管理平台分别存储有一个第一信息库。可选的,ONT和云管理平台可以通过交互信息,更新或删除自身存储的第一信息库中的第一信息,以保持各个第一信息库中第一信息的一致。
本申请实施例中,第一信息库中的第一信息有对应的业务,且对应的业务在预配置的业务集合内。以下进行具体阐述。
本申请实施例中,第一信息与业务间存在对应关系。对于同一业务,可能有多条业务流,对于同一业务流,数据包(包括首包和非首包)的第一信息是相同的。不同业务流的数据包 的第一信息可能不同,但均对应同一业务。例如,数据包的第一信息是目的IP地址,游戏A业务有2条业务流,其中业务流1的所有数据包的目的IP地址均是游戏A的服务器1所在的IP地址,业务流2的所有数据包的目的IP地址均是游戏A的服务器2所在的IP地址。所以,业务流1或业务流2的首包和非首包的第一信息是相同的,业务流1和业务流2分别对应的数据包的第一信息是不同的,但业务流1或业务流2的数据包的第一信息均对应游戏A业务。换言之,本申请实施例中,一个业务可以唯一对应一个数据包的第一信息,也可以一个业务对应多个数据包的第一信息,本申请实施例对此不做具体限定。
可选的,本申请实施例中,第一数据包的第一信息与第一数据包对应的第一业务间的对应关系,可以本地存储在ONT或异地存储在与ONT连接的云管理平台中。
本申请实施例中,预配置的业务集合,可以理解为需要通过独立路径传输的业务的集合,或者说,是需要保障SLA的业务的集合。
需要说明的是,本申请实施例中,可以根据用户需求,基于不同的业务粒度配置业务集合。例如,可以按照粗业务粒度配置业务集合,所有游戏业务和线上购物业务均配置在预配置的业务集合中,网络视频业务不在预配置的业务集合中。还可以按照细业务粒度配置业务集合,游戏业务中,游戏A业务和游戏C业务配置在预配置的业务集合中,游戏B业务不在预配置的业务集合中。本申请实施例对此不做限制。
可选的,本申请实施例中,预配置的业务集合可以包括增值业务或者OTT业务。其中,增值业务可以理解为业务价值较高的业务,或者对业务质量要求较高的业务。例如游戏、线上办公等要求时延低,不卡顿,用户付费意愿较高的业务。OTT业务可参考上文的介绍,在此不再赘述。
可选的,本申请实施例中,预配置的业务集合可以本地存储在ONT中。该方式中,ONT可以通过查询本地的业务集合来选择是否将第一数据包的第一信息增加至第一信息库。
或者,可选的,本申请实施例中,预配置的业务集合可以异地存储在与ONT连接的云管理平台中。该方式中,ONT可以通过与ONT连接的云管理平台,查询存储在云管理平台的业务集合来选择是否将第一数据包的第一信息增加至第一信息库。
可选的,本申请实施例中,可以根据实际需求,对预配置的业务集合中的业务进行更新或删除。
进一步的,本申请实施例中,在ONT将第一数据包的第一信息与第一信息库中的第一信息进行匹配之后,根据匹配情况的不同,ONT执行步骤S403或步骤S404。
对于上述步骤S403:
一种可能的实现方式中,本申请实施例中,由于第一服务器与第一业务对应,这种对应关系可以预配置,因此ONT可以根据数据包对应的第一业务确定接收第一数据包的第一服务器。例如,ONT确定接收的第一数据包对应游戏业务,ONT根据预配置的游戏业务对应的第一服务器的IP地址,将第一数据包传输至第一服务器。ONT如何确定第一数据包对应的第一业务,在下文进行具体介绍。
另一种可能的实现方式中,ONT可以根据第一数据包的目的IP地址,确定接收第一数据包的第一服务器。其中,第一服务器的IP地址与第一数据包的目的IP地址相同。
可选的,本申请实施例中,第一路径可以为现有的宽带接入架构中,数据包从ONT传输至第一服务器的传输路径。比如,结合图1,第一路径为物理基础层网络中的ONT—OLT—以太汇聚设备—BNG—第一服务器。其中,BNG确定第一服务器的方式可以参考上文介绍的ONT如何确定第一服务器的方式,在此不再赘述。该方案中,根据现有的物理网络架构,数据包 在物理基础层网络,通过许多物理网络设备传输到第一服务器。
在步骤S403中,对于通过第一路径传输的第一数据包,若ONT确定与第一数据包对应的第一业务在预配置的业务集合内,ONT将第一数据包的第一信息增加至第一信息库中。换言之,若ONT确定第一数据包对应的第一业务不在预配置的业务集合内,ONT不将第一数据包的第一信息增加至第一信息库中。基于本方案,若ONT接收到预配置的业务集合内的业务的首包,但首包的第一信息之前没有存储进第一信息库,ONT可以将首包的第一信息增加至第一信息库,以使后续ONT接收该业务的非首包时,可以在第一信息库中匹配到非首包的第一信息。另一方面,因为若第一数据包对应的第一业务不在预配置的业务集合内,ONT不将第一数据包的第一信息增加至第一信息库中,所以不在预配置的业务集合内的业务的数据均通过第一路径传输。
