Some Weak Encoding Of Internet Speed Accelerator
All the known fact is that by transferring through the satellite of the data, which go to you, the same data can be received by any person with a plate and dvb card adjusted on the concrete satellite, which fact is unpleasant enough. In particular, there are a number of programs, which allow receiving together with you files that you download on the satellite - without paying and without your consent.
At work through the accelerator the transfer by the ground and by the satellite goes in its own format, which though does not cipher the traffic, but will transform and compresses it. The problem with the hackers considerably becomes complicated, if he lose even one package, besides it is necessary to know the algorithm of decoding. Such method at all should not be trusted at need for real enciphering the traffic, but if such need is not present, this method will be good for most of the users.
Reduction of the channel latency at a plenty of simultaneously working sessions is another weak side of the accelerator. At work in several sessions in one package transferred from the accelerator server of the client can be data from 10-16 sessions. Thus there will be an effect of reduction MRU without increase in an overhead charge turns out.
The reduction of the direct traffic is caused by more optimum algorithm of transfer and by compression of the channel.
Both optimisation of the channels and application of compression allow saving a signal from the satellite approximately - at the standard work of users and there is an economy in 20-30 % from the channel without an accelerator. At the archive uploading you do not receive almost no economy, but you will receive essential economy at uploading binary /texts / html / not compressed pictures. The combination of these two extreme measures also gives experimentally 20-30 % of economy.
As at any intermediate link, the increase in instability of the general system, impossibility of use of the accelerator inside of the "iron" routers with closed initial code, inability of its work (in the current version) as full analogue of standard VPN, as it is accelerated only in TCP the traffic, absence of an encoding of the traffic in the current version. At present time there is a development of the second generation of an accelerator, in which these lacks will be eliminated.
