Windows Vista and PNRP
Hi all,
as preparation for my master thesis I have to make an elaboration about PNRP and its applications but I just
found some information on wikipedia.org.
These information is to less technical and not very detailed so I decided to make a thread in a forum where
people should know what exactly PNRP is (definitions) and where it can be used.
Of course I also found some information on Microsofts Tecchannel but even that is not enought.
PNRP in version 2.0 (I think this is the Vista version) is very new and not very common in use so the search
for literature is not very fertile.
Maybe someone can help me with some whitepapers or elaborations or can hint me where I can find
such things.
Many thanks in advance,
Andreas
Hello Andreas,
We have a whitepaper for PNRP published here:
http://www.microsoft.com/technet/network/p2p/pnrp.mspx
It goes into more detail about how PNRP works, and hopefully it can answer some of your questions. If after reading the whitepaper you have any additional questions, we'd be happy to discuss them.
Thanks,
Vladimir
Hi you both,
I am just at the beginning of this elaboration about PNRP but I am still searching for some "mathematically" background,
so to say the complexity-calculation for e.g. adding new nodes to the network.
If I will not find anything I will post here once again.
Thanks in advance,
Andreas
Hello everybody,
at the moment something is not realy clear for me: Each node in an existing network has his own cache, the multi-level structered one, further
PNRP uses distributed hash tables but for what reason? The connection between DHT and muli-level-cache is not clear for me.
Could someone of you be so kind and try to explain?
Hi,
PNRP is not really a DHT, it is more like Distributed Routing Table (DRT). It proving the routing infrastructure based on the key. Multi-level cache is used to make routing decision more efficiently.
Please let me know if you need some more clarification.
Thanks,
Pritam
I have another question regarding the different levels of the multi level cache:
Once a level has reached its maximum numbers of entries a new level is created.
In which way the already existing entries are alloted to the new level? Can someone pls explain in detail?
According to image 4 on http://www.microsoft.com/technet/network/p2p/pnrp.mspx each lvl of the cache can contain 10 entries. Once a level has reached this maximum a new level is created, more or less below the level that has reached the maximum number of entries.
My question: Are any entries taken from the full cache level with 10 entries to the newly generated level and if so, which entries are moving to the newly generated level?
