Re: $110,000 for Gated Source Code

  • From: Alex P. Rudnev

I had a long  (2 years) experience with GATED-based routers, 
routers, etc. What did we learn from this experience (we just have a few 
PC based routers now, but it's due to historical reasons and some 
compatibility problems for old customer's unix-based routers), is the 
next idea. Let's you have a few different router vendors (I mind software 
vendors) in the global IP network, and both have 1 bug in their software.
In case if there is 99 Vendor-1 routers, and 1 Vendor-2 router, the bug 
in Vendor-1 software cause the total network to have a problems, will be 
fixed in a few days, and moreover, if the network environment (I mean 
routing tables, AS pathes etc etc) appear in one point of the network, it 
faile down surrounded routers and you should not be affected by this bug 
and this network circumstances.

But if this circumstances cause the Vendor-2 router to fail down, and 
they appear at some point of the network, all Vendor-2 routerss should 
be affected by this bug because they are connected to the Vendor-1 based 
network don't affected by this circumstances.

We saw this a lot of times for GATED (fortunately gated was used by Merit 
and this forced them to fix the bug quickly; moreover some part of the 
network have been isolated by Merit from us). We saw this for Wellfleets 
sometimes. We never saw this for Cisco because any network influence 
caused CISCO to crash was isolated not far from the origin.

I do not defence CISCO and do not blame Wellfleet or someone else; I only 
tell about our experience. If your use rarely used routing program, you 
are affected by the network splashes from the any point of 
total Internet; if you use the same router as your peers and/or upstream 
provider, you are isolated from such splashes (if this splash cause your 
router to fail, it cause your peer/ISP's router to fail before).

This is the major reason why CISCO totally win the ISP market for now. 
And this is why a lot of vendors prefere GATED to some third-party 
software. This does not mean it's excellent. But it makes more difficult 
for the network admins to choose new hardware if it's based on the 
absolutely new software. 

I'd like to prefere the flame about Wellfleet/Cisco/etc... But to prevent 
CISCO's monopoly or MS monopoly, you should understand better why did 
this monopoly appeared.
