RESEARCH 》 CDN Content Delivery Networks - Types

Internet based CDN: Internet based CDN the CDN Services provider will place 100s of CDN caching nodes across the internet (usually in ISPs), and serving the end-user content requests directly from these CDN nodes instead from the main origin web-server(s) of the website.

Private CDN: There can be multiple types of CDN infrastructure, such as CDN service provider Networks/Infrastructure (discussed mostly so far) where end-users or customers rent their infrastructure via their paid services. And in another case a company can build their own company’s proprietary private CDN infrastructure where a company builds it and uses for their own services (for example infrastructure of Google), then a hybrid of both where there can be an interconnected CDN service provider’s network and proprietary CDN.

Sometimes these private CDN Networks can be built from scratch from their own built from scratch tools and infrastructure, and sometimes they can use other third-party tools and platform to build the same. In either case, simply put private CDN is the private built CDN built for the purpose of its own firm. It is not a CDN service provider infrastructure.

The main advantages of private CDN is the data security. Since it is 100% private infrastructure, the data and all the resources are available in the company’s owned machines. Hence sometimes depending on the requirement where there is huge traffic and also a need to highly secure this data, sometimes it is necessary to build an organization’s own private CDN either with technology built by them, or either buying CDN building tools from third party CDN Software/tool vendors. Hence sometimes any CDN Service provider, can also build these tools/software/hardware and so on, and can sell to their customers to enable them to build their own 100% private CDN infrastructure.

Peer-to-Peer (P2P) CDN: We know Peer-to-peer (P2P) technology is widely used in bulk file downloads via torrents. Unfortunately most people often relate P2P with respect to illegal data/file sharing. These days more and more large software downloads are available via P2P technology. This even includes several official ISO Linux Distribution Download formats.

So a CDN based on peer-to-peer (P2P) technology can be built to achieve this goal. Services like Napster, and the infamous Pirate Bay and so on, made headlines after being sued by major recording industry and movie industry corporations that claimed the file sharing services violated their copyright. Nevertheless, the technology itself is legal and very useful for practical file distribution and in this case as a core CDN objective (such as load-sharing, content distribution, redundancy, and so on). So even large companies like AT&T to non-profit university libraries rely on P2P content distribution.

P2P itself is not one type of technology but rather refers to several types of protocols, including Gnutella, BitTorrent, and and FastTrack protocols. CDN Networks can use P2P to distribute a website’s content without needing to cache the content on other dedicated servers (as in the case of traditional Internet based CDN scenario). Instead, the users accessing the site share in the distribution of the content, without any adverse effects on their experiences.

Because a P2P CDN requires less power and hardware from the CDN service itself, many P2P CDNs offer their services for free. Websites that want to participate usually need to append the service’s URL to their content URLs or add certain code to their websites.

How to check a website using CDN? If you are looking ways to find a website is using a CDN, you can follow this guide HERE. This way you can know if the website is using any CDN service and its corresponding CDN vendor(s) providing the subscription(s) services.

Replacing in Lab Intel Core i7 5820K Desktop PC with Intel Celeron 1037U Mini-PC ↗
Saturday' 13-Mar-2021
As a research experiment I replaced my Intel Core i7 5820K desktop PC with my Intel Celeron 1037U Mini-PC as my everyday desktop system. This is an attempt to reduce my overall monthly power consumption. As well an attempt to do feasibility tests and research to know how far Mini PC will dominate the market in future and to study the real potential of Mini PCs.

TOFFEE (and TOFFEE-DataCenter) optimized Mobile Wireless Backhaul Networks ↗
Saturday' 13-Mar-2021
TOFFEE can be used to optimize expensive Wireless backhaul network infrastructure. TOFFEE can be deployed over existing slow or often outdated old backhaul networks too. This will leverage mobile ISPs and network service providers to reduce their bulk IT CapEx and OpEx Costs.

Benchmark Raspberry Pi and other embedded SoC with TrueBench ↗

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. With TrueBench Raspberry Pi 3, Raspberry Pi 2B and Raspberry Pi 2 are benchmarked and you can do a comparative analysis with standard mainstream x86 devices.

TOFFEE (and TOFFEE-DataCenter) optimized Satellite (inflight/marine/defense) ISP Networks ↗
Saturday' 13-Mar-2021
TOFFEE Optimized Satellite ISP Network: TOFFEE/TOFFEE-DataCenter can be used to optimize Satellite Networks (Satellite based Internet Networks, VoIP, Data, private leased-links) as shown. Ground station transponders can be connected via array of TOFFEE Devices and in the remote CPE can have dedicated or inbuilt TOFFEE with which you can establish a WAN Optimized Satellite Network Tunnel as shown.

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.

Introducing TOFFEE-Butterscotch - Save and Optimize your Internet/WAN bandwidth ↗
Saturday' 13-Mar-2021
TOFFEE-Butterscotch yet another variant of TOFFEE can be used to save and optimize your Home/SOHO Internet/WAN bandwidth. Unlike TOFFEE (and TOFFEE-DataCenter) TOFFEE-Butterscotch is a non peer-to-peer (and asymmetric) network optimization solution. This makes TOFFEE-Butterscotch an ideal tool for all Home and SOHO users.

TOFFEE-Mocha WAN Emulation software development - Update: 18-June-2016 ↗
Saturday' 13-Mar-2021
In the previous update (17-Jun-2016) I discussed about the upcoming new Random Packet drop feature along with other completed features. Now I completed the entire TOFFEE-Mocha Random packet drop feature. I completed all the kernel components and the UI support of the same. And to make GUI settings more organized I split the earlier Basic-Settings page into two separate pages namely: Packet Drop and Packet Delay. So this way it is simple to understand settings according to their functionality.

Here is my power-consumption measurements of various devices deployed within my home lab. I measured via my kill-a-watt sort of power-meter which is fairly reliable and accurate. I checked its accuracy with various standard load such as Philips LED laps and other constant power-consuming devices to make sure that the power-meter is precise.

Building my own CDN - choosing a web-hosting to deploy my CDN - Update: 28-July-2016 ↗
Saturday' 13-Mar-2021
The TOFFEE Project website is hosted on Inmotion Hosting. And so I am looking for alternate hosting provider to build my first CDN node. My plan is to make multiple sub-domains of my website such as cdn1.the-toffee-project.org, cdn2.the-toffee-project.org and point each of this corresponding subdomain(s) to various alternative web hosting servers geographically spread across the world. Sometimes choosing the same vendor for multiple CDN nodes may result multiple servers existing in the data-center. And this becomes an issue if there is some catastrophic network disaster.

A study on WAN Optimization Techniques ↗
Saturday' 13-Mar-2021
There are various techniques with which one can optimize their WAN Network Data. Any long distance communication can be considered as WAN Network. A decade ago any network connecting two countries, considered as a WAN network, and a network within a city as MAN and soon. But these days in general any long distance communication is considered as WAN Network. Such as your Mobile communication networks, Satellite networks, Space Networks (Deep space networks), Trans-Atlantic cable networks, etc.
