Description

报文处理方法及其装置
本申请要求于2020年7月6日提交中国国家知识产权局，申请号为202010642126.4，发明名称为“报文处理方法及其装置”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
本申请涉及通信技术领域，尤其涉及一种报文处理方法及其装置。
背景技术
随着人们日常生活对网络的依赖日趋全面化,从低带宽单一的业务应用到语音、视频等实时传送的多业务应用,导致了数据流量的急剧增长,对现有网络的性能形成了很大压力。所以有必要在网络架构和路由器硬件系统结构方面作进一步探索,研究一种高速、低成本、可扩展的硬件系统来满足目前网络发展的需求,推动网络服务质量的提高。
目前，互联网协议(Internet Protocol,IP)技术是现有网络通信的核心技术。路由器设备通过信令确定网络拓扑，创建、维护和更新路由表(routing information base，RIB),并根据路由表内容创建、维护和更新转发表(forwarding information base，FIB)。路由器设备通过查找转发表，实现对报文的转发。
而随着网络规模的扩大，网络用户和业务越来越多，网络设备中的媒体访问控制(media access control，MAC)表、RIB、FIB等表项目爆炸式增加，成为制约网络规模的关键因素。因此，如何解决网络规模受制约的问题是当前亟待解决的问题。
发明内容
本申请实施例提供了一种报文处理方法及其装置，用于实现节点设备无表转发的方案，解决了由于网络表项目爆炸式增加导致网络规模受制约的问题。
本申请实施例第一方面提供一种报文处理方法，该方法包括：
第一业务节点获取第一业务数据，该第一业务数据携带第一业务信息，该第一业务信息用于指示该第一业务数据所对应的业务；然后，第一业务节点根据第一业务信息确定第一路径矢量(path vector，PV)，该第一路径矢量包括一个或多个节点的端口的端口信息；第一业务节点生成包含第一路径矢量的第一报文，该第一路径矢量用于第一业务节点发送该第一报文。
本实施例中，第一业务节点根据第一业务信息确定第一路径矢量，并生成包含第一路径矢量的第一报文。其中，该第一路径矢量用于第一业务节点发送该第一报文，且该第一路径矢量包括一个或多个节点的端口的端口信息，从而实现节点设备无表转发的方案，解决了由于网络表项目爆炸式增加导致网络规模受制约的问题。另外，第一报文携带第一路径矢量，无需通过域名系统(domain name system，DNS)服务器确定目的IP地址，缩短了第一业务节点执行数据请求的时延，减少信令开销。无需DNS服务器重定向等集中性节点，提高数据传输的可靠度性。
一种可能的实现方式中，该方法还包括：若第一路径矢量包含第一业务节点的端口信息，则第一业务节点发送包含第二路径矢量的第一报文，该第二路径矢量为删除第一路径矢量中的第一业务节点的端口信号后的路径矢量；若第一路径矢量不包含第一业务节点的端口信息，则第一业务节点发送包含第一路径矢量的第一报文。
在该可能的实现方式中，提供了一种第一业务节点根据第一路径矢量发送第一报文的方式。由此可知，第一业务节点根据第一路径矢量发送第一报文，是一种无表转发的方式，数据转发不涉及查表操作，节点设备简单高效，转发时延较低。另外，第一业务节点根据第一路径矢量发送第一报文，不存在IP地址枯竭的问题，传输效率较高，转发时延较小。
另一种可能的实现方式中，该第一业务节点根据第一业务信息确定第一路径矢量，包括：第一业务节点根据第一路径矢量映射关系确定第一业务信息对应的第一路径矢量，该第一路径矢量映射关系用于指示第一业务信息与第一路径矢量之间的映射关系。
在该可能的实现方式中，提供了一种具体的第一业务节点根据第一业务信息确定第一路径矢量的方式，提升方案的可实现性。
另一种可能的实现方式中，该第一业务信息与第一路径矢量之间的映射关系，包括：第一业务信息包括第一业务标识；第一业务节点根据第一业务标识确定第一转发路径，该第一转发路径的起始节点为第一业务节点，第一转发路径的目的节点为第二业务节点，该第二业务节点用于为第一业务节点提供第一业务标识所对应的业务服务；第一业务节点根据第一端口信息生成第一路径矢量，第一端口信息为第一转发路径上的节点用于输出的端口的端口信息。
在该可能的实现方式中，提供的第一路径矢量映射关系的一种具体的形式，通过第一业务信息确定对应的第一转发路径，并通过该第一转发路径上的节点用于输出的端口的端口信息生成第一路径矢量。
另一种可能的实现方式中，该方法包括：第一业务节点通过路由协议获取第二端口信息和第二业务标识，该第二端口信息为第一网络包括的节点的端口的端口信息，该第二业务标识为第一网络包括的业务节点所支持的业务的业务标识，该第一网络为第一业务节点接入的网络；然后，第一业务节点根据第二端口信息和第二业务标识生成一个或多个转发路径，该一个或多个转发路径包括第一转发路径。
在该可能的实现方式中，在第一业务节点的控制面上，第一业务节点运行路由协议，获取第二端口信息和第二业务标识，并生成一个或多个转发路径。由此可知，每个转发路径的目的节点都有对应的业务标识，以便于第一业务节点生成一个或多个路径矢量。
另一种可能的实现方式中，第一网络包括一个或多个虚拟节点，该虚拟节点包括入口子节点和出口子节点，该第二端口信息包括一个或多个虚拟节点的外部端口的端口信息，该外部端口为入口子节点的入口端口和出口子节点的出口端口。
在该可能的实现方式中，由于路径矢量包括的端口分量与转发路径上的节点的数量和端口号有关。对于小型网络，转发路径上的节点的数量相对较少，端口分量占用的二进制数的位数较少，即路径矢量包括的一个或多个端口分量的长度较短，数据传输效率较高。对于大型网络，本申请实施例引入虚拟节点，通过虚拟节点聚合一个局部网络中的多个节 点，从而减少路径矢量的长度，减少节点设备计算路径矢量的计算量。
另一种可能的实现方式中，该第一端口信息包括一个或多个端口分量，该端口分量与第一转发路径上的节点中用于输出的端口对应；该第一业务节点根据第一端口信息生成第一路径矢量，包括：第一业务节点按照预设的密钥分别对该一个或多个端口分量加密，并生成第一路径矢量。
在该可能的实现方式中，第一路径矢量包括的一个或多个端口分量是经过加密得到的。因此，第一转发路径上的每个节点只确定该第一报文的下一跳节点，并无法获取第一报文的起始节点和目的节点，从而提高了业务节点之间进行数据通信的安全性和可靠性，增加本方案的实用性。
另一种可能的实现方式中，对一个或多个端口分量加密的密钥不相同。
在该可能的实现方式中，用于加密每个端口分量的密钥不相同，这样有利于提高数据传输的安全性和可靠性。
另一种可能的实现方式中，第一业务节点根据第一端口信息生成第一路径矢量，包括：该第一业务节点根据加密后的第一端口信息生成第一路径矢量。
在该可能的实现方式中，该一个或多个端口分量分别是由第一转发路径上对应的节点加密得到的，即与前述第一业务节点按照预设的密钥加密该一个或多个端口分量是两种并列的方案，在本实现方式中，第一业务节点与第一转发路径上的其他节点无需提前约定密钥，减少密钥约定信令，减少网络开销；并且，密钥无需提前约定，可以提高数据传输的安全性。
另一种可能的实现方式中，该第一路径矢量包括至少一个节点的端口分量；该第一业务节点发送包含第二路径矢量的第一报文，包括：第一业务节点根据第一路径矢量的第一个端口分量确定第一业务节点的第一端口；然后，第一业务节点删除第一路径矢量的第一个端口分量，得到第二路径矢量；第一业务节点通过第一业务节的第一端口发送包含第二路径矢量的第一报文。
在该可能的实现方式中，提供了第一业务节点根据第一路径矢量发送第一报文的具体方式。第一业务节点在转发第一报文时，应当将该第一路径矢量包含的该第一业务节点的端口信息删除，再转发该第一报文。
另一种可能的实现方式中，第一业务节点根据第一路径矢量的第一个端口分量确定第一业务节点的第一端口，包括：第一业务节点确定第一业务节点包含的端口数量；然后，第一业务节点根据该端口数量确定第一位宽X，该第一位宽X为用于表示第一业务节点的第一端口的端口信息的二进制数形式的位宽，其中，X为大于或等于1的整数；第一业务节点将第一路径矢量的前X位二进制数作为第一端口的端口信息。
在该可能的实现方式中，提供了第一业务节点确定第一路径矢量的第一个端口分量的第一种方式。其次，由于第一路径矢量包括的是一个或多个端口分量，第一转发路径上的节点对其之前或之后的端口分量不可知，端口分量仅有本地意义，无法获知是哪两个业务节点之间的数据通信，从而提高数据传输的安全性。
另一种可能的实现方式中，第一业务节点根据第一路径矢量的第一个端口分量确定第 一业务节点的第一端口，包括：第一业务节点判断第一份二进制数中的首位二进制数的数值是否为第一数值，该第一份二进制数为该第一路径矢量的前Y位二进制数，Y为预设的用于表示第一业务节点的端口的端口信息的二进制数形式的单位位宽，其中，Y为大于或等于1的整数；若该首位二进制数的数值为所述第一数值，则该第一业务节点判断第二份二进制数中的首位二进制数的数值是否为所述第一数值，若否，则将去除首位二进制数的该第一份二进制数放置到去除首位二进制数的第二份二进制数之后，获取Y-2位二进制数序列，将该Y-2位二进制数序列作为该第一端口的端口信息，该第二份二进制数为该第一路径矢量的第Y+1位二进制数至该第一路径矢量的第2Y位二进制数；若该首位二进制数的数值不为该第一数值，则该第一业务节点将去除首位二进制数的该第一份二进制数作为该第一端口的端口信息。
在该可能的实现方式中，提供了第一业务节点确定第一路径矢量的第一个端口分量的第二种方式，提升方案的多样性。
另一种可能的实现方式中，第一报文还携带第一业务节点的第一信源信息，该第一信源信息包括以下任一种信息：互联网协议(internet protocol，IP)地址、媒体接入控制(media access control，MAC)地址、名称、或者、身份标识(identity，ID)。
