Live video just got more live: Introducing Concurrent Streaming Acceleration

Live video just got more live: Introducing Concurrent Streaming Acceleration

Today we’re excited to introduce Concurrent Streaming Acceleration, a new technique for reducing the end-to-end latency of live video on the web when using Stream Delivery.

Let’s dig into live-streaming latency, why it’s important, and what folks have done to improve it.

How “live” is “live” video?

Live streaming makes up an increasing share of video on the web. Whether it’s a TV broadcast, a live game show, or an online classroom, users expect video to arrive quickly and smoothly. And the promise of “live” is that the user is seeing events as they happen. But just how close to “real-time” is “live” Internet video?

Delivering live video on the Internet is still hard and adds lots of latency:

  1. The content source records video and sends it to an encoding server;
  2. The origin server transforms this video into a format like DASH, HLS or CMAF that can be delivered to millions of devices efficiently;
  3. A CDN is typically used to deliver encoded video across the globe
  4. Client players decode the video and render it on the screen

And all of this is under a time constraint — the whole process need to happen in a few seconds, or video experiences Continue reading

Will 5G be the first carbon-neutral network?

If wireless networks transfer 1,000 times more data, does that mean they will use 1,000 times more energy? It probably would with the old 4G LTE wireless technologies— LTE doesn’t have much of a sleep-standby. But with 5G, we might have a more energy-efficient option.More customers want Earth-friendly options, and engineers are now working on how to achieve it — meaning 5G might introduce the first zero-carbon networks. It’s not all certain, though.[ Related: What is 5G wireless? And how it will change networking as we know it ] “When the 4G technology for wireless communication was developed, not many people thought about how much energy is consumed in transmitting bits of information,” says Emil Björnson, associate professor of communication systems at Linkoping University, in an article on the school’s website.To read this article in full, please click here

Stop the Low-Level Configuration Manipulation

This blog post was initially sent to subscribers of my SDN and Network Automation mailing list. Subscribe here.

Imagine a small bank deciding in their infinite wisdom (in reality: because their CIO attended a conference organized by a database vendor) to implement their banking software by teaching bank tellers how to type SQL transactions by hand.

For example, to transfer money from one account to another account, a bank teller could simply type:
