    • The invention relates to a method for transparently exchanging data packets with a packet-oriented network, via which a number of network elements and a network node device are connected based on a common access method. The network elements are allocated unique local addresses only within the network. The network node device connects the packet-oriented network to an external device based on a point-to-point protocol and performs an address conversion of the address of a network element, said address being allocated within the packet-oriented network, into an address valid for the external device. A verification of message header entries of the data packets exchanged between the external device and the network element permits the establishment of a temporary transparent connection of the network element to the external device in the event an entry is detected the characterizes an expanded point-to-point protocol, e.g. PPPoE, whereby the address newly allocated by the external device is transmitted to the external device without address conversion.
    • 本发明涉及一种基于共享访问方法的数据分组与面向分组的网络进行透明交换的方法,多个网元和网络节点设备经由该数据包进行连接。 网络元素仅在网络内分配唯一的本地地址。 网络节点设备基于点对点协议将面向分组的网络连接到外部设备,并且将所述地址分配在面向分组的网络内的网元的地址的地址转换为地址转换为地址 对外部设备有效。 在外部设备和网络单元之间交换的数据分组的消息报头条目的验证允许在检测到条目的情况下建立网元的临时透明连接到外部设备, 点协议,例如 PPPoE,由此将由外部设备新分配的地址传送到外部设备而不进行地址转换。

    • The aim of the invention is to exchange data between an external device and applications installed on network elements of a packet-switching network by means of at least one tunnel connection. Said aim is achieved by connecting each network element to a network node device that is part of the tunnel connection while a global address is unambiguously assigned to the terminal point of the tunneled connection, which is located at the network end. The network node device forms the terminal point of the tunnel connection, which is located at the network end, if several network elements jointly utilize said tunnel connection, one of the network elements establishing a tunnel connection and forming the terminal point at the network end thereof if said network element requires a global address for executing an application, a time during which said tunnel connection is used exclusively by said one network element while all data is routed through the network node device.
    • 本发明的目的是通过至少一个隧道连接来在外部设备和安装在分组交换网络的网元上的应用之间交换数据。 所述目的通过将每个网络元件连接到作为隧道连接的一部分的网络节点设备来实现,同时将全局地址明确地分配给位于网络端的隧道连接的终点。 网络节点设备形成位于网络端的隧道连接的终点,如果多个网元联合使用所述隧道连接,则网络中的一个建立隧道连接并在其网络端形成终点 如果所述网络单元需要用于执行应用程序的全局地址,则在所有数据通过网络节点设备路由时,所述隧道连接由所述一个网元单独使用的时间。
