How do I know at some point the size of the server emule
Now I do it again in the P2P, KAD network research papers ，would like to know at some point the whole server emule Size, I have heard that this feature itself emule, I hope you tell me how to use, very grateful.

you mean what ? how many users connect to it , how many files shared to it ......................

And I thought us girls were confusing..! eMule is more than a collection of it´s component parts.. (I mean electrical. it has to be, or it would´t be P2P..!!)

Try to rephrase your question or maybe take a look at other laguages forums here.

SORRY.Now I try to be accurate.
The question is
How to estimate the number of clients on a certain time in the emule network?

[fox88]

If you need the numbers - just look at the status bar of eMule (bottom of it's window).
For ED2K each server reports number of connections, so in theory just make a sum (but you cannot fully trust those numbers).
For KAD the number of users can be only estimated.

Thanks.
But I want to know the algorithm to estimate the number of clients on a certain time in the emule network.
Is it called "flooding"?

Excuse me, I have a question would you to help .
This is a part of the source code of emule .
It is the algorithm to estimate the number of clients on a certain time in the emule network.

//This is used when we find a leaf and want to know what this sample looks like.
//We fall back two levels and take a sample to try to minimize any areas of the
//tree that will give very bad results.
uint32 CRoutingZone::EstimateCount()
{
if( !IsLeaf() )
return 0;
if( m_uLevel < KBASE )
return (UINT)(pow(2.0F, (int)m_uLevel)*K);
CRoutingZone* pCurZone = m_pSuperZone->m_pSuperZone->m_pSuperZone;
// Find out how full this part of the tree is.
float fModify = ((float)pCurZone->GetNumContacts())/(float)(K*2); // First calculate users assuming the tree is full.
// Modify count by bin size.
// Modify count by how full the tree is.
// Modify count by assuming 20% of the users are firewalled and can't be a contact.
return (UINT)((pow(2.0F, (int)m_uLevel-2))*(float)K*fModify*(1.20F));
}
float fModify = ((float)pCurZone->GetNumContacts())/(float)(K*2);
if "GetNumContacts()" means the number of the list in the tree.Is "K*2" means the two k-bucket?Is it means one tree use two k-bucket?
