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

Deep Dive on cli_command for Network Automation

Ansible-Agnostic-Network-Automation

In October Ansible 2.7 was released and brought us two powerful agnostic network modules, cli_command and cli_config. Do you have two or more network vendors within your environment? The goal of agnostic modules is to simplify Ansible Playbooks for network engineers that deal with a variety of network platforms. Rather than having to deal with platform specific modules (e.g. eos_config, ios_config, junos_config), you can now use cli_command or cli_config to reduce the amount of tasks and conditionals within a playbook, and make the playbook easier to use. This post will demonstrate how to use these modules and contrast them to platform specific modules. I’ll show some playbook examples and common use cases to help illustrate how you can use these new platform agnostic modules.

Both the cli_command and cli_config only work with the network_cli connection plugin. For those unfamiliar with the network_cli connection plugin check out this blog post I did last April. The goal of network_cli is to make playbooks look, feel and operate on network devices, the same way Ansible works on Linux hosts.

What can you do with the cli_command?

The cli_command allows you to run arbitrary commands on network devices. Let’s show a simple 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...]

Better business results from faster web applications – Cloudflare is the fastest

Better business results from faster web applications - Cloudflare is the fastest

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

In Southeast Asia, Improving Livelihoods Through Crowdsourcing

The Southeast Asia region is one of the fastest growing regions in the world today. With rich natural resources, it has evolved into a highly industrialized region, inviting investors from all over the world. The riches however, are not enjoyed by all. According to one ASEAN report, close to 36 million of its population are still living below the international poverty line, with 90% of these people in Indonesia or the Philippines.

Realizing that ASEAN’s greatest asset is its people, various initiatives have been carried out to promote community-driven activities and people-to-people interactions aimed at narrowing the income gap in the region. Today, it still remains relevant for ASEAN member states to partner with private organizations to identify and finance poverty eradication programs in order to realize the Sustainable Development Goals and ASEAN Vision 2025.

The Internet Society Malaysia Chapter, through the Beyond the Net Medium & Large Grant programme, and in collaboration with Malaysian’s Ministry of Women, Family and Community Development, the University Utara Malaysia, and the Council of Deans for ICT Eduction (Region IX) Philippines, aims to train 400 women in Malaysia and the Philippines to use the MyHelper crowdsourcing application so that they can Continue reading
