Description

新网与互联网互通的实现方法、 ***及通信端 技术领域
本发明涉及通信领域, 尤其是一种新网与互联网互通的实现方法、 *** 及通信端。
背景技术
随着信息技术的发展, 以互联网为代表的信息网络在经济和社会发展中 起到了越来越重要的作用。但互联网也在使用过程中暴露了越来越多的问题。 互联网设计之初, 只考虑了固定的可信任的终端, 不支持终端移动性, 也没 有内在的安全保障机制。 随着 3G、 后 3G、 4G等无线技术的发展, 互联网对 移动终端的支持成为越来越紧迫的课题。 同时, 随着互联网应用范围的扩大, 安全问题也更加突出, 这些问题在现有的互联网技术框架下已经很难解决。
TCP/IP协议是互联网的基础。 IP地址具有身份、 位置的双重属性, 是互 联网无法支持移动性的根源。 作为终端的身份属性, IP地址在终端移动过程 中不能改变, 否则 TCP、 UDP等上层业务连接会随着地址的改变而中断; 作 为终端的位置属性, IP地址在终端移动过程中必须改变 (地址必须具有当前 所在的子网前缀) , 否则路由器无法把数据包正确地转发到终端。 同时, IP 地址的双重属性也是互联网的安全性得不到根本解决的原因所在。 由于 IP地 址必须包含终端的位置属性, 所以移动终端无法分配到固定的 IP地址, 因此 在互联网上无法根据 IP地址确定黑客等攻击者的身份。 这是当前互联网上攻 击、 诈骗、 滥用等安全问题得不到解决的根本原因。
针对 IP协议具有双重属性的缺陷, 业界在研究多种基于身份、 位置分离 的下一代网络技术, 一般分为基于网络和主机的两类解决方案。 新网是一种 基于网络的解决方案, 可以减少互联网路由表规模, 间接可以解决主机的移 动性。 在新网的解决方案中, 将边界路由设备的位置 IP和设置为标识主机的 IP地址分离在两个不同的空间之中, 一个边界路由设备可以接入任意的主机 IP地址, 这些主机 IP地址段并不暴露在新网骨干网之中, 骨干网络路由表只 存储接入业务路由器的公共 IP地址, 也就是说对于骨干网而言, 接入业务路 由器相当于网络的主机。
新网的架构图如图 1所示。 图中接入业务路由器称为 ASR。 ASR路由器 边界内的主机发起通信时源、 目标地址均是终端主机的识别符 (AID), ASR收 到消息时查询得到目标 AID所对应的路由交换标识 RID, 并将原始报文进行 转换, 形成报文头部的源、 目标地址分别为 RID的数据包。 当数据报文到达 目标 ASR, 经过解析映射, 形成源、 目的地址均为 AID的数据报文, 转发到 目的终端。
基于新网的建设、 推广、 普及需要一段较长的时间, 新网与传统互联网 在较长的时期内将同时存在。 所以两个网络需要进行互通。
新网与传统互联网的互通, 意指新网终端与传统互联网的终端可以相互 通信。 新网终端可以访问传统互联网提供的月良务, 传统互联网的终端也可以 访问新网的服务。 但目前还没有完善的互通方案来解决这一问题。

