    Abstract: Embodiments of the present invention relate to the field of network communications, and provide a method, device, and system for quickly informing a CGN exception, so that a CGN has relatively small load when recreating NAT mapping. In addition, the method is applicable to a commonest application scenario. The method includes: receiving, by an AR, a first packet sent in a unicast manner by a CGN, where the first packet includes information for indicating Restart announce, a source address of the first packet is an address of the CGN, and a destination address of the first packet is an address of the AR; changing, by the AR, the destination address of the first packet to an address of a CPE connected to the AR, to obtain the second packet, where the AR and the CPE are connected by using a Layer 2 network, and the address of the CPE is a multicast address; and sending, by the AR, the second packet. The method is used for quickly informing, after the CGN restarts or undergoes an active/standby switchover, the CPE that an exception occurs, for example, the CGN restarts or undergoes an active/standby switchover.

    Abstract translation: 本发明的实施例涉及网络通信领域，并且提供用于快速通知CGN异常的方法，设备和系统，使得当重新创建NAT映射时，CGN具有相对较小的负载。 此外，该方法适用于最常见的应用场景。 该方法包括：由AR接收由CGN以单播方式发送的第一分组，其中第一分组包括用于指示重新发布的信息，第一分组的源地址是CGN的地址，以及目的地 第一个分组的地址是AR的地址; 通过AR将第一分组的目的地址改变为连接到AR的CPE的地址，以获得第二分组，其中AR和CPE通过使用第2层网络连接，并且该地址 CPE是组播地址; 并通过AR发送第二个分组。 该方法用于在CGN重新启动或进行主备倒换之后快速通知发生异常的CPE，例如，CGN重新启动或进行主备倒换。

    Abstract: An application program may be executed through an Internet protocol (IP) address linkage in an image forming apparatus supporting a peer-to-peer connection. The application program may be executed by performing a method which includes connecting the image forming apparatus to a wireless device through a wireless local area network, driving a soft access point (AP) module of the image forming apparatus so that the image forming apparatus functions as an AP, driving a dynamic host configuration protocol server of the image forming apparatus to allocate a dynamic IP address to the connected wireless device, and linking the dynamic IP address allocated to the wireless device with a static IP address that is preset with respect to the wireless device.

    Abstract: A wireless data card includes: a detecting module, adapted to send a notification message to an executing module after detecting a DNS resolution request sent by a computer and detecting that no user account information exists in the wireless data card; and an executing module, adapted to: receive the notification message sent by the detecting module, send prompt information to the computer so as to prompt a user to input the user account information, and write the input user account information into the wireless data card so that the computer can use the user account information to access the Internet through the wireless data card. A working method of the wireless data card is disclosed. The wireless data card and the working method of the wireless data card avoid the inconvenience caused by loss of the driver CD-ROM, work at a low cost, and require no extra memory.
