On-Net Caching Checklist

Key considerations for identifying your business needs


For service providers, video streaming and online gaming are key drivers of revenue and growth. But they are bandwidth intensive, putting pressure on cost and infrastructure. To help handle the load, reduce backhaul cost, improve performance and even open potential revenue opportunities, installing Content Delivery Network technology (CDN) on-net is an option. The following provides guidance for identifying the key considerations and questions to ask.

1. Is Content Delivery creating high costs on your network?

Retrieving content from remote, off-net origin or cache can become a significant cost line item in areas where backhaul is expensive. As demand grows, this cost of content retrieval can spiral out of control.

How much are you spending to retrieve streaming video and other content from off-net?
  • High cost
  • Considerable cost
  • Free


If you’re spending considerable sums retrieving content from remote sources, on-net caching can dramatically reduce backhaul cost for Limelight traffic. Retrieve it once, then serve future requests out of cache on your own network.

2. Are you motivated to monetize your network?

Many service providers are tired of just watching money flow through the network. Popular global services like streaming video providers can have a huge impact on bandwidth and cost with little or no explicit contribution to revenue. Unfortunately, these dynamics can sometimes be one-sided — you deliver high-value payloads without monetizing the value you provide.

What is your position on revenue opportunities?
  • New revenue opportunities are a high priority for the organization
  • Other issues like cost and quality of service are more important
  • Revenue generation isn’t a priority


If new revenue is a goal, you’ll be excited to hear about revenue opportunities that can boost your bottom line. Unlike many other caching programs, Limelight Service Provider Solutions offers potential to capture revenue from traffic that content providers are delivering through your network. The more traffic you deliver, the more revenue you’ll receive. Flexible business models, including revenue sharing opportunities, make it easy to craft a solution that benefits your business.

3. Is access to content a concern?

You can’t deliver streaming video and other content if you can’t access it. Especially during peak hours, network operators can suffer degraded user experience and failed sessions when content is inaccessible.

How does your content access stack up?
  • Accessing content for delivery can be a frequent problem
  • Accessing content for delivery can be a problem occasionally
  • We don’t have concerns about access to content


You can take control of content access with on-net caching of popular videos and other assets or faster and more reliable egress into the delivery network.

4. What are your users content performance expectations?

User expectations can vary by region, but one thing is certain. Expectations for quality and reliability are increasing, not decreasing. In developed regions, users have been consuming streaming video for years and now expect higher resolution and faster start time. In developing regions users may initially tolerate problems, however the honeymoon phase ends rapidly especially where there’s competition.

What are your users’ expectations for streaming video?
  • High-quality, highly reliable HD and 4K
  • Good quality and reliability at moderate bandwidth
  • Imperfect quality and reliability is acceptable — for now


Satisfying users is the key to reducing churn and winning new subscribers. Wherever today’s expectations are, they’ll be higher in the future. Opportunities for growth depend on staying ahead of rising expectations. Caching content on-net can solidify business today and future-proof business for growth to come.

5. Do you provide your own video or other content?

If you are a content provider as well as a delivery provider, the stakes are higher — especially if the content you own or license provides revenue or helps you attract and retain subscribers.

Do you provide your own content?
  • We own or license content, and focus on delivering that content
  • We own or license content, and deliver a mix of our content and other providers’ content
  • We deliver other providers’ content


For your own content, you need not just the ability to manage delivery but to manage the assets themselves. On-net caching with managed CDN services may be ideal for your situation.

6. What are your market dynamics?

Your needs and drivers are partly a function of the market you operate in.

What are your market dynamics?
  • The market is relatively mature and stable
  • The market is established and growing
  • The market is developing and poised for significant future growth


The more mature and stable a market, the more important customer satisfaction to attract and retain subscribers. More dynamic, growing markets provide windows of opportunity to seize shares if you’re prepared to meet growing demand.

7. Do you connect with other providers in your region?

Connections with other operators, especially high-bandwidth connections such as those found in internet exchange points, can spell opportunity.

What is your range of delivery and partnership profiles?
  • We only serve users on our own network
  • Peering with other providers has technical value but not monetization value
  • Monetizing content to other regional networks could be valuable


On-net caching may provide opportunities to serve content to other network operators. With access to other operators through internet exchange points, you can leverage content cached on your network. The flexible business models offered within Limelight’s Service Provider Solutions afford the ability to further monetize your network and its assets.
