[edit] Network Overlay or Overlay Network?
I've heard the latter form much more often. I would recommend moving to that form and redirecting from Network Overlay to there. Justification:
- On Google: 6,810 hits for "Network Overlay", 81,400 hits for "Overlay Network". Similar results in Google Scholar.
- NSDI, one of the major networking conferences, uses "Overlay Networks" as the subject matter of one of their tech sessions [1].
Any disagreement? -- Nethgirb 07:28, 29 July 2005 (UTC)
[edit] MLdonkey
I think that "MLdonkey" should be removed from the "Network overlay" page, since it's the name of a P2P client, not of a Network overlay (it's listed in an external page because it implements some of the Overnet protocol, that's based on the Kademlia algorithm, that is already listed as network overlay).
To be even more precise, I think there was a project to create a network overlay specific to MLdonkey clients, but as far as I know it never went past the project state, and some dead code in the sources (src/networks/donkey/donkeySupernode.ml,...) (only the main programmer of MLdonkey, could tell for sure: b8_bavard)
[edit] Dialup
The bit about dialup, in the intro, being an overlay on the telephone network seems a bit out of place. It confused me enough to have to reread the intro. If i'm not mistaken, I understand that any physical transmission medium can be overlayed with a communication network, so would it be better to state that and use dialup as example? Or is that example not about the physical telephone network but about the protocols used to implement the telephone network and dialup connection sequences riding on top of those protocols? -Isha —Preceding unsigned comment added by 64.105.154.140 (talk) 23:32, 23 January 2008 (UTC)
"Dial-up Internet is an overlay upon the telephone network."
Really? I'm confused by this too. After the initial connection to the ISP, dial-up is using the exact same Internet as everyone else. This seems more to describe the hardware medium involved in a network, rather than the logical concept of a network on top of another. --70.142.60.136 (talk) 00:26, 18 May 2008 (UTC)
- Let me try to explain what the author of that sentence meant. The answer is Isha's second guess: The telephone wires provide basic physical transmission medium; on top of that is the telephone network, which gives meaning to concepts like phone numbers; and on top of that is dial-up Internet, which gives meaning to concepts like IP addresses—hence, it is a network on top of a network, i.e., an overlay network. Dial-up Internet does not really use the physical medium directly; for example, to reach your ISP, you (or, the "you" of 15 years ago...) dial a phone number which is something that has meaning only to the telephone network.
- So the example is sound, though perhaps esoteric and poorly explained. It's also not the most compelling example, since only a very small part of the Internet as a whole is overlayed on the telephone network. --Nethgirb (talk) 01:07, 18 May 2008 (UTC)
[edit] networking
how can i make a networking in my building i have ten computer in our building i want to use networking on this by using one line dsl howcan i make the networking. —Preceding unsigned comment added by 77.30.120.105 (talk) 08:46, 11 February 2009 (UTC)
- Simply connect them all via ethernet cables to a switch and to the same switch you also connect your router/modem that provides the internet service... BTW, remember, wikipedia is NOT a help forum, there are much better places on the internet to post questions like this. Use Google. Old Death (talk) 19:50, 12 February 2009 (UTC)
[edit] logical address and IP address
"For example, distributed hash tables can be used to route messages to a node having specific logical address, whose IP address is not known in advance."
The DHT is a good example of an overlay network, but this statement gives the impression that there is a distinction between a logical address and an IP address (an IP address is a logical address). Baxevanis (talk) 14:31, 8 May 2009 (UTC)
