  • Caching Best Practices: From Origin to Personal Storage

Tuesday, December 14, 2021 at 10:00am (PT)

Caching is arguably the most fundamental component of the streaming workflow. Without caching, it would be impossible to scale a streaming service to serve hundreds, thousands, or even millions of simultaneous users. So how can we make caching better? What can we do to not only optimize caching performance, but improve its placement in the streaming architecture? In this webinar, we’ll address those questions and more, even discussing how caching might be placed in home networks or on consumer devices, as part of an Open Caching network, to provide better streaming performance through pre-positioning content. Panelists will be announced shortly. This webinar will be moderated by Jason Thibeault, Executive Director of the Streaming Video Alliance.

Topics Covered

  1. Let’s begin by talking about cache placement. Where are the optimal places to cache content? What are the tradeoffs for putting storage closer to the end user, even on the device itself?
  2. How does segment size affect cache efficiency and how can you optimize a cache to deal better with different segment sizes?
  3. What is the optimal balance between disk and memory storage for cache efficiency? -Dan
  4. Of course, caches rely on physical storage (such as disks or memory) but is it possible to virtualize the storage containers for better distribution of caches (such as in an edge compute environment)? What would be the benefits or drawbacks?
  5. Is there an ideal caching architecture such as caching groups, parent-caching layers, etc.? Does it depend on the use case (i.e., real-time live, ultra-low latency live, on-demand, etc.)?
  6. What is the impact of peer-to-peer caching (i.e., seeding) on overall cache efficiency? Is it use-case dependent? Is performance improvement related to segment size?
  7. How does a multi-network delivery architecture impact cache efficiency and management?
  8. How can ML and AI play a role in improving cache performance? Is there a way to automate delivery decisions based on how well a cache is serving content?
  9. What are the ways open caching can improve cache performance and management?
  10. Are there any new technologies or caching approaches we may see in the near future?
