Description

一种提供 IPv6服务的系统和方法
技术领域
本发明涉及互联网协议 ( Internet Protocol, IP )技术， 特别是一种提 供互联网协议版本 6 ( Internet Protocol version 6, IPv6 )服务的系统和方 法。 发明背景
现有的互联网协议版本 4 ( Internet Protocol version 4 , IPv4 )在地址 空间、 端到端的 IP连接、服务质量、 网络安全和移动性等方面都暴露出 不足。 IPv6所能提供的巨大的地址空间以及所具有的诸多潜在优势和功 能， 使其成为构筑下一代网络的重要基础。 与 IPv4相比， IPv6优势的 一个重要表现就是实现了切实的移动性。移动互联网协议版本 6 ( Mobile Internet Protocol version 6, Mobile IPv6 )在新功能和新月良务方面可以提 供更大的灵活性。移动 IPv6能够通过筒单的扩展， 满足大规模移动用户 的需求， 能够为在互联网上运行的每个移动终端提供一个全球唯一的 IP 地址。 这样， 它就能在全球范围内解决有关网络和访问技术之间的移动 性问题。
虽然同 IPv4网络相比， IPv6网络拥有更多的优点，但是在相当长的 时间内， IPv4网络和 IPv6 网络将会共同存在。 目前几乎每个现有的网 络及其连接设备都支持 IPv4, 因此要想很快就完成从 IPv4网络到 IPv6 网络的转换是不切实际的。 当 IPv4网络和 IPv6网络共存的时候， 很多 情况下， 在 IPv4网络中的用户会有接收 IPv6服务的需求， 并且与通信 伙伴不在同一 IPv6网络的用户也会有接收 IPv6服务的需求， 因此必须 考虑如何给这些用户提供 IPv6服务。 为了在 IPv4网络和 IPv6网络共存时向用户提供 IPv6服务， 目前的 一个解决方法是将现有网络升级为支持 IPv4和 IPv6双协议栈的网络。 该方法是将网络中的所有路由器、 交换机等三层网络设备和用户终端设 备都升级支持 IPv6和 IPv4欢协议栈，其中每个用户都有 IPv4地址和 IPv6 地址。 这样当用户间可以进行 IPv4互通时使用 IPv4协议栈进行通信； 当网络中有 NAT等设备时， 由于使用私有地址的问题， 用户使用 IPv4 协议栈将不能进行正常的通信， 这时用户可以使用 IPv6协议栈进行通 信。 这种将现有网络升级为支持 IPv4和 IPv6欢协议栈的方法要求将网 络中所有路由器、 三层交换机等三层网络设备全面升级， 因此需要用户 重新对网络设备进行投资， 进而造成成本过高， 不利于本方法的推广使 用。 同时， 当用户漫游到其它网络时， 尤其是只支持 IPv4网络时， 应用 这种方法的用户的 IP地址也将变化， 不能用来作为标识用户的唯一标 士 在现有技术中，用户还可以通过标准的隧道方式接入到 IPv6网络以 接收某些 IPv6服务，其中这些隧道可以包括站内自动隧道寻址协议（the Intra-site Automatic Tunnel Addressing Protocol, ISATAP ) l¾道、 6to4 1¾ 道、配置隧道、穿过 NAT的基于 UDP的 IPv6隧道技术 ( Tunneling IPv6 over UDP through NATs, TEREDO ) 隧道。 当用户使用标准隧道方式接 入 IPv6网路时，用户可从隧道网关上得到一个与隧道相关的 IPv6地址， 此时用户可以通过这一地址进行通信以接收 IPv6服务。这种通过标准隧 道机制而提供的 IPv6服务和网絡配置有关，服务并不全面。例如不支持 从 IPv6网络到 IPv4网络的漫游服务。而且，通过标准隧道机制接入 IPv6 网络产生的 IPv6地址通常与用户的 IPv4地址相关， 而 IPv4地址通常使 用动态地址， 所以当用户的 IPv4地址变化时， IPv6地址也会有相应的 变化， 因此造成不能用 IP地址标识一个用户，从而限制了用户端到端通 信的有效性。 并且由于用户得到的 IPv6地址和 IPv4地址相关， 所以这 些 IPv6地址在互联网中的可路由能力不强， 比如 6to4地址就通常只能 作为局部通信使用， 因此也限制了用户的正常通信服务。 发明内容
