Multiprotocol Label Switching (MPLS) was designed to perform fast switching in the core of the network and allow for traffic engineering and quality of service (QOS) routing. Its main application is running Voice and Data over a single network. This paper intends to empower organizations to achieve the right technology and best economic deal. The complexity of configuration and the monthly cost of bandwidth per Mbps of MPLS are of concern. Virtual Private Network (VPN) is a secure tunnel that encrypts your data for transmission over a public network. While VPNs are quick and low cost to set up, they do add time delay (latency) and reduce the available bandwidth as the data is encrypted. A Private Wide Area Network (PWAN) allows multiple access technologies to be connected into a single secure network and allows the best price /performance technology to be applied to every location, increasing performance and lowering cost. For sites with large numbers of staff and very heavy voice traffic, MPLS or a similar technology with quality of service (QOS) is required. For sites with a low number of staff and light voice traffic usage, PWAN provide a cost effective solution. VPN and PWAN utilize technologies such as bonded ADSL providing upload bandwidth equivalent to MPLS offerings and provide 10-30 times the download speeds at half the cost of MPLS.
