Description

用于报文传输的方法和节点
本申请要求于2020年5月9日提交中国国家知识产权局、申请号为202010387411.6、申请名称为“用于报文传输的方法和节点”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
本申请涉及通信领域，更具体地，涉及一种用于报文传输的方法和节点。
背景技术
随着网络规模的增长，电信系统越来越复杂，从而带来了诸多的挑战，包括新增业务的开发上线、系统的运维和资源利用率等。为了应对这些挑战，电信系统利用了信息技术(information technology，IT)业界的虚拟化技术及云技术。
网络功能虚拟化(network functions virtualization，NFV)技术可以简单地理解为将电信网络中使用的各个网元的功能从目前的专用硬件平台迁移至通用的商用货架产品服务器上。通过NFV技术将电信网络中使用的各个网元转变称为独立的应用，可以灵活部署在基于标准的服务器、存储以及交换机等其他设备构建的统一基础设施平台上，并通过虚拟化技术，对基础设施硬件设备资源池化及虚拟化，对上层应用提供虚拟资源，实现应用、硬件解耦，使得每一个应用能够快速增加虚拟资源以实现快速扩展系统容量的目的，或者能够快速减少虚拟资源以实现收缩系统容量的目的，大大提升网络的弹性。采用通用的商业现货(COTS)服务器组成共享的资源池，新开发的业务，不需要单独部署硬件设备，大大缩短新业务上线时间。
电信系统上云最为彻底的方式便是把二层通讯改造为三层通讯。传统方案，设备之间通过将二层报文封装在标准的互联网协议(internet protocol，IP)/用户数据报协议(user datagram protocol，UDP)报文中，以实现私有二层报文的交互。例如，构建一个二层互通的虚拟可扩展局域网(virtual expandable LAN，VXLAN)网络，需要每个VXLAN的节点知道其余所有VXLAN节点的信息，即所有VXLAN节点中容器的IP地址和媒体访问控制(media access control，MAC)地址。而VXLAN网络中VXLAN节点中的容器之间的IP地址和MAC地址的同步，需要网络中部署VXLAN控制器。也就是说，传统方案中，电信系统需要引入额外的控制器，使得管理复杂度较高。

应用管理模块可以根据第三关联关系和第一容器的MAC地址找到节点第二节点的IP地址，并通过节点的IP地址向节点内的容器转发报文。也就是说，本申请实施例中节点可以实现不需要引入额外的控制器获知即将发送报文的容器所属的节点，从而降低了系统的管理复杂度。
在一些可能的实现方式中，该第一容器的MAC地址包括至少一个字节，该第二节点的IP地址包括至少一个字节，该第三关联关系为该第一容器的MAC地址中的部分字节的取值与该第二节点的IP地址中的部分字节的取值相同。
该第三关联关系可以是部分字节取值相同，即通过简单的方式实现容器的IP地址和节点的IP地址的关联，从而更进一步降低系统的管理复杂度。
在一些可能的实现方式中，所述第一容器的MAC地址包括六个字节，所述第二节点的IP地址包括四个字节，该第三关联关系为所述第一容器的MAC地址中的第五字节的取值与所述第二节点的IP地址中的第三个字节的取值相同，所述第一容器的MAC地址中的第六字节的取值与所述第二节点的IP地址中的第四个字节的取值相同。

在该第一节点的操作系统中没有存储该第一容器的第一地址对应的第二地址的情况下，第二容器可以向该第一节点中的应用管理模块发送请求信息，以请求该第一地址对应的第二地址，从而能够实现向第一容器发送报文。也就是说，第二容器在存在需求的情况下才向应用管理模块请求第一地址对应的第二地址，这样可以避免在操作系统中存储太多不必要的地址，从而节省了操作系统的存储空间。此外，相对于传统方案引入额外的控制器来获得本节点之外的节点中的容器的地址，本申请实施例降低了系统的管理复杂度。
在一些可能的实现方式中，在所述第一地址为MAC地址，所述第二地址为IP地址的情况下，所述方法还包括：所述第一容器从所述操作系统中检测所述第一容器的MAC地址对应的第二节点的IP地址；其中，所述第二容器根据所述第一容器的第一地址和所述第一容器的第二地址，向所述第一容器发送报文包括：所述第二容器向所述第二节点的IP地址对应的第二节点发送所述报文，所述第二节点用于向所述第一容器转发所述报文。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
图1示出了本申请实施例的通信系统。该通信系统中可以包括至少两个节点，例如，图1所示的节点1和节点2。以节点1为例进行说明，节点1中可以包括应用管理模块和容器管理模块以及至少一个容器(例如，容器1、容器2和容器3)。其中，应用管理模块用于创建接口以及分配业务的IP地址和MAC地址，容器管理模块用于创建容器。