本发明的主要目的在于提出一种提供 IPv6服务的系统，以降低投资 成本。

C、 用户的通信伙伴以所述的家乡地址为目的地地址发送报文；
D、 家乡代理收到报文后， 转发该报文到用户的转交地址；
E、 向用户提供 IPv6服务。
步骤 A所述用户接入 IPv6网络为用户通过隧道网关从 IPv4网络接 入 IPv6网络；
步骤 A和步骤 B之间进一步包括： 注册用户到隧道网关， 由隧道网 关代替用户申请可路由的 IPv6地址，并建立所述转交地址到该可路由的 IPv6地址的映射关系；
所述注册用户到节点注册代理为： 隧道网关注册用户到节点注册代 理； 所述节点注册代理向用户通知家乡地址为： 节点注册代理将所申请 的家乡地址通知隧道网关， 隧道网关向用户通知该家乡地址；

一种提供 IPv6服务的系统， 包括 IPv6网絡和 IPv6网络中的家乡代 理，该系统进一步包括节点注册代理，所述节点注册代理在该 IPv6网络 中，用于代替用户向家乡代理申请家乡地址，代替用户注册到家乡代理， 并将所申请的家乡地址通知用户。
该系统进一步包括 IPv4 网络和隧道网关， 所述隧道网关位于所述 IPv4网络和 IPv6 网絡之间， 支持从隧道网关到节点注册代理的远程注 册， 并支持用户的报文转发。
所述节点注册代理集成在家乡代理上、 或是单独的设备。
所述隧道网关是单独的设备、 或隧道接入设备所在子网的设备。 从以上技术方案可以看出， 本发明提出了一种提供 IPv6服务的系 统， 该系统包括 IPv6网络和 IPv6网络中代替用户申请家乡地址、 并代 替用户注册家乡地址到家乡代理和将所申请的家乡地址通知用户的节 点注册代理。 通过在 IPv6 网络中加入该节点注册代理， 当用户由其它 IPv6网络接入到本 IPv6网络时， 节点注册代理为该用户远程注册获得 家乡地址， 然后用户将家乡地址和接入 IPv6 网络时获得的转交地址捆 绑， 用户的通信伙伴以用户的家乡地址为目的地地址发送报文， 家乡代 理收到报文后，转发报文到用户接入 IPv6网絡时获得的转交地址， 最后 实现接收 IPv6服务。所以应用本发明不需要对路由器等三层网络设备进 行全面升级而实现了向从其它 IPv6网 矣入到本 IPv6网络的用户提供 IPv6服务， 从而极大地降低了投资成本。
同时， 当用户通过隧道由 IPv4网络接入到 IPv6网络时， 在该系统 的隧道网关中增加既支持从隧道网关到节点注册代理的远程注册， 又支 持用户报文转发的功能。 通过从隧道网关到节点注册代理的远程注册用 户可获得家乡地址，通过隧道网关的报文转发用户可接受 IPv6服务， 所 以此时便实现了当用户通过隧道接入 IPv6网络时， 向该用户提供 IPv6 服务。
本发明还提出了一种提供 IPv6服务的方法， 当移动节点接入 IPv6 网络时， 通过远程注册机制注册到家乡代理， 并将在远程注册过程中获 得的 IPv6地址作为自己的家乡地址， 而将该移动节点在接入 IPv6网络 时获得的 IPv6地址作为转交地址，通过这种远程注册机制，该移动节点 就成为注册在家乡代理上的一个移动节点， 从而使得移动节点获得固定 的全球 IPv6地址， 便于 IPv6用户之间的互通， 解决了以隧道方式接入
IPv6网络时对端到端通信有效性的限制问题。 同时， 应用本方法后， 移 动用户可在家乡代理的支持下进行 IPv4和 IPv6网络之间的漫游， 所以 应用本方法在不增加投资成本的情况下还可提供更多的 IPv6服务。
同时， 由于应用本发明后， 移动节点已经注册在家乡代理上， 所以 用户获得了固定的全球 IPv6地址， 而该 IPv6地址不会随着移动节点漫 游到其它网络而变化，所以真正实现了将 IP地址用来作为标识用户的标 士 附图简要说明

