raphael: 3th protocol: file implementation
09:57:08 [Gui]
09:57:24 [davy]
09:57:49 [Yves]
file always get the full result, so identifying fragment forces seeking
09:57:59 [rtroncy]

09:58:15 [jackjansen]

TOPIC: Issues
10:05:48 [davy]
raphael: caching discussion
10:05:58 [davy]
... time ranges is really hard
10:07:16 [rtroncy]
Jack: i think time is complex and cache should not necessary try to understand time ... thus only cache bytes range
10:07:39 [rtroncy]
Davy: I do not say exactly the contrary, but i'm arguing about implementation
10:08:19 [rtroncy]
Jack: caching time ranges requires cache server to do recombination ... so have knowledge about the various media container foramts
10:08:25 [rtroncy]
10:08:50 [davy]
yves: implementation hard or not, if we no it can be done, than there is no problem
10:09:12 [davy]
Jack: caching based on byte offsets will work on 99% of the cases
10:09:19 [rtroncy]
Yves: when the implementation is done ... it is done! We know it can be done ... implementation difficulty should not influence the design
10:10:51 [davy]
jack: it would work with time ranges, but I see no advantages
10:11:14 [davy]
Yves: with time ranges, you can directly request the fragment
10:11:22 [jackjansen]
zakim, mute me
10:11:22 [Zakim]
jackjansen should now be muted
10:11:49 [jackjansen]
zakim, unmute me
10:11:49 [Zakim]
jackjansen should no longer be muted
10:12:07 [davy]
jack: I fully agree
10:12:32 [davy]
... I think we should leave this issue open
