If my servers are watching Netflix all day I’ve got another problem way beyond traffic visibility. On July 12, 2017 at 12:37:48 PM, valdis.kletni...@vt.edu ( valdis.kletni...@vt.edu) wrote: On Wed, 12 Jul 2017 11:03:50 -0700, ShaColby Jackson said: > I know solutions like Kentik do a lot more

Testing methodology for the Chinese quantum satellite link?

Does anyone who understands quantum networking better than I do have an opinion on the testing methodology that the Chinese team used to confirm entanglement? I guess, more specifically, my question is: when they say that they got 911 positive results out of “millions” of attempts, does this

RE: noction vs border6 vs kentik vs fcp vs ?

I have 3 different well-known caches local to my network... 45% of my subscriber traffic hits the caches 55% of my subscriber traffic hits the internet uplinks I love my caches, but I REALLY love the Netflix cache. It's a huge savings on my internet uplinks. -Aaron

RE: 10G MetroE 1-2U Switch

Hi Erik, as a follow-up to this email from back in April...previously I hadn't yet tested any qos things on the ACX5048. Now I have tested some policing and seems to be working thus far in the lab. I am policing at the unit (subinterface) level to I can accomplish per-vlan/per-unit policers. I

Re: BGP peering question

Speaking as a small ISP with 10 to 20 Gbps peak traffic. We are heavy inbound as a pure eyeball network. We use the route servers. We only maintain direct BGP sessions with a few large peers. Think Google, Netflix, Akamai etc. The reason for this is simply administrative overhead. Every BGP

Re: BGP peering question

If you develop a well tuned process for creating BGP sessions and even a moderate system for monitoring not the individual sessions, but meaningful traffic events on your network, then, maintaining a large number of peers and a promiscuous peering policy is not such a daunting process. As a

Re: Temperature monitoring

Weathergoose by IT watchdogs. 1U rackmount devices with very shallow depth of about an inch or two. Sensors are cheap, varied, and you can daisychain dozens of them together. So one server box can monitor entire row of racks. Loads of other features too for notification, escalation, and SNMP

Re: Temperature monitoring

We have Sensaphones (sensaphone.com) in remote offices. We use IMS-4000s. They are a 1RU box with RJ45 jacks on the front. You can run CAT-5 to where you want to monitor something, and stick a module on the end of the cable. They have temp, humidity, generic NO/NC sensors, power sensors to

All, We had an issue with a DC where temps were elevated. The one bit of hardware that wasn't watched much was the one that sent out the initial alert. Looking for recommendations on hardware that I can mount/hang in each cabinet that is easy to set up and will alert us if temps go beyond a
