These unused connexions would likely be from faster mirrors. + +The advantage of an application like aria2c, is that it detects +automatically the speed of whatever the connexions are available from +the urls (mirrors) specified, and chooses the fastest connexions. +Thus downloading at an optimal speed for the user. +At the same time, it makes the best use of the resources available, +since the slowest connexions won't be used. Thus relieving slower mirrors. +(Considering direct downloads, not options like P2P.) +Of course each user will have their own set of fastest connexions, +depending on their location. A user in Australia would have different +connexions from someone in France, or here in Canada. +So in my view, the approach of aria2c is a win/win for both users and +mirrors. + +With aria2c, 3 mirrors which support a total of 5 connexions gives me +optimal speed. (The limit being the speed of my computer.) + +><i> But then I'm not sure there is so much more value than using a P2P protocol. +</I> +P2P is great if one has (essentially) unlimited bandwidth, and many +others are downloading at more or less the same time, and accessible to +the Internet when you are downloading. +And it does relieve bandwidth from the mirrors. + +But it's not as good for bandwidth limited users (which included many of +us), or those downloading at a time when not many corresponding P2P +downloaders are available. +(I knew someone who had a surprise 100$ plus surcharge due to P2P +uploading, before understanding the bandwidth usage factor.) + +An aria2c type solution doesn't require any cooperation from mirrors. +Although resource-limited mirrors should protect themselves from this +approach, to remain readily accessible. +I'm not sure what is required (from Mageia) for P2P, but it could be +worth considering. + +another 2 cents :) + +><i> Romain +</I> +-- +André +</PRE> + + + +<!--endarticle--> + <HR> + <P><UL> + <!--threads--> + <LI>Previous message: <A HREF="002076.html">[Mageia-dev] Proposal for Mageia: implement bitorrent protocol to allow updates download +</A></li> + <LI>Next message: <A HREF="002083.html">[Mageia-dev] Proposal for Mageia: implement bitorrent protocol to allow updates download +</A></li> + <LI> <B>Messages sorted by:</B> + <a href="date.html#2080">[ date ]</a> + <a href="thread.html#2080">[ thread ]</a> + <a href="subject.html#2080">[ subject ]</a> + <a href="author.html#2080">[ author ]</a> + </LI> + </UL> + +<hr> +<a href="https://www.mageia.org/mailman/listinfo/mageia-dev">More information about the Mageia-dev +mailing list</a><br> +</body></html> |
