Specifically, it includes the following steps: generating and configuring first configuration information for the first edge node, generating and configuring second configuration information for the first relay node, and generating and configuring third configuration information for the second edge node.
  • the first edge node may be a source node
  • the second edge node may be a destination node

  • acquiring a data packet may include two cases: one case is that the cancellation module obtains two or more of the same sequence number Data packets, then one of them can be selected for output; the other case is that because the data packet is lost during transmission, the elimination module only receives one data packet of a certain sequence number, then the data can be The package is sent out.

  • the first packet received can be output; if the elimination module receives two or more packets at the same time Data packets with the same sequence number can be output from any one of them.
  • a flag bit can be set for each data packet in the elimination module, and a flag bit identifies whether a data packet of a serial number is output. For example, if the flag bit of data packet 1 is 1, it means that the data packet with sequence number 1 has been output; if the flag bit of data packet 1 is 0, it means that the data packet with sequence number 1 has not been output. In this way, if the elimination module receives a data packet with a certain serial number, you can query the corresponding flag bit of the serial number packet.
  • the corresponding flag bit is 0, it means that the elimination module has not sent a data packet of this serial number before, so you can send The data packet; if the corresponding flag bit is 1, it means that the elimination module has sent the data packet of the serial number before, so the data packet can be deleted. If the elimination module receives