RESEARCH 》 How to check a website using CDN ?

If you are new to CDN Technology, you can read the Introduction of CDN (Content Delivery Networks or Content Distribution Networks) over HERE.

Using a CDN for a website is a always suggested based on the popularity of your website. But do you know how to check if a website is using a CDN ?

Here is how you can check quite easily.

Lets take for example Facebook. Open the Facebook website in your browser.
1-research-how-to-check-a-website-using-cdn-facebook

Do right-click and select the “View Page Source” option in the menu:
2-research-how-to-check-a-website-using-cdn-facebook-view-page-source

Now search for keywords such as “cdn”, “edge”, etc. You can find the website resources (such as scripts/images/etc) should be pointing to alternative links as shown below:
3-research-how-to-check-a-website-using-cdn-facebook-page-source

In this case Facebook contains the resources with URLs pointing to CDN hosted locations. As you can see it has the location “m-static.ak.fbcdn.net”. This stands for: Static Akamai Facebook CDN. So this is a clue that Facebook is majorly hosted on Akamai CDN.

But one should also understand since Facebook is so massive, Facebook may/will contain its own CDN (or cloud sort of) infrastructure. But if this goes beyond a massive scale, certainly they can get outside world CDN subscriptions as in this case they got via Akamai.

Let us see another example such as the website ComputerWorld online magazine.
4-research-how-to-check-a-website-using-cdn-computerworld-page-source

In this case ComputerWorld is using the Edgesuite.net. Edgesuite.net is run by Akamai Technologies more specific for AD content. So once again we can see how a website uses a CDN Service.

In the case of Linkedin, it uses the Limelight CDN service/vendor. You can see the resource URLs containing static.licdn.com.

Multi-dimensional (Multi-universe) Internet Technology - A Proposal ↗
Saturday' 13-Mar-2021
Currently what we have is a single homogeneous (sort of) WWW Internet. Which we can consider as a single-dimensional network. What I propose is that we can create complete independent multiple Internets with each Internet having its own IP-address space, Domain namespace and an authority to manage Domain names. And these networks/Internets can be entirely IPv4 only based or IPv6 only based.

Raspberry Pi as a Networking Device ↗
Saturday' 13-Mar-2021
Raspberry Pi is often used as a single board computer for applications such as IoT, hobby projects, DIY, education aid, research and prototyping device. But apart from these applications Raspberry Pi can be used for real-world applications such as in making a full-fledged networking devices. Raspberry Pi is a single board ARM based hardware which is why it is also classified as ARM based SoC. Since it is ARM based it is highly efficient, tiny form-factor and lower in power consumption with moderate computational power. This will allow it to work several hours on emergency battery backup power supply such as low-cost domestic UPS and or some renewable energy source, which is a prerequisite for a typical networking device.

Saturday' 13-Mar-2021
TrueBench is an unique open-source benchmarking system in which the core system performance and efficiency parameters are measured at extreme high resolution in the order of several million/billion µ-seconds for a given specific task. TrueBench is a part of The TOFFEE Project research.

TOFFEE-DataCenter :: Features Supported ↗

TOFFEE-DataCenter WAN Optimization software development - Update: 13-Aug-2016 ↗
Saturday' 13-Mar-2021
Earlier the TOFFEE is intended to work on IoT devices, Satellite Networks, branch office/SOHO deployments. In most cases the users may deploy just one or couple of TOFFEE devices per site. But in the case of TOFFEE-DataCenter, users can scale-up deploying the same in multiple servers in a sort of distributed cluster computing scenario. Besides the core TOFFEE-DataCenter components (such as packet processing engine/framework), I need to do lot of changes in its Graphical User Interface (GUI) too to address these new requirements.

TOFFEE with Hardware Compression and Decompression Accelerator Cards ↗
Saturday' 13-Mar-2021
You can build a basic TOFFEE WAN Optimization hardware completely in software layer (i.e its networking data-plane and control-plane). And if you are a product manufacturer you can make commercial WAN Optimization products with TOFFEE with software layer alone. And if you choose to improve its performance, you can use any third-party PCIe Compression Accelerator cards.