为使本发明的目的、 技术方案和优点表达得更加清楚明白， 下面结 合附图及具体实施例对本发明再作进一步详细的说明。
本发明的主要思想是在 IPv6网络中增加代替用户申请家乡地址、并 代替用户注册家乡地址到家乡代理和将所申请的家乡地址通知用户的 节点注册代理。 当用户由其它 IPv6网络接入到本 IPv6网络时， 通过节 点注册代理为该用户通过远程注册获得家乡地址， 然后用户将家乡地址 和接入 IPv6网络时获得的转交地址捆绑， 通过移动 IPv6转发机制实现 通信， 以实现向用户提供 IPv6服务。 当用户通过隧道方式由 IPv4网络 接入到 IPv6网絡时，在该系统中再增加既支持从隧道网关到节点注册代 理的远程注册、 又支持用户报文转发的隧道网关， 通过远程注册用户可 获得家乡地址， 通过隧道网关的报文转发用户可接受 IPv6服务。
图 1为本发明一实施例提供 IPv6服务的系统示意图。 如图 1所示， 该系统包括 IPv6子网 A、 IPv6子网 B和 IPv6子网 A中的节点注册代理。 该节点注册代理用于代替用户申请家乡地址， 并代替用户注册家乡地址 到家乡代理和将所申请的家乡地址通知用户。 当用户由 IPv6子网 B接 入 IPv6子网 A时， 首先用户获得转交地址， 然后用户远程注册到节点 注册代理， 节点注册代理代替用户申请家乡地址， 并代替用户注册家乡 地址到家乡代理和向用户通知家乡地址， 接着用户从节点注册代理获得 家乡地址，并且将家乡地址和转交地址捆绑，最后可利用移动 IPv6转发 机制和用户通信， 以向用户提供 IPv6服务。
基于图 1所示的示意图， 图 2为本发明一实施例向通过隧道接入的 用户提供 IPv6服务的系统示意图。 如图 2所示， 该系统包括 IPv6子网、 IPv6子网中的节点注册代理、 IPv4网络以及 IPv4网络与 IPv6网络之间 的隧道网关。 节点注册代理用于代替用户申请家乡地址， 并代替用户注 册家乡地址到家乡代理和将所申请的家乡地址通知用户。 隧道网关既支 持从隧道网关到节点注册代理的远程注册， 又支持用户的报文转发。 当 用户通过隧道方式接入 IPv6网络时， 获得 IPv6地址， 可假设该 IPv6地 址为 IPv6地址 A; 用户注册到隧道网关， 隧道网关代替用户申请在用户 接入的该 IPv6网络中和该用户的通信伙伴的 IPv6网絡中可路由的 IPv6 地址 B, 隧道网关建立 IPv6地址 A到该可路由的 IPv6地址 B的映射关 系； 隧道网关注册用户到家乡代理， 并从节点注册代理获得用户的家乡 地址； 用户获得家乡地址后， 用户的家乡地址就已经确定， 并且 IPv6 地址 A作为用户的转交地址 1 , IPv6地址 B作为用户的转交地址 2, 通 过这些地址发送给用户的报文，都可以在移动 IPv6的终端中的一个会话 中使用， 从而实现向用户提供 IPv6服务。
图 1和图 2所示的节点注册代理在具体实现上既可以是家乡代理设 备上的一个附属功能， 也可以集成在其它网络上， 还可以是一个单独的 网络设备。 图 2所示的隧道网关实现上既可以是一个单独的设备， 也可 以是隧道接入设备所在子网内的一个其它设备。
图 3为本发明提供 IPv6服务的流程图。如图 3所示，包括以下步驟： 步骤 301： 用户接入 IPv6网络， 获得转交地址；
步骤 302: 注册用户到节点注册代理， 由节点注册代理代替用户申 请家乡地址和注册该家乡地址到家乡代理， 并向用户通知该家乡地址； 步骤 303: 用户的通信伙伴以该用户的家乡地址为目的地地址发送 报文；
步骤 304: 家乡代理收到报文后， 转发该报文到用户的转交地址； 步骤 305: 用户收到报文后， 便建立了通信连接， 从而可以向用户 提供 IPv6服务。
以上过程中， 在步骤 301 , 用户接入 IPv6网络的接入方式既可以是 从一个 IPv4的网络中以隧道的方式接入到 IPv6网络中， 也可以是从其 它 IPv6网络中直接接入到 IPv6网络。如果用户是通过隧道方式接入 IPv6 网络，则在步骤 305利 ji)隧道网关和移动 IPv6转发机制实现向用户提供 IPv6服务， 如果用户是从其它 IPv6网络中直接接入 IPv6网络， 那么在 步驟 305利用移动 IPv6的转发机制实现向用户提供 IPv6服务。