multiple data packets with the same sequence number at the same time, and the corresponding flag bit of the sequence number data packet is 0, one of the multiple data packets with the same sequence number can be selected for output. If the elimination module receives multiple data packets with the same sequence number at the same time, and the corresponding flag bit of the sequence number data packet is 1, it is possible to delete multiple data packets with the same sequence number received at the same time.

Description

一种业务流处理方法及装置
本申请要求于2018年10月31日提交中国专利局、申请号为CN 201811290209.0、发明名称为“一种业务流处理的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请实施例涉及通信技术领域，尤其涉及一种业务流处理方法及装置。
背景技术
随着通信网络的发展，业务流的传输不仅要考虑可达性，还要考虑可靠性。目前，传输业务流的一种高可靠性网络架构通常可以包括边缘节点(edge node)和中继节点(relay node)。其中，边缘节点连接到业务流的源节点和/或目的节点，并从业务流的源节点接收业务流和/或发送业务流到业务流的目的节点；而中继节点为业务流从源节点传输到目的节点的过程中所经过的节点。从源节点到目的节点之间的路径由一条或多条路径段构成，中继节点用于将相邻的路径段连接在一起，以保证业务流的可达。从源节点到目的节点的路径可以有多条，从而起到业务保护的作用。业务流同时在多条路径中传输，只要有一条路径没有发生故障，目的节点就可以成功接收到业务流，从而保证了业务流传输的可靠性。
所以，业务流传输的关键在于如何对各个节点进行配置，以实现业务流的传输和保护。
发明内容
本申请实施例提供了一种业务流处理方法及装置，用于实现业务流的传输和保护。
第一方面，本申请实施例提供了一种业务流处理方法，该方法可以应用于控制器，控制器可以独立于以下各个节点，也可以部署于其中一个节点，例如第一边缘节点。具体包括如下步骤：为第一边缘节点生成并配置第一配置信息，为第一中继节点生成并配置第二配置信息，以及为第二边缘节点生成并配置第三配置信息。第一边缘节点可以是源节点，第二边缘节点可以是目的节点，第一中继节点在第一边缘节点和第二边缘节点之间的链路上。其中，第一配置信息用于复制第一边缘节点接收到的业务流所包括的数据包，并向第一中继节点输出复制所获得的第一数据包以及向第二中继节点输出复制所获得的第二数据包。第二配置信息用于第一中继节点复制第一数据包，并向第二中继节点输出复制所获得的第三数据包，以及从复制所获得的第四数据包和来自第二中继节点的第五数据包中获取数据包并输出。第三配置信息用于从来自第一中继节点的数据包和来自第二中继节点的数据包中获取数据包。第二中继节点位于第一边缘节点经第一中继节点到第二边缘节点的链路之外。本申请实施例通过为第一边缘节点生成并配置第一配置信息，为第一中继节点生成并配置第二配置信息，以及为第二边缘节点生成并配置第三配置信息，实现对业务流的保护和输出。
其中，第一边缘节点可以通过接入电路(attachment circuit，AC)接收来自第一用户边缘(customer edge，CE)节点的业务流，业务流所包括的数据包可以是一个或多个。为了区分业务流包括的多个数据包，第一边缘节点可以为每个数据包分配一个序号，数据包序号的连续性体现数据包内容的连续性。例如数据包1表示业务流中的第一个数据包(首 个数据包)；数据包2表示业务流中的第二个数据包；数据包3表示业务流的第三个数据包等。
在实际应用中，执行上述复制步骤的功能模块可以是复制模块，执行上述获取数据包步骤的功能模块可以是消除模块。
