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. -- ++ytti
Recommended readings on Network Monitoring and Anomaly Detection.
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. -- Spyridon Mastorakis Personal Website: http://cs.ucla.edu/~mastorakis/ Internet Research Laboratory PhD Computer Science UCLA

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. Regards, M. 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