基于图 3所示的提供 IPv6服务的总体流程图，图 4为本发明一实施 例的提供 IPv6服务的流程图。 如图 4所示， 包括以下步驟：
步骤 401: 用户接入 IPv6网络， 获得 IPv6地址 A。
用户在接入 IPv6网络时将获得一个 IPv6地址， 可假设该 IPv6地址 为 IPv6地址 A。
步驟 402: 判断用户是否为通过隧道方式接入 IPv6网络， 如果是执 行步骤 409及其后续步骤， 否则执行步骤 403及其后续步驟。
步骤 403: 判断用户与家乡代理是否在同一子网中， 如果是则执行 步骤 404并结束， 否则执行步骤 405及其后续步骤。
步骤 404: 通过移动 IPv6注册和转发机制实现通信， 实现向用户提 供 IPv6服务， 并结束。
在这里， 当用户是从其它 IPv6子网中直接接入到 IPv6子网时， 如 果用户和家乡代理在同一个 IPv6子网，那么用户不需要使用远程注册机 制， 可以通过移动 IPv6注册和转发机制进行通信， 以向用户提供 IPv6 服务。
步骤 405： 通过节点注册代理远程注册用户到家乡代理。
步骤 406: 用户从节点注册代理获得 IPv6家乡地址。
步骤 407: 用户将家乡地址和转交地址捆绑， 用于报文的收发。 步骤 408: 利用移动 IPv6的转发机制通信， 向用户提供 IPv6服务。 从步骤 405到步骤 408完成了对从其它 IPv6子网接入本 IPv6子网， 但和家乡代理不在同一子网的用户的注册过程 , 此时在步骤 408用户可 以利用移动 IPv6的转发机制通信， 以接收 IPv6服务。
步驟 409: 用户注册到隧道网关。
步骤 410: 隧道网关代替用户申请可路由的 IPv6地址 B, 隧道网关 建立 IPv6地址 A到 IPv6地址 B的映射关系。
因为 IPv6地址 A可能不是一个在互联网上可路由的 IPv6地址， 所 以此时用户不能直接启动远程注册机制，但是因为用户接入 IPv6网络时 的隧道网关能够路由 IPv6地址的报文，所以此时隧道网关可以代替用户 申请一个在用户接入的 IPv6网络和该用户的通信伙伴所在的 IPv6网絡 中都可路由的 IPv6地址， 艮设隧道网关申请的该可路由的 IPv6地址为 IPv6地址 B。 在隧道网关上将转发艮文源、 目的地址中的 IPv6地址 B 映射为 IPv6地址 A。 此时， 用户将获得两个 IPv6地址， 分别为 IPv6地 址 A和 IPv6地址 B,其中 IPv6地址 A用于隧道网关和用户之间的 4艮文 转发， 而 IPv6地址 B用于隧道网关到 IPv6网络的报文转发。
步骤 411: 隧道网关代替用户通过远程注册机制注册到家乡代理， 隧道网关从节点注册代理获得家乡地址。
用户获得 IPv6地址 B后， 道网关启动远程注册机制，将用户注册 到家乡代理上， 并将用户的 IPv6地址 Β通知给家乡代理而作为用户的 转交地址。 在此过程中， 隧道网关也将获得用户的家乡地址， 并将该家 乡地址通知给用户。
步骤 412: 用户从隧道网关得到 IPv6地址 Β, 用户将 IPv6地址 A 作为自己的转交地址 1 , 将 IPv6地址 B作为自己的转交地址 2。
用户获得家乡地址后， 用户的家乡地址就已经确定， 并且 IPv6地址 A作为用户的转交地址 1 , IPv6地址 B作为用户的转交地址 2。 用户将 IPv6地址 A、 IPv6地址 B和家乡地址捆绑，通过这些地址发送给用户的 报文， 都可以在移动 IPv6的终端中的一个^^舌中使用。
从步驟 409到步骤 412完成了当用户通过隧道方式接入 IPv6网络时 在隧道网关和家乡代理的注册。 当用户通过隧道方式接入 IPv6网络， 并 完成在隧道网关的注册和家乡代理的注册后， 便可建立用户和通信伙伴 的通信， 以接收 IPv6服务。