第一边缘节点的复制模块对业务流中的数据包进行复制时，可以按照序号由小到大或由大到小的顺序逐个进行复制。第一中继节点或下文其他中继节点的复制模块在对接收到的数据包复制时，可以按照数据包的接收顺序逐个对每个数据包进行复制。数据包被复制之后，不仅内容相同，序号也不变。
对于第一中继节点、第二边缘节点或下文中其他中继节点的消除模块而言，获取数据包可以包括两种情况：一种情况是消除模块获取到两个或两个以上序号相同的数据包，那么可以从中选择其中一个数据包输出；另外一种情况是，由于数据包在传输的过程中发生丢包，导致消除模块只接收到某个序号的一个数据包，那么可以将该数据包发送出去。对于前一种情况，如果消除模块先后接收到两个或两个以上的序号相同的数据包，则可以将最先接收到的一个数据包输出；如果消除模块同时接收到两个或两个以上序号相同的数据包，那么可以从中任选一个输出。
在具体实现时，可以在消除模块中为每个数据包都分别设置一个标志位，一个标志位标识一个序号的数据包是否被输出。例如，若数据包1的标志位为1，则表示序号为1的数据包已被输出；若数据包1的标志位为0，则表示序号为1的数据包没有被输出。这样，如果消除模块接收到某个序号的数据包，可以查询该序号数据包对应的标志位，如果对应的标志位为0，说明该消除模块之前没有发送过该序号的数据包，所以可以发送该数据包；如果对应的标志位为1，说明该消除模块之前发送过该序号的数据包，所以可以删除该数据包。如果消除模块同时接收到序号相同的多个数据包，且该序号数据包对应的标志位为0，则可从序号相同的多个数据包中任选其中一个输出。如果消除模块同时接收到序号相同的多个数据包，且该序号数据包对应的标志位为1，则可以将同时接收到的序号相同的多个数据包删除。
可选的，方法还包括：为第二中继节点生成并配置第四配置信息，第四配置信息用于复制来自第一边缘节点的第二数据包，向第一中继节点输出复制所获得的第五数据包，以及从复制所获得的第六数据包和来自第一中继节点的第三数据包中获取先接收到的数据包并输出。也就是说，作为其中一种可能的实现方式，可以为第二中继节点配置复制模块和消除模块，以实现对业务流的保护和传输。
为了能够实现对业务流的传输和保护，各个节点的配置信息可以包括对应模块的入口信息和出口信息。入口信息可以例如为入口段信息和/或入口端口信息。入口段信息至少包括入口段标识，可选的，还可以包括入口段互联网协议(internet protocol，IP)地址和/或入口段标签。其中入口段IP地址包括入口段的始节点IP地址和终节点IP地址。入口端口信息可以包括入口端口标识。出口信息可以例如为出口段信息和/或出口端口信息。出口段信息至少包括出口段标识，可选的，还可以包括出口段IP地址和/或出口段标签。其中出口段IP地址包括出口段的始节点IP地址和终节点IP地址。出口端口信息可以包括出口端口标识。其中，段是指节点之间的链路和节点内部的连接。段标识为段的标识，段具有方向，例如从第一边缘节点到第一中继节点之间的段和从第一中继节点到第一边缘节点之间的段不是同一个段，相应的，二者对应的段标识也不同。在本申请实施例中，段标识可以 是32位无符号整数。段标签是指与段标识对应的标签，可以是范围为[16,1048575]内的整数。段IP地址包括段的始节点的IP地址和终节点的IP地址，始节点IP地址和终节点IP地址可以是32位的IPv4地址或者是128位的IPv6地址。

具体实施方式
在本申请实施例中，业务流是指某个业务的数据流。业务流包括数据包。数据包对于以太网技术来说就是以太帧，对于互联网协议(internet protocol，IP)技术来说就是IP分组，对于多协议标签交换(multi-protocol label switching，MPLS)技术来说就是MPLS分组。在目前的高可靠性网络传输技术中，没有给出如何为传输业务流的各个节点进行配置的技术方案，以实现对业务流的传输和保护。
例如，确定性网络(deterministic networking，Detnet)技术是一种为实时应用业务流提供极低丢包率和有界延时的技术。Detnet架构包括两种不同类型的节点，即边缘节点和中继节点。其中，边缘节点为Detnet业务层的源节点和/或目的节点，而中继节点为从源节点到目的节点之间的Detnet路径上的节点。从源节点到目的节点之间的网络路径由路径段构成，中继节点用于将相邻的路径段连接在一起，并且提供业务保护功能。
