EVPN: The Great Unifying Theory of VPN Control Planes?

I claimed that “EVPN is the control plane for layer-2 and layer-3 VPNs” in the Using VXLAN and EVPN to Build Active-Active Data Centers interview a long long while ago and got this response from one of the readers:

To me, that doesn’t compute. For layer-3 VPNs I couldn’t care less about EVPN, they have their own control planes.

Apart from EVPN, there’s a single standardized scalable control plane for layer-3 VPNs: BGP VPNv4 address family using MPLS labels. Maybe EVPN could be a better solution (opinions differ, see EVPN Technical Deep Dive webinar for more details).

COVID-19 fallout: Q1 enterprise data center sales dip, but public cloud grows

This should come as no surprise, but spending on data-center hardware and software dipped in Q1 and cloud sales grew, but neither as much as you would think.Q1 figures from Synergy Research Group show that spending on enterprise software and hardware shrank globally by a modest 2% year on year to $35.8 billion, with the biggest non-cloud players, such as Microsoft, Dell, HPE, Cisco and VMware, down 4%.[Get regularly scheduled insights by signing up for Network World newsletters.] When it comes to public cloud infrastructure, sales rose 3% to $9.66 billion year on year. The top vendors were Chinese ODMs that hyperscalers like: Dell, Microsoft, Inspur and Cisco.To read this article in full, please click here

4 years on air.

Hello my friend,

Traditionally in the beginning of June (5th of June to be accurate), we celebrate the anniversary of our blogging. And in this year it is already 4 years, since we started in 2016!

In terms of the absolute numbers, we have crossed the mark in 100 posted blogs! Hurray! And we were marked as Cisco Champion 2020 one more time! Also Hurray!

Let’s reflect what has happened global as well…

Live automation training

The biggest new introduction is the live online network automation training. Years of real practical experience of implementing and automating network solutions for service provider and data centres across Europe and North America are now available for you. Just join our network automation training in this run or in any next and learn:

  • Why to automate?
  • How to automate?
  • What is the toolkit (YANG, XML, YAML, JSON, Protobuf, NETCONF, RESTCONF, gNMI/gRPC, VS Code, Atom, POSTman, Python, Ansible, Linux, Docker and many others)?
  • How do different vendors behave (Cisco, Nokia, Arista, Cumulus)?

GitHub projects

There were multiple mini-series of the blogposts supported by the code at the GitHub:

Measuring the Core

This last week I was a guest on the TechSequences podcast with Leslie and Alexa discussing the centralization of the routed infrastructure in the ‘net. When that episode posts, I’ll cross post it here (but, of course, you should really just subscribe to their podcast, as they always have interesting guests—I’ll have Leslie and Alexa on the Hedge at some point, as well). The topic is related to this post on CircleID about the death of transit, which was a reaction to Geoff Huston’s article on the death of transit some time before.

All that to say… while reading through some research papers this week, I ran into a recent (2018) paper where Carisimo et al. try out different ways of measuring which autonomous systems belong to the “core” of the ‘net. They went about this by taking a set of AS’ “everyone” acknowledges to be “part of the core,” and then trying to find some measurement that successfully describes something all of them have in common.

The result is the k-metric, which measures the connectivity of an AS’ peers. If an AS has peers who are just as connected as they are, then k-metric is high. Otherwise, the k-metric Continue reading

How TripleLift Built an Adtech Data Pipeline Processing Billions of Events Per Day

 

This is a guest post by Eunice Do, Data Engineer at TripleLift, a technology company leading the next generation of programmatic advertising.

What is the name of your system and where can we find out more about it?

The system is the data pipeline at TripleLift. TripleLift is an adtech company, and like most companies in this industry, we deal with high volumes of data on a daily basis. Over the last 3 years, the TripleLift data pipeline scaled from processing millions of events per day to processing billions. This processing can be summed up as the continuous aggregation and delivery of reporting data to users in a cost efficient manner. In this article, we'll mostly be focusing on the current state of this multi-billion event pipeline.

To follow the 5 year journey leading up to the current state, check out this talk on the evolution of the TripleLift pipeline by our VP of Engineering.

Why did you decide to build this system?
