具体实施方式
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清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区 别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
为了便于理解本申请实施例，首先说明以下内容。
SRv6是SR-IPv6的简称，是指将分段路由(Segment Routing，SR)应用于IPv6转发平面，即将SR的指令列表(SID列表)封装于IPv6报文中以指导报文按source route(源路径)转发。其中，IPv6头(Header)和段路由头(Segment Routing Header，SRH)可以如图1所示，IPv6Header中的Next Header取值为43表示下层头为路由扩展头(Routing Extension Header)。SRv6数据平面可以采用段路由头(Segment Routing Header，SRH)封装，SRH中封装了分段列表(segment list)信息，每个segment是128bit的IPv6地址。SRv6隧道(tunnel)是相应SID list的管理实体，与其它隧道一样，对业务呈现。SRv6tunnel能够承载二层、三层、多协议标签交换(Multi-Protocol Label Switching，MPLS)、传输控制协议(Transmission Control Protocol，TCP)用户数据包协议(User Datagram Protocol，UDP)等已知的所有类型载荷。
SRv6的SID可理解为路由器的IP地址，SID列表表征整个路由路径的IP地址列表。如图2所示，SRv6的SID可以为128比特(bit)可编程SID，可以包括Locator、功能(Function)(FUNCT)和参数(Arguments)(ARGS)。其中，Locator是SRv6协议体系中的网络节点标识，是网络拓扑中分配给一个网络节点的标识，用于转发数据包到该网络节点。Locator对应的路由会被网络节点通过内部网关协议(Interior Gateway Protocol， IGP)发布到网络中，用于帮助其他设备将数据包转发到发布该Locator的节点网络。在SRv6SID中，Locator长度可变，用于适配不同规模的网络。Locator又可以细分为B和N，B标识SRv6SID块(Block)，一般由运营商分配给某个子网，通常用Prefix来表示，N则是该子网内区分节点的标识。Function(FUNCT)用来表达要执行的转发动作，相当于计算机指令的操作码，在SRv6网络编程中，不同的转发行为(Behavior)由Function部分来描述，如转发数据包到指定链路，或在指定表中查表转发等。Arguments(ARGS)是一个可选字段，是指令在执行时对应的参数，这些参数可能包含数据流、服务或任何其他相关的信息。
在本申请的一些可选实施例中，DHCPv6客户端可以包括但不限于4G/5G设备、小型交换机、路由器等客户侧设备。DHCPv6服务器可以为运营商网络的边缘设备，比如BRAS、SR等。
本申请的一些可选实施例中的SID具体为SRv6的SID，SRv6协议体系中的网络节点标识段(即Locator段)主要用于组成SID，以实现相应路由转发。
为了解决目前无法为客户端设备分配Locator的问题，本申请实施例扩展了DHCPv6，提出了由DHCPv6服务器为DHCPv6客户端动态分配Locator段，该Locator段为SRv6协议体系中的网络节点标识段，从而使得DHCPv6服务器和客户端之间可以正常收发SRv6报文，保证SRv6协议体系运行。
下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的分配标识的方法、装置、通信设备及可读存储介质进行详细地说明。
请参见图3，图3是本申请实施例提供的一种分配标识的方法的流程图，该方法应用于DHCPv6客户端。如图3所示，该方法包括如下步骤：
步骤31：从DHCPv6服务器接收第一报文。
本实施例中，第一报文可以包括第一字段，该第一字段用于指示为 DHCPv6客户端分配的Locator段，该Locator段为SRv6协议体系中的网络节点标识段，主要用于组成SID，以实现相应路由转发。该Locator段可以为一个Locator或者由多个Locator组成。