Detnet架构定义了节点中可以实现的功能，包括分组复制功能(packet replication function，PRF)、分组消除功能(packet elimination function，PEF)和分组排序功能(packet ordering function，POF)，它们统一称为PREOF。其中，分组复制功能是指将分组进行复制并通过一个或多个段(segment)分别转发到一个或多个下一跳节点。分组消除功能是指从来自一个或多个段的分组中消除冗余的分组，从而避免网络上过多的分组洪泛或者将重复的分组发送到Detnet域外。分组排序功能是指将乱序的分组进行重新排序。
虽然Detnet架构定义了节点中可以实现的功能，但是并未规定在具体某个节点中配置哪个或哪些功能来实现对业务流的传输和保护。
为了解决上述技术问题，本申请实施例提供了一种业务流处理方法、装置及设备，目的在于实现业务流的传输和保护。
下面结合附图来介绍本申请实施例提供的业务流处理方法、装置及设备。
参见图1，本申请实施例提供的业务流处理方法包括如下步骤：
S101：获取多个节点的配置信息。
在本申请实施例中，多个节点包括边缘节点和中继节点，其中边缘节点包括第一边缘节点和第二边缘节点。边缘节点可以通过接入电路与用户边缘节点连接。例如第一边缘节点与第一用户边缘节点连接，第二边缘节点与第二用户边缘节点连接。第一用户边缘节点将业务流传输给第一边缘节点，第一边缘节点可以将业务流适配封装为一个个的数据包，以便第一边缘节点进行传输。
第一边缘节点和第二边缘节点之间有至少两条路径，每条路径上都有至少一个中继节点。数据包从第一边缘节点开始同时经过至少两条路径到达第二边缘节点，只要有一条路径没有发生故障，第二边缘节点就可以接收到数据包，从而保证了数据传输的可靠性。第二边缘节点接收到数据包之后可以将不重复的数据包重新解封装并组装为业务流的形式， 并将业务流发送给第二用户边缘节点。
参见图2，该图为其中一种可能的多个节点的架构示意图。在该图中，包括第一边缘节点(Edge A)、第二边缘节点(Edge B)和两个中继节点，即第一中继节点(Relay C)和第二中继节点(Relay D)。其中，Edge A、Relay C和Relay D之间相互连接，Relay C和Relay D均与Edge B连接。
Edge A与CE1通过AC1连接，以使Edge A能够接收来自CE1的业务流，并将业务流适配封装为一个一个数据包；Edge B与CE2通过AC2连接，以使Edge B能够将接收到的数据包组装为业务流传输给CE2。
在图2中，数据包从Edge A到Edge B可以一共有四条路径，它们分别是：
路径1：Edge A→Relay C→Edge B；
路径2：Edge A→Relay C→Relay D→Edge B；
路径3：Edge A→Relay D→Edge B；
路径4：Edge A→Relay D→Relay C→Edge B。
CE1发送的业务流可以从Edge A经过这四条路径中传输到Edge B，从而到达CE2。只要有任何一条路径没有发生故障，就可以保证CE2接收到业务流。为了确保Edge A的数据包可以从四条路径经过，可以为第一边缘节点、第二边缘节点、第一中继节点和第二中继节点生成对应的配置信息，以配置相应的功能模块。
对于Edge A而言，可以为其生成第一配置信息，第一配置信息用于复制接收到的业务流所包括的数据包，并向Relay C输出复制所获得的第一数据包以及向Relay D输出复制所获得的第二数据包。也就是说，第一配置信息用于Edge A配置复制模块，该复制模块能够使得Edge A将接收到的来自CE1的业务流所包括的数据包进行复制，得到第一数据包和第二数据包，并向Relay C发送第一数据包，向Relay D发送第二数据包。其中，接收到的业务流所包括的数据包可以是一个，也可以是多个。
对于Relay C而言，可以为其生成第二配置信息，第二配置信息用于复制第一数据包，并向Relay D输出复制所获得的第三数据包，以及从复制所获得的第四数据包和来自所述Relay D的数据包中获取数据包并向Edge B发送。可选的，获取的数据包可以是Relay C从复制所获得的第四数据包和来自Relay D的数据包中先接收到的数据包。也就是说，第二配置信息用于Relay C配置复制模块和消除模块。其中，复制模块能够使得Relay C将接收到的第一数据包进行复制，得到第三数据包和第四数据包，并向Relay D发送第三数据包；消除模块能够使得Relay C从第四数据包和来自Relay D的数据包(也就是下文提到的第五数据包)中获取先接收到的数据包并向Edge B发送。如果Relay C先接收到第四数据包，则向Edge B发送第四数据包；如果Relay C先接收到第五数据包，则向Edge B发送第五数据包。
