Arbor vs Narus comparison?
by andy lam 19 Dec '08

19 Dec '08

Recently I've been searching for something that is comparable to Arbor to see what else is out there. Someone suggested Narus. Anyone out there have an opinion regarding the 2 applications and their differences? Or another application that is worth noting? I am currently using Arbor Peakflow for Netflow analysis against my peering/transit traffic and their Security suite to identify DoS, etc at the edge. Feel free to contact off-list. Thanks

Folks, Any Global Crossing SOC folks here? We've had a simple DoS attack targeting one of our nodes connected to Global Crossing but have literally spent 3 hours on the phone with Global Crossing support attempting to get someone with a clue as to how to implement a simple ACL on their edge router to deal with this. If there's anyone here who can assist, please contact me off list. Regards, Stefan Fouant: NeuStar, Inc.

DDOS - How much is "too much"?
by Tuc at T-B-O-H 17 Dec '08

17 Dec '08

Hi, I have a client who prior to me settled into a non-carrier-neutral facility. They were approached this week for "DoS/DDoS protection" which they could buy in X Mb/s, 2xX Mb/s or 4xX Mb/s scrubbing solutions. Maybe I've been out of the running my larger Managed Server Hosting Company too long, but wasn't the "non-elegant" solutions something ISPs just "did"? Was it only DoS, and when it comes to DDoS they tell you its just too much to handle. And blocking how many netblocks does an ISP consider "too many" before it tells the client there is only so much it can do for them? Do people tell/give clients their own solutions? (Like Zebra boxes that'll inject BGP into their site) They wanted me to come up with 3 reasons FOR the service, 3 against, and what I felt was a fair market value for this. I just need to know if people still did that type of stuff for each other or if everything costs nowadays.... Thanks, Tuc/TBOH

e300 vs mx240 for border router ?
by Leslie 17 Dec '08

17 Dec '08

Hey nanog-izens So for routers that are touching our transit and (hopefully soon) future peering, we're looking at both the force10 e300's and juniper mx240's. The e300's are cheap but I have heard some rumors/talk of falling over when it has to deal with large numbers of prefixes and routes? The mx240's are nice but the cost difference is enormous. Does anyone have experience with e300's running into issues with large routing tables? Are there any tricks/tips that work around any issues (if they exist?) Thanks in advance Leslie

Thanks to all who replied. Due to ease of deployment I will probably go with the Cent)S based server and tools and modify things as I need it afterwards.
