目前接入网设备管理地址占用大量公网IPv4(因特网协议版本4)地址资源,影响今后公网业务发展;接入网设备安全控制能力较弱,直接暴露在公网上,存在诸多安全隐患。宽带、iTV(互动电视)业务的大发展,使得IPv4地址资源日趋紧张。介绍了为应对IPv4地址枯竭,采取的针对接入网设备管理IP地址的私网改造方案,可望增加可用公网地址。
Currently, the management address of the access network device occupies a large amount of address resources of public network IPv4 (Internet Protocol Version 4), which affects the development of public network services in the future. The access network device has weak security control capability and is directly exposed on the public network. There are many security risks. Broadband, iTV (interactive television) business development, making IPv4 address resources increasingly tight. Introduced in order to deal with the depletion of IPv4 addresses, access network management equipment for the IP address of the private network transformation program, is expected to increase the available public network address.
