This AusNOG presentation touches upon the topic: http://www.ausnog.net/images/ausnog-05/presentations/7-2-stateofdanger.pdf heh, Until IPv6 is a mainstream, I don't think wireless companies (and soon wireline) have much choice on CGN. I believe there are plenty of CGN products that handle as much or more pps than my Juniper MX960 does. My last DDOS killed the egress pps on 2 of my NSP transits. Neither could send 2Mpps of traffic to me (ie, neither was line rate at 43bytes). I'm confused as to the 6to4 gateway state. Last I checked, all my 6to4 is stateless. My load balancers are also stateless. IPS can be deployed sidelined with hardware packet mirroring and remote updates to router ACLs. I recognize that ISPs may not keep DDOS in mind and reduce state when possible, but there is current tech that can limit state and still deploy the same services. CGN is the exception to the rule, and I've yet to see a way around it in a depleted IPv4 Internet (but as stated, most CGN is designed to handle state to the same performance levels as current router tech).

I probably should've used a different term. My load balancers are also stateless. Most are not, or aren't configured to be so (i.e., most seem to be set up to handle the outbound server-to-client comms, too). I see them go down like tenpins in trivial DDoS attacks all the time. --- Roland Dobbins rdobb...@arbor.net // http://www.arbornetworks.com The basis of optimism is sheer terror. -- Oscar Wilde
Manage an enterprise network? Please fill out my survey - for Science! :-)
Hello! My name is Justine and I am a graduate student at UC Berkeley (http://cs.berkeley.edu/~justine). I'm doing a research project on middlebox appliances such as proxies, WAN optimizers, and firewalls. Middlebox appliances are any networking-related hardware other than routers and switches. I'd like to learn a little bit about how middleboxes are used in real world deployments in enterprises. Vendors often engage in surveys of this type - but the research community knows less than we'd like to about typical concerns in an enterprise network. If you work on network management in an enterprise, I'd love to hear about your experiences through this survey: https://docs.google.com/spreadsheet/viewform?hl=en_USformkey=dHo1NGZ3eU04SlBaSnNsSlBYZGNYSlE6MQ#gid=0 Some promises: (1) If you give me your email address, I will not give it to anyone else, nor will I add you to any annoying mailing lists. (2) If you mention the name of your organization, I will not share it with anyone else. (3) If I publish any data from this, statistics will be reported in aggregate. (4) I will not share the raw data from this survey with anyone other than my advisor, Professor Sylvia Ratnasamy (syl...@eecs.berkeley.edu). Feel free to skip questions and please provide approximate answers if you have them. Finally, to thank you for your time, we'll enter you in to a lottery for a $100 Amazon gift card; we'll select two people to win and contact them on November 16. Thank you! If you have any questions or concerns, please contact me. Justine PS: The survey is here!