对于Relay D而言，可以为其生成第四配置信息。其中，第四配置信息用于复制来自于所述Edge A的第二数据包，并向Relay C输出复制所获得的第五数据包，以及从复制所获得的第六数据包和来自所述Relay C的第三数据包中获取数据包并向Edge B发送。可选的，获取的数据包可以是从复制所获得的第六数据包和来自所述Relay C的第三数据包中获取先接收到的数据包。也就是说，第四配置信息用于Relay D配置复制模块和消除模块。其中，Relay D的复制模块能够使得Relay D将接收到的第二数据包进行复制，得到第五数据包和第六数据包，并向Relay C发送第五数据包。Relay D的消除模块能够使得Relay D 从复制所获得的第六数据包和来自所述Relay C的第三数据包中获取先接收到的数据包并向Edge B发送，后接收到的可以被删除。在本申请实施例中，Relay D可以按照数据包的接收顺序对数据包进行获取，即获取首先接收到的数据包。如果Relay D先接收到第六数据包，后接收到第三数据包，那么就向Edge B发送第六数据包；如果Relay D先接收到第三数据包，后接收到第六数据包，那么就向Edge B发送第三数据包。
对于Edge B而言，为了避免网络上过多的洪泛或者将重复的发送到域外，可以为其生成第三配置信息，第三配置信息用于从接收到的来自Relay C的数据包和来自所述Relay D的数据包中获取数据包并输出。可选的，获取的数据包可以是从接收到的来自Relay C的数据包和来自所述Relay D的数据包中获取先接收到的数据包。也就是说，第三配置信息用于Edge B配置消除模块，该模块能够使得Edge B从接收到的来自所述Relay C的数据包和来自所述Relay D的数据包中获取先接收到的数据包并可以向CE2发送。例如，如果来自所述Relay C的数据包为第四数据包，来自Relay D的数据包为第六数据包，且Edge B先接收到第四数据包，后接收到第六数据包，那么可以删除第六数据包，并向CE2发送第四数据包。
基于以上分析，参见图3(a)，该图为图2所示实施例中多节点的一种可能的功能模块架构示意图。在图3(a)中，Edge A可以配置复制模块(以下简称Rep)101，Relay C可以配置Rep 102和消除模块(以下简称Elm)103，Relay D可以配置Rep 104和Elm 105，Edge B可以配置Elm 106。其中，Rep 101分别与Rep 102以及Rep 104连接，Rep 102分别与Elm 103和Elm 105连接，Rep 104分别与Elm 103和Elm 105连接，Elm 103和Elm 105均与Elm 106连接。
Rep 101用于将接收到的数据包进行复制，得到第一数据包和第二数据包，并向Rep102发送第一数据包，向Rep 104发送第二数据包。Rep 102对第一数据包进行复制，得到第三数据包和第四数据包，并向Elm 105发送第三数据包，向Elm 103发送第四数据包。Rep 104对第二数据包进行复制，得到第五数据包和第六数据包，并向Elm 103发送第五数据包，向Elm 105发送第六数据包。Elm 103从第四数据包和第五数据包中获取其中先接收到的数据包并向Elm 106发送。Elm 105从第三数据包和第六数据包中获取其中先接收到的数据包并向Elm 106发送。Elm 106从来自Elm 103的数据包和Elm 105的数据包中获取其中先接收到的数据包并向CE2发送。
需要说明的是，如前文所提，业务流可以包括一个或多个数据包。为了识别不同的数据包，可以采用序号来标识业务流的各个数据包。具体的，Edge A可以按照由小到大或由大到小的顺序来标识一条业务流中的数据包，数据包序号的连续性体现数据包内容的连续性。例如数据包1表示业务流中的第一个数据包(首个数据包)；数据包2表示业务流中的第二个数据包；数据包3表示业务流的第三个数据包等。在Edge A的复制模块对业务流中的数据包进行复制时，可以按照序号由小到大或由大到小的顺序逐个进行复制。例如，Edge A对业务流包括的数据包1、数据包2和数据包3进行复制，即先对数据包1进行复制，再对数据包2进行复制，最后对数据包3进行复制。数据包被复制之后，不仅内容相同，序号也不变。例如，数据包1被进行复制之后所获得的两个或两个以上的数据包均为数据包1，数据包2被进行复制之后所获得的两个或两个以上的数据包均为数据包2。所以，如果业务流中包括多个数据包，那么复制得到的第一数据包和第二数据包也均分别包括多个。例如，如果业务流中包括数据包1、数据包2和数据包3，那么复制得到的第一 数据包也包括数据包1、数据包2和数据包3，复制得到的第二数据包中也包括数据包1、数据包2和数据包3。
