Correct. All content is mastered and uploaded to the CDNs. BTW, the BBC has virtually nothing to do with actually storing the stuff - they use the same CDN providers as all the others - Akamai, Limelight and Level 3.
The Internet as it is currently built is hopeless at end-to-end streaming - that is why your content typically comes froma CDN positioned somewhere very close to you (usually within one or two hops). The CDN providers position the content to their caches (usually located at a Aggregation point but these days in some markets can go as close a street cabinet or cell-site) using their own highly-optimised back-end networks. The only different is live-linear - still served by the CDN providers and not actually by the BBC. This should go IP multicast but, due to the general stupidity of the Internet and the fact that it has "happened" rather than been "designed," even the forward-looking SPs are moving away from IP multicast for live-linear (BT Vision is moving to all unicast some time soon GRRR).

Pretty sure iPlayer isn't a Redux client. Or at least, if it is it also gets lots of content from elsewhere. For example, stuff that isn't broadcast in London: https://www.bbc.co.uk/iplayer/episode/b0bwr3wl/ and stuff that was never broadcast: https://www.bbc.co.uk/iplayer/episode/p04tspjl/ -- David Cantrell | Minister for Arbitrary Justice _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer _______________________________________________ get_iplayer mailing list get_iplayer@lists.infradead.org http://lists.infradead.org/mailman/listinfo/get_iplayer
