With a VPN, it’s simple to get around blocks on BitTorrent, Skype as well as other programs put in place by ISPs like Rogers and Comcast.
Increasingly, Internet companies are employing a technique called traffic shaping to attempt to control what their customers do with the link they paid their hard-earned money for. With the anonymous VPN service, it’s possible to circumvent the blocks on services like Skype and BitTorrent set into position by Comcast, Rogers among others.
How does traffic shaping work?
To the implications of traffic shaping on consumers (and, concurrently, find methods to evade such shaping), it is vital that you know how traffic shaping works to block or slow down Internet traffic.
Canadian providers, most notoriously Rogers, have implemented harsh traffic shaping policies in an effort to prevent peer-to-peer file sharing on their networks. Rogers has gone so far as to block encrypted traffic of any form and, at one point, block the download of files with a .torrent extension. That is usually done through QoS (quality of service) hardware in the ISP’s end and, hence, is hopeless to circumvent without using a VPN service like Blacklogic. In the case of Rogers, such extreme traffic shaping caused an extensive backlash and tarnished the company’s reputation, perhaps permanently, as customers went in droves to service providers that gave them the bandwidth and access they pay money for.
Comcast, Sandvine and packet forgery
To not be outdone, Comcast, the biggest broadband provider in the United States, began shaping users’ BitTorrent traffic in 2007 employing a system called Sandvine. Insidious and dishonest, Sandvine really injects its own data right into a user’s BitTorrent session. This operation is worse than traffic shaping, as it’s real forgery of a valid user’s data. By sending TCP RST (reset) packets to peers in a torrent swarm, a user is effectively prevented from seeding a torrent file without resorting to high-level encryption which is not supported by all torrent clients. This slows down the download for everybody involved.
Getting around traffic shaping using a VPN
While there are means around most traffic shaping and filtering, they are generally unreliable and hinder transport speeds so much as to be unusable. The simplest way to get around traffic shaping is by using an unattributable VPN. Services like Blacklogic were designed with downloading in mind. Using a Blacklogic VPN, for instance, is the same as sitting at a pc in Canada, where Blacklogic’ servers are located. Torrent files can seed, Skype can make calls, and blocked sites are unexpectedly unblocked, not forgetting that the access provided is totally anonymous. Whether you are being blocked by Rogers, Comcast or another ISP, a VPN is the only 100% reliable approach to get around BitTorrent, Skype along with other traffic shaping.
The last word on Sandvine and traffic shaping
As long as you are not doing anything illegal, your service provider has certainly no right to try to restrict that which you do with your link that you paid for. Should you can not send them a message by switching to a different ISP, use a VPN and get around their draconian blocks.
