website = [http://www.vagaa.com www.vagaa.com]Vagaa(哇嘎) is a
peer-to-peer (P2P) program originating fromMainland China . The software is compatible witheDonkey network and BitTorrent and is often used for downloading large files such as movies, games and drama series. Also users share their files in Vagaa network. The software is being developed by users from Mainland China and the most fit tools for complicated network, like NAT, NAPT users.Vagaa has some special soft router algorithms library, which speed downloading and uploading, even between the NAT users. Also the famous distributed search system. The search function is quick and full of multi-language content from users.
Use of this software is often frowned upon by server operators for its overly-aggressive and almost faulty stress exerted on the respective server and sometimes result in the banning of Chinese users.
Mechanism
The company produce the Vagaa software suggested that Vagaa borrowed technology from eDonkey2000, BitTorrent and Kad that by applying proprietary distribution routing technology, high connectivity and stability is maintained. In additional, the application of
Keywords Smart Analysis technology allowed proprietary distributive searching and indexing made the searching speed much higher than other competitive products. Vagaa is also the first product produced by Mainland Chinese to allow viewing of VOD downloading.Criticism
Critics suggested that Vagaa is made from the modification of the famous GPL P2P software
Shareaza . Therefore, Vagaa has violated the GPL by making their product a proprietary one.In additional, the mechanism of Vagaa did not make use of any special algorithm to speed up searching and indexing, but by spamming and bombarding the servers. Therefore, some servers refuse connections from Vagaa to maintain their system stability.

On
12 August 2006 , the famous P2P network DonkeyServer made the following announcement:quote|
server version 17.12 (lugdunum)
Note to Chinese users of this server.
It seems many Chinese people use a modified eMule that abuse servers.
Unfortunately we cannot tell what is the name of this mod.
This *buggy* version sends automatic searches, over and over and servers suffer a LOT
Please use standard emule program 0.47a, or we will be forced to deny access
to this server for *all* Chinese people. That would be bad :(
Thank you
Note : eMule 0.47a is here : http://www.emule-project.net/download
Note : If you already use a standard 0.47a eMule, or a mod based on 0.47a,
please ignore this message. Have Fun
However, DonkeyServer did not mention about which P2P was causing the problem, as well as their version numbers.On
13 August 2006 , cnBeta.com, a famous IT News portal in Mainland China summarized the information collected and suggested it was Vagaa that caused the system instability. After that, the Vagaa official website receivesDDoS attack. Then, the software company apologized in public and promised to provide an updated version of software with such problem solved. However, the updated version did not stop its bad behavior according to a comparison testing among official emule release, verycd.com mod release and vagaa, on one of the famous IT News portal www.it.com.cn (see reference 1)References
