MPLS TECHNOLOGY: AN INTRODUCTION TO QoS
IZR is a leading supplier of ADSL based MPLS IP VPNs and the one of the first to market with a Quality of Service (QoS) enabled contended ADSL MPLS IPVPN, known as QoDSL VPN.
Historically, businesses requiring network connectivity for delay sensitive,real-time applications like voice over IP (VoIP) have been limited to costly leased lines or, for smaller sites, dial-up connections. Even though ADSL has become commonplace, it has not been adopted for these sorts of applications because the lack of a service level guarantee on ADSL services makes the actual bandwidth available at a given time too unreliable.
However, the development of QoDSL IP VPNs means that this is no longer true. A QoDSL IP VPN is now a low cost, reliable bandwidth alternative to leased lines. It makes the provision of applications like VoIP cost effective to small sites and even individual home workers.
Organisations of all sizes can now run delay sensitive, real-time applications typically served by expensive leased lines over an inexpensive contended broadband infrastructure. Applications that benefit from QoDSL include:
