CDNs and Net Neutrality
By patching their networks together, many small and large network operators around the world have built a global virtual network: the Internet. It offers open and global access to any server and service in any connected network. The open and neutral character is what made the Internet the next big thing in humanity. So it is important to keep it open and neutral. And it is important to keep it running.
Iin the past few years, there has been discussion about Net Neutrality. Are ISPs allowed to block services? No? What about spam? Are ISPs allowed to shape traffic? No? Not even if a small number of subscribers can take their entire network down? Are ISP’s allowed to rent network resources to service providers so they can accelerate specific services?
In the USA, the Net Neutrality discussion is very polarized: either you are ‘freedom fighter’ who want laws to make sure that no single bit is discriminated or accelerated, or you are against government involvement and want the TelCos to be able to tune their network.
In Europe, we have a different view… Read more »
There is no European market
U.S. based CDN’s often tend to think that they can enter the European market by having an office in London, Paris or Amsterdam.
Although there is a European Union, without borders, with free economics and a single currency, there is no single market like there is in the U.S.A.
There are over 25 countries and even more languages in Europe. You will encounter cultural and language barriers. Opening an office in London also means a geographical barrier.
Why are telecom operators deploying CDNs?
Telecom operators have a four-way strategy to own an on-net CDN. On-net CDNs offer deeper network penetration with better QoS and larger capacity. The CDNs that we deploy support all popular delivery technologies for the web, mobile and IPTV. This means that the telecom operators can:
- optimize on-net traffic flow, reduce backbone and peering load
- host and deliver on-net web, mobile and IPTV services
- sell CDN resources to content owners
- Take back the distribution role in the value chain
External CDNs could only have addressed number 3 in this list. Read more »
Peer2Peer s*cks, here’s why
Peer2Peer (P2P) is sometimes proposed as an alternative for distributed content delivery. Some CDN’s are built upon P2P technology. P2P vendors, researchers and CDN’s claim that P2P lowers costs. It does. For the content owner. But it raises costs for the network owners. Significantly.
Basically the concept of P2P is that every client can redistribute content to other clients. As a content provider you don’t need to buy servers or traffic. Your audience distributes your content ‘for free’. Ingest the content into the network and let it flow. It is also hard to trace where content is hosted and ingested from. That is why P2P is so popular for (illegal) file sharing services.
Digital Logistics
2002. Since I already had a background in distributed delivery, I dived deeper into the internet infrastructure, to come up with a smart distributed solution for mass-scale content delivery.
It involved a simple number of technologies I already had developed in operational or rudimentary form. Parallelized delivery servers as core and edge servers. A smart asset and live relay replication mechanism. A smart geo load balancing application. Some log processing scripts.
Technical stuff. But why and how does this work? Let’s compare this with Logistics. Read more »
Video Working Group
2002. I had done a lot of research on broadband capacity, edge distribution and CDN management. I foresaw that the Internet would break under the increasing load of online video. I had experienced (eh caused) it myself one time.
The ISP’s would struggle to keep their business case positive. Content owners would be forced to outsource delivery to CDN’s. Who would only be able to distribute to ISP’s.
The iTuner
2005. Inspired by RSS and Podcasting, I began experimenting with video subscription services. Live and VOD streams via RSS. I called this VODcasting.
I was -and still am- convinced that internet video volumes are still small. The big bang is when consumers will consume high quality video streams in their homes. Sitting on their couch, eating chips, drinking cola and staring at their 52″ plasma’s or whatever, for hours.
There had been some initiatives towards internet stream based Set Top Boxes. Most really were crap. Utter total crap. If it wasn’t the hardware, it was the software. Even the Philips Streamium box sucked.
And if the boxes were OK, then they lacked a good interface, or they could only be used in a proprietary setting, with locked protocols, custom codecs and difficult middleware, exclusive content.
The Connected Home
2004. Ah, Fiber to the Home. The holy grail. According to many. Experts warned the government that if we did not invest in the Last Mile today, the Netherlands would become a third world country and internet services would never take off. So they asked the government to invest millions of tax payers money in new Last Miles.
I was a bit sceptical about their claims. Because I coincidentally had done some research about the bottlenecks of the Dutch Internet. And my conclusion was that the Last Mile could perfectly handle future growth, but that the true bottlenecks were at the ISP core backbones, the Internet Exchange and their interconnects (public and private peers).
The experts claimed that broadband services would require more than 20Mbps capacity per household. Maybe even 100Mbps in the future. But there was no research done to prove this claim.