在该可能的实现方式中，第一报文携带第一信源信息，以便于在目的节点接收到第一报文之后，目的节点向该第一业务节点反馈数据时，可以通过该第一信源信息找到该第一业务节点。
另一种可能的实现方式中，该方法还包括：第一业务节点根据第一业务信息确定多个路径矢量，该多个路径矢量与多个转发路径一一对应；该第一业务节点获取多份业务数据，该多份业务数据与该多个路径矢量一一对应，该多份业务数据分别携带该第一业务信息；该第一业务节点分别将该多份业务数据映射至该多个路径矢量中对应的路径矢量，该映射用于该多个转发路径的负载均衡。
在该可能的实现方式中，第一业务节点获取多份业务数据，第一业务节点按照负载均衡的规则将多份业务数据映射至多个路径矢量中对应的路径矢量，这样有利于多个路径矢量对应的多个转发路径的负载均衡，提高数据传输效率，提升网络传输性能。
另一种可能的实现方式中，第一业务节点根据第一业务信息确定第一路径矢量，包括：第一业务节点判断是否存在第一业务信息对应的第一路径矢量；若是，则第一业务节点确定该第一业务信息对应的第一路径矢量；若否，则该第一业务节点确定第一默认路径矢量为所述第一路径矢量，该第一默认路径矢量所指向的目的节点为代理节点；其中，该代理节点为代理该第一业务节点与第三业务节点进行通信的网关设备，且该代理节点用于向该第三业务节点发送该第一报文，以使得该第三业务节点为该第一业务节点提供该第一业务数据所对应的业务服务。
在该可能的实现方式中，在网络系统的多部分网络中设立分级网关设备，第一业务节点只需要计算用于该第一业务节点到达该第一网络中的业务节点的路径矢量，如果查找不到对应的路径矢量，就通过默认路径矢量向代理节点发送报文，再由代理节点进一步处理该报文并转发该报文。这样既能够完成报文的传输，又能够减小第一业务节点计算路径矢 量的计算量，降低对第一业务节点的性能要求。
另一种可能的实现方式中，第一业务节点和第三业务节点归属同一网络或归属不同的网络。
另一种可能的实现方式中，第一网络为局域网，该第二网络为城域网；或者，该第一网络为城域网，该第二网络为广域网。
在该可能的实现方式中，提供了第一网络和第二网络多种可能的实现方式。

第一网络节点接收包含第三路径矢量的第一报文，该第三路径矢量包括一个或多个节点的端口的端口信息；该第一网络节点根据该第三路径矢量发送该第一报文。
本实施例中，该第一网络节点根据该第三路径矢量发送该第一报文，从而实现节点设备无表转发的方案，解决了由于网络表项目爆炸式增加导致网络规模受制约的问题。并且，由于路径矢量不需要统一分配，不存在IP地址枯竭的问题，能适应各种类型的网络。

在该可能的实现方式中，提供了第一网络节点发送第一报文的具体方式。由此可知，第一网络节点根据第三路径矢量发送第一报文，是一种无表转发的方式，数据转发不涉及查表操作，节点设备简单高效，转发时延较低。另外，第一网络节点根据第三路径矢量发送第一报文，不存在IP地址枯竭的问题，传输效率较高，转发时延较小。

在该可能的实现方式中，在引入虚拟节点的场景下，第一网络节点作为第一虚拟节点的第一入口子节点，提供了第一网络节点确定第一子路径矢量，并根据该第一子路径矢量和该第三路径矢量发送该第一报文的过程。
另一种可能的实现方式中，该第一网络节点根据该第一子路径矢量和该第三路径矢量发送该第一报文，包括：该第一网络节点根据该第一子路径矢量的第一个端口分量确定该第一网络节点的第二端口；该第一网络节点删除该第一子路径矢量的第一个端口分量，得第二子路径矢量；该第一网络节点通过该第一网络节点的第二端口发送包含该第二子路径矢量和该第三路径矢量的第一报文。

本实施例中，第一业务节点只需要计算用于该第一业务节点到达该第一网络中的业务节点的路径矢量，如果查找不到对应的路径矢量，就通过默认路径矢量向代理节点发送报文，再由代理节点进一步处理该报文并转发该报文。这样既能够完成报文的传输，又能够减小第一业务节点计算路径矢量的计算量，降低对第一业务节点的性能要求。

具体实施方式
本申请实施例提供了一种报文处理方法及其设备，用于实现节点设备无表转发的方案，解决了由于网络表项目爆炸式增加导致网络规模受制约的问题。
下面对本申请所涉及的一些术语进行介绍。
业务节点：指充当业务提供者或业务消费者的节点设备。例如，终端设备、服务器、虚拟机(virtual machine，VM)或容器等。
网络节点：用于连接业务节点的节点设备。例如，路由器、交换机等。
路径矢量：包括转发路径上的一个或多个节点的端口的端口信息，用于该转发路径上的节点沿着该转发路径的转发方向向该转发路径的目的节点发送报文。例如，如图1A所示，虚线部分所示的转发路径为A→a→b→e→f→C，该转发路径的转发方向为：业务节点A指向网络节点a，网络节点a指向网络节点b，网络节点b指向网络节点f，网络节点f指向业务节点C。该转发路径的目的节点为业务节点C。路径矢量包括业务节点A的端口信息、网络节点a端口的端口信息、网络节点b的端口的端口信息、网络节点e的端口的端口信息和网络节点f的端口的端口信息，该转发路径的的节点根据路径矢量向业务节点C转发报文。
端口信息：包括有线网络中节点的物理端口号，或者，无线网络中的无线信道号(例如，频段信息、时间片信息、或码信息)。可选的，端口信息包括端口分量，端口分量用于表示节点的物理端口号或无线信道号。
虚拟节点：由网络中的至少两个子节点组成。虚拟节点可以按照公司部门网络划分，或者，按照地域网络划分，或者按照管理方便划分等，具体本申请不做限定。例如，如图1B所示，虚拟节点1包括多个网络节点，该多个网络节点称为该虚拟节点包括的子节点，虚拟节点1包括子节点h、子节点i、子节点j、子节点k和子节点l。虚拟节点1和虚拟节点2分别为某公司两个不同部门网络包括的节点组成的虚拟节点。虚拟节点内部可以是一个支持路径矢量的网络或者是一个兼容现有技术的网络(例如IP网络或以太网络)。
虚拟节点的入口子节点和出口子节点：相对于某个报文的流向来说，虚拟节点包括入口子节点和出口子节点。对于该报文的流向来说，入口子节点用于从除该虚拟节点包括的子节点之外的其他节点接收该报文，出口子节点用于向除该虚拟节点包括的子节点之外的其他节点发送该报文。例如，如图1B所示，报文1从业务节点A向业务节点C传输。那么相对于报文1的流向来说，虚拟节点1的入口子节点为子节点h，即通过子节点h从业务节点A接收该报文1。出口子节点为子节点l，即通过子节点l向虚拟节点4的子节点m发送该报文1。
入口子节点的入口端口：指相对于某个报文的流向来说，入口子节点用于接收该报文的端口。例如，如图1B所示，业务节点A通过业务节点A的端口1向虚拟节点1的子节点h发送报文1，子节点h通过子节点h的端口3接收该报文1。可以理解的是，子节点h的端口3为子节点h的入口端口。
出口子节点的出口端口：指相对于某个报文的流向来说，出口子节点用于发送该报文的端口。例如，如图1B所示，业务节点A向业务节点C发送报文1。虚拟节点1的子节点l接收该报文1，并通过虚拟节点1的子节点l的端口2向虚拟节点4的子节点m发送该报文1。可以理解的是，虚拟节点1的子节点l的端口2为子节点l的出口端口。
虚拟节点的外部端口：指虚拟节点对其他节点开放的端口。例如，如图1B所示，虚拟 节点1的外部端口包括子节点h的端口3、子节点l的端口2和子节点j的端口1。
转发路径上的节点用于输出的端口：指相对于转发路径的转发方向来说，转发路径上的一个节点向在该转发路径上的下一个节点发送报文的端口。例如，如图1A所示，虚线箭头部分的转发路径为A→a→b→e→f→C，虚线箭头用于表示该转发路径的转发方向，则可知业务节点上用于输出的端口为端口1，网络节点a上用于输出的端口为端口2。其他节点类似，不再一一说明。
需要说明的是，为了便于描述和查看，在后文中，路径矢量包括一个或多个端口分量，每个端口分量之间通过逗号分隔。而实际应用中，路径矢量不包含逗号。例如，路径矢量[1,010,11,10,100]，实际应用中，应当表示为[10101110100]。
需要说明的是，为了便于描述，在后文中，转发路径通过按照转发路径的转发方向依次示出该转发路径上的节点。例如，转发路径A→a→b→e→f→C，该转发路径的转发方向为：业务节点A指向网络节点a，网络节点a指向网络节点b，网络节点b指向网络节点f，网络节点f指向业务节点C。
本申请实施例中，节点设备在一些场景下充当业务节点；而在另外一些场景下，该节点充当网络节点。即一个节点设备可以为业务节点，也可以为网络节点，具体视实际应用场景而定。在后文中以场景的方式展开，如果在对应的场景中该节点设备充当业务节点，即标为业务节点；如果该节点设备充当网络节点，即标为网络节点。并不属于对节点设备的功能作限定。

例如，如图1A所示，第一转发路径为A→a→b→e→f→C。业务节点C用于为业务节点A提供“王者荣耀”游戏的业务服务。即第一转发路径上的节点包括业务节点A，网络节点a、网络节点b、网络节点e、网络节点f和业务节点C。业务节点A为第一转发路径的起始节点，业务节点C为第一转发路径的目的节点。在第一转发路径上，业务节点A上用于输出的端口为业务节点A的端口1，网络节点a上用于输出的端口为网络节点a的端口2，网络 节点b上用于输出的端口为网络节点b的端口3，网络节点e上用于输出的端口为网络节点e的端口2，网络节点f上用于输出的端口为网络节点f的端口4。
因此，第一路径矢量包括：业务节点A的端口1的端口信息、网络节点a的端口2的端口信息、网络节点b的端口3的端口信息、网络节点e的端口2的端口信息和网络节点f的端口4的端口信息。可选的，由于业务节点A只包括一个端口，所以第一路径矢量不携带该业务节点A的端口1的端口信息。
可选的，该第一端口信息包括一个或多个端口分量，且端口分量与第一转发路径上的节点中用于输出的端口对应。
一种可能的实现方式中，端口分量用于表示该用于输出的端口的端口号。而端口分量的表示形式有多种，例如，端口分量为二进制数形式的端口分量，或者，为十六进制数形式的端口分量，或者，为十进制数形式的端口分量，具体本申请不做限定。下面通过二进制数形式的端口分量介绍第一路径矢量。