在本申请实施例中，中继节点的复制模块在对数据包进行复制时，可以按照数据包的接收顺序逐个对每个数据包进行复制。例如，Relay C的复制模块按照先后顺序接收到数据包1、数据包2和数据包3，则可以按照该顺序对各个数据包进行复制。如果数据包在传输的过程中发生乱序，那么仍然可以按照接收的先后顺序进行复制。例如Relay C的复制模块按照先后顺序接收到数据包1、数据包3和数据包2，那么可以按照该顺序对各个数据包进行复制。
对于消除模块而言，有两种情况。一种情况是消除模块获取到两个或两个以上序号相同的数据包，可以从中选择一个数据包发送出去。另外一种情况是，由于数据包在传输的过程中发生丢包，导致消除模块只接收到某个序号的一个数据包，那么可以将该数据包发送出去。对于前一种情况，如果消除模块先后接收到两个或两个以上的序号相同的数据包，则可以将最先接收到的一个数据包输出；如果消除模块同时接收到两个或两个以上序号相同的数据包，那么可以从中任选一个输出。
例如，第四数据包包括数据包1，第五数据包也包括数据包1，那么Relay C的消除模块选择先接收到的数据包1发送出去。如果这两个数据包1同时接收到，那么可以任选其中一个数据包1输出。
具体实现时，可以在消除模块中为每个数据包都分别设置一个标志位，一个标志位标识一个序号的数据包是否被发送。例如，若数据包1的标志位为1，则表示序号为1的数据包已被发送；若数据包1的标志位为0，则表示序号为1的数据包没有被发送。
这样，如果消除模块接收到某个序号的数据包，可以查询该序号数据包对应的标志位，如果对应的标志位为0，说明该消除模块之前没有发送过该序号的数据包，所以可以发送该数据包；如果对应的标志位为1，说明该消除模块之前发送过该序号的数据包，所以可以删除该数据包。
为了能够让数据包按照如图3(a)所示的流向传输，各个节点的配置信息可以包括对应模块的入口信息和出口信息。
入口信息可以例如为入口段信息和/或入口端口信息。入口段信息至少包括入口段标识，可选的，还可以包括入口段IP地址和/或入口段标签。其中入口段IP地址包括入口段的始节点IP地址和终节点IP地址。入口端口信息可以包括入口端口标识。
出口信息可以例如为出口段信息和/或出口端口信息。出口段信息至少包括出口段标识，可选的，还可以包括出口段IP地址和/或出口段标签。其中出口段IP地址包括出口段的始节点IP地址和终节点IP地址。出口端口信息可以包括出口端口标识。
在本申请实施例中，入口段标识和出口段标识可以是32位无符号整数，始节点IP地址和终节点IP地址可以是32位的IPv4地址或者是128位的IPv6地址，本文仅以IPv4为例加以说明，入口段标签和出口段标签可以是范围为[16,1048575]内的整数。
在介绍各个节点的入口段信息和出口段信息之前，首先介绍一下段和与段相关的概念。
在本申请实施例中，节点之间的链路和节点内部的连接可以称为段，段标识为段的标识。段具有方向，例如从Edge A到Relay C之间的段和从Relay C到Edge A之间的段不是同一个段，相应的，二者对应的段标识也不同。
以图2和图3(a)为例，从Edge A到Relay C之间的段的段标识为“1001”，从Relay C到Edge B之间的段的段标识为“1002”，从Relay C到Relay D之间的段的段标识为“1003”，从Relay D到Relay C之间的段的段标识为“1004”，从Edge A到Relay D之间的段的段标识为“1005”，从Relay D到Edge B之间的段的段标识为“1006”。上述段标识“1001”至“1006”均为节点之间的段的标识。节点内部的段标识例如包括Relay C中从Rep102到Elm 103之间的段的段标识“2001”，以及Relay D中从Rep 104到Elm 105之间的段的段标识“2002”。
