    • A routing method with routing algorithms applicable to a one-level hierarchical network, including a first algorithm in which a shortest one among all paths established in association with one destination is selected, a second algorithm in which the first method is conducted in a distributed fashion to achieve a fast routing, and a third algorithm in which any one of paths established in association with one destination may be selected as a shortest path when the QoS value calculated in association therewith is more optimum than a required reference QoS value, for preventing problems caused by errors at the single path. The method also provides algorithms that are modified versions of the second and third algorithm for the multi-level hierarchical network. Accordingly, the method is advantageous in that users can select an algorithm, most suitable for the system environment, from the above algorithms.
    • 一种具有适用于一级分层网络的路由算法的路由方法,包括选择与一个目的地相关联的所有路径中的最短路径的第一算法,其中第一种方法以分布式方式进行的第二算法 以实现快速路由,以及第三算法,其中当与一个目的地相关联地建立的任何一个路径可以被选择为当与其相关联地计算的QoS值比所需参考QoS值更优化时作为最短路径,以防止问题 由单路径错误引起。 该方法还提供了用于多级分层网络的第二和第三算法的修改版本的算法。 因此,该方法的优点在于,用户可以从上述算法中选择最适合于系统环境的算法。

    • Disclosed is an apparatus for establishing an IP level connectivity between internet access terminals using a service gateway including a first ISP network connected at one end thereof to a first terminal having an inherent IP address and at the other end thereof to an internet network, the first ISP network including a service gateway for executing authentication of a subscriber of the first terminal in accordance with a service request of the first terminal and communication with other service gateway; a second ISP network connected at one end thereof to the internet network and at the other end thereof to an ATM network to which a second terminal having no inherent IP address is connected, the second ISP network serving to establish an IP level connectivity between the first and second terminals if the first terminal requests connection to the internet network for service use along with the second terminal. The present invention also proposes a service providing method which includes a service providing procedure for establishing an IP level connectivity between a terminal connected to an internet and a dial-up terminal not connected to the internet while also having no inherent IP address.
    • 公开了一种用于使用包括在其一端连接到具有固有IP地址的第一终端的第一ISP网络并且在另一端连接到互联网的服务网关来建立互联网接入终端之间的IP级连接的装置,所述第一 ISP网络,包括根据第一终端的服务请求执行第一终端的用户认证的服务网关,并与其他服务网关通信; 第二ISP网络,其一端连接到互联网,另一端连接到没有固有IP地址的第二终端连接到的ATM网络,第二ISP网络用于建立第一 以及第二终端,如果第一终端请求连接到互联网以便与第二终端一起服务使用。 本发明还提出了一种服务提供方法,其包括用于在不连接到互联网的终端和不连接到互联网的拨号终端之间建立IP级连接的服务提供过程,同时也没有固有的IP地址。
