The document discusses the network setup for the HOPENOC 2018 conference. It details the dark fiber circuit, IP addresses obtained, routers and switches installed, and wireless access point deployment. Setup was delayed due to issues with the circuit not being tagged properly. Once resolved, the fiber runs and network devices were configured rapidly. Wireless traffic was lower than expected but attacks on external servers pushed significant bandwidth. The network performed well despite attacks, and the NOC team and sponsors were thanked.

▸ /48 of IPv6
▸ 2x Arista 7280R Routers from OPAQ (opaq.com)
▸ 112 10G capable interfaces available (copper/fiber)
QSFP ports capable of 40/100G connections
▸ 2 Wireless Controllers with 10G connections
▸ 50 Wireless Access Points
▸ 6 10G PoE switches from Aruba Networks (arubanetworks.com)

HOPE
PRE-CONFIG

4. THURSDAY
SETUP DAY

5. @HOPENOC 2018
SETUP THURSDAY
▸ Circuit didn’t come up!
▸ Couldn’t test in advance
▸ Panel port not tagged
or actually tested end-to-end
▸ RCN lacking connections at two
different PoPs
▸ Couldn’t turn up until ~3pm
▸ To their credit - RCN and HE were
both super responsive in helping to
resolve the issues

6. @HOPENOC 2018
SETUP THURSDAY
▸ Fiber runs completed
▸ 1400 meters of fiber runs in ~12 hours
▸ Ran through 19 floors of the hotel
▸ 4 floors of the hotel in-use + DEMARC
▸ Had to discover a usable path to the lower
level - ended up walking through security’s
back door :)
▸ Turned up 10G to all Wireless PoE switches
▸ Turned up 10G to Radio Statler, and servers for
NYCMesh and Mal.
▸ Completed in record time.

7. @HOPENOC 2018
NOC NOC COLO
▸ 7 devices installed
▸ 3 devices with 10G uplinks
▸ 4 devices with 1G uplinks
▸ Use cases:
▸ RIPE Atlas Sensor
▸ Serving up terabytes of Rainbow Tables
▸ IRC server for 2600net
▸ Radio Statler live stream from the conference!!!
▸ OPAQ appliance for providing secure internet
access for the press
▸ UltraSparc laptop

OBSERVATIONS
▸ Excluding the servers in the NOCNOC,
wireless users only pushed 2 Gbps at
peak :(
▸ Average was 670 Mbps
▸ #pushmorebandwidth —>
▸ Approx. 60% of wireless traffic wasn’t
using any security :(
▸ Most people used Google DNS (default),
small percentage
of users changed their resolvers….
▸ Didn’t notice or care? :)

10. @HOPENOC 2018
OBSERVATIONS
▸ Availability of wireless bandwidth
was pretty good (200-300 Mbps)
▸ People were tweeting good
speed test results even when we
were under attack.
▸ speedtest.net reported our carrier
as “Clark Material Handling” which
apparently now has 5 stars as an ISP
▸ Apparently they manufacture
Forklifts :)

11. @HOPENOC 2018
OBSERVATIONS
▸ Only use case that actually pushed
noticeable bandwidth was a DoS
against servers at packet.net and
AWS.
▸ Pushed ~6 Gbps on average
▸ Caused us to have a total peak
of 7940 Mbps (79% of capacity)
▸ Resulted in packet.net reaching
out to ask what was going on at
HOPE

12. @HOPENOC 2018
OBSERVATIONS
▸ Users were constantly under attack by external bots

13. @HOPENOC 2018
OBSERVATIONS
▸ We ended up pushing a lot of bandwidth… thanks to two users
(<3 nycmesh)…. seriously, push more bandwidth next time.
