[Rack] [Noisebridge-discuss] Omar: Please don't "re-build" the network

Thought I'd chime in here, as I've done a lot of the existing networking.

I'm all for do-ocracy. That's how I built the current network.
That said, at each step, I worked to have a concrete value proposition
for each change. I don't think it's appropriate to make changes for
change's sake.

This makes me think of a common adage at Noisebridge, which is that
"we don't try to preemptively solve problems before they happen".


Omar -- I'm reading over the proposal as it is written up in its
current form (https://www.noisebridge.net/index.php?title=New_Network&oldid=34572),
and I'm trying to get a better understanding of where you're coming
from and why you would like to re-do everything.
In particular, I'm confused by the rhetoric of this sentence: "With
the patch in place, and the WiFi being up regardless of whether or not
any of the switches are online, I proposed we redo ALL the network
infrastructure."
Why would you like to redo all the infrastructure?

In comparing the Logistics and Steps/ToDo List sections with what we
have today, there is very little additions, other than segmentation
between servers, printers/non-human equipment, and human users.
Currently, we have one, big internal subnet and Ethernet broadcast
domain, and it's worked mostly pretty well for us.
However, there are a number of services that are running now that are
not accounted for in the proposed new design.
Some things that come to mind: QoS, WAN flow and SNAT load balancing,
ISP failover, DNAT forwardings for {MC Hawking, Mode-S receiver
hosts}.

Also, why do you want to do away with switches?
They serve a useful purpose in segmenting out the separate Ethernet
broadcast domains, measure aggregate traffic throughput, and
monitoring of link states of infrastructure gear.


So, I have two requests/questions:
- Please explain why segmenting out users, printers, and servers is useful.
- Please propose how to implement the existing network services, so
that service continuity is maintained.

Cheers,
jof
