Jet-Stream Gold Sponsor Content Delivery Summit

Jet-Stream is Gold Sponsor for Content Delivery Summit, May 14 2012, New York

Scott Landman, Jet-Stream Vice President Americas will address the economics of deploying Content Delivery Networks for telecom operators and content publishers. 

Jet-Stream deployed over 30 CDNs for telecom operators and broadcasters across the globe. These CDNs aren't just operationally successful, but commercially as well, with up to 45% profit margins. With this unique experience, we know where to cut costs and we know which models do and don't work.

What are the major cost factors? Which factor is the most expensive: network, delivery servers, CDN management, workflow integration, deployment, support or operation? How can CDNs be optimized to optimize and offload the network? How can CDNs eliminate overhead equipment costs? What are the economic pitfalls of Internet CDNs and vendor CDNs? Why are Internet CDNs unable to lower their capex and opex? How expensive is building a CDN from scratch compared to buying off the shelves technology? How can operational and support costs be minimized? Which one is really cheaper from a TCO perspective: COTS or appliances?

Which factors are key for commercial succes? Why is it a bad idea to build a business case on traffic alone? Why have Internet CDNs been unable to turn their business into sustainable profitability? How to prevent becoming a commodity? Do you need both a retail and a wholesale strategy? Does CDN federation really bring new revenues? Is it enough to be reactive or do you need to proactively build a product strategy? How do best effort CDN technologies and locked in CDN technologies limit a serious business case?

BroadThinking 2012

BroadThinking is the event where the worlds of broadcast and broadband meet.

CEO Stef van der Ziel speaks about the future of IP video.
P2P failed to deliver. Internet CDNs fail to deliver. Broadcasters don't like transparent caching.
Premium content deserves premium CDNs, operated by telcos.

Stef van der Ziel is talking about QoS and SLAs, enabled by premium operator CDNs.

Best effort vs Premium CDNs

When CDNs emerged in the late nineties, their purpose was to deliver content as best as possible on a best effort network: the Internet. Even though global CDNs offer SLA's, these SLA's only cover their own pipes, servers and support.

Global CDNs dump their traffic on the Internet, via carriers or peering links, on internet excanges, into ISP networks. Their SLA's don't cover any capacity guarantee, delivery guarantee or quality guarantee. 

So it made a lot of sense for these global CDNs to use matching technologies: caching and DNS. Both technologies are best effort technologies because they do not offer guarantee or control. Which wasn't a requirement on the Internet.

Caching assumes that an edge cache can pull in an object from an origin. But what if the origin or the link to the origin is unavailable? Caching assumes that an edge cache can pull in an object in real time. But what if the origin or the link to the origin is slow? There are too many assumptions but there is no 100% guarantee that every individual viewer can get access to the requested object, there is no 100% guarantee that the file wasn't corrupted in the caching process, there is no 100% guarantee that the end user gets the object in realtime. Caching is a passive distribution technology without any guarantees. Best effort.

DNS assumes that an end user is in the same region as their DNS server. But what if the user is using another DNS server? The end user will connect to a remote server, with dramatic performance reduction and higher costs for the CDN. DNS assumes that other DNS servers respect their TTLs. But what if they don't? End users will connect to a dead or overloaded cache, dramatically degrading the uptime of the CDN. There are many more downsides to DNS. DNS is a passive request routing technology without any guarantees. Best effort.

Downsides of HTTP adaptive bit rate streaming

I wrote a number of articles about the shortcomings of HTTP Adaptive Bit Rate Streaming (HABS). 

Jet-Stream R&D identified another number of issues that cripple massive adoption of these technologies:
