Reliance Jio Has Luxury of Building a Greenfield SDN Network
The Indian mobile operator is building a software-defined network (SDN) from scratch using Cisco, Samsung, and other vendors, along with cherry-picked open source code.

Andy sent me this question:
I'm currently playing around with BGP & VXLANs and wondering: is there anything preventing from building a virtual IXP with VXLAN? This would be then a large layer 2 network - but why have nobody build this to now, or why do internet exchanges do not provide this?
There was at least one IXP that was running on top of VXLAN. I wanted to do a podcast about it with people who helped them build it in early 2015 but one of them got a gag order.
Read more ...This article is the second post in a series that is all about EVPN-VXLAN and Juniper QFX technology. This particular post is focussed specifically on EVPN Anycast Gateway and how to verify control plane and data plane on Juniper QFX10k series switches.
In my first post, I explained how to verify MAC learning behaviour in a single-homed host scenario. This time we’re going to look at how to verify control plane and data plane when using EVPN Anycast Gateway. As explained in my previous post, verifying and troubleshooting EVPN-VXLAN can be very difficult. Especially when you consider all the various elements that build up the control plane and data plane.
So, what is EVPN Anycast Gateway?
During the initial conception of EVPN L3 gateway, it was assumed that all PE devices would be configured with a Layer 3 interface (IRB) for a given Virtual Network. It was also intended that all IRB interfaces would be configured with the same IP address thus creating a redundant gateway mechanism.
This worked great until EVPN-VXLAN came along and crucially the hardware that was being deployed at the leaf layer no longer provided support for VXLAN L3 Gateway (IRB). As a result, Anycast Gateway, or Virtual Gateway Continue reading
When Nvidia co-founder and chief executive officer Jensen Huang told the assembled multitudes at the keynote opening to the GPU Technology Conference that the new DGX-2 system, weighing in at 2 petaflops at half precision using the latest Tesla GPU accelerators, would cost $1.5 million when it became available in the third quarter, the audience paused for a few seconds, doing the human-speed math to try to reckon how that stacked up to the DGX-1 servers sporting eight Teslas.
This sounded like a pretty high price, even for such an impressive system – really a GPU cluster with some CPU …

At the Open Networking Summit, AT&T said DANOS was critical to the company as it deploys 60,000 white boxes and transforms its network to deal with the onslaught of traffic and the advent of 5G.
It has happened time and time again in computing in the past three decades in the datacenter: A device scales up its capacity – be it compute, storage, or networking – as high as it can go, and then it has to go parallel and scale out.
The NVLink interconnect that Nvidia created to lash together its “Pascal” and “Volta” GPU accelerators into a kind of giant virtual GPU were the first phase of this scale out for Tesla compute. But with only six NVLink ports on a Volta SXM2 device, there is a limit to how many Teslas can …