可选的,ONT确定第一数据包对应的第一业务是否在预配置的业务集合内,包括:
ONT根据第一数据包的第二信息确定第一数据包对应的第一业务是否在预配置的业务集合内,第二信息用于反映第一数据包对应的第一业务。基于本方案,ONT可以根据数据包的第二信息识别第一数据包对应的第一业务,并确定第一数据包对应的第一业务是否在预配置的业务集合中。
可选的,本申请实施例中,第一数据包的第二信息包括第一数据包的目的IP地址、五元组信息或业务流量特征信息等信息。
需要说明的是,本申请实施例中,第一数据包的第一信息与第二数据包的第二信息可以是同一信息,也可以是不同的信息。换言之,ONT用于确定第一数据包传输路径的信息,与ONT用于确定第一数据包对应的第一业务的信息,可以是相同的信息,也可以是不同的信息,本申请实施例对此不作限定。
对于上述步骤S404:
可以理解的是,因为第一信息库中的第一信息对应的业务在预配置的业务集合内,如果ONT可以在第一信息库中匹配到第一数据包的第一信息,或者说第一信息库中存在第一数据包的第一信息,说明第一数据包对应的第一业务在预配置的业务集合内。该情况下,ONT将第一数据包通过第二路径发送给第一服务器,ONT如何确定第一服务器可以参考上述步骤S403,在此不再赘述。
由上文介绍可知,现有的技术方案中,数据传输和调度业务基于物理基础层网络,需要经过许多物理网络设备,无法保障端对端(从终端设备到目的服务器)的业务质量,尤其业务跨域或跨网时,物理基础层网络的传输路径上的物理网络设备的数量和类型都更多。为了保障一些特定业务的业务质量,现有技术还提供了一种方案:将特定业务通过光纤专线传输,不与其他业务的业务流混合传输。但是,光纤专线的成本很高,很难实现大规模推广。
因此,可选的,本申请实施例中,第二路径可以为叠加网络隧道。该方案中,叠加网络隧道的起点在物理基础网络层对应ONT,第一数据包从叠加网络隧道的起点(叠加网络的结点1)出发,通过叠加网络隧道,在叠加网络层直接传输至叠加网络隧道的终点(叠加网络的结点2),由叠加网络隧道的终点将第一数据包传输至第一服务器。示例性的,如图5所示,在物理基础层网络,叠加网络隧道终点对应的物理网络设备可以为隧道网关,隧道网关与BNG连接,由隧道网关为第一数据包分配目的地址并传输至第一服务器。示例性的,隧道网关可以为云网关。该方案中,数据包在传输时,从叠加网络隧道起点直接传输至叠加网络隧道终点,再由隧道终点传输至第一服务器,可以实现点到点的通信,无需考虑物理基础层网络的物理网络设备的分布,因此相比现有方案基于物理基础层网络进行传输,本方案可以保障端 到端的业务质量,且另一方面,叠加网络隧道相比光纤传输成本低,可以规模复制。
基于本申请实施例提供的数据传输方法,当第一信息库中不存在第一数据包的第一信息时,第一数据包通过第一路径传输,当第一信息库中存在第一数据包的第一信息时,第一数据包通过第二路径传输。且当第一信息库中不存在第一数据包的第一信息时,若第一业务在预配置的业务集合内,ONT将第一数据包的第一信息增加至第一信息库,所以ONT后续接收与第一数据包具有相同第一信息的数据包时,该数据包可以通过第二路径传输至服务器,换言之,在预配置的业务集合内的业务,非首包或者在接收首包前第一信息已经在第一信息库中的首包,均可以通过第二路径传输。可以理解的是,若第一业务不在预配置的业务集合内,ONT不将第一数据包的第一信息增加至第一信息库,所以不在预配置的业务集合内的业务,数据包的第一信息不会在第一信息库中,不在预配置的业务集合内的业务的数据均通过第一路径传输。所以,相比于现有方案中将所有业务的数据混合进行传输,本方案可以实现将业务集合内的业务的数据和业务集合外的业务的数据分开传输,为新出现的业务提供SLA保障。
其中,上述步骤S401至S404中ONT的动作可以由图3所示的通信装置300中的处理器301调用存储器303中存储的应用程序代码以指令该通信装置执行;本实施例对此不作任何限制。上述步骤S401至S404中第一服务器的动作可以由图3所示的通信装置300中的处理器301调用存储器303中存储的应用程序代码以指令该通信装置执行;本实施例对此不作任何限制。
