    • An asymmetrical network for coupling customer-premises Internet hosts such as personal computers to the Intemet. The head end ofa CATV system has a high-bandwidth connection to the Internet. The down link connecting the personal computers to the Intemet is the cables provided by the CATV system; the up link is a telephone connection to the head end. A router is connected to the down link by means of an RF modem, to the up link by means of an analog modem, and to a LAN which is connected to the Pcs. The router routes IP packets for the hosts that are received on the CATV cable to the hosts via the LAN; it routes IP packets from the hosts that are destined for the Internet to the head end via the telephone line. The asymmetrical network conserves IP addresses and addresses on the CATV cable by dynamically allocating the IP addresses for an RF modem's hosts and an address on the CATV cable for the RF modem in response to a request made by the RF modem via the telephone line. It further saves IP addresses by assigning a non-unique IP address to the router for use inside the LAN. When the CATV system fails, the asymmetrical network automatically begins to use the telephone line as both the up link and the down link, and when the CATV system is restored, the asymmetrical network automatically returns to using the CATV cable as the down link and the telephone line as the up link. A further feature of the asymmetrical network is that the head end components and the RF modem have IP addresses, so that standard TCP/IP protocols can be used to control the asymmetrical network.
    • 不对称的网络连接的客户驻地因特网主机:如个人计算机到因特网。 头端OFA CATV系统具有高带宽连接到互联网。 连接个人计算机到因特网的下行链路是由CATV系统提供的电缆; 上行链路是电话连接到前端。 路由器连接到通过RF调制解调器的方式在下行链路,通过模拟调制解调器的手段上行链路,以及到LAN的所有其连接到PCS。 为主机,路由器路由IP数据包也都在CATV电缆通过局域网内主机接收到的; 从它的主机路由IP数据包都被发往Internet通过电话线的头端。 的非对称网络通过在RF调制解调器的主机动态分配的IP地址,并且响应于通过经由电话线路上的RF调制解调器做出的请求,以解决用于RF调制解调器CATV电缆上CATV电缆节省IP地址和地址。 它通过路由器在局域网内使用分配非唯一的IP地址,可以节省更多的IP地址。 当CATV系统出现故障时,非对称网络自动开始使用电话线作为两个上行链路和下行链路中,并且恢复CATV系统的情况下,非对称网络自动返回到使用CATV电缆作为下行链路和 电话线的上行链路。 非对称网络的进一步的特征是做的头端部件和RF调制解调器具有IP地址一样,标准TCP / IP协议可以用于控制非对称网络。

    • A computer-implemented method performed by a network element for authentication, authorization, and accounting based on a username, the method comprising the steps of: receiving a first request at the network element from a client device for a source Internet Protocol (IP) address, the request including an identifier that is a Media Access Control (MAC) address; transmitting a second request to a RADIUS server to retrieve a context, wherein the request includes as the username a subscriber identifier automatically generated by the network element based on the identifier that is the Media Access Control (MAC) address; if the first request is an initial communication by the client device with the network element, redirecting the client device to a website to allow for a selection of a service from multiple services, wherein different contexts within the network element are associated with the different services, wherein the context for the selected service is entered into a subscriber record that is accessible according to the username and that is stored in the RADIUS server such that the network element can retrieve the context according to the username; receiving a response from the RADIUS server; dynamically assigning to the client device, from the context retrieved, an IP address that is not currently assigned from that context; establishing an active subscriber session for the client device based on the IP address; and causing an accounting update to reflect the active subscriber session.
    • 一种由网元执行的用于认证,授权和计费的计算机实现的方法,所述方法包括以下步骤:从客户端设备接收源IP地址(IP)地址的网元的第一请求 该请求包括作为媒体访问控制(MAC)地址的标识符; 向RADIUS服务器发送第二请求以检索上下文,其中所述请求包括作为所述用户名的基于由所述媒体访问控制(MAC)地址的所述标识符由所述网元自动生成的订户标识; 如果所述第一请求是所述客户端设备与所述网元的初始通信,则将所述客户端设备重定向到网站以允许从多个服务中选择服务,其中所述网络元件内的不同上下文与所述不同服务相关联, 其中所选择的服务的上下文被输入到可以根据用户名访问并且存储在RADIUS服务器中的用户记录,使得网络元素可以根据用户名检索上下文; 从RADIUS服务器接收响应; 从所检索的上下文中向所述客户端设备动态分配当前未从所述上下文分配的IP地址; 基于IP地址为客户端设备建立活动用户会话; 并引起会计更新以反映活动订户会话。
