I'm not sure what the burden refers to, but cost implications to me seem same,
trident HW can do VPLS.
From complexity POV, I don't expect much different development time to write
functioning control-plane to either.

I'm not against Trill, I think Trill, and especially SPB-M are great, now they
just feel too little and 20 years too late. There was no particular reason why
SPB-M couldn't have existed 20 years ago in HW. But perhaps it's good it
didn't, it might have made ethernet 'good enough', that selling MPLS might
have been much more difficult.

Recommended readings on Network Monitoring and Anomaly Detection.

2015-01-17 Thread Spyridon Mastorakis
Dear all,

I am interested in conducting a survey on Network Monitoring and Anomaly 
Detection. I would really appreciate any recommendations for papers/readings 
that would help me on my survey. I am not really familiar with these areas, so 
I would appreciate to receive recommendations about papers/readings that 
elaborate on the basics as well.

Thank you in advance for your time and your recommendations!
Kind regards.

Re: Recommended L2 switches for a new IXP

Last year we installed four 1RU TRILL switches in SIX - see
  http://www.six.sk/images/trill_ring.png

Our experience after 100 days of production is only the best -  TRILL setup
is pretty straightforward and thanks to IS-IS it provides shortest-path 
IP-like routing for L2 ethernet packets over any reasonable topology 
out of the box (without the burden and cost implications of VPLS).
Trident ASICs perform deep packet inspection so ECMP loadbalancing based
on L3 and L4 headers inside TRILL-encapsulated packets works for both IPv4
and IPv6. Port-security is supported on physical ports as well as on LAGs
- and L4 access-lists could be applied at the same time. 

As most 1RU switches are based on Trident ASICs, you just need to pick
a vendor which implements TRILL properly and of course thoroughly test
before deployment. We selected Huawei Cloud Engine 6850 boxes.

 Dear Nanog community
 
 We are trying to build a new IXP in some US Metro areas where we have
 multiple POPs and I was wondering what do you recommend for L2 switches. I
 know that some IXPs use Nexus, Brocade, Force10 but I don't personally have
 experience with these switches. It would be great if you can share your
 experience and recommendations. There are so many options that I don't know
 if it makes sense to start with a modular switch (usually expensive because
 the backplane, dual dc, dual CPU, etc) or start with a 1RU high density
 switch that support new protocols like Trill and that supposedly allow you
 to create Ethernet Fabric/Clusters. The requirements are simple, 1G/10G
 ports for exchange participants, 40G/100G for uplinks between switches and
 flow support for statistics and traffic analysis.
 
 Thank you and have a great day.
 
 Regards