二进制数形式的端口分量的表示方式有多种，下面结合具体示例介绍两种可能的实现方式。
实现方式一：请参阅表1，表1示出了第一端口信息包括的一个或多个端口分量的二进制数形式的一种表示方式。
表1
Figure PCTCN2021103987-appb-000001
如表1所示，业务节点A包括的端口数量为1，则通过一位二进制数即可表示该业务节点A的端口的端口分量，所以用于表示业务节点A的端口的端口号的二进制数形式的位宽为1。第一转发路径上的业务节点A用于输出的端口为端口1，端口1对应的端口分量为1。
网络节点a包括的端口数量为8，即通过三位二进制数即可表示该网络节点a的端口的端口分量，所以用于表示网络节点a的端口的端口号的二进制数形式的位宽为3。第一转发路径上网络节点a用于输出的端口为端口2，端口2对应的端口分量为010。第一转发路径上的其他节点用于输出的端口的端口分量类似，这里不再一一说明。
由此可知，第一路径矢量为[1,010,11,10,100]，端口分量与用于输出的节点的端口一一对应。如表1可知，节点A的端口1对应端口分量1，节点a的端口2对应端口分量010，以此类推。可选的，由于节点A只包括端口1，所以第一路径矢量可以不包括节点A的端口1的端口分量，则第一路径矢量为[010,11,10,100]。
实现方式二：请参阅表2，表2示出了第一端口信息包括的一个或多个端口分量的二进制数形式的另一种表示方式。
表2
Figure PCTCN2021103987-appb-000002
如表2所示，单位位宽指预设的用于表示用于输出的端口的端口分量的二进制数形式的单位位宽。如表2所示，该单位位宽为4，即单位位宽对应四位二进制数。而单位位宽对应的四位二进制数中的首位二进制数为连续标识位，后三位二进制数用于表示端口的端口分量。同理，单位位宽也可以为8，即单位位宽对应8位二进制数，而单位位宽对应的8位二进制数中的首位二进制数为连续标识位，后7位二进制数用于表示端口的端口分量，等等。
下面通过举例介绍连续标识位的作用。
如表2所示，网络节点a包括的端口数量为8，如果要表示该网络节点a的所有端口的端口分量，那么至少需要四位二进制数表示。这里以网络节点a的端口8为例作介绍，端口8的端口分量应当表示为10000001。“10000001”的前四位二进制数中的首位二进制数为“1”，代表10000001”中的后四位二进制数“0001”也属于该端口8的端口分量的一部分。而“10000001”中的后四位二进制数中的首位二进制数为“0”，则代表“10000001”即为该端口8的端口分量，无需再继续读取路径矢量中的第八位二进制数之后的二进制数。然后，网络节点a去除前四位二进制“1000”中的首位二进制数，得到“000”。网络节点a去除后四位二进制“0001”中的首位二进制数，得到“001”。再将“001”放在“000”之前，即得到“001000”，即为“1000”为该端口8的端口分量。
如表2所示，业务节点A用于输出的端口为端口1，端口1对应的端口分量为001。网络节点a用于输出的端口为端口2，端口2对应的端口分量为010。第一转发路径上的其他节点用于输出的端口的端口分量类似，这里不再赘述。
由此可知，第一路径矢量为[0001,0010,0011,0010,0100]，端口分量与用于输出的节点的端口一一对应。结合表2所示，业务节点A对应端口分量0001，网络节点a对应端口分量0010，以此类推。可选的，由于业务节点A只包括端口1，所以第一路径矢量可以不包括业务节点A的端口1的端口分量，则第一路径矢量为[0010,0011,0010,0100]。
可选的，该一个或多个端口分量还可以有其他表示方式。例如，确定该网络系统的节点中，包括端口数量最多的节点，然后，根据该端口数量确定用于表示该节点的端口的端口分量的位宽。再通过该位宽所对应的多位二进制数分别表示该第一转发路径上的节点的 端口分量。如图1A所示，假设网络节点f包括的端口数量最多，为8个端口，则可知用于表示该网络系统的节点的位宽为4，即通过四位二进制数表示该网络系统中的端口的端口分量。
一种可能的实现方式中，步骤202具体包括步骤202a。
步骤202a：第一业务节点根据第一路径矢量映射关系确定第一业务信息对应的第一路径矢量。
其中，该第一路径矢量映射关系用于指示第一业务信息与第一路径矢量之间的映射关系。下面以第一业务标识为Service ID为例并通过表3介绍该第一路径矢量映射关系。需要说明的是，第一路径映射关系可以通过表格形式表示，也可以通过其他形式表示，具体本申请不做限定。关于第一路径矢量映射关系的相关说明请参阅后文图3A所示的实施例，这里不再赘述。
表3
Service ID 路径矢量
Service ID1 路径矢量1
Service ID2 路径矢量2
Service ID3 路径矢量3
Service ID4 路径矢量4
若第一业务信息为Service ID1，那么由表3可知，Service ID1对应路径矢量1。
203、第一业务节点生成包含第一路径矢量的第一报文。
可选的，该第一报文还携带该第一业务节点的第一信源信息。该第一信源信息包括以下任一种信息：IP地址、MAC地址、名称、或者、ID。
具体的，第一业务节点生成第一报文，并在第一报文的报文头中放入该第一路径矢量。
可选的，第一报文为IP报文或者以太网报文。其中，以太网报文也称为以太网帧。
为了第一业务节点兼容IP报文的封装格式，第一业务节点将第一路径矢量放在IP报文的目标地址(destination address)域，将第一业务节点的第一信源信息放在该IP报文的源地址(source address)域。或者是，第一业务节点在该IP报文中增加一个IP子报文头，并在该IP子报文头放入该第一路径矢量。
为了第一业务节点兼容以太网报文的封装格式，第一业务节点将第一路径矢量放在以太网报文的目标地址(destination address)域，将第一业务节点的第一信源信息放在该以太网报文的源地址(source address)域。
需要说明的是，不考虑现有IP报文的封装格式和以太网报文的封装格式的情况下，第一业务节点可以重新定义一个新的报文头，该报文头包含该第一路径矢量和第一信源信息。
由步骤203可知，第一路径矢量包括一个或多个节点的端口的端口信息，且而端口信息可以为端口分量。而端口分量仅有本地意义，也就是说第一转发路径上的节点对第一路径矢量的其他端口分量并不可知是对应哪个节点的端口分量，这样数据传输过程中，第一转发路径上的节点无法获知该第一报文的目的节点和源节点，也就是就是无法获知是哪两个业务节点之间的通信，从而提高数据传输的安全性和可靠性。
204、若第一路径矢量包含第一业务节点的端口信息，则第一业务节点发送包含第二路径矢量的第一报文。
其中，该第二路径矢量为删除该第一路径矢量中的第一业务节点的端口信息后的路径矢量。
下面通过步骤204a至步骤204c介绍步骤204。
步骤204a：第一业务节点根据第一路径矢量的第一个端口分量确定第一业务节点的第一端口。
其中，第一业务节点确定第一端口的方式有多种，具体方式应当由步骤202中第一业务节点生成第一路径矢量的方式决定。下面分别基于步骤202中的实现方式一和实现方式二分别介绍步骤204a。
一、基于步骤202的实现方式一，步骤204a具体包括步骤1至步骤3。
步骤1：第一业务节点确定第一业务节点包含的端口数量。
例如，如图1A所示，第一业务节点为业务节点A，业务节点A确定业务节点A只包括一个端口，即业务节点A包含的端口数量为1。
步骤2：第一业务节点根据该端口数量确定第一位宽X。
其中，第一位宽X为用于表示第一业务节点的第一端口的端口信息的二进制数形式的位宽，X为大于或等于1的整数。
例如，结合上述表1，业务节点A包含的端口数量为1，那么用于表示业务节点A的第一端口的端口号的二进制数形式的位宽为1，即通过一位二进制数就可以表示该第一端口的端口号。
步骤3：第一业务节点将第一路径矢量的前X位二进制数作为第一端口的端口信息。
例如，第一路径矢量为[1,010,11,10,100]，第一路径矢量中的前1位二进制数为1,即将“1”作为第一端口的端口号的端口分量，第一端口为第一业务节点的端口1。可以理解的是，该第一路径矢量的前1位二进制数为该第一路径矢量的第一个端口分量。
二、基于步骤202的实现方式二，步骤204a具体包括步骤4至步骤6。
步骤4：第一业务节点判断第一份二进制数中的首位二进制数的数值是否为第一数值；若是，则执行步骤5；若否，则执行步骤6。
其中，第一份二进制数为第一路径矢量的前Y位二进制数，Y为预设的用于表示第一业务节点的端口的端口信息的二进制数形式的单位位宽，Y为大于或等于1的整数。
例如，第一数值为1。如表2所示，Y为4，第一路径矢量为[0001,0010,0011,0010,0100]，第一份二进制数为“0001”。由于“0001”中的首位二进制数为0，所以第一业务节点执行步骤6。
步骤5：第一业务节点判断第二份二进制数中的首位二进制数的数值是否为第一数值，若否，则将去除首位二进制数的该第一份二进制数放置到去除首位二进制数的第二份二进制数之后，获取Y-2位进制数序列，将该Y-2位二进制数序列作为第一端口的端口信息；
其中，第二份二进制数为第一路径矢量的第Y+1位二进制数至第一路径矢量的第2Y位二进制数。
例如，第一数值为1，单位位宽为4，第一路径矢量为[10000001,0011,0010,0100]，第一路径矢量的前4位二进制数为“1000”，则第一业务节点确定第一路径矢量的第5位二进制数至第八位二进制数(即“0010”)属于该第一个端口分量的一部分。第一业务节点通过“0010”中的首位二进制数确定无需再读取该第一路径矢量中的第八位二进制数之和的二进制数。然后，第一业务节点将“1000”中的首位二进制数去掉，得到“000”；将“0001”中的首位二进制数去掉，得到“001”。第一业务节点再将“001”放在“000”之前，即得到Y-2位二进制数序列“001000”，即为“001000”为该第一业务节点的第一端口的端口分量。
