Firewalls are extensively used in internet for providing security and privacy. A firewall basing on its policy checks every incoming packet and decides whether to accept or decline the packet. The firewall policy became major factor in improving the quality of the network performance. This paper studies inter-firewall optimization across administrative domains for the first time. The important technical challenge is that firewall policies cannot be shared across domains because a firewall policy contains confidential information and even potential security holes, which can be exploited by attackers.
