Transparent Caching and CDN: What’s Driving the Converged Offering?

Traditionally, managed subscription services have been delivered via CDNs at the Internet edge, while unmanaged over-the-top content is delivered from transparent caches at the access network edge. Recent industry developments suggest that these two formerly separate approaches will become more coordinated, creating a unified delivery infrastructure that will bring both CDN-managed and OTT content to the network edge - improving end user quality and network economics.

At the Content Delivery Summit, taking place Monday, May 14th in NYC, this session will review the trends that are driving this transformation, and explain how these different delivery methods are converging. It will explore the technical and business benefits and challenges for content providers, network operators and consumers. Confirmed speakers include:

• Moderator: Mark Taylor, VP, Media and IP Services, Level 3

Learn How To Marry CDNs with Front-End Optimization for Maximum Acceleration

Many content owners are already using a content delivery network (CDN) to cache content closer to their visitors, but CDNs don't reduce the number of requests required to render each page, and they have no impact on browser efficiency. At the Content Delivery Summit, taking place Monday, May 14th in NYC, learn how Front-end optimization (FEO) picks up where CDNs leave off, transforming the content itself so that it renders as quickly as possible in the browser.

Joshua Bixby, President of Strangeloop Networks will enable attendees to see real-world examples of how leading e-commerce sites have combined CDN and FEO forces to reach new levels of performance for content-rich pages. Get real numbers on how quickly content-rich sites loaded pre-acceleration, then with just a CDN, then with a combined CDN/FEO solution.

Comcast Prioritizing Their Video Content Over Competitors Traffic, Here's The Proof

[Updated 5/22: In a blog post, Comcast says they are not prioritizing traffic, but Level 3 says they are.]

Last year, when Comcast acquired NBC Universal they had to agree to terms as set forth by the Department Of Justice and the FCC regarding how they would treat competitive content delivered over their network. One of the points in that document says that, "Comcast shall not prioritize Defendants’ Video Programming or other content over other Persons’ Video Programming or other content." While Comcast agreed to these terms and said they would not prioritize their video traffic over someone like Netflix, that's exactly what they are doing.

Based on details I have gotten from those who have looked at how packets are marked on their home broadband connections provided by Comcast, packets are in fact being marked with Quality of Service tags. Services from MLB, Hulu and Netflix are marked with CS1 tags and Xfinity is marked as CS5. In tests, the Xfinity traffic originates from servers inside Comcast's network and the other traffic originates on Level 3 and Akamai servers outside Comcast's network. All of these QoS tags are put on by Comcast.

According to the IETF the QoS tags have the following definitions;

• CS1: This service is the low class of service and effectively gets any bandwidth left after every other service has transmitted over the link. "The fundamental service offered to the Low-Priority Data service class is best-effort service with zero bandwidth assurance". This class gets any of the scraps left over after all other classes have had their packets forwarded.

• CS5: This service is considered a high class of service that gets processed such that it is ensured to get forwarded: "The Signaling service class SHOULD use the Class Selector (CS) PHB, defined in [RFC2474]. This service class SHOULD be configured to provide a minimum bandwidth assurance for CS5 marked packets to ensure they get forwarded."

All Internet traffic from at least the cable modem termination system to the home cable modem shares exactly the same path. There is no "private IP network" between those points. While I don't know how the Comcast servers that deliver the Xfinity traffic connect to the cable modem termination system, and while that part could be part of a private network, I think that's unlikely.

The part of the network from the cable modem termination system to the homes is usually the most congested and that equipment in the cable modem termination system is capable of acting on those QoS tags and so could treat the traffic differently. What I don't know is if they are treating the two tags differently, but the tags are there. If they aren't making use of them why are they adding them?

And if they are using them I think you could then make a reasonable assertion that the spirit, if not the letter, of the DoJ statement is being broken by Comcast. I've put in a request to Comcast to see if they want to address this and will update the post once I hear back.

Updated: If you'd like to do this testing for yourself, here is a PDF that shows you how to do it.

XO Communications Launches CDN Services Using Limelight's Managed CDN Platform

Earlier in the week, XO Communications (XOHO.OB) announced the launch of Concentric Cloud Solutions, a division of XO Communications that will be focused on providing cloud services for computing, content acceleration and voice. Part of the solution will entail CDN services for content caching, application acceleration and video streaming. XO has chosen Limelight Networks (LLNW) managed CDN platform for their underlying technology and XO is already selling their new solution in the market.

XO has more than 60,000 small and medium sized customers spread out across North America (and host more than 23,000 websites), so the company has quite a big built-in customer list they can up-sell these new cloud services to. Based on outreach XO has done to their customer base, they think that they can immediately upsell new services like DSA and video streaming to at least 10% of their clients.

XO also said that customers can easily manage and maintain their services through the Concentric.com website, as a self service model, and can benefit from the ability to purchase services in pay-as-you-go or monthly payment plans. XO's plan it to take the services Limelight offers via their platform and package them into bundles for the small, mid-size and enterprise markets as well as for specific verticals.

Over time, XO's goal is to move from a managed CDN model with Limelight to one where they simply license Limelight's technology and then deploy and manage all of their own hardware. That's a very similar path we have seen for others who have started with a managed CDN (MCDN) offering and moved to a licensed CDN (LCDN) model over time, but it typically takes a few years to make that transition.

You can hear more about these kinds of manged and licensed CDN deployments at the Content Delivery Summit on May 14th in NYC.