需要说明的是，如果第二份二进制数中的首位二进制数的数值不为第一数值，则第一节点再判断第三份二进制数的首位二进制数的数值是否为第一数值，具体操作与步骤5类似。
步骤6：第一业务节点将去除首位二进制数的第一份二进制数作为第一端口的端口信息。
例如，第一份二进制数为“0001”。第一业务节点将“0001”的首位去除，得到“001”，并将“001”作为第一端口的端口分量。具体的，第一业务节点通过计算二进制数“001”确定该第一端口为该第一业务节点的端口1。在步骤6中，第一路径矢量的第一个端口分量为第一路径矢量的前4位二进制数。
步骤204b：第一业务节点删除第一路径矢量的第一个端口分量，得到第二路径矢量。
例如，第一路径矢量为[1,010,11,10,100]，第一路径矢量中的前1位二进制数为第一路径矢量的第一个端口分量。例如，如图2B所示，业务节点A删除第一路径矢量中的第一位二进制数，得到第二路径矢量[010,11,10,100]。
再举例说明，第一路径矢量为[0001,0010,0011,0010,0100]，第一路径矢量中的前4位二进制数为第一路径矢量的第一个端口分量。如图2C所示，业务节点A删除第一路径矢量中的前4位二进制数，得到第二路径矢量[0010,0011,0010,0100]。
步骤204c：第一业务节点通过第一业务节点的第一端口发送包含第二路径矢量的第一报文。
例如，结合步骤204a的实现方式一可知，第一业务节点的第一个端口分量对应第一业务节点的端口1，第二路径矢量为[010,11,10,100]。如图2B所示，业务节点A通过业务节点A的端口1发送第一报文，该第一报文携带[010,11,10,100]。
再举例说明，结合步骤204a的实现方式二可知，第一业务节点的第一端口分量对应第一业务节点的端口1，第二路径矢量为[0010,0011,0010,0100]。如图2B所示，业务节点A通过节点A的端口1发送第一报文，该第一报文携带[0010,0011,0010,0100]。
205、若第一路径矢量不包含第一业务节点的端口信息，则第一业务节点发送包含第一路径矢量的第一报文。
例如，如上述表1和图1A所示，业务节点A只包括端口1，第一路径矢量为[010,11,10,100]。即第一路径矢量不包含业务节点A的端口1的端口分量。如图2D所示，业务节点A可以直接发送该包含第一路径矢量的第一报文。
再举例说明，如上述表2和图1A所示，节点A只包括端口1，第一路径矢量为[0010,0011,0010,0100]，即第一路径矢量不包含节点A的端口1的端口分量。如图2E所示，业务节点A可以直接发送该包含第一路径矢量的第一报文。
目前，网络设备通过转发表、路由表的方式，由于现有下发转发表和路由表时所占的带宽较大，并且转发表或路由表等表向的下发速率有性能瓶颈，无法适用于大规模网络，制约网络规模的扩大。而由上述方案可知，本申请实施例中，第一业务节点通过第一路径矢量实现对第一报文的转发，实现节点设备无表转发，节点设备转发报文简单高效。解决了IP路由转发带宽的主要瓶颈和网络规模受制约的问题。
另外，本申请实施例中，第一业务节点通过第一路径矢量发送报文，第一路径矢量包括一个或多个节点的端口的端口信息。相比于基于IP地址转发的方案，不存在地址枯竭的问题。并且，第一业务节点根据第一业务信息确定第一路径矢量，无需DNS服务器确定IP地址的过程，这样有利用提供报文传输效率，减小报文传输时延。由于无需DNS服务器确定目的IP地址的过程，可以避免信令交互，减少信令开销。
206、第一网络节点接收包含第三路径矢量的第一报文。
其中，第三路径矢量包括一个或多个节点的端口的端口信息，第一网络节点为第一转发路径上的任意一个网络节点。
例如，如图2B所示，第一转发路径为A→a→b→e→f→C，节点A为第一业务节点，那么第一网络节点为网络节点a、网络节点b、网络节点e和网络节点f中的任意一个网络节点。
下面基于上述步骤204介绍步骤206。对于步骤205的分支方案，步骤206的执行过程与基于步骤204下步骤206的执行过程类似，这里不一一说明。
基于步骤204的分支方案，若第一网络节点与第一业务节点直连，第三路径矢量与第二路径矢量相同；若第一网络节点与第一业务节点不直连，第三路径矢量与第二路径矢量不相同。
例如，如图2B所示，第一转发路径为A→a→b→e→f→C，业务节点A发送第一报文，第一报文携带第一路径矢量。当第一网络节点为网络节点a时，第三路径矢量与第二路径矢量相同，即第三路径矢量为[010,11,10,100]。当第一网络节点为网络节点b、网络节点e或网络节点f时，第三路径矢量与第二路径矢量不相同。例如，当第一网络节点为网络节点b时，第三路径矢量为[11,10,100]。
207、第一网络节点根据第三路径矢量发送第一报文。
下面结合步骤207a至步骤207c介绍步骤207。
步骤207a：第一网络节点根据第三路径矢量的第一个端口分量确定第一网络节点的第二端口。
步骤207a与前述步骤204a类似，具体请参阅步骤204a的相关介绍，这里不再赘述。
步骤207b：第一网络节点删除第三路径矢量的第一个端口分量，得到第四路径矢量。
步骤207b与前述步骤204b类似，具体请参阅步骤204b的相关介绍，这里不再赘述。
例如，如图2B所示，第一网络节点为网络节点a，第三路径矢量为[010,11,10,100]， 第一个端口分量为“010”，该第一个端口分量“010”对应网络节点a的端口2。网络节点a将[010,11,10,100]中的第一个端口分量删除，得到第四路径矢量[11,10,100]。
步骤207c：第一网络节点通过第二端口发送包含第四路径矢量的第一报文。
例如，如图2B所示，若第一网络节点为网络节点a，第四路径矢量为[11,10,100]。网络节点a通过网络节点a的端口2向网络节点b发送第一报文，该第一报文携带[11,10,100]。对于第一转发路径上的其他网络节点的转发过程类似，具体可以参阅图2B中的示例作理解。
需要说明的是，第一网络节点为第一转发路径上的最后一个网络节点时，第一报文携带的第四路径矢量不包含端口分量，即第一报文放置第四路径矢量的域是空的。例如，如图2B所示，第一网络节点为网络节点f，第四路径矢量不包含端口分量，则网络节点f通过网络节点f的端口4向业务节点C发送第一报文，该第一报文携带的第四路径矢量的域是空的。
由此可知，第一路径矢量包括一个或多个节点的端口的端口信息，且而端口信息可以为端口分量。而端口分量仅有本地意义，也就是说第一转发路径上的节点对第一路径矢量的其他端口分量并不可知是对应哪个节点的端口分量，这样数据传输过程中，第一转发路径上的节点无法获知该第一报文的目的节点和起始节点，也就是就是无法获知是哪两个业务节点之间的通信，从而提高数据传输的安全性和可靠性。并且，第一转发路径上的节点解读该节点对应的端口分量的解读方式可以不相同，这样可以进一步提高数据传输的安全性，且数据传输的灵活性更高。
208、第二业务节点接收第一报文。
其中，第二业务节点为第一路径矢量所指向的目的节点。第一报文携带第一业务信息、第一业务数据和第一业务节点的第一信源信息。其中，第一业务信息、第一信源信息和第一业务数据的相关说明请参阅前述步骤201中的相关介绍，这里不再赘述。
例如，如图2B所示，若步骤207中的第一网络节点为网络节点f，第二业务节点为业务节点C，网络节点f接收到第一报文，该第一报文携带的路径矢量PV＝[100]。那么，网络节点f确定该路径矢量PV＝[100]中的“100”为第一个端口分量，且该第一个端口分量对应网络节点f的端口4。网络节点f将该路径矢量PV＝[100]中的端口分量“100”删除，并通过网络节点f的端口4发送业务节点C发送第一报文。
一种可能的实现方式中，图2A所示的实施例中还包括步骤209至步骤214。
209、第二业务节点根据第一报文获取第二业务数据。
例如，如图2B所示，业务节点C接收业务节点A通过app请求的“王者荣耀”的游戏服务请求，业务点C根据该游戏服务请求获取“王者荣耀”的游戏数据，即为该第二业务数据。
210、第二业务节点根据第一信源信息确定第七路径矢量。
其中，第七路径矢量包括一个或多个节点的端口的端口信息。
一种可能的实现方式中，第七路径矢量包括第五转发路径上的节点用于输出的端口的端口信息。第五转发路径的起始节点为该第二业务节点，第五转发路径的目的节点为第一 业务节点。
例如，如图2F所示，第一业务节点为业务节点A，第二业务节点为业务节点C。第五转发路径为C→f→e→b→a→A。即第五转发路径上的节点包括业务节点C、网络节点f、网络节点e、网络节点b、网络节点a和业务节点A。在第五转发路径上，业务节点C用于输出的端口为业务节点C的端口1，网络节点f用于输出的端口为网络节点f的端口1，网络节点e用于输出的端口为网络节点e的端口3，网络节点b用于输出的端口为网络节点b的端口1，网络节点a用于输出的端口为网络节点a的端口3。因此，第七路径矢量包括：业务节点C的端口1的端口信息、网络节点f的端口1的端口信息、网络节点e的端口3的端口信息、网络节点b的端口1的端口信息和网络节点a的端口3的端口信息。具体第七路径矢量的表示方式与第一路径矢量的表示方式类似，具体请参阅前述步骤202的第一路径矢量的相关介绍，这里不再赘述。
可选的，第二业务节点根据第四路径矢量映射关系确定第一信源信息对应的第七路径矢量。
该第四路径矢量映射关系用于指示第一信源信息与第七路径矢量之间的映射关系。关于第四路径矢量映射关系的生成过程与后文图6A所示的实施例中步骤615中的第六路径矢量映射关系的生成过程类似，不同的地方仅在于第二业务节点生成的是第二业务节点到达第一网络中的业务节点的路径矢量，并建立第一网络中的业务节点的信源信息与路径矢量之间的映射关系。具体生成过程可以参考后文图6A所示的实施例中步骤615中的第六路径矢量映射关系的生成过程的相关说明。
下面以第一信源信息为该第一业务节点的信源名称为例，并通过表4介绍该第四路径矢量映射关系。需要说明的是，第四路径映射关系可以通过表格形式表示，也可以通过其他形式表示，具体本申请不做限定。
表4
节点的信源名称 路径矢量
信源名称1 路径矢量a
信源名称2 路径矢量b
信源名称3 路径矢量c
信源名称4 路径矢量d
若第一业务节点的信源名称为信源名称1，由表4可知，信源名称1对应路径矢量a。
211、第二业务节点生成包含第七路径矢量的第四报文。
212、若第七路径矢量包含第二业务节点的端口信息，则第二业务节点发送包含第八路径矢量的第四报文。
213、若第七路径矢量不包含第二业务节点的端口信息，则第二业务节点发送包含第八路径矢量的第四报文。
步骤211至步骤213与前述步骤203至步骤205类似，具体请参阅前述步骤203至步骤205的相关说明，这里不再赘述。
214、第一业务节点接收第四报文。
例如，如图2F所示，业务节点C通过如图2B中的虚线箭头部分的转发路径转发该第四报文，再由该第五转发路径上的最后一个网络节点a向业务节点A发送该第四报文，从而实现业务节点C为业务节点A提供第一业务数据所对应的业务服务。
本申请实施例中，第一业务节点获取第一业务数据，该第一业务数据携带第一业务信息，该第一业务信息用于指示第一业务数据所对应的业务；然后，第一业务节点根据该第一业务信息确定第一路径矢量，该第一路径矢量包括一个或多个节点的端口的端口信息；第一业务节点生成包含第一路径矢量的第一报文，该第一路径矢量用于第一业务节点发送该第一报文。由此可知，本申请实施例的技术方案中，第一业务节点根据第一业务信息确定第一路径矢量，并生成包含第一路径矢量的第一报文，以通过该第一路径矢量发送该第一报文，且该第一路径矢量包括一个或多个节点的端口的端口信息，从而实现节点设备无表转发的方案，解决了由于网络表项目爆炸式增加导致网络规模受制约的问题。
下面结合图3A介绍前述图2A所示的实施例中的步骤202a中的第一路径矢量映射关系的生成过程。请参阅图3A，该方法包括：
301、第一业务节点通过路由协议或相应的协议获取第二端口信息和第二业务标识。
其中，第二端口信息为第一网络包括的节点的端口的端口信息，第二业务标识为第一网络包括的业务节点所支持的业务的业务标识，该第一网络为第一业务节点接入的网络。
例如，如图3B所示的第一网络中，第一业务节点为业务节点A，业务节点A通过路由协议获取第一网络的其他节点的端口的端口信息和第一网络中的业务节点所支持的业务的业务标识。如图3B中，业务节点C为服务器，该业务节点C通过路由协议向第一网络的各个节点扩散该业务节点C的端口的端口信息(包括业务节点C的端口的端口号、业务节点C与邻居节点f之间的关系)以及业务节点C所支持的业务的业务标识。具体的扩散路径请参阅图3B中虚线箭头的路径。第一网络中的其他业务节点的端口信息和所支持的业务标识的扩散过程类似，这里不一一说明。
如图3B所示，网络节点f扩散其四个端口的端口信息(包括网络节点f的四个端口的端口号、网络节点f的四个端口的端口号与业务节点C之间的关系、网络节点f的四个端口的端口号与其他邻居节点之间的关系等)。第一网络中的其他网络节点的端口信息的扩散过程类似，这里不一一说明。
需要说明的是，由于在第一网络中的业务节点需要生成到达该第一网络的其他业务节点的路径矢量，所以各个节点在扩散信息时，可以只扩散至第一网络中的各个业务节点，无需扩散至第一网络中的全部节点。图3B示出了业务节点C的扩散信息扩散至业务节点A、业务节点B和业务节点D的示例。
由于路径矢量包括的端口分量与转发路径上的节点的数量和端口号有关。对于小型网络，转发路径上的节点的数量相对较少，端口分量占用的二进制数的位数较少，即路径矢量包括的一个或多个端口分量的长度较短，数据传输效率较高。并且，由于路径矢量不需要统一分配，不存在IP地址枯竭的问题，能适应各种类型的网络。
对于大型网络，本申请实施例引入虚拟节点，通过虚拟节点聚合一个局部网络中的多个节点。从而减少路径矢量的长度，减少节点设备计算路径矢量的计算量。
基于上述的问题，可选的，第一网络包括一个或多个虚拟节点，该第二端口信息包括一个或多个虚拟节点的外部端口的端口信息。
例如，如图1B所示，第一网络包括虚拟节点1、虚拟节点2、虚拟节点3和虚拟节点4。以虚拟节点4为例，虚拟节点4的外部端口为子节点m的端口1和子节点q的端口2。其他虚拟节点的外部端口请参阅图1B，这里不一一说明。
需要说明的是，图1B所示的第一网络仅仅是为了说明本申请实施例的技术方案中，实际应用中，虚拟节点中也可以包括业务节点，则在该情况下，第一业务节点还需获取该虚拟节点中的业务节点所支持的业务的业务标识。可选的，该第一网络也可以同时存在虚拟节点和独立的网络节点，那么第二端口信息还包括独立的网络节点的端口的端口信息。具体本申请不做限定，这里以图1B为示例作介绍。
302、第一业务节点根据第二端口信息和第二业务标识生成一个或多个转发路径。
其中，该一个或多个转发路径包括第一转发路径。
具体的，第一业务节点根据第二端口信息和第二业务标识生成以第一业务节点为起始节点的一个或多个转发路径。可选的，第一业务节点通过最短路径算法生成该一个或多个转发路径，例如，第一业务节点根据第二端口信息和第二业务标识生成一棵以第一业务节点为根，到其它各个业务节点的最短路径“树”。
例如，如图1A所示，业务节点A确定业务节点C支持的业务的业务标识为Service ID1，业务节点A生成业务节点A至业务节点C的最短转发路径，即如图1A所示的虚线部分的转发路径A→a→b→e→f→C。
针对第一网络包括一个或多个虚拟节点的方案，该第二端口信息包括一个或多个虚拟节点的外部端口的端口信息。例如，如图1B所示，业务节点A确定业务节点C支持的业务的业务标识为Service ID1，业务节点A生成业务节点A至业务节点C的最短转发路径，即如图1B所示的虚线部分的转发路径A→h→l→m→q→c→e→C。
303、第一业务节点根据该一个或多个转发路径和第二业务标识生成一个或多个路径矢量。
其中，第二业务标识包括第一业务标识，一个或多个转发路径包括第一转发路径。例如，第一业务节点根据步骤302中生成的最短路径“树”和第二业务标识生成一个或多个路径矢量。
下面以第一业务节点生成第一路径矢量为例说明步骤303，该第一路径矢量包括第一转发路径上用于输出的端口的端口信息。具体的，步骤303包括步骤303a和步骤303b。
303a、第一业务节点根据第一业务标识确定第一转发路径。
其中，第一转发路径的起始节点为第一业务节点，第一转发路径的目的节点为第二业务节点，第二业务节点用于为第一业务节点提供第一业务标识所对应的业务服务。
例如，如图1A所示，业务节点A为第一业务节点，业务节点A通过业务节点C发送的业务标识确定业务节点C支持第一业务标识所对应的业务，即业务节点C能够为业务节点C提供第一业务标识所对应的业务服务(例如，业务节点C能够为业务节点A提供“王者荣耀”游戏的业务服务)。业务节点A从一个或多个转发路径中查找目的节点为该业务节点 C的第一转发路径，具体第一转发路径为A→a→b→e→f→C。
针对第一网络包括一个或多个虚拟节点的场景作举例说明，如图1B所示，业务节点A确定业务节点C支持第一业务标识所对应的业务。即业务节点C能够为业务节点C提供第一业务标识所对应的业务服务(例如，业务节点C能够为业务节点A提供“王者荣耀”游戏的业务服务)。业务节点A从一个或多个转发路径查找目的节点为该业务节点C的第一转发路径，具体第一转发路径为A→h→l→m→q→c→e→C。
303b、第一业务节点根据第一端口信息生成第一路径矢量。
其中，第一端口信息为第一转发路径上用于输出的端口的端口信息。
具体的，该第一端口信息包括一个或多个端口分量，而端口分量的表示形式可以参阅前述图2A所示的步骤202中的相关介绍，这里不再赘述。
例如，如图1A所示，第一转发路径为A→a→b→e→f→C，结合前述步骤202中的表1可知，第一路径矢量可以表示为[1,010,11,10,100]。由于业务节点A只包括端口1，所以第一路径矢量可以不包括业务节点A的端口1的端口分量，则第一路径矢量为[010,11,10,100]。
再举例说明，如图1A所示，第一转发路径为A→a→b→e→f→C，结合前述步骤202中的表2可知，第一路径矢量可以表示为[0001,0010,0011,0010,0100]。由于业务节点A只包括端口1，所以第一路径矢量可以不包括业务节点A的端口1的端口分量，则第一路径矢量为[,0010,0011,0010,0100]。
针对第一网络包括一个或多个虚拟节点的场景，如图1B所示，第一转发路径A→h→l→m→q→c→e→C。第一端口信息包括一个或多个节点的端口分量，这里以端口分量为十六进制数形式来表示，那么由图1B可知，第一路径矢量为[1,2,2,2]。
为了提高报文传输的安全性，第一端口信息包括的一个或多个端口分量是经过加密的。具体的加密方式有多种，下面示出两种可能的实现方式。
实现方式一：第一业务节点按照预设的密钥分别对该一个或多个端口分量加密，并生成该第一路径矢量。
其中，用于加密端口分量的密钥相同或者不相同。
下面结合图3C介绍用于加密端口分量的密钥不相同的实现方式，对于用于加密端口分量的密钥相同的实现方式类似，这里不一一说明。例如，如图3C所示，第一转发路径上的网络节点a用于输出的端口为端口2，端口2所对应的端口分量为010。第一业务节点采用密钥1加密“010”，得到第一加密分量α 1。第一转发路径上的网络节点b用于输出的端口为端口3，端口3对于的端口分量为11。第一业务节点采用密钥2加密“11”，得到第二加密分量α 2。第三加密分量α 3和第四加密分量α 4的生成方式类似，具体此处不再一一说明。因此，第一路径矢量为[1,α 1,α 2,α 3,α 4]。
实现方式二：第一端口信息包括的每个端口分量分别由第一转发路径上对应的节点经过加密的得到的。第一业务节点根据加密的第一端口信息生成第一路径矢量。
其中，第一转发路径上的节点用于加密端口分量的密钥相同或不相同，具体本申请不做限定。