Legacy网络业务服务器或终端的身份标识(简称 AID ) 的编码由新网根 据对终端兼容性要求、 新网发展阶段而定, 可以是 Legacy网络中业务服务器 或终端公网 IPv4地址, 可以是 Legacy网络中业务服务器或终端公网 IPv6地 址,也可以是含有 Legacy网络中业务服务器或终端公网 IPv4地址的长位(超 过 32位)编号。
Legacy网络业务服务器或终端的路由标识(简称 RID ) 的编码由新网根 据对终端兼容性要求、 新网发展阶段而定, 可以是 Legacy网络中业务服务器 或终端公网 IPv4地址, 可以是 Legacy网络中业务服务器或终端公网 IPv6地 址, 也可以是含有 Legacy网络中业务服务器或终端公网 IP地址的长位(超 过 32位)编号, 还可以是 ISN的位置标识。 比较简单的做法是, Legacy网 络业务服务器或终端的 AID、 RID及 IP地址是相同的, 釆用该标识规则, 即 不需要另外分配, 也无需保存该映射关系。
新网业务服务器或终端和 Legacy互通的 IP地址可以是新网业务服务器 的身份标识 AID , 可以是独享的固定的公网 IP地址, 也可以是 Legacy网和 新网共享的专设置为互通的公网 IP地址。 为了实现以上互通数据包的转换, ISN需要查询本地或映射服务器中保 存的 RID和 IP地址的映射关系或在, 以进行数据包转换时的地址转换处理, 还需要将转换后的数据包进行转发, 为了减轻 ISN的负担, 具体实现时, 可 以在新网网和 Legacy网络的边界增设与 ISN连接的边界网关 (简称 BG ) , 由 BG来实现 IP数据包的路由和转发, ISN的数量和位置根据互通的流量和 分布所需要的负荷分担进行配置。 如图 3所示。
以下以图 3所示的网络架构为例, 对本发明互通方法进行详细说明:
新网中每个终端用户都有一个身份标识, 简称为 AID, 身份标识 AID在 新网中是不能路由的,在 Legacy网中通过特定的路由设计和扩散是可以路由; 每个终端用户也都会动态分配一个路由标识简称为 RID。
应用实例一
如图 4所示, 新网终端访问 Legacy网络中业务服务器数据流上行(从新 网流向 Legacy网络) 时的数据包处理过程包括以下步骤:

步骤 A2: ASR查询 AID和 RID的映射关系后进行数据包转换, 转换后 的数据包的源地址为新网终端的 RID, 目的地址为 Legacy 网络业务服务器 RID;

步骤 B5: 步骤 B 4中重组的数据包经路由转发到 ASR;
步骤 B6: ASR解析新网终端 RID, 查询映射关系, 形成目的地址为终端 AID,源地址为 Legacy网络业务服务器 AID的数据包,查找数据包的出接口; 步骤 B7: 根据出接口, 将数据包发向相应的新网访问终端。
C )当 Legacy网络访问新网中业务服务器数据流下行(从 Legacy网络流 向新网 ) 时的数据流处理;
步骤 CI ~ C2: Legacy网络访问新网业务服务器的下行数据包经过 Legacy 网络、 BG到达 ISN; 其源地址为 Legacy网络的访问终端的 IP地址, 目的地 址为新网中业务月良务器和 Legace网络互通的 IP地址;
步骤 C3: ISN查询 IP地址和 RID的映射关系, 得到 Legacy网络的访问 终端和新网业务服务器对应的 RID;
步骤 C4: ISN根据映射关系将数据包转换成为新网中的数据包, 其源地 址为 Legacy网络访问终端 RID , 目的地址为新网业务服务器的 RID;
步骤 C5: 为步骤 C6中的数据包经路由转发到 ASR, ASR解析接入终端 的 AID , 查询映射关系, 重组形成目的地址为新网业务月良务器 AID , 源地址 为 Legacy网络访问终端 AID的数据包, 根据新网业务服务器 AID查询通往 新网业务服务器出接口;
步骤 C6: 根据出接口, ASR将数据包转发到相应的新网业务服务器。 D) 当 Legacy网络访问新网中业务服务器数据流上行(从新网终端流向 Legacy网络) 时的数据流处理;
步骤 Dl : Legacy 网终端访问新网业务服务器回复的上行数据包发向 ASR , 目的地址为 Legacy网络访问终端的 AID , 源地址为新网业务服务器的 AID;
步骤 D2 ~ D3: ASR根据 AID和 RID的映射关系将上行数据包转换成 为新网的数据包, 发向 ISN; 其源地址为新网业务服务器的 RID, 目的地址 为 Legacy网络终端 RID;
步骤 D4: 为步骤 D2中的数据包经过路由转发到 ISN时, ISN解析 RID, 根据映射获得 Legacy网络终端的 IP地址以及新网业务服务器和 Legacy网络 互通的 IP地址, ISN把数据包转换成为目的地址为 Legacy网络访问终端 IP 地址, 源地址为新网业务服务器设置为互通的 IP地址的数据包;
步骤 D5 ~ D7: ISN、 BG、 Legacy网络中根据路由转发 D3中重组后的上 行数据包到相应的 Legacy网络中的访问终端。