在本申请实施例中，段标签是指与段标识对应的标签。以图2和图3(a)为例，从Edge A到Relay C之间的段的段标签为“501”，从Relay C到Edge B之间的段的段标签为“502”，从Relay C到Relay D之间的段的段标签为“503”，从Relay D到Relay C之间的段的段标签为“504”，从Edge A到Relay D之间的段的段标签为“505”，从Relay D到Edge B之间的段的段标签为“506”。上述段标签“501”至“506”均为节点之间的段标签。节点内部的段标签例如包括Relay C中从Rep 102到Elm 103之间的段的段标签“20”，以及Relay D中从Rep 104到Elm 105之间的段的段标签“21”。
此外，各个节点还可以具有IP地址。以图2和图3(a)为例，Edge A的IP地址为10.0.0.1，Edge B的IP地址为10.0.0.2，Relay C的IP地址为10.0.0.3，Relay D的IP地址为10.0.0.4。
那么，Edge A的配置信息，即第一配置信息，也可以视为Rep 101的配置信息，可以包括：出口段标识“1001”和出口段标识“1005”。可选的，第一配置信息还可以包括：与出口段标识“1001”对应的出口段IP地址10.0.0.1(始节点IP地址)和10.0.0.3(终节点IP地址)，以及与出口段标识“1005”对应的出口段IP地址10.0.0.1(始节点IP地址)和10.0.0.4(终节点IP地址)。和/或，第一配置信息还可以包括：与出口段标识“1001”对应的段标签“501”和与出口段标识“1005”对应的段标签“505”。
Relay C的配置信息，即第二配置信息，包括Rep 102的配置信息和Elm 103的配置信息。
其中，Rep 102的配置信息包括：入口段标识“1001”以及出口段标识“2001”和出口段标识“1003”。可选的，Rep 102的配置信息还可以包括：与入口段标识“1001”对应的段IP地址10.0.0.1(始节点IP地址)和10.0.0.3(终节点IP地址)，与出口段标识“2001”对应的段IP地址10.0.0.3(始节点IP地址)和10.0.0.3(终节点IP地址)，以及出口段标识“1003”对应的段IP地址10.0.0.3(始节点IP地址)和10.0.0.4(终节点IP地址)，。和/或，Rep 102的配置信息还可以包括：与入口段标识“1001”对应的段标签“501”，与出口段标识“2001”对应的段标签“20”，以及与出口段标识“1003”对应的段标签“503”。

S102：向多个节点配置相应的配置信息。
在本申请实施例中，S102和S202的执行主体是控制器，该控制器可以独立于各个节点，也可以部署于其中一个节点，例如第一边缘节点。
如果控制器独立于各个节点，那么控制器可以通过向各个节点发送对应的配置信息来实现为各个节点配置相应配置信息的目的，即控制器向第一边缘节点发送第一配置信息，向第二中继节点发送第二配置信息，向第二边缘节点发送第三配置信息，向第四边缘节点发送第四配置信息或第五配置信息。具体的，控制器可以通过网络配置协议(network configuration protocol，Netconf)、Restconf协议、路径计算原件通信协议(path computation element communication protocol，PCEP)、边界网关协议(border gateway protocol，BGP)，或者Openflow等协议向各个节点发送对应的配置信息。其中，RESTCONF协议用于提供遵循表述性状态转移(representational state transfer，REST)原理的超文本传输协议(hypertext transfer protocol，HTTP)接口，并与NETCONF数据存储模型兼容。可选的，控制器可以向各个节点分别发送对应的远程过程调用指令(remote procedure call，RPC)，在该指令中包含各个节点对应的配置信息。
如果控制器部署于第一边缘节点，那么第一边缘节点可以直接根据第一配置信息进行配置，并且向其他节点发送对应的配置信息来实现为各个节点配置相应配置信息的目的，即第一边缘节点向第二中继节点发送第二配置信息，向第二边缘节点发送第三配置信息，向第四边缘节点发送第四配置信息或第五配置信息。

在本申请实施例中，多个节点在获取到对应的配置信息之后，可以根据对应的配置信息配置相应的模块。
例如，第一边缘节点在获取到第一配置信息后，可以配置复制模块，第一边缘节点的复制模块用于复制接收到的数据包，并向第一中继节点输出复制所获得的第一数据包以及向第二中继节点输出复制所获得的第二数据包。