下面通过示例介绍加密的第一端口信息。例如，如图3B所示的第一网络中，业务节点C为服务器，该业务节点C通过路由协议向第一网络的各个节点扩散该业务节点C的加密的端口信息(包括业务节点C的端口的加密端口号、业务节点C的端口的加密端口号与邻居节点f之间的关系)以及业务节点C所支持的业务的业务标识。具体的扩散路径请参阅图3B中虚线箭头的路径。第一网络中的其他业务节点的端口信息和所支持的业务标识的扩散过程类似，这里不一一说明。
如图3B所示，网络节点f扩散其四个端口的端口信息(包括网络节点f的四个端口的加密端口号、网络节点f的四个端口加密的端口号与业务节点C之间的关系、网络节点f的四个端口的加密端口号与其他邻居节点之间的关系等)。第一网络中的其他网络节点的端口信息的扩散过程类似，这里不一一说明。
304、第一业务节点分别建立该一个或多个路径矢量与该第二业务标识之间的映射关系，得到第一路径矢量映射关系。
其中，第一路径矢量映射关系包括第一业务标识与第一路径矢量之间的映射关系。
下面以第一业务节点建立该第一业务标识与第一路径矢量之间的映射关系为例介绍步骤304。由上述步骤303a至步骤303b可知，第一业务节点通过第一业务标识确定第一转发路径，再由第一转发路径上的节点用于输出的端口的端口信息生成该第一转发路径。由此可知，第一业务标识与第一路径矢量之间具有映射关系，第一业务节点可以建立该第一业务标识与第一路径矢量之间的映射关系。
本申请实施例中，由上述步骤303b可知，为了提高报文传输的安全性，第一端口信息包括的一个或多个端口分量是经过加密得到的。基于该实现方式，上述图2A所示的实施例中的步骤207a具体包括步骤a和步骤b。
步骤a：第一网络节点按照预设的密钥对第三路径矢量的第一个端口分量进行解密，得到解密后的第一个端口分量。
其中，第一转发路径上的节点用于解密端口分量的密钥相同或不相同。具体取决于步骤303b中的第一路径矢量的生成方式。
进一步的，如果基于上述步骤303b中的实现方式一，即第一路径矢量包括的各个端口分量是第一业务节点加密得到的，则第一业务节点应当与该各个端口分量所对应的节点预先约定密钥。如果基于上述步骤303b中的实现方式二，即第一路径矢量包括的各个端口分量是由各个端口分量对应的节点分别加密的，则无需预先约定密钥。对于实现方式二，第一转发路径上的节点无需协商密钥，减少交互流程。
下面示出第一路径矢量包括的各个端口分量是由第一业务节点按照不同的密钥分别加密得到的示例。例如，如图3C所述，第一网络节点为网络节点a，第三路径矢量为[α 1,α 2,α 3,α 4]，α 1为第一路径矢量的第一个端口分量，用于加密第一个端口分量的密钥为密钥1。如图3D所示，网络节点a通过密钥1解密α 1，得到“010”。其中，业务节点A与网络节点a预先约定采用密钥1用于对端口分量“010”的加密和解密。对于第一转发路径上的其他节点解密该节点对应的端口分量的过程类似，这里不一一说明。
步骤b：第一网络节点通过解密后的第一个端口分量确定该第一网络节点的第二端口 的端口信息。
例如，解密后的第一端口分量为“010”，那么第一网络节点通过计算确定“010”对应第一网络节点的端口2，即第二端口的端口号为2。
那么在上述图2A所示的步骤207b具体包括：
第一网络节点删除加密的第一个端口分量，得到第四路径矢量。
例如，第三路径矢量为[α 1,α 2,α 3,α 4]，网络节点a删除第三路径矢量中的α 1，得到第四路径矢量[α 2,α 3,α 4]。对于第一转发路径上的其他节点删除该节点对应的端口分量的过程类似，这里不再一一说明。
本实施例中，第一网络节点通过第三路径矢量转发第一报文，由于第三路径矢量包括的一个或多个端口分量是经过加密得到的。因此，第一转发路径上的每个节点只确定该第一报文的下一跳节点，并无法获知该第一报文的起始节点和目的节点，从而提高了业务节点之间进行数据通信的安全性和可靠性，增加本方案的实用性。并且，第一转发路径上的每个节点解密该节点对应的端口分量时，采用的密钥可以不同，这样进一步提高了数据传输的安全性和可靠性。
本申请实施例中，第一网络包括一个或多个虚拟节点，第一网络节点为第一虚拟节点的第一入口子节点，第一虚拟节点包括第一入口子节点和第一出口子节点。那么在该实现方式下，上述图2A所示的实施例中的步骤207具体包括步骤1至步骤3。
步骤1：第一网络节点确定第三路径矢量的第一个端口分量对应第一出口子节点的第三端口。
例如，如图1B所示，第一虚拟节点为虚拟节点4，第一入口子节点为虚拟节点4中的子节点m，第一出口子节点为虚拟节点4中的子节点q。即第一网络节点为虚拟节点4中的子节点m。第三路径矢量为[2,2]，第三路径矢量的第一个端口分量为“2”。
由于每个虚拟节点的外部端口是确定的，且每个虚拟节点的外部端口对应的端口分量是唯一的。例如，在图1B中，虚拟节点4的外部端口包括子节点m的端口1和子节点q的端口2。子节点的端口1对应的端口分量为1，而子节点q的端口2对应的端口分量为2。因此，子节点m确定该第一个端口分量对应该虚拟节点4中的子节点q的端口2。
步骤2：第一网络节点确定第一子路径矢量。
其中，第一子路径矢量所指向的目的节点为该第一出口子节点。
具体的，第一网络节点确定该第一报文的下一跳节点为该第一出口子节点，第一网络节点可以查找从该第一网络节点到达该第一出口子节点的第一子路径矢量。第一网络节点可以通过以下两种可能的实现方式确定该第一子路径矢量。
实现方式一：第一网络节点根据子路径矢量映射关系确定第三端口对应的第一子路径矢量。
其中，该子路径矢量映射关系用于指示第三端口与第一子路径矢量之间的映射关系。该子路径矢量映射关系包括第一虚拟节点的外部端口与路径矢量之间的映射关系。
例如，第一网络节点为虚拟节点4的子节点m，若虚拟节点4的外部端口包括子节点m的端口1和子节点q的端口2，则该子路径矢量映射关系可以通过表5表示：
表5
外部端口 子路径矢量
子节点q的端口2 子路径矢量1
由表5可知，子节点q的端口2对应子路径矢量1。如图4A所示，第三路径矢量为[2,3]，子路径矢量1包括第二转发路径上的节点用于输出的端口的端口分量，如图4A所示，第二转发路径为m→o→r→q。即第一子路径矢量1Sub-PV＝{2,3,2,3}，
实现方式一：第一网络节点确定用于从该第一网络节点向第一出口子节点发送该第一报文的默认子路径矢量。
其中，该默认子路径矢量是预先配置的。例如，如图4A所示，第一网络节点为虚拟节点4中的子节点m，默认子路径矢量包括第二转发路径上的节点用于输出的端口的端口分量，如图4A所示，第二转发路径为m→o→r→q。即默认子路径矢量Sub-PV＝{2,3,2,3}，
步骤3：第一网络节点根据第一子路径矢量和第三路径矢量发送第一报文。
下面结合步骤a至步骤c介绍步骤3。
步骤a：第一网络节点确定第一子路径矢量的第一个端口分量对应第一网络节点的第二端口。
步骤a与前述步骤204a类似，具体请参阅步骤204a的相关介绍，这里不再赘述。
例如，如图4A所示，第一子路径矢量Sub-PV＝{2,3,2,3}，第一子路径矢量的第一个端口分量为2，那么子节点m确定该第一个端口分量对应子节点m的端口2。
步骤b：第一网络节点删除第一子路径矢量的第一个端口分量，得到第二子路径矢量。
例如，如图4A所示，子节点m将第一子路径矢量Sub-PV＝{2,3,2,3}中的第一个端口分量2删除，得到第二子路径矢量Sub-PV＝{3,2,3}。
步骤c：第一网络节点通过第一网络节点的第二端口发送包含第二子路径矢量和第三路径矢量的第一报文。
可选的，该第一报文为IP报文或以太网报文。
为了兼容IP报文的封装格式，第一网络节点将第二子路径矢量sub-PV放在IP报文的目标地址(destination address)域时，第一网络节点将原本放置在IP报文的目标地址(destination address)域中的第三路径矢量搬移到IP报文的子报文头中。
例如，如图4A所示，子节点m通过子节点m的端口2发送第一报文，该第一报文携带第二子路径矢量Sub-PV＝{3,2,3}和第三路径矢量[2,3]。
本申请实施例中，第二转发路径上除第一网络节点之外的其他节点在转发第一报文的过程与第一网络节点执行步骤a至步骤c的过程类似。例如，如图4A所示，子节点o接收到第一报文后，子节点o将Sub-PV＝{3,2,3}中的第一个端口分量3删除，得到Sub-PV＝{2,3}，子节点o通过子节点o的端口3发送包含Sub-PV＝{2,3}和PV＝[2,3]的第一报文。
上述描述了第一虚拟节点内部的路由场景，下面结合图4B说明第一转发路径上的节点根据第三路径矢量转发第一报文的过程。例如，业务节点A向虚拟节点1的子节点h发送该包含PV＝[2,2,3]的第一报文。子节点h按照前述第一网络节点步骤a至步骤c的转发过程转发。虚拟节点1的子节点l接收到该第一报文后，子节点l将该PV＝[2,2,3]中的第一 个端口分量“1删除”，得到PV＝[2,3]，再向虚拟节点4的子节点m发送包含PV＝[2,3]的第一报文。该第一转发路径上的其他节点的转发类似，具体可以参阅图4B中的示例。
可选的，当第一虚拟节点的第一出口子节点发送该第一报文时，第一出口子节点删除IP报文的目标地址(destination address)域的子路径矢量Sub-PV，可以将IP报文的子报文头中的第三路径矢量搬移到IP报文的目标地址(destination address)域中。
由此可知，本实施例中通过引入虚拟节点的方案，通过虚拟节点聚合一个局部网络中的多个节点。从而减少路径矢量的长度，减少节点设备计算路径矢量的计算量。例如，如图4A所示，如果在未引入虚拟节点的方案，用于业务节点A向业务节点C发送报文的路径矢量为{1,2,3,2,2,3,2,3,2,2}。而引入虚拟节点的方案，用于业务节点A向业务节点C发送报文的路径矢量为{1,2,2,3}。由此明显可知，路径矢量的长度变短，这样可以降低业务节点A计算路径矢量的计算量，提高数据传输效率。并且，由于路径矢量不需要统一分配，不存在IP地址枯竭的问题，能适应各种类型的网络。