步骤 413: 通信伙伴通过用户的家乡地址发送艮文给用户。
当用户通过隧道方式接入 IPv6网络，并完成在隧道网关的注册和家 乡代理的注册后， 通信伙伴发给用户的报文， 将首先发送到用户的家乡 地址。
步驟 414: 家乡代理首先收到报文， 并转发报文 IPv6地址 B。
家乡代理收到通信伙伴发过来的报文后，转发报文到用户的 IPv6地 址 B, 隧道网关便会收到该报文。
步骤 415: 隧道网关收到报文， 并转发报文 IPv6地址 A。
隧道网关将报文转发到用户的 IPv6地址 A,用户通过隧道就会接收 到通信伙伴发出的报文。
步驟 416: 用户收到报文， 发起绑定更新过程。
用户收到报文后， 启动正常的绑定更新过程， 向通信伙伴通知 IPv6 地址 B, 使得通信伙伴发送随后的报文时将采用用户的 IPv6地址 B作 为目的地地址。
步驟 417: 通信伙伴通过用户的 IPv6地址 B与用户通信， 向用户提 供 IPv6服务。
当用户通过绑定更新过程通知通信伙伴用 IPv6地址 B与用户通信 后， 通信伙伴随后发送的艮文将采用用户的 IPv6地址 B作为目的地地 址。 隧道网关从通信伙伴接收 IPv6地址 B的报文， 并转发报文到 ΙΡνό 地址 Α, 最后由用户接收。 从步骤 413 到步骤 417 完成了建立用户和通信伙伴的通信以接收 IPv6服务的过程。 图 5为本发明一实施例的向通过隧道接入 IPv6网络 的用户提供 IPv6服务示意图。
当用户接入 IPv6网絡，并完成注册以后，如果用户漫游到一个 IPv4 网络，此时用户需要采用隧道方式接入 IPv6网络。假设此时用户通过隧 道方式接入到 IPv6网络得到的 IPv6地址为 IPv6地址 C, 因为 IPv6地 址 C可能不是可路由的 IPv6地址， 所以用户不能按照正常的移动 IPv6 转发机制与通信伙伴通信。 此时用户需要在隧道网关注册， 并由隧道网 关为用户分配一个新 IPv6地址，该 IPv6地址在用户接入的 IPv6网络中 和该用户的通信伙伴的 IPv6网络中是可路由，设该 IPv6地址为 IPv6地 址0。 隧道网关还需要代替用户向家乡代理进行注册， 以告诉家乡代理 用户的转交地址是 IPv6地址 D,然后隧道网关还建立 IPv6地址 C到 IPv6 地址 D的映射关系。
当用户接入到 IPv6 网络， 并注册到家乡代理后还可以漫游到 IPv4 网络接收 IPv6的服务。 图 6为本发明一实施例的向已经漫游到 IPv4网 絡后的用户提供 IPv6服务流程示意图。 如图 6所示， 包括以下步骤： 步骤 601： 用户漫游到 IPv4网络中；
步骤 602: 用户通过隧道方式接入 IPv6网络， 并得到 IPv6地址 C; 步骤 603: 用户注册到隧道网关；
步骤 604: 隧道网关代替用户申请在用户接入的该 IPv6网络中和该 用户的通信伙伴的 IPv6网络中都可路由的 IPv6地址 D, 隧道网关建立 IPv6地址 C到 IPv6地址 D的映射关系；
步骤 605: 随道网关代替用户注册到家乡代理， 并将用户的 IPv6地 址 D作为用户的转交地址通知家乡代理；
步骤 606: 用户从隧道网关得到 IPv6地址 D, 并将 IPv6地址 C作 为转交地址 1 , IPv6地址 D作为转交地址 2;
步骤 607: 通信伙伴以用户的家乡地址为目的地地址发送报文； 步骤 608: 家乡代理首先收到报文， 转发^ =艮文到 IPv6地址 D;
步骤 609: 隧道网关收到 4艮文， 转发 ^艮文到 IPv6地址 C;
步骤 610: 用户收到报文， 并发起绑定更新过程；
步骤 611:通信伙伴通过用户的 IPv6地址 D与用户通信，以接收 IPv6 服务。
以上所述， 仅为本发明的较佳实施例而已， 并非用于限定本发明的 保护范围。凡在本发明的精神和原则之内， 所作的任何修改、等同替换、 改进等， 均应包含在本发明的保护范围之内。