可以理解的是，该应用管理模块可以是VXLAN应用管理模块。在该应用管理模块为VXLAN应用管理模块的情况下，对应的接口可以是VXLAN接口。
传统方案中，设备之间通过将二层报文封装在标准的IP/UDP报文中，以实现私有二层报文的交互。如图2示出了VXLAN报文的结构。例如，构建一个二层互通的虚拟可扩展局域网(virtual expandable LAN，VXLAN)网络，需要每个VXLAN的节点知道其余所有VXLAN节点的信息，即所有VXLAN节点中容器的IP地址和媒体访问控制(media access control，MAC)地址。而VXLAN网络中VXLAN节点中的容器之间的IP地址和MAC地址的同步，需要网络中部署VXLAN控制器。也就是说，传统方案中，电信系统需要引入额外的控制器，使得管理复杂度较高。
图3示出了本申请实施例的用于报文传输的方法的示意性流程图。
应理解，本申请实施例可以应用于图1所示的通信系统中。
301，第一节点中的第二容器可以向应用管理模块发送请求信息，该请求信息用于请求第二节点中的第一容器的第一地址对应的第二地址，该第一地址为IP地址，该第二地址为MAC地址，或该第一地址为MAC地址，该第二地址为IP地址。
具体地，第一节点中的第二容器想要向第二节点中的第一容器发送报文，若只知道第一容器的第一地址(例如，该第一节点的操作系统中只存储该第一容器的第一地址)，则可以向该第一节点中的应用管理模块发送请求信息，以请求该第一地址对应的第二地址。其中，若第一地址是IP地址，则第二地址可以是MAC地址；若第一地址是MAC地址，则第二地址可以是IP地址。也就是说，第二容器需要获得第一容器的IP地址和MAC地址才能实现向第一容器发送报文。
可以理解的是，该第一节点中除包括该第二容器，还可以包括其他容器，本申请对此不进行限定。类似地，该第二节点中除包括该第一容器，还可以包括其他容器，本申请对此不进行限定。
302，第一节点中的应用管理模块根据该第一容器的第一地址和第一关联关系，确定该第 一容器的第二地址，该第一关联关系为该第二节点中容器的第一地址和第二地址之间的关联关系。
具体地，应用管理模块可以存储第二节点中容器的第一地址和第二地址之间的第一关联关系。也就是说，应用管理模块可以根据该第一地址和该第一关联关系得到第二地址，例如，直接获得，或者间接推导得到。
可以理解的是，该第一关联关系可以包括第二节点中的某一个容器(例如，第一容器)的第一地址与该第一容器的第二地址具有关联关系，也可以包括第二节点中的一个或多个容器中的每个容器的第一地址与第二地址具有关联关系。例如，该第一关联关系包括第一容器的IP地址与第一容器的MAC地址的对应关系。
还可以理解的是，该第一关联关系也可以是看作是一种预先制定的规则。应该管理模块可以根据该第一地址和该规则推导得到该第二地址。
可选地，在第一容器的MAC地址包括至少一个字节，该第一容器的IP地址包括至少一个字节的情况下，该第一关联关系为该第一容器的MAC地址中的部分字节的取值与该第一容器的IP地址中的部分字节的取值相同。
具体地，MAC地址中的与IP地址中取值相同的部分字节为多个的情况下，该多个字节可以是连续的，也可以是不连续的，本申请对此不进行限定。也就是说，第一容器的MAC地址中的部分字节中的每个字节的取值可以分别与第一容器的IP地址的多个字节中某个字节的取值相同，也可以是该第一容器的MAC地址中的部分字节的整体取值与该第一器的IP地址的多个字节的整体取值相同。
可以理解的是，一个字节可以包括一个或多个比特位。其中，取值相同的不同字节包括的比特位可以相同，也可以不同，本申请对此不进行限定。
还可以理解的是，本申请实施例可以应用于(互联网协议第4版，IPv4)场景中，也可以引用于IPv6场景中，本申请对此不进行限定。
还可以理解的是，该第一关联关系可以是临时生成的，也可以是已知存储在应用管理模块中的，本申请对此不进行限定。
可选地，在第一容器的MAC地址包括六个字节，第一容器的IP地址包括四个字节的情况下，该第一关联关系为该第一容器的MAC地址中的第四个字节的取值与该第一容器的IP地址中的第二个字节的取值相同，该第一容器的MAC地址中的第五个字节的取值与该第一容器的IP地址中的第三个字节的取值相同，以及该第一容器的MAC地址中的第六个字节的取值与该第一容器的IP地址中的第四个字节的取值相同。
具体地，若MAC地址包括六个字节，则MAC地址的结构可以为“0a:0a:0a:业务IP第4字节:业务IP第5字节:业务IP第6字节”。
其中，业务IP地址的第二字节与MAC地址的第四字节的进制可以不同。例如，IP地址为“10.101.10.100”对应的MAC地址为“0a:0a:0a:65:0a:64”(下划线上的数字具有对应关系，倾斜字体的数字也具有对应关系)。即IP地址的字节通过二进制表示，MAC地址的字节通过16进制表示。
需要说明的是，除具有关联关系的字节之外的字节可以是预先设定的，例如，IP地址中的第一个字节设定为“10”，MAC地址的前三个字节设定为“0a:0a:0a”，或者还可以是其他预先设定的取值，本申请对此不进行限定。