下面结合图4C介绍步骤2中的子路径矢量映射关系的的生成过程。请参阅图4C，该方法包括：
401、第一网络节点通过路由协议或相应的协议获取第四端口信息。
其中，第四端口信息包括第一虚拟节点包括的子节点的端口的端口信息。
例如，如图4A所示，子节点m通过路由协议接收虚拟节点4包括子节点o、子节点p、子节点q、子节点s和子节点r扩散的端口的端口信息。其中，子节点q作为第一虚拟节点的外部端口，子节点q通过路由协议扩散子节点q的端口2作为第一虚拟节点的外部端口的端口信息，这样子节点m能够确定虚拟节点4中的外部端口的端口信息。
402、第一网络节点根据第四端口信息生成一个或多个转发路径。
其中，该一个或多个转发路径包括第二转发路径。
第一网络节点根据第四端口信息生成以第一网络节点为起始节点和第一虚拟节点的外部端口所在的子节点为目的节点的一个或多个转发路径。可选的，第一网络节点通过最短路径算法生成该一个或多个转发路径。
例如，如图4A所示，子节点m确定子节点q的端口2为虚拟节点4的外部端口，子节点m生成子节点m至子节点q的最短路径，即如图4A所示的虚拟节点4中实线箭头部分的转发路径m→o→r→q。
403、第一网络节点根据该一个或多个转发路径和第一虚拟节点的外部端口的端口信息确定一个或多个路径矢量。
其中，该外部端口的端口信息包括第一虚拟节点的第三端口。
下面以第一网络节点生成第一子路径矢量为例说明步骤403。该第一子路径矢量包括第二转发路径上用于输出的端口的端口信息。具体的，步骤403包括步骤403a至步骤403b。
步骤403a：第一网络节点根据第一出口子节点的第三端口确定第二转发路径。
其中，第二转发路径的起始子节点为第一入口子节点，第二转发路径的目的子节点为第一出口子节点。这里的第一入口子节点和第一出口子节点是第一报文的流向来说的。第一出口子节点的第三端口属于该虚拟节点4的外部端口。
由上述步骤402可知，该一个或多个转发路径的起始节点为该第一网络节点，目的节点为第一虚拟节点的外部端口所在的子节点。由于第一出口子节点的第三端口为该第一虚拟节点的外部端口，所以第一网络节点可以从该一个或多个转发路径查找目的节点为该第一出口子节点的第二转发路径。
步骤403b：第一网络节点根据第三端口信息生成第一子路径矢量。
其中，第三端口信息为第二转发路径上的子节点用于输出的端口的端口信息。
具体的，第三端口信息包括一个或多个端口分量，而端口分量的表示形式可以参阅前述图2A所示的步骤202中的相关介绍，这里不再赘述。
例如，如图4A所示，第二转发路径为m→o→r→q，第一子路径矢量为{2,3,2,3}。
404、第一网络节点分别建立该一个或多个子路径矢量与该第一虚拟节点的外部端口之间的映射关系。得到子路径矢量映射关系。
其中，子路径矢量映射关系包括第三端口与第一子路径矢量之间的映射关系。
下面以第三端口与第一子路径矢量之间的映射关系为例介绍步骤404。
由上述步骤403a至步骤403b可知，第一网络节点通过第三端口确定第二转发路径，再由该第二转发路径上的节点用于输出的端口的端口信息生成第二转发路径。由此可知，第三端口与第一子路径矢量之间具有映射关系，第一网络节点可以建立第三端口与第一子路径矢量之间的映射关系。
为了保证转发路径的负载均衡，本申请实施例还提供以下技术方案，下面通过图5A所示的实施例作介绍。请参阅图5A，该方法包括：
501、第一业务节点根据第一业务信息确定多个路径矢量。
其中，该多个路径矢量与多个转发路径一一对应，每个路径矢量包括对应的转发路径上的一个或多个节点的端口的端口信息。路径矢量和第一业务信息的相关介绍请参阅前述图2A所示的实施例中的相关说明，这里不再赘述。
可选的，第一业务节点根据第一路径矢量映射关系确定第一业务信息对应多个路径矢量。
下面以第一业务信息为第一业务标识，且第一业务标识为Service ID1为例介绍步骤501。下面通过表6示出该第一路径矢量映射关系，请参阅表6：
表6
Service ID 路径矢量
Service ID1 路径矢量1
Service ID1 路径矢量2
Service ID2 路径矢量3
由表6可知，Service ID1对应路径矢量1和路径矢量2。如图5B所示，路径矢量1对应转发路径1，转发路径1为A→a→b→d→C。路径矢量2对应转发路径2，转发路径2为A→a→c→e→f→D。
502、第一业务节点获取多份业务数据。
其中，该多份业务数据分别携带第一业务信息。
可选的，该多份业务数据为应用层请求或应用层任务。
示例一：如图5B所示，第一业务节点为终端设备，该终端设备通过app请求“王者荣耀”的游戏服务请求。由表5可知第一业务信息对应路径矢量1和路径矢量2，而路径矢量1对应转发路径1，路径矢量2对应转发路径2。该终端设备复制该游戏服务请求，得到两个游戏服务请求。
示例二：该终端设备在第一时刻通过app请求“王者荣耀”的游戏服务请求，而在第二时刻通过app请求“爱奇艺”的视频服务请求。那么该多份业务数据可以理解为第一业务节点在不同时刻产生的应用层请求。
503、第一业务节点分别将该多份业务数据映射至多个路径矢量中对应的路径矢量。
其中，映射用于多个转发路径的负载均衡。
具体的，第一业务节点可以按照负载均衡的规则将该多份数据映射至多个路径矢量中对应的路径矢量。
结合步骤502的示例1可知，请参阅图5B，终端设备复制该游戏服务请求，得到两个游戏服务请求。终端设备将该两个游戏服务请求分别映射至路径矢量1和路径矢量2，这样终端设备可以同时在转发路径1和转发路径2分别发送该游戏服务请求。那么终端设备可以根据业务节点C和业务节点D的反馈速度，优先选择由反馈速度较快的业务节点提供该游戏服务，以提高网络请求速度，提高用户体验。
结合步骤502的示例二可知，请参阅图5B，终端设备在第一时刻通过app请求“王者荣耀”的游戏服务请求，终端设备确定转发路径1的负载小于转发路径2，则终端设备可以将该游戏服务请求映射至路径矢量1，即通过转发路径1发送该游戏服务请求，以减小转发路径2的负载，提高网络传输速度。而终端设备在第二时刻通过app请求“爱奇艺”的视频服务请求，终端设备确定转发路径1的负载大于转发路径2，则终端设备可以将该视频服务请求映射至路径矢量2，即通过转发路径2发送该视频服务请求，以减小转发路径2的负载，提升网络传输速度。
本实施例中，第一业务节点获取多份业务数据，第一业务节点按照负载均衡的规则将多份业务数据映射至多个路径矢量中对应的路径矢量，这样有利于多个路径矢量对应的多个转发路径的负载均衡，提高数据传输效率，提升网络传输性能。
由上述图3A所示的实施例可知，业务节点收集第二端口信息和第二业务标识生成一个或多个转发路径，再通过该一个或多个转发路径和第二业务标识生成一个或多个路径矢量，以便于报文转发。由于业务节点接入第一网络，第一业务节点需要生成到达该第一网络的其他业务节点的路径矢量，这样对业务节点的性能要求较高，且计算路径矢量的复杂度较大。
为了解决上述问题，本申请实施例提供了在网络中设立分级网关设备的方案。而在网络中设立分级网关设备的方案中，包括两种可能的实现方式，下面通过图6A所示的实施例和图7所示的实施例分别作介绍。
请参阅图6A，图6A为本申请实施例报文处理方法的另一个实施例示意图。在图6A中，该方法包括：
601、第一业务节点获取第一业务数据。
步骤601与前述图2A所示的实施例中的步骤201类似，具体请参阅前述图2A所示的实施例中的步骤201的相关说明，这里不再赘述。
602、第一业务节点判断是否存在第一业务信息对应的第一路径矢量，若是，则执行步骤603；若否，则执行步骤606。
其中，第一业务节点归属第一网络，第一网络为家庭数据中心网络或城域网等。第一业务信息的相关介绍请参阅前述图2A所示的步骤201。
具体的，第一业务节点可以按照前述图3A所示的实施例生成用于第一业务节点向第一网络包括的业务节点发送报文的一个或多个路径矢量，且每个路径矢量都有对应的业务信息。
本实施例中，将网络系统划分为三部分网络，每部分网络都设立有网关设备。第一业务节点归属第一网络，则第一业务节点只生成用于第一业务节点向第一网络包括的业务节点发送报文的一个或多个路径矢量。因此，当第一业务信息不属于该第一网络包括的业务节点所支持的业务的业务信息时，第一业务节点从该一个或多个路径矢量查找不到第一业务信息对应的第一路径矢量。
例如，如图6B所示，网络系统包括家庭数据中心网络和城域网。网络系统还包括广域网(图6B中未示出)。家庭数据中心网络的网关设备为服务器(server)，城域网的网关设备为宽带网络网关(broadband network gateway，BNG)。服务器为连接家庭数据中心网络和城域网的网关设备，用于代理家庭数据中心网络包括的节点与城域网包括的节点进行通信。BNG用于连接城域网与广域网，用于代理城域网包括的节点与广域网包括的节点进行通信。
如图6B所示，家庭数据中心网络包括业务节点A和业务节点B。业务节点B位于家庭数据中心网络，业务节点B只生成用于业务节点B向业务节点A发送报文的路径矢量。该路径矢量与该业务节点A所支持的业务的业务标识对应。由图6B可知，业务节点B判断该路径矢量中是否为第一业务标识对应的第一路径矢量；如果不存在，则执行步骤606；如果存在，则执行步骤603。
可选的，第一业务节点判断第一路径矢量映射关系是否存在第一业务信息对应的第一路径矢量。其中，该第一路径矢量映射关系的相关说明请参阅前述图2A所示的实施例中的步骤202和前述图3A所示的实施例的相关介绍，这里不再赘述。
603、第一业务节点确定第一业务信息对应的第一路径矢量。
604、第一业务节点生成包含第一路径矢量的第一报文。
步骤603至步骤604与前述图2A所示的实施例中的步骤202至步骤203类似，具体请参阅前述图2A所示的实施例中的步骤202至步骤203的相关说明，这里不再赘述。
605、第一业务节点根据第一路径矢量发送第一报文。
步骤605与前述图2A所示的实施例中的步骤204和步骤205的操作流程类似，具体请参阅前述图2A所示的实施例中的步骤204和步骤205的相关说明，这里不再赘述。
