Improving VoIP Delivery with Broadband Bonding
VoIP Quality of Service
VoIP is just one example of how we can repurpose the Internet to suit our needs. In the early days, no one thought that such a network could be used to carry real-time voice communications. Indeed, the initial dial-up networks supported VoIP with much difficulty. It wasn't easy to obtain a quality connection without the call constantly breaking up. In a way this difficult time set the stage for VoIP innovation since engineers had to devise more and more efficient algorithms to reduce the bandwidth used by Internet-based voice calls.
Though in today's world we have more than enough bandwidth to support high-quality audio over the Internet, these same techniques are serving us well and reducing the footprint of VoIP even further. Most clients now automatically select the best audio codecs to use and seamlessly configure themselves in order to bypass the NAT firewalls that they usually need to deal with in a typical LAN set up. Through the use of innovative techniques like STUN servers, TURN servers etc., it's possible for a client behind a NAT firewall the project it's directly reachable IP address.
One technique that is coming into greater use especially in the corporate world is known as broadband bonding. It has the potential to significantly improve the quality of service of all Internet-based applications especially VoIP.
Understanding Broadband Bonding
Many companies have redundant connections to the Internet. Unlike in a residential home, a corporation cannot afford to be off-line for even a few minutes. Doing so would incur a significant loss of revenue and productivity. Unfortunately there is no default way to pool the resources of the various Internet providers together. So say you are trying to upload a large file, the entire process will have to be carried out on one broadband connection. This means that the effective upload and download bandwidth speeds are a fraction of what is totally available to the organization. Say for example that you have three net connections each at 10 Mbps. Though your total available bandwidth is 30 Mbps, you will never be able to achieve more than one third of that through any single service.
Through the power of broadband bonding, all three of these connections to the Internet can be pooled together to obtain a total of 30 Mbps. The service that provides such bonding facilities will break up a chunk of data into several pieces and sent each over a different net connection and then reassemble them at their data center thereby effectively making all of your Internet connections behave as one.
Contact your business VoIP customer support to find out how you can implement broadband bonding in your own organization. Hosted VoIP services will particularly benefit from this kind of technology and will significantly improve the redundancy and quality of your communications network.