第一中继节点在获取到第二配置信息后，可以配置复制模块和消除模块。第一中继节点的复制模块用于复制所述第一数据包，并向所述第二中继节点输出复制所获得的第三数据包。第一中继节点的消除模块用于从复制所获得的第四数据包和来自所述第二中继节点的数据包中获取先接收到的数据包并向第二边缘节点发送。
第二边缘节点在获取到第三配置信息后，可以配置消除模块。第二边缘节点的消除模块用于从接收到的来自所述第一中继节点的数据包和来自所述第二中继节点的数据包中获取先接收到的数据包并输出。
第二中继节点在获取到第四配置信息后，可以配置复制模块和消除模块。第二中继节点的复制模块用于复制来自于所述第一边缘节点的第二数据包，并向第一中继节点输出复制所获得的第五数据包。第二中继节点的消除模块用于从复制所获得的第六数据包和来自所述第一中继节点的第三数据包中获取先接收到的数据包并向所述第二边缘节点发送。
或者，第二中继节点在获取到第五配置信息后，可以配置消除模块和复制模块。第二中继节点的消除模块用于从来自于所述第一边缘节点的第二数据包和来自所述第一中继节点的第三数据包中获取先接收到的数据包。第二中继节点的复制模块用于对该一个数据包进行复制，并向所述第一中继节点输出复制所获得的第五数据包以及向所述第二边缘节点输出复制所获得的第六数据包。
作为一种可能实现的方式，各个节点可以基于各自配置信息中包括的入口信息和出口信息生成转发面的转发表项，以实现相应的转发功能。
一个节点在转发面的转发表项可以包括该节点包括的功能模块的标识，以及该功能模块的入标签和出标签。其中，如果配置信息中没有段标签，则转发面可以根据段标识和段标签之间的映射关系来确定与段标识对应的段标签。具体的，与入口段标识对应的段标签为入标签，与出口段标识对应的段标签为出标签。
例如，参见表3，该表为Relay C在转发面的转发表项。
表3
Figure PCTCN2019113506-appb-000003
为了实现节点在转发面对数据包的转发，每个功能模块在输出数据包时，需要在数据包中打上出标签(可以是增加标签或者替换标签)。这样下一个节点在接收到数据包之后，可以解析到该数据包在上个节点打上的出标签，对于本节点而言即为入标签，然后根据入标签查询转发表项，确定对应的出标签。
例如，如果Relay C的复制模块接收到一个具有标签为501的数据包，查找表3，确定对于与功能模块的标识为Rep的功能模块，对应的出标签为31和503，且，即说明需要对该具有标签501的数据包进行复制，并将复制得到的两个数据包分别打上出标签31和出标签503，并通过对应的链路发送出去。而Relay C的消除模块接收到被Relay C的复制模块打上了出标签31的数据包之后，查找表3，确定对于功能模块的标识为Elm的功能模块，对应的出标签为502。所以Relay C的消除模块在接收到被上个节点打上了出标签504的数据包之后，从两个数据包中获取一个并通过出标签为502的链路输出。
此外，需要说明的是，在本申请实施例中提到的“链路”可以是物理连接，也可以是虚拟连接。
在上述实施例中，中继节点的个数是两个，在实际应用中，中继节点的个数可以多于两个。下面以中继节点的个数为四个为例进行详细介绍。由于中继节点的个数为四个的实施例和与为两个的实施例是类似的，所以一些相同或相似之处不再赘述，参考上文即可。
参见图4，该图为其中一种可能的多个节点的架构示意图。在该图中，包括第一边缘节点Edge A’、第二边缘节点Edge B’和四个中继节点，这四个中继节点分别包括第一中继节点Relay C’、第二中继节点Relay D’、第三中继节点Relay E’和第四中继节点Relay F’。其中，Edge A’、Relay C’和Relay D’之间相互连接，Relay C’、Relay D’、Relay E’和Relay F’之间相互连接，Relay E’、Relay F’和Edge B’之间相互连接。

路径16：Edge A’→Relay D’→Relay C’→Relay F’→Relay E’→Edge B’。
CE1发送的业务流可以同时从Edge A’经过这十六条路径中传输到Edge B’，从而到达CE2。只要有一条路径没有发生故障，就可以保证CE2接收到业务流。为了确保业务流中的数据包可以从这十六条路径经过，可以为第一边缘节点Edge A’、第二边缘节点Edge B’、第一中继节点Relay C’、第二中继节点Relay D’、第三中继节点Relay E’和第四中继节点Relay F’生成对应的配置信息，以配置相应的模块。