606、第一业务节点确定第一默认路径矢量。
其中，第一默认路径矢量所指向的目的节点为代理节点，该代理节点为连接第一网络和第二网络的网关设备，用于代理第一业务节点与第三业务节点进行通信的节点。第三业务节点用于为第一业务节点提供第一业务数据所对应的业务服务。
第一网络为家庭数据中心网络，第二网络为城域网；或者，第一网络为城域网，第二网络为广域网。
代理节点为服务器、BNG或宽带接入服务器(broadband remote access server,BRAS Server)。
本实施例中，第一业务节点从一个或多个路径矢量查找不到第一业务信息对应的第一路径矢量时，第一业务节点通过第一默认路径矢量转发报文。且第一默认路径矢量所指向的目的节点为第一网络的代理节点。这样，由该第一网络的代理节点对该报文作进一步的处理并转发。
可选的，第一默认路径矢量包括第六转发路径上的用于输出的节点的端口的端口信息。而该端口信息包括一个或多个端口分量。关于端口分量的相关说明请参阅前述图2A所示的实施例中步骤202的相关介绍，这里不再赘述。
例如，如图6B所示，第六转发路径为B→a→服务器，第一默认路径矢量为[1,101]。第三业务节点为业务节点C。
607、第一业务节点生成包含第一默认路径矢量的第一报文。
步骤607与前述图2A所示的实施例中的步骤203类似，具体请参阅前述图2A所示的实施例中的步骤203的相关介绍，这里不再赘述。
608、第一业务节点根据第一默认路径矢量发送第一报文。
步骤608与前述图2A所示的实施例中的步骤204和步骤205的操作流程类似，具体请参阅前述图2A所示的实施例中的步骤204和步骤205的相关说明，这里不再赘述。
609、代理节点接收第一业务节点的第一报文。
步骤608中第一业务节点根据第一默认路径发送第一报文，第一默认路径矢量所指向的目的节点为代理节点，那么代理节点可以接收该第一业务节点的第一报文。
例如，如图6B所示，业务节点B通过端口1发送第一报文，网络节点a通过网络节点a的端口4接收业务节点B发送的第一报文，并通过节点a的端口5向服务器(代理节点)发送该第一报文。
本实施例中，第一业务节点查找不到第一业务信息对应的第一路径矢量时，第一业务节点通过第一默认路径矢量向第一网络的代理节点发送报文，由该代理节点帮忙处理该报文并转发该报文，以实现报文的传输。
因此，第一网络的代理节点通过路由协议或相应的协议获取第二网络包括的节点的端口的端口信息和第二网络包括的业务的业务信息，并根据该端口信息和业务信息生成一个或多个路径矢量，再建立该业务信息与该一个或多个路径矢量之间的映射关系。这样，代理节点接收到第一业务节点的报文时，当第一业务信息对应的是用于代理节点向第二网络包括的业务节点发送报文的路径矢量时，代理节点才能够通过该路径矢量将该报文转发至第二网络的相应节点上，以实现对该报文的传输。
610、代理节点根据第一业务信息确定第八路径矢量。
步骤610与前述图2A所示的实施例中的步骤202类似，具体请参阅前述图2A所示的实施例中的步骤202的相关说明，这里不再赘述。
可选的，代理节点按照前述图3A所示的实施例中的方式生成用于代理节点向第二网络的业务节点发送报文的一个或多个路径矢量，并建立路径映射关系。可选的，代理节点还用于屏蔽该第二网络包括的节点扩散的端口信息和业务信息，以避免第一网络包括的节点接收第二网络包括的节点的端口信息和业务信息。
例如，如图6B所示，家庭数据中心网络中的服务器作为第一级矢量路由网关设备，用于接收城域网包括的节点的端口信息和城域网包括的业务节点所支持的业务标识，并根据该端口信息和业务标识生成一个或多个路径矢量，并建立路径矢量映射关系。具体的建立过程与前述图3A所示的实施例类似，这里不再赘述。服务器从该一个或多个路径矢量中确定第一业务信息对应的第八路径矢量。
需要说明的是，若服务器查找不到该第一业务标识对应的第八路径矢量，如第一业务数据所对应的业务服务由业务节点D提供，服务器只生成了用于服务器向城域网的业务节点发送报文的路径矢量。服务器可以向该城域网的BNG发送该第一报文，再由该城域网的BNG向业务节点D发送该第一报文。
再举例说明，如图6B所示，BNG作为第二级矢量路由网关设备，用于接收广域网包括的节点的端口信息和广域网包括的业务节点所支持的业务标识，并根据该端口信息和业务标识生成一个或多个路径矢量，并建立路径映射关系。具体的建立过程与前述图3A所示的实施例类似，这里不再赘述。BNG从该一个或多个路径矢量中确定第一业务信息对应的第八路径矢量。
611、代理节点生成包含第六路径矢量的第一报文。
步骤611与前述图2A所示的实施例中的步骤203类似，具体请参阅前述图2A所示的实施例中的步骤203的相关说明，这里不再赘述。
612、代理节点根据第六路径矢量发送第一报文。
步骤612与前述图2A所示的实施例中的步骤204和步骤205的操作流程类似，具体请参阅前述图2A所示的实施例中的步骤204和步骤205的相关说明，这里不再赘述。
613、第三业务节点接收第一业务节点的第一报文。
例如，如图6B所示，服务器通过第六路径矢量发送该第一报文，第六转发路径上的最后一个网络节点为网络节点f，通过该网络节点f向业务节点C发送该第一报文。

下面示出第六路径矢量映射关系的生成过程。本实施例还包括步骤615a至步骤615d。

其中，第九端口信息包括网络系统的节点的端口的端口信息，第三信源信息包括网络系统的包括的业务节点的信源信息。网络系统包括多部分网络，例如，如图6B所示，网络系统包括家庭数据中心网络、城域网和广域网等。第三业务节点获取网络系统包括的节点的端口的端口信息和网络系统包括的业务节点的信源名称。
步骤615b：第三业务节点根据第九端口信息和第三信源信息生成一个或多个转发路径。
例如，如图6B所示，业务节点C获取网络系统包括的节点的端口的端口信息和网络系统包括的业务节点的信源名称；然后，业务节点C根据网络系统包括的节点的端口的端口信息和网络系统包括的业务节点的信源名称生成以业务节点C为起始节点的一个或多个转发路径。可选的，业务节点C通过最短路径算法生成该一个或多个转发路径。
如图6B中，业务节点A的信源信息为信源名称1，业务节点C生成业务节点C至该业务节点A的最短转发路径。
步骤615c：第三业务节点根据该一个或多个转发路径和第三信源信息确定一个或多个路径矢量。
其中，第三信源信息包括第一信源信息，一个或多个转发路径包括第七转发路径。
下面以第三业务节点生成第九路径矢量为例说明步骤615c。步骤615c具体包括步骤1至步骤2。
步骤1：第三业务节点根据第一信源信息确定第七转发路径。
其中，第七转发路径的起始节点为第三业务节点，第七转发路径的目的节点为第一业务节点，第一业务节点的信源信息为第一信源信息。
例如，如图6B所示，业务节点A为第一业务节点，业务节点C确定业务节点A的信源信息为第一信源信息。业务节点C从一个或多个转发路径中查找目的节点为该业务节点A的第七转发路径。
步骤2：第三业务节点根据该第七转发路径上用于输出的端口的端口信息生成第九路径矢量。
具体的，用于输出的端口的端口信息包括一个或多个端口分量，而端口分量的表示形式可以参阅前述图2A所示的步骤202中的相关介绍，这里不再赘述。
步骤615d：第三业务节点分别建立该第三信源信息和该一个或多个转发路径之间的映射关系，得到第六路径映射关系。
其中，第六路径矢量映射关系包括第一信源信息与九路径矢量之间的映射关系。
下面以第三业务节点建立第一信源信息与第九路径矢量之间的映射关系为例介绍步骤615d。由上述步骤615a至步骤615c可知，第三业务节点通过第一信源信息确定第七转发 路径，再由第七转发路径上的节点用于输出的端口的端口信息生成该第九路径矢量。由此可知，第一信源信息与该第九路径矢量之间具有映射关系，第三业务节点可以建立该第一信源信息与该第九路径矢量之间的映射关系。
616、第三业务节点生成包含第九路径矢量的第五报文。
617、若第九路径矢量包括第三业务节点的端口信息，则第三业务节点发送包含第十路径矢量的第五报文。

可选的，第三业务节点也可以通过类似第一业务节点的报文转发方式转发报文，具体为，第三业务节点通过默认路径矢量向第二网络的代理节点发送第五报文，再由第二网络的代理节点向第一业务节点发送第五报文。具体的操作流程与前述图6A所示的实施例中的步骤606至步骤608类似，这里不再赘述。
本申请实施例中，在网络系统中设立第一网络的代理节点，当第一业务节点查找不到第一业务信息对应的第一路径矢量时，第一业务节点通过第一默认路径矢量向代理节点发送该第一报文；再由该代理节点根据该第一业务信息确定第八路径矢量，并根据第八路径矢量向第二网络的第三业务节点发送第一报文，从而实现报文的传输。由此可知，第一业务节点只需要计算用于该第一业务节点到达该第一网络中的业务节点的路径矢量，如果查找不到对应的路径矢量，就通过默认路径矢量向代理节点发送报文，再由代理节点进一步处理该报文并转发该报文。这样既能够完成报文的传输，又能够减小第一业务节点计算路径矢量的计算量，降低对第一业务节点的性能要求。

并且，代理节点生成的一个或多个路径矢量中包括用于代理节点向第一网络包括的业务节点发送报文的路径矢量，还包括用于代理节点向第二网络包括的业务节点发送报文的路径矢量。即该第二路径矢量映射关系包括第一网络包括的业务节点的业务标识与路径矢量之间的映射关系和第二网络包括的业务节点的业务标识与路径矢量之间的映射关系。
例如，如图6B所示，家庭数据中心网络中的服务器接收家庭数据中心网络包括的节点的端口信息和家庭数据中心网络包括的业务节点所支持的业务的业务标识，并根据该端口信息和业务标识生成一个或多个路径矢量。家庭数据中心网络中的服务器作为第一级矢量路由网关设备，用于接收城域网包括的节点的端口信息和城域网包括的业务节点所支持的业务标识，并根据该端口信息和业务标识生成一个或多个路径矢量。再综合前述生成所有 路径矢量和代理节点获取到的所有业务标识建立该第二路径映射关系。
