ETL is slowing down real-time data analytics

The data transformation tool known as ETL, or extract, transfer and load, is slowing down companies’ ability to do real-time data analysis, costing those companies business opportunities and making their analytics inefficient. That is the result of a survey of 502 IT professionals conducted by IDC on behalf of InterSystems Corp., a high-performance database management vendor. The survey also found that Changed Data Capture (CDC) technology is also slowing companies down and impeding their ability to do real-time data analysis. To read this article in full or to leave a comment, please click here

Did you see my Networkcareer.net Interview?

I recently made an interview with networkcareer.net  I talked with Daniel many things on networking, brief overview of my story , predictions for the future of networking, recommended community platforms for the network engineers and many other things ! This is a new website which provides many good interviews on networking.   There are many good […]

EVPN lab – EVPN-VXLAN to EVPN-MPLS stitching

Last big topic that I need to practice – Data Center Interconnect (DCI).
Fortunately I pretty confident in my skills in the MPLS L3VPN area, so I think I shouldn’t spend much time for this topic.
The most complex DCI option remains – EVPN stitching. In this topic I will show you my example of EVPN-VXLAN to EVPN-MPLS stitching (there is also option of EVPN-VXLAN to EVPN-VXLAN stitching, but configuration should be similar to my example).
EVPN stitching concept is pretty simple – you just need to configure two EVPN instances on each of DC Gateway devices (MX routers) and connect them to each other using Logical Tunnel (lt-) interfaces.
Scheme of my EVPN stitching lab:

Due to time constraints I’ll show you only the upper part of topology – stitching on vMX1 and vMX3 routers. Configurations of vMX2 and vMX4 should be exactly the same as this ones.
So lets see vMX1 routing-instances configuration:

EVPN-VXLAN lab – IRB functionality

Firstly, QFX5100 series doesn’t support EVPN-VXLAN inter-VXLAN routing, so I practice all IRB related topics on vMX devices. vQFXs acts as a simple L2 EVPN gateways.
This post continues the EVPN-VXLAN lab from the previous ones.

BGP Synchronization Rule

Today I am going to talk about one of the basic feature of the BGP named as BGP Synchronization. Your first question : what is BGP Synchronization ? 

BGP Synchronization means that the BGP should not advertise a route until all of the routers within the AS have learned about the route via an IGP. Hope it clears the concept. Let me explain you in another way. It means if you got a ebgp route from the external neighbor via router A (as a assumption) and you want to send it to router B which is connected to another ebgp neighbour, the routes can only be learned to router B once learned by internal routers via IGP protocol.

Let me take an topology and explanation to it and further we can go with the configuration where we will disable the Synchronization as we don't want the traffic to be known to the IGP protocol.

Fig 1.1- BGP Synchronization

As shown in the above topology, if Router C sends updates about network 170.10.0.0 and received by  Router A. Now Routers A and B are running IBGP as shown in the diagram so Router B receives updates about network 170.10. Continue reading

BGP Load balancing ebgp-multihop

Today I am going to talk about the BGP configuration where i will tell you about the load balancing between the two links connecting two service providers via BGP protocol. We have two different methods to achieve this one is use of ebgp multihop command or the other way is to use the ttl security command and both these methods are applicable on the BGP neighbor command.

In this article, We are going to take through the ebgp multihop command on to the neighbours between two service providers. I knew many of you already knew the load balancing concept in the BGP.

In my example, I am taking two serial links between two routers which shares the e-BGP information between them which means each router belongs to the specific AS number. Below is the topology for your reference.

Fig 1.1- use of ebgp multihop

In the above topology, Router A is in AS100 have two serial links connected to Router B which is in AS 200 and for both the links, e-bgp is sharing information.

Below is the configuration on Router A and Router B for your reference. All the IPs and the topology uses here has no relevance Continue reading

Hyper-converged infrastructure – Part 2 : Planning an Cisco HyperFlex deployment

I recently got the chance to deploy a Cisco HyperFlex solution that is composed of 3 Cisco HX nodes in my home lab. As a result, I wanted to share my experience with that new technology (for me). If you do not really know what all this “Hyperconverged Infrastructure hype” is all about, you can […]

Worth Watching: The big four

Worth more than $2.3 trillion combined, the Big Four (Apple, Amazon, Facebook, and Google) continue to grab share from media companies, brands, and retailers. Scott Galloway, Professor of Marketing at the NYU Stern School of Business and Founder of L2, will showcase how the traditional rules of business don’t apply to the Big Four and identify ways that brands and companies can fight back. —Scott Galloway @ YouTube

SHA 2017 – bringing 100 gigabit to the tent

Every 4 years since its start back in 1989, a hacker/security conference takes place in the Netherlands. This summer, the eighth version of this conference, called Still Hacking Anyway 2017 (sha2017.org), will run between the 4th and 8th of August. The conference is not-for-profit and run by volunteers, and this year we’re expecting about 4000 visitors.

For an event like SHA, all the visitors need to connect to a network to access the Internet. A large part of the network is built on Cumulus Linux. In this article, we’ll dive into what the event is and how the network, with equipment sponsored by Cumulus, is being built.

What makes SHA 2017 especially exciting is that it is an outdoor event. All the talks are held in large tents, and they can be watched online through live streams. At the event site, visitors will organize “villages” (a group of tents) where they will work on several projects ranging from security research to developing electronics and building 3D printers.

Attendees will camp on a 40 acre field, but they won’t be off the grid, as wired and wireless networks will keep them connected. The network is designed Continue reading
