This paper discussed the impact of ATM on firewalls. These differences have a greater impact on packet screens than application level firewalls, as they are more dependent on the underlying network than application level firewalls. The highly scalable ATM technology raises throughput problems for both packet screens and proxy servers. This emphasizes the necessity for the parallel firewall concepts we have introduced, which overcome the throughput bottleneck.
Parallel firewalls can provide scalable solutions for upcoming high-speed networks.
Prototypes of parallel firewalls will be developed in further research.
