BGP+SPF for Hyperscale/Massively Scale Datacenter Deployment
BGP+SPF Imagine we replace BGP best path selection decision with SPF. BGP+SPF exactly does that. In this post, I will explain why we are looking for alternative protocols for Massively Scale Datacenter.
Although there is no exact answer how many devices should be in the datacenter so datacenter can be considered Massively Scale, but we know 10.000 Racks are not uncommon in these type of datacenter and each rack, when BGP is used as a transport, gets it’s own unique AS number.
Before I explain BGP+SPF, let’s understand why traditional , very well know, OSPF or IS-IS are not used in these type of datacenter.
Answer is scalability. OSPF and IS-IS are chatty protocols and flooding aspect of these protocols are just not suited to very densely meshed connectivities. Yes, these datacenter run on CLOS topology and CLOS is densely meshed topology.
Also, we want to have wide ECMP in these type of datacenter, meaning, between the TOR, Leaf and Spine devices, there are so many equal cost path and we want to utilize them all. OSPF and IS-IS will be limited to number of ways of ECMP.
BGP is very well suited protocol which provides very wide ECMP Continue reading
Remote Work Isn’t Just Video Conferencing: How We Built CloudflareTV
At Cloudflare, we produce all types of video content, ranging from recordings of our Weekly All-Hands to product demos. Being able to stream video on demand has two major advantages when compared to live video:
- It encourages asynchronous communication within the organization
- It extends the life time value of the shared knowledge
Historically, we haven’t had a central, secure repository of all video content that could be easily accessed from the browser. Various teams choose their own platform to share the content. If I wanted to find a recording of a product demo, for example, I’d need to search Google Drive, Gmail and Google Chat with creative keywords. Very often, I would need to reach out to individual teams to finally locate the content.
So we decided we wanted to build CloudflareTV, an internal Netflix-like application that can only be accessed by Cloudflare employees and has all of our videos neatly organized and immediately watchable from the browser.
We wanted to achieve the following when building CloudflareTV:
- Security: make sure the videos are access controlled and not publicly accessible
- Authentication: ensure the application can only be accessed by Cloudflare employees
- Tagging: allow the videos to be categorized so they can Continue reading

Introducing the Internet Society’s 2019 Impact Report
In these uncertain times we know the Internet is so much more than a tool. It’s a way for people to stay connected, informed, and educated. It shortens distances, spurs innovation, and fosters social and economic development. It empowers us and frees us.
It is a lifeline.
Yet, nearly 50% of the world still remains unconnected – and globally the Internet faces threats, each with the power to undermine the core of its existence. Now more than ever we must ensure the Internet remains open, globally connected, and secure.
The world is counting on it.
As we looked back at our work in 2019, an inspiring theme emerged: a global society driven by the idea that the Internet should be a resource for all, and persevering against odds to make this vision a reality. This society recognizes the Internet’s power as a way to stay in touch, to empower, to enable, and to create. Collectively, we are not just helping to bridge the digital divide, we are taking action to ensure the Internet remains resilient and trusted – a force for good.
Our 2019 Impact Report highlights the work of the Internet Society – our Chapters, Organization Members, individual members, Continue reading

SFMIX San Francisco shelter in place
The traffic trend chart above from the San Francisco Metropolitan Internet Exchange (SFMIX) shows the change in network traffic that has resulted from the shelter in place order. Peak traffic has increased by around 10Gbit/s (a 25% increase) and continues throughout the day (whereas peaks previously occurred in the evenings).
The SFMIX network directly connects a number of data centers in the Bay Area and the member organizations that peer from those data centers. Peering through the exchange network keeps traffic local by directly connecting companies with their employees and customers and avoiding potentially congested service provider networks.

Using Cloudflare Gateway to Stay Productive (and turn off distractions) While Working Remotely
This week, like many of you reading this article, I am working from home. I don’t know about you, but I’ve found it hard to stay focused when the Internet is full of news related to the coronavirus.
CNN. Twitter. Fox News. It doesn’t matter where you look, everyone is vying for your attention. It’s totally riveting…
… and it’s really hard not to get distracted.
It got me annoyed enough that I decided to do something about it. Using Cloudflare’s new product, Cloudflare Gateway, I removed all the online distractions I normally get snared by — at least during working hours.
This blog post isn’t very long, but that’s a function of how easy it is to get Gateway up and running!
Getting Started
To get started, you’ll want to set up Gateway under your Cloudflare account. Head to the Cloudflare for Teams dashboard to set it up for free (if you don’t already have a Cloudflare account, hit the ‘Sign up’ button beneath the login form).
If you are using Gateway for the first time, the dashboard will take you through an onboarding experience:
The onboarding flow will help you set up your first location. A location is Continue reading
What is Healthy Risk Taking When it Comes to Your Career?
To move ahead in your career and achieve the goals you set for yourself at the start of your career is going to involve taking some risks. However, not every risk you take in your career is a wise and healthy risk that will lead to the rewards you are seeking. Before you take any risk in your career, you first need to define healthy risk taking behavior.
What is Healthy Risk Taking Behavior?
Healthy risk taking behavior can be defined as risk taking that is planned and calculated after weighing the pros and cons of taking that risk. You can also define healthy risk taking behavior as taking a risk to reach your career goals, knowing that taking that risk can lead to failure, but can also lead to great success.
Risk taking helps you to overcome your fear and take action in the pursuit of a higher goal. When engaging in healthy risk taking, there are some things you need to consider.
Possible Outcomes
What will be the possible outcomes of taking certain risks? For example, will changing from one company to another result in getting you a step closer to your career goals, or will the outcome Continue reading
