Vagaa
Encyclopedia
Vagaa is a peer-to-peer
program originating from Mainland China
. The software is compatible with eDonkey network
and BitTorrent and can be used for downloading large files, however as it has been blocked from most eDonkey servers, its usefulness has dropped in the past years. The software is being developed by users from Mainland China and has special support for some techniques utilized on complicated LANs.
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.
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.
. Therefore, Vagaa has violated the GPL Open Source
License by not offering the code of their product to download.
In additional, the search mechanism of Vagaa did not make use of any special algorithm to speed up searching and indexing, but instead it achieved this optimization by spamming/bombarding the servers in question. Therefore, most of the servers on the eDonkey network refuse connections from Vagaa to maintain their system stability, which greatly reduces the usability of the client.
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 received a DDoS attack. Then, the software company apologized in public and promised to provide an updated version of the software with the problem solved. However, the updated version did not stop its bad behavior according to a comparison testing among official eMule
