防火墙技术使用在集聚层设备,首要保护接入用户,包括阻遏用户的非授权业务,阻遏外部对接入用户的不合法访问等;ASPF技术可以保护接入用户和网络设备本身免受恶意攻击,但是ASPF技术的选用会带来设备功能的下降;另外在城域数据核心一般选用专用防火墙。

(Firewall technology is used in aggregation layer devices to protect access users first, including blocking unauthorized services of users and preventing illegal access to access users from outside; ASPF technology can protect access users and network devices themselves from malicious attacks. However, the selection of ASPF technology will bring about the decline of equipment functions; in addition, a dedicated firewall is generally used in the metropolitan area data core.)