在本申请的一些可选实施例中，第一报文可选为通告(advertise)报文。
在本申请的一些可选实施例中，第一字段可选为选项(option)字段。比如，第一字段为advertise报文中的专用option字段，比如可以表示为option BB。
在本申请的一些实施例中，上述的第一字段还可以指示相应Locator的其他需要的配置参数，比如Locator值/长度、Block长度、Node长度等。
在本申请实施例中，可以由DHCPv6客户端从DHCPv6服务器接收第一报文，该第一报文包括第一字段，第一字段用于指示为DHCPv6客户端分配的Locator段，该Locator段为SRv6协议体系中的网络节点标识段。由此，可以扩展DHCPv6，由DHCPv6服务器为DHCPv6客户端分配Locator段，从而使得DHCPv6服务器和客户端之间可以正常收发SRv6报文，保证SRv6协议体系运行。进一步的，还可以使得SRv6协议体系不仅覆盖运营商骨干网设备，还可以覆盖骨干网设备和边缘设备。
在本申请的可选实施例中，上述从DHCPv6服务器接收第一报文之前，DHCPv6客户端可以向DHCPv6服务器发送第二报文，该第二报文包括第二字段，第二字段用于请求DHCPv6服务器为DHCPv6客户端分配Locator段，以基于此请求来由DHCPv6服务器为DHCPv6客户端分配Locator段。
在本申请的一些可选实施例中，第二报文可选为寻求(solicit)报文。
在本申请的一些可选实施例中，第二字段可选为选项(option)字段。比如，第二字段为solicit报文中的专用option字段，比如可以表示为option AA。
在本申请的一些可选实施例中，DHCPv6客户端可以通过组播方式向 多个DHCPv6服务器发送第二报文比如solicit报文。
在本申请的一些可选实施例中，若DHCPv6客户端从多个DHCPv6服务器接收到第一报文，则DHCPv6客户端可以将多个DHCPv6服务器中的满足预设条件的服务器确定为目标DHCPv6服务器，并将该目标DHCPv6服务器发送的第一报文中的第一字段指示的Locator段确定为目标Locator段。
在本申请的一些可选实施例中，上述满足预设条件的服务器可以为多个DHCPv6服务器中优先级最高的服务器，也可以为多个DHCPv6服务器中的符合一定选取规则的一个服务器，对此不作限定。
在本申请的一些可选实施例中，在确定目标DHCPv6服务器之后，DHCPv6客户端可以分别向多个DHCPv6服务器发送第三报文；其中，该第三报文包括第三字段，第三字段用于指示目标DHCPv6服务器的标识ID，以便所有相关DHCPv6服务器获取DHCPv6客户端确定的目标服务器。
在本申请的一些可选实施例中，第三报文可选为请求(request)报文。
在本申请的一些实施例中，第三字段可选为选项(option)字段。比如，第三字段为request报文中的专用option字段，比如可以表示为option CC。
在本申请的一些实施例中，DHCPv6客户端可以通过组播方式向多个DHCPv6服务器发送第三报文比如request报文。
在本申请的一些可选实施例中，在分别向多个DHCPv6服务器发送第三报文之后，DHCPv6客户端可以从目标DHCPv6服务器接收第四报文；其中，该第四报文包括第四字段，第四字段用于确认将目标Locator段分配给DHCPv6客户端使用。
在本申请的一些可选实施例中，第四报文可选为回复(reply)报文。
在本申请的一些可选实施例中，第四字段可选为选项(option)字段。比如，第四字段为reply报文中的专用option字段，比如可以表示为option  DD。
在本申请的一些可选实施例中，上述的第四字段还可以确认相应Locator的其他需要的配置参数，比如Locator值/长度、Block长度、Node长度等。
需要说明的是，上述的第一字段、第二字段、第三字段和第四字段可以具有不同的长度，也可以具有相同的长度，基于实际需求而定，对此不作限定。
请参见图4，图4是本申请实施例提供的一种分配标识的方法的流程图，该方法应用于DHCPv6服务器。如图4所示，该方法包括如下步骤：
步骤41：向DHCPv6客户端发送第一报文。
本实施例中，第一报文可以包括第一字段，该第一字段用于指示为DHCPv6客户端分配的Locator段，该Locator段为SRv6协议体系中的网络节点标识段，主要用于组成SID，以实现相应路由转发。
在本申请的一些可选实施例中，第一报文可选为通告(advertise)报文。
