When operating a large global network that supports thousands of web applications and streaming media services, dealing with distributed denial-of-service (DDoS) attacks is part of our day-to-day operations. Having a resilient and intelligent DDoS mitigation platform is essential to the operation of our network and to the web services that depend on it.

Today xTCP joins vFlow (sflow, netflow, ipfix collector) in our suite of open-source network monitoring tools.

When operating large, globally distributed networks, hardware failures, provider outages, and other changes in behavior are regular occurrences. Therefore, systems that can raise alarms at the first signs of trouble can alert human operators or automated systems and enable faster corrective action. To this end, we developed ShakeAlert, an alerting system built on publicly available, external data to alert to sudden Internet changes.

The following is an example of integrating Kubernetes with Edgio Delivery CDN service for experienced Kubernetes practitioners. It assumes a level of knowledge in Kubernetes and knowledge of standard internet protocols such as TCP, DNS, and HTTP/HTTPS. The final objective is to demonstrate a way to make Edgio Delivery CDN service appear as standard ingress.

Edgecast, now Edgio, Rules Engine allows enterprises to fine-tune configurations with flexibility and ease.

Given that congestion control tunings using BBR for one customer can adversely affect another customer’s performance, and a blanket enablement might result in degradation of performance in some scenarios, we implemented a mechanism to detect cases where BBR provides improved performance and can dynamically enable it for all CDN customers.

Better understand session drift and learn about solutions to help you deliver a great user experience while optimizing monetization with server-side ad insertion.

Read our evaluation of an adaptive CDN request load balancing system and usage of dynamic hot filing. See what the results are.

Content delivery networks have enabled edge compute use cases for many years, offering massive network capacity and just milliseconds of latency to virtually every connected device and internet user on the planet.

Learning Ally was able to absorb a wave of new subscribers and expand its offerings in response to COVID-19.

Digital rights management (DRM) is an industry standard that gives content owners options for protecting premium content. An effective DRM solution must work with the vast majority of playback devices, integrate easily into the workflow, and appear transparent to users. 

Reducing latency has become a focus for streaming service providers. For sports tied to split-second gaming bets, such as horse racing, delayed streams put remote participants at a disadvantage to those at the venue.

In this post, we'll review examples of recent performance optimizations we made for a large North American vMVPD streaming service.

To keep up with the growing volume of media content, Edgio has invested in expanding our global cache footprint.

As streaming services battle for a limited number of viewers and shrinking attention spans, live events, which are a proven driver of audience engagement, have become an important factor in a publisher’s content strategy. 

Bottleneck Bandwidth and Round-trip propagation time (BBR) is a TCP congestion control algorithm that has gained significant market attention due to its ability to deliver higher throughput as reported by many content providers. In this article, we evaluate BBR (version 1) in the context of Verizon Media’s, now Edgio's, content delivery network (CDN) workloads, which delivers significant volumes (multiple Tbps) of software updates and streaming video, and quantify the benefits and impact on the traffic.

As an increasing number of major broadcasters and advertisers adopt server-side ad insertion, Edgio is keeping pace with demand by developing an ad proxy service focused on supporting these activities.

In the early days of video streaming, viewers were willing to endure a frustrating playback experience to gain access to exclusive content. As the number of content providers sharing their content among multiple distributors has grown, Quality of Experience (QoE) has become vital to viewer retention.

Personalized viewing experiences at a 1:1 level are transforming the TV experience. Instead of one-size-fits-all, viewers get targeted and highly relevant advertising, tailored content, recommendations for new programs, and precise DRM/blackout management, all based on your viewers’ device type, location, history, demographics, and other data.

Maintaining quality at scale involves optimizing performance across every part of the Edgio Media Platform tech stack: from its lower layers, at the CPU and NIC, all the way up to the OS and the applications. Ultimately, our goal is always the same: great performance.

In this technology blog, we look at how we’ve built our platform to enable a publisher to optimize the first step in the streaming video workflow, look at some of the challenges involved, and explain how we encode the live stream to enable high performance, low latency, ad-supported live streaming.
