firewall capacity expansion for DDOS protectionI have to expand firewall capacity (max session) for ddos protection-L3
In my opinion, firewall is vulnerable to a session based attack ( like HTTP GET Flooding)
For DDOS protection.. I consider three items 1. remove the L4 in front of firewall (like firewall load balancer) 2. firewall active/active ( multiple context is not used - Cisco engineer is not recommendation) 3. Distributed traffic
Four kinds of technology - L3 based load balancing ( traffic desctibution using L3) - source ip based routing ( PBR ) - switch stack - dns load balancing
i attached file ( current firewall & nework architecture and new architecture )
I have a few guestions 1. is new network architecture possible..? 2. additional issues..?
