If my servers are watching Netflix all day I’ve got another problem way
beyond traffic visibility.

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

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.

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 sessi
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.

I use a lot of TEMPer USB Thermometers. Cheap, small, easy to poll.

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
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 man

Is what I use in my cabinets. Has two temp sensors, one internal and one
external. I put the external near the AC cold air output so I can get a
diff and know if the AC is on. SNMP cacti graphs them n
If all that you require is temperature monitoring, I recommend going
through the SNMP MIBs and doing an snmpwalk of your devices to identify the
sensors at the air intake... Unfortunately there are some devices which do
not have air intake sensors, but only a sensor somewhere generally in the