在本申请的一些可选实施例中，第一字段可选为选项option字段。比如，第一字段为advertise报文中的专用option字段，比如可以表示为option BB。
在本申请的一些可选实施例中，上述的第一字段还可以指示相应Locator的其他需要的配置参数，比如Locator值/长度、Block长度、Node长度等。
本申请实施例的分配标识的方法，可以由DHCPv6服务器向DHCPv6客户端发送第一报文，该第一报文包括第一字段，该第一字段用于指示为DHCPv6客户端分配的Locator段。由此，可以扩展DHCPv6，由DHCPv6服务器向DHCPv6客户端配置Locator段，从而使得DHCPv6服务器和客户端之间可以正常收发SRv6报文，保证SRv6协议体系运行。
在本申请的一些可选实施例中，上述向DHCPv6客户端发送第一报文之前，DHCPv6服务器可以从DHCPv6客户端接收第二报文，该第二报文包括第二字段，第二字段用于请求DHCPv6服务器为DHCPv6客户端分配Locator段。
在本申请的一些实施例中，第二报文可选为寻求(solicit)报文。
在本申请的一些实施例中，第二字段可选为选项(option)字段。比如，第二字段为solicit报文中的专用option字段，比如可以表示为option AA。
在本申请的一些可选实施例中，在向DHCPv6客户端发送第一报文之后，DHCPv6服务器可以从DHCPv6客户端接收第三报文；其中，该第三报文包括第三字段，第三字段用于指示目标DHCPv6服务器的ID。目标DHCPv6服务器为DHCPv6客户端确定的向其发送第一报文的多个DHCPv6服务器中的优先级最高的一者。
在本申请的一些可选实施例中，第三报文可选为请求(request)报文。
在本申请的一些可选实施例中，第三字段可选为选项(option)字段。比如，第三字段为request报文中的专用option字段，比如可以表示为option CC。
在本申请的一些可选实施例中，DHCPv6客户端可以通过组播方式向多个DHCPv6服务器发送第三报文比如request报文。
在本申请的一些可选实施例中，在从DHCPv6客户端接收第三报文之后，DHCPv6服务器可以先根据第三报文中的第三字段指示的目标DHCPv6服务器的标识，判断自身是否是目标DHCPv6服务器；然后，若判断出自身是目标DHCPv6服务器，则向DHCPv6客户端发送第四报文；其中，该第四报文包括第四字段，第四字段用于确认将目标Locator段分配给DHCPv6客户端使用，该目标Locator段为目标DHCPv6服务器分配的Locator段。而若判断出自身不是目标DHCPv6服务器，则无需向DHCPv6 客户端返回报文。
在本申请的一些可选实施例中，第四报文可选为回复(reply)报文。
在本申请的一些实施例中，第四字段可选为选项(option)字段。比如，第四字段为reply报文中的专用option字段，比如可以表示为option DD。
在本申请的一些可选实施例中，上述的第四字段还可以确认相应Locator的其他需要的配置参数，比如Locator值/长度、Block长度、Node长度等。
下面，结合图5对本申请实施例中的Locator分配过程进行说明。
如图5所示，具体的Locator分配过程可以包括：
步骤51：DHCPv6客户端通过组播方式向多个DHCPv6服务器发送寻求(solicit)报文，其中携带第二字段比如option AA，用于请求DHCPv6服务器为其分配Locator段。
步骤52：DHCPv6服务器向DHCPv6客户端回复通告(advertise)报文，其中携带第一字段比如option BB，用于指示为DHCPv6客户端分配的Locator段以及其他需要的配置参数，比如Locator值/长度、Block长度、Node长度等。
步骤53：DHCPv6客户端选择优先级最高的一台服务器作为目标DHCPv6服务器，并通过组播方式向所有相关DHCPv6服务器发送请求(request)报文，其中携带第三字段比如option CC，用于指示目标DHCPv6服务器的ID。
步骤54：目标DHCPv6服务器向DHCPv6客户端发送回复(reply)报文，其中携带第四字段比如option DD，用于确定将目标Locator段和其他需要的网络配置参数分配给DHCPv6客户端使用。
这样，借助上述的DHCPv6协议交互流程，可以实现SRv6的Locator的请求和分配。
