Dear Group, Security issues come over to me in a certain case of mine: how to prevent an ISP and IDC from being attacked by DDoS? ACL CAR in exit routers may be bringing some impack on performance? Firewall may be having some throughput problem? Any advice for this kind of issues,I am very appreciated.
