G3T’s patented e2e Technology is essentially a bolt-on server software incorporating a light-weight protocol enabling full NAT traversal. This means that the once the communication is set-up over the internet between two IP devices, regardless of whether or not they are behind routers, then the subsequent multi-media data traffic go directly between these two IP devices, without having to be hosted by the Service Provider.
This means enormous savings in bandwidth traffic into and out of the relevant VoIP (or other) Service Provider; bearing in mind that these internet calls can be of unknown length and are invariable free to the user.
Furthermore, as the Service Provider/Operator deploying e2e Technology does not have to host the internet only traffic, they can conduct call set-up in a tremendously large number of instances compared with current methods.
The e2e Technology has been successfully deployed in a VoIP environment, but can be applied to all forms of multi-media traffic (e.g. video, music, IPTV etc.).
An ever more common situation globally, is for access to the internet to be through the use of routers, which permit multiple clients behind the router to access the internet as required. These routers apply network address translation to control the connectivity of multiple IP devices through one IP connection to the internet.
Where both devices that wish to communicate with each other are behind their respective (NATed) routers, then there is difficulty in getting the communication path set-up directly between the two IP devices over the internet. To guarantee resolution of this Network Address Translation problem when SIP servers are used, then the Service Provider has to deploy Session Border Controllers. However, the big downside is that the Service Provider will have to host all the data communication traffic for the whole duration of the call.
In the early days of Broadband/ADSL, access to the internet was via an ADSL modem enabling a single IP device to access the internet.
Where such a situation still exists, each IP device will be associated with a corresponding single IP address on the internet. So the setting up of a communication between these devices is straightforward using, say, SIP servers. Once the call is set-up, all data traffic goes direct between the IP devices; a situation that also applies if the recipient device is the ONLY device that is connected to the internet by an ADSL modem.
Unfortunately, this set of circumstances is not often the case and is becoming less common.
