Working with ExaBGP 4

One of my goals this year was to spend more time doing Python development so I thought I’d take a break from the MPLS deep dives (no worries – there are still lots more coming) and insert some development type things along the way. One of the opensource projects I’ve used in the past was ExaBGP by the folks over at Exa-Networks. Since then – they’ve released a new version (4) and I’ve been keen to play around with it some more.

The last time I played with ExaBGP was strictly from a testing perspective. This time – I want to focus on some use cases that are closer to real life. Things you might actually do – or at the very least – try. So to start things off – we’re going to once again start with a basic lab that looks like this…

So here we have our 2 friendly end users connected at the head to a small simple network. left_user is attached to an Ubuntu 18 server called ‘bgp_peer’ which is then connected to two other routers (Juniper vMX) and finally our friendly right_user. To start with – we’re going to configure the routers vMX1 and Continue reading

Creating a Net-DevOps environment.

TL;DR : Code is here. Help yourself ? Introduction to the Net-DevOps Container: Recently, Ethan Banks posted a very interesting blog post where he struggled a little bit to set up a Python environment. If I understood correctly, he wanted to increase his skills set in particular with NetDevOps. He fairly pointed that it could be a bit complicated to handle all the dependencies you might need. Based on the fact that you also want to start fresh between projects you want to spend the least amount of time resolving these kinds of issues and maximize your time on something that is valuable: Learn how to Automate or just Automate your network environment. A lot of people are in a [Read More...]

Web performance encompasses a lot of things: page load time, responsiveness for web and mobile applications. But overall, the key element is response times. How quickly can the origin server or the cache fulfill a user request? How quickly can a DNS response reach the client device?

The Cloudflare mission is to help build a better Internet to everyone, and we offer multiple services for boosting the speed and performance of our customers and users. Cloudflare is faster than the competition when it comes to accelerating performance.

How site speed impacts the bottom line

There is a lot of research out there that confirms what many businesses and web developers already know: speed affects revenue. Better web performance means better user engagement and more conversions. Better performance also results in better SEO, driving up overall traffic numbers and increasing lead generation, sales, or ad revenue.

One study by Google and Bing concluded that on average, a two-second delay in a website's page rendering led to a 4.3% loss in revenue per visitor. Another independent study has shown that 1 additional second of load time reduces conversions by 7%.

How does using Cloudflare affect performance?

According to testing from Continue reading
