摘要:
Embodiments of the present invention provide an address assignment method, a device, and a system. The method is applicable to a network having a broadband remote access server BRAS, where the BRAS is set with carrier grade net address translation CGN, the method including: detecting, by the BRAS, that the locally set CGN fails; receiving, by the BRAS, an access request sent by a terminal; and assigning, by the BRAS, a public IP address to the terminal. In the embodiments of the present invention, when the CGN fails, terminal traffic transfer is not required, thereby shortening terminal service recovery time when the CGN of the BRAS fails, and lowering costs.
摘要:
A filtering method, a filtering system, and network equipment are provided by the present invention. The method includes: intercepting a request packet sent by a user terminal to an Internet server and extracting Uniform Resources Locator (URL) information from the request packet; determining a security level corresponding to the URL information according to the URL information; and processing the request packet according to the security level. Therefore, the problem that the installation of antivirus softwares in the user terminal occupies memory space and CUP resources and the problem of the risk of being bypassed by malwares are solved, which effectively prevents malwares from spreading and attacking, reduces the threat to user terminals from malwares, and improves the network security and user experience.
