By automating capacity planning for IP networks, we can achieve cost reduction, enhanced accuracy, and better scalability. This process requires us to collect data, build predictive models, define optimization objectives, design decision algorithms, and carry out consistent monitoring and adjustment. However, the initial investment is large and the result will still require human oversight.

Live sports have moved to the internet and are now streaming instead of being broadcast. Traditional streaming protocols have a built-in delay that challenges the experience of a live game. Amazon Prime has found a solution by combining a new protocol with a very distributed CDN.

This guide explores the benefits of embedded caching for ISPs and discusses deployment optimization strategies and future trends in CDN technology. Embedded CDNs help reduce network congestion, save costs, and improve user experiences. ISPs must carefully plan their deployment strategies by considering how each of the CDNs distributes content and directs end-users to the caches. They need to know both the CDNs and their network architecture in detail to build a successful solution.

Content delivery networks are an important part of the internet, as they ensure a short path between content and the consumers. The idea of placing CDN caches inside ISPs networks was created early in the days of CDNs. The number of CDNs with this offering is growing and ISPs all over the world take advantage of the idea. This post explains how this works and what to look out for to do it right.

Resiliency is a network’s ability to recover and maintain its performance despite failures or disruptions, and redundancy is the duplication of critical components or functions to ensure continuous operation in case of failure. But how do the two concepts interact? Is doubling up on capacity and devices always needed to keep the service levels up?

In this post, Nina Bargisen explores how peering coordinators can use combined NetFlow and BGP analysis tools to work around different capacity upgrades when money or delivery times pose a challenge.

A critical milestone in any peering relationship is the business review; and when it comes to business reviews, it’s all about preparation. Learn how Kentik can help.

In part four of our series, you’ll learn how to find the right transit provider for your peering needs.

In part three of our series, you’ll see how to improve CDN and peering connectivity. Learn about peering policies and see how to use data to support your peering decisions.

In part two of our peering series, we look at performance. Read on to see how to understand the services used by your customers.

In this blog series, we dive deep into the peering coordinator workflow and show how the right tools can help you be successful in your role. In part 1, we discuss the economics of connectivity.