可选地，在第一地址为IP地址的情况下，该应用管理模块还可以根据该第一容器的IP地址和第二关联关系确定该第二节点的IP地址，并将该第二节点的IP地址写入操作系统中。其中，该第二节点用于向该第一容器转发报文，该第二关联关系为节点的IP地址与第二节点中容器的IP地址之间的关联关系。
具体地，在第一地址为IP地址，第二地址为MAC地址的情况下，若第一节点无法直接找到第一容器(即没有到该第一容器的路由信息)，则第二容器需要先找到包括该第一容器的第二节点，再由第二节点将报文转发给第一容器。例如，第二容器向应用管理模块发送3层信息缺失(layer3miss，L3MISS)信息，应用管理模块在检测到该L3MISS信息，得知IP地址缺少路由信息。
可以理解的是，该第二关联关系可以包括第二节点中的某一个容器(例如，第一容器)与第二节点的IP地址的对应关系，也可以是包括第二节点中的多个容器中的每个容器分别与节点的IP地址的关联关系，本申请对此不进行限定。
可选地，该第一容器的IP地址包括至少一个字节，该第二节点的IP地址包括至少一个字节，该第二关联关系为该第一容器的IP地址中的部分字节的取值与该第二节点的IP地址中的部分字节的取值相同。
具体地，所述第一容器的IP地址包括四个字节，所述第二节点的IP地址包括四个字节，该第二关联关系为所述第一容器的IP地址中的第二字节的取值与所述第二节点的IP地址中的第三个字节的取值相同，所述第一容器的IP地址中的第三字节的取值与所述第二节点的IP地址中的第四个字节的取值相同。
例如，若该第一容器的IP地址为“10.101.10.100”，则第二节点的IP地址为“172.16.101.10”。
需要说明的是，节点的IP地址的前两个字节可以是预先设定的，例如，节点的IP地址的前两个字节为“172.16”。其中，容器的IP地址中的最后一个字节可以是节点内的唯一序号。
可选地，在第一地址为MAC地址的情况下，该应用管理模块还可以根据该第一容器的MAC地址和第三关联关系确定该第二节点的IP地址，并将该第二节点的IP地址写入操作系统中，该第三关联关系为节点的IP地址与第一容器的MAC地址的关联关系。其中，该第二节点用于向该第一容器转发报文。
具体地，若第二容器根据该第一容器的MAC地址无法找到第一容器，则第二容器需要先找到包括该第一容器的第二节点，再由第二节点将报文转发给第一容器。例如，第二容器向应用管理模块发送2层信息缺失(layer 2miss，L2MISS)信息，应用管理模块在检测到该L2MISS信息，得知MAC地址缺少路由信息。
可选地，该第一容器的MAC地址包括至少一个字节，该第二节点的IP地址包括至少一个字节，该第三关联关系为该第一容器的MAC地址中的部分字节的取值与该第二节点的IP地址中的部分字节的取值相同。
具体地，所述第一容器的MAC地址包括六个字节，所述第二节点的IP地址包括四个字节，该第三关联关系为所述第一容器的MAC地址中的第五字节的取值与所述第二节点的IP地址中的第三个字节的取值相同，所述第一容器的MAC地址中的第六字节的取值与所述第二节点的IP地址中的第四个字节的取值相同。
例如，该第一容器的MAC地址为“0a:0a:0a:66:1e:6a”，则对应的第二节点的IP地址为“172.16.102.30”。
可以理解的是，节点的IP地址的前两个字节可以是预先设定的，例如，节点的IP地址的前两个字节为“172.16”。
303，该应用管理模块在操作系统中写入该第二地址，该第二地址为该第一节点中的第二容器传输报文的目的地址。
具体地，应用管理模块可以将第二地址写入操作系统的系统缓存中，例如，该第二地址写入转发数据库(forwarding database，FDB)表。
可以理解的是，应用管理模块可以随操作系统启动而启动，启动后可以检查第一节点的接口是否正确配置。若没有正确配置，则进行接口的配置。例如，该接口为VXLAN接口。
还可以理解的是，该操作系统可以是OS。
还可以理解的是，该应用管理模块也可以主动执行更新第一地址对应的第二地址，例如，定时更新。也就是说，本申请中可以不执行步骤301。
304，该第二容器从操作系统中检测该第一容器的第一地址对应的该第一容器的第二地址。
305，该第二容器根据该第一容器的第二地址和该第一容器的第一地址，向该第一容器发送报文。
第一节点可以存储第二节点中容器的第一地址和第二地址之间的第一关联关系，这样第一节点中的应用管理模块可以根据第二节点中的第一容器的第一地址和该第一关联关系确定出该第一容器的第二地址，进而将第一容器的第二地址写入操作系统中，这样有助于第二容器从操作系统中获得该第一容器的IP地址和MAC地址，从而能够实现向第一容器发送报文，相对于传统方案引入额外的控制器，本申请实施例降低了系统的管理复杂度。
应理解，本申请实施例中的具体的例子只是为了帮助本领域技术人员更好地理解本申请实施例，而非限制本申请实施例的范围。