可选的,对于上述步骤S404,在ONT将第一数据包通过第二路径发送给第一服务器之前,一种可能的实现方式中,本申请实施例提供的数据传输方法还包括:ONT确定第一数据包对应的业务为第一业务,ONT根据第一数据包对应的第一业务的标识信息与第二路径的标识信息的对应关系,确定第二路径。其中,ONT确定第一数据包对应的第一业务可参考上文对步骤S403的介绍在此不再赘述。
即,本方案中的第二路径是业务粒度的。例如,游戏业务的标识信息为A,网购业务的标识信息为B,线上购物的标识信息为C。第二路径有3条,标识信息分别为1、2、3,其中标识信息A与标识信息1对应,标识信息B与标识信息2对应,标识信息C与标识信息3对应。ONT确定第一数据包对应的业务为游戏业务后,根据上述对应关系,选择与标识信息A对应的标识信息为1的第二路径发送第一数据包。由于该方案中的第二路径是业务粒度的,因此可以在业务数据传输时,实现基于业务粒度的路径划分,进一步保障业务的SLA。
可选的,对于上述步骤S404,在ONT将第一数据包通过第二路径发送给第一服务器之前,另一种可能的实现方式中,本申请实施例提供的数据传输方法还包括:ONT根据第一数据包的第一信息、以及第一数据包的第一信息与第二路径的标识信息的对应关系,确定第二路径。
即,本方案直接根据第一数据包的第一信息与第二路径的标识信息的对应关系确定第二路径。例如,第二路径有2条,标识信息分别为a、b,其中,标识信息a与数据包的第一信息中的第一信息1对应,标识信息b与数据包的第一信息中的第一信息2对应,则当ONT确定第一数据包的第一信息为第一信息1之后,ONT根据上述对应关系,选择标识信息为a的第二路径发送第一数据包;当ONT确定第一数据包的第一信息为第一信息2之后,ONT根据上述对应关系,选择标识信息为b的第二路径发送第一数据包。可选的,第一信息1和第一信息2可以是同一业务的不同数据包的第一信息,也可以是不同业务的数据包的第一信息。基于该方案,在一个业务唯一对应一个数据包的第一信息的情况下,可以实现基于业务粒度的路径划分,在一个业务可以对应多个数据包的第一信 息的情况下,可以实现基于小于业务粒度的路径划分。因此基于该方案,可以进一步保障业务的SLA。
可选的,上述第一业务的标识信息与第二路径的标识信息的关系或第一数据包的第一信息与第二路径的标识信息的对应关系,可以以表格的形式存储或者可以以其它方式存储,本申请实施例对此不做具体限定。
可选的,上述第一业务的标识信息与第二路径的标识信息的对应关系、或第一数据包的第一信息与第二路径的标识信息的对应关系可以本地存储在ONT中。该方式中,ONT可以通过查询本地的上述对应关系来确定第二路径。
或者,可选的,本申请实施例中,上述对应关系可以异地存储于在与ONT连接的云管理平台中。该方式中,ONT可以通过与ONT连接的云管理平台,查询存储在云管理平台上的上述对应关系来确定第二路径。
可选的,当第一信息库本地存储在ONT时,在ONT接收第一数据包,本申请实施例提供的数据传输方法还包括:ONT接收来自云管理平台的第一数据包的第一信息,并将接收的第一数据包的第一信息存储于第一信息库。
该方案中,云管理平台可以向ONT发送第一数据包的第一信息,以使ONT接收第一数据包的第一信息,并同步更新存储于ONT本地的第一信息库。可选的,云管理平台发送的第一信息,可以来自其他ONT。示例性的,第一ONT接收第一数据包并获取第一数据包的第一信息,第一ONT在确定存储于第一ONT本地的第一信息库中不存在第一数据包的第一信息后,第一ONT将第一数据包的第一信息增加至第一ONT本地的第一信息库,并将第一数据包的第一信息传输至云管理平台,云管理平台接收到第一数据包的第一信息后,向与云管理平台连接的其他ONT广播第一数据包的第一信息,其他ONT接收到来自云管理平台的第一数据包的第一信息后,将该第一信息存储于其他ONT本地的第一信息库。进而,其他ONT后续接收到与第一数据包的第一信息相同的数据包(后续简称为第一业务的数据包)后,可以在其他ONT本地的第一信息库匹配到第一业务的数据包的第一信息,并将第一业务的数据包通过第二路径传输到第一业务对应的第一服务器。可选的,本方案中,云管理平台也可以存储第一信息库,即上述示例中,第一ONT向云管理平台发送第一数据包的第一信息时,云管理平台可以将接收的第一数据包的第一信息增加至存储于云管理平台的第一信息库,并将第一数据包的第一信息广播给其他ONT。
