在这种组网模式下, 在网关上形成了两个逻辑子网 NetA、 NetB, NetA的用户由网关 负责分配地址, 并通过网络地址转换 NAT来实现 Internet接入, 位于 NetB的 STB其地址一 般采用 PPPoE从上行的网络设备来获得。在这种组网方式下, 位于 NetA的用户难以通过网 关来管理、 配置位于 NetB的桥接设备 STB, 原因在于:
在 NetB网络中网关充当网桥作用只能学习到桥接设备的 MAC地址,无法知道下行桥接 设备的 IP地址, 同时作为网桥在 NetB中也没有地址。 不知道桥接设备的 IP地址, 网关就 无法同桥接设备建立起基本的 IP通信,同时由于实际组网 NetB可能就是一个封闭的网络, 知道桥接设备在 NetB中的地址, 位于 NetA的用户也无法对其进行管理。
因此, 现有技术存在缺陷, 而有待于改进和发展。

图 1是现有技术和本发明的家庭网关的一种典型应用的组网图;
图 2是本发明方法的实现流程图。 具体实施方式
以下结合附图, 将对本发明的各较佳实施例进行较为详细的说明。
本发明所述桥接设备的管理方法, 其包括必要步骤为- 步骤一: 进行地址配置: 网关和终端通过自动 IP技术产生用于链路本地通信的地址。 步骤二: 进行信息釆集: 网关通过 UPnP与终端通信, 获取桥接设备的信息。
步骤三: 建立规则: 网关根据桥接设备的信息建立基于端口的静态 NAT规则。
步骤四: 访问处理: 网关通过 NAT来提供用户对终端的配置管理。
步骤五: 状态检测: 网关检测桥接设备的状态。
本发明方法需要在网关和桥接的终端设备同时实施, 本发明方案的实施是通过对目
前现有技术进行扩展来完成, 主要涉及到三个技术: Auto- IP、 通用即插即用 UPnP、 网络 地址转换 NAT, 其中 Auto-IP (RFC3927)是 IETF定义的一种 IP地址自动配置技术, 用于在 接口上自动生成用于链路之内通信的 IPv4地址, UPnP是一种广泛用于家庭网络设备互联 的协议规范, NAT用于网络接入设备, 实现地址转换。
采用本方案的组网结构可见图 1所示, 详细的流程见图 2所示, 具体的实施步骤包括: 第一步, 网关的桥接端口 (Lan Port 2)和终端以太口上利用自动 IP地址配置技术 来产生一个用于链路本地通信的接口地址, 如 169. 254. x. x/16, 由于终端采用桥接方式, 其全局使用的 IP地址不由网关分配, 通过使用链路本地 IP地址可以在网关的桥接端口和 终端设备之间建立基本的 IP通信,通过使用 RFC3927规定的流程可以确保在同一条链路上 产生的链路地址不会重复。
第二步, 终端和网关均启用 UPnP, 终端实现设备 (Device) 功能, 网关充当控制点
(Control Point)功能, 网关使用链路本地地址作为源地址在桥接口上向终端发送组播 如 239.. 255. 255. 250: 1900查询消息, 终端使用链路本地地址单播响应, 将终端的基本信 息包括设备标识、 版本、 管理接口地址等传回。 网关收到响应后在网关上建立桥接设备 数据库, 数据库以网关的接口为索引来记录各个接口下的桥接终端的设备信息。
第三步, 网关根据桥接设备数据库中信息,包括接口索引、桥接设备管理接口地址, 来产生网关的静态 NAT规则:
在 WAN侧接口上选取一个空闲的 TCP端口, 建立从 MN侧一个端口到桥接设备的 NAT转 换规则, 用于实现家庭网关中的虚拟服务器功能。
在 LAN侧非桥接的各个端口也完成如上所述的 NAT转换规则建立。
在桥接设备的数据库中记录与本终端相关的转换条目。
对图 1的组网来说是在 Portl和 PVC1上建立到 STB之间建立 NAT转换规则。
第四步, 位于 Portl的本地用户或从 WAN通过 PVC1的远端用户访问网关信息时可以观 察到其下桥接设备的基本信息, 当用户请求访问终端时, 如点击桥接设备的链接时, 网 关从数据库中获取该桥接终端相关的 NAT条目, 选取与用户的入接口 PVC1或者 Portl相同 的 NAT条目, 并将对桥接设备的访问重定向为对 NAT条目的外侧端口的访问, 然后网关通 过 NAT将用户的 http访问转换后转发到桥接设备的管理接口, 从而实现对桥接设备的管 理。
第五步, 网关对桥接数据库中的各个桥接设备需要进行定期的査询, 以检查桥接设 备的信息包括设备标识、 版本、 管理接口地址是否有变化。 查询使用 UPnP的请求消息来
进行: 在各个桥接口上以接口的链路本地地址作为源地址, 桥接设备的链路地址作为目 的地址发送单播的 UPnP査询消息, 设备使用链路地址进行单播回应。 收到的设备信息如 果有变化需要进行相应的处理: 如果管理接口地址有变化, 网关需要更新以前建立的 NAT 规则, 设备标识、 版本信息变化则简单更新数据库中内容; 如果查询无响应则删除数据 库中的对应条目, 并清除与该桥接设备相关的 NAT条目。
本发明的一种桥接设备的管理方法, 和现有技术相比, 釆用本发明方法实现了网关 对桥接设备的管理, 有利于实现家庭网络的统一管理; 并且该发明中实现的网关与桥接 设备通信机制可以扩展实现两者之间复杂的信令交互。 但实施本发明方案的还需注意: 釆用自动 IP地址配置技术时,对采用 PPPoE方式的终端应该在其以太接口上进行,不 能在 ppp接口上进行;对采用 DHCP方式的终端需要严格限制自动配置产生的链路本地地址 的使用, 只能与同链路的端点通信时使用此地址。
为防止广播流量对上端的 DSLAM、 BNAS的影响,桥接终端启用 UPnP时应该抑制组播的 发出, 网关发出的组播査询报文应将 TTL设置为 1。
从安全考虑在桥接终端上启用的 UPnP应该只使用链路本地地址进行通信。
应当理解的是, 本发明上述针对具体实施例的描述较为具体, 并不能因此而理解为 对本发明专利保护范围的限制, 本发明的专利保护范围应以所附权利要求为准。
