Ethernet point-to-point lines can transfer many types of information from one location to another efficiently. This includes video streaming, access to central data centers, video conferencing, email communication, and voice (telephone) traffic. Point-to-point has traditionally enjoyed the reputation of being the most secure bandwidth circuit between two locations. However, with advancements in encryption technology and because MPLS (multiprotocol label switching) is maintained over the private network of telecom providers, many consider MPLS to be as secure as point-to-point. Because of this, many major businesses, like bank chains, now routinely trust their important information transfers to MPLS networks.