基于该方案,可以通过云管理平台,同步更新与云管理平台连接的所有ONT的第一信息库中的第一信息。进一步的,在某一ONT接收到预配置业务集合内业务的首包,但该首包的第一信息之前没有存储在第一信息库的情况下,通过云管理平台的同步更新,若后续其余ONT接收到该业务的数据包,可以直接将数据包通过第二路径传输,节省了其余ONT识别数据包业务的时间和资源。
为了方便理解,以下将结合一个具体的示例,对本申请实施例提供的数据传输法进行介绍。该示例中,假设终端设备为手机,数据包的第一信息为数据包的目的IP地址,数据包的第二信息为业务流量特征信息。如图6所示,为该示例的流程示意图,包括如下步骤:
S601、用户A在手机1上玩游戏A,手机1将游戏A业务流的首包:数据包1,和数据包1之后的非首包:数据包2发送至ONT1。
S602、ONT1接收到数据包1之后,ONT1中的IP地址匹配模块,将数据包1的目的IP地址与ONT1本地的IP地址库中的IP地址进行匹配。
其中,由于ONT1之前没有接入过游戏A的业务流,因此IP地址库中不存在数据包1的 目的IP地址,因此ONT1中的IP地址匹配模块在本地IP地址库中匹配不到数据包1的目的IP地址,或者说ONT1中的第一信息库中不存在数据包1的第一信息。
S603、ONT1中的IP地址匹配模块将数据包1传输至ONT1中的首包应用识别模块,ONT1中的首包应用识别模块根据数据包1的业务流量特征信息,识别出数据包1对应的业务为游戏A业务。假设游戏A业务是预配置的业务集合中的业务,则将数据包1传输至ONT1中的自动学习IP模块。
S604、ONT1中的自动学习IP模块学习到数据包1的目的IP地址为预配置的业务集合中的游戏A业务对应的第一信息,自动学习IP模块将数据包1的目的IP地址增加至ONT1本地的IP地址库。同时,ONT1中的自动学习IP模块还将数据包1的目的IP地址上报给云管理平台。云管理平台将接收的来自ONT1的数据包1的目的IP地址,存储至云管理平台的IP地址库。
S605、ONT1中的自动IP学习模块根据数据包1的目的IP地址,将数据包1通过第一路径发送给游戏A业务的服务器1,服务器1的IP地址与数据包1的目的IP地址相同。其中,第一路径的相关描述可参考图4所述的实施例,在此不再赘述。
S606、云管理平台的IP地址分发模块将数据包1的目的IP地址广播至与云管理平台连接的其他ONT(如附图中的ONT2和ONT3)。与云管理平台连接的其他ONT接收数据包1的目的IP地址之后,在本地IP地址库中存储数据包1的目的IP地址。
S607、ONT1接收到数据包2之后,ONT1中的IP地址匹配模块,将数据包2的目的IP地址与ONT1本地的IP地址库中的IP地址进行匹配。
其中,由于在上述步骤S604中,ONT1中的自动学习IP模块将数据包1的目的IP地址增加至本地的IP地址库中,且数据包1与数据包2的目的IP地址相同,因此ONT1中的IP地址匹配模块可以在本地IP地址库中匹配到数据包2的目的IP地址,或者说,ONT1中的第一信息库中存在数据包2的第一信息。
S608、ONT1中的IP地址匹配模块将数据包2通过配置的家庭专线隧道1在叠加网络层传输至云网关1。其中,家庭专线隧道1是叠加网络隧道。
S609、云网关根据数据包2的目的IP地址将数据包2传输至游戏A业务的服务器1。
S610、用户B在手机2上玩游戏A,手机2将游戏A业务流的首包:数据包3发送至ONT2。其中,数据包3的目的IP地址与数据包1的目的IP地址相同,均为服务器1。
S611、ONT2接收到数据包3之后,ONT2中的IP地址匹配模块,将数据包3的目的IP地址与ONT3本地的IP地址库中的IP地址进行匹配。
其中,由于在上述步骤S606中,ONT2接收来自云管理平台的数据包1的目的IP地址并将其存入ONT2本地的IP地址库,所以ONT2中的IP地址匹配模块可以在本地IP地址库中匹配到数据包3的目的IP地址,或者说,ONT2中的第一信息库中存在数据包3的第一信息。
S612、ONT2中的IP地址匹配模块将数据包3通过配置的家庭专线隧道2在叠加网络层传输至云网关2。其中,家庭专线隧道2是叠加网络隧道。
S613、云网关2根据数据包3的目的IP地址将数据包3传输至游戏A业务的服务器1。
