- e28eta 10y agoI was using "caching" to talk about the Open Connect Appliances and Netflix's proprietary CDN. It's probably the wrong word to use, given the differences in how the system works. It doesn't sound like a customer watching a video stream causes that video to be copied to an OCA. The "Proactive Caching" section says they "want to make all of the OCA capacity available for content serving" and are trying to avoid read/write contention during peak hours. It sounds like the system's working pretty well, the previous blog post says: "Globally, close to 90% of our traffic is delivered via direct connections between Open Connect and the residential Internet Service Providers (ISPs) our members use to access the internet."
- jsprogrammer 10y agoYeah, in my reading it doesn't seem like they cache on request. I don't think they said that they only cache some content though. They likely cache everything, but do so before making that content available to viewers.
