about the CA from wiki source :
The Client Analyzer (or CA) is a project of the German modder Wizard. This system has the goal of recognizing Leecher as do alternative systems to the IC, such as AntiLeechClass always wizard (for example, contained in Ionix), the DLP Xman (Xtreme) or the Argos to Xanatos (NeoMule) .
The CA creates a ranking of conduct based on heuristics which is to give a more complete picture on the clients and their real identity.
[edit] Operation
The Client Analyzer does not block tags, nicknames or modstrings, analyze first the behavior of the client, thus making possible a fair treatment of all customers by behavior. So, for example-Spammer Mod as ketamine, but also customers, who download a lot without posting, will be punished by the CA.
Some aspects of the CA Exchange:
* How long a client is known someone (who retains his Hash-user gets a small bonus);
* Report DL: UL;
* What kind of UL / DL's state (files complete, incomplete, rare);
* If you use a nickname stolen, a sequence mod stolen or corrupted files are sent;
* If requests are made too quickly (client-aggressive);
* If requested source can be done too often and / or ignoring the requests received.
Each client has a chance to be punished, rehabilitated, this is one of the biggest advantages of CA, in practice, a client identified as incorrect, if you send files to upload to the network is rehabilitated and no longer banned / penalized (this does not happen in other systems other than CA where clients are banned inevitably "lost" even if they could send files to upload, this is both unfair and unnecessary).
Rehabilitation is effective when we receive from these clients banned / penalized for chunks, which vary according to the penalty in the case of Mod that steal Nick, the penalty is 5 chunk to return to 'normal' level.
The idea behind the CA was a Wizard and update the list leecher for the umpteenth time. Alternative systems to the IC have some disadvantages:
* Must be constantly updated;
* High consumption of CPU (because of continuous monitoring);
* Block / sanction to all Bad-Mod blacklisted in some cases even if they are "useful" to the network (sending files to upload).
* Are sometimes punished releaser.
