Multiprotocol Label Switching is an IP-enabling technology that integrates Layer 2 information about network links (bandwidth, latency, and utilization) into Layer 3 (IP) within a particular ISP to simplify and improve IP-packet exchange.

Vivace's suite of MPLS switching solutions have been designed as a solution to help manage the fastest type of infrastructure presently in place - namely IP. MPLS enables IP networks to handle legacy traffic in all its forms, from all Ethernet, Frame Relay, ATM and SONET while eliminating 'fiber exhaust', a fundamental problem for IP transport networks. Key applications of MPLS technology include traffic management/engineering, virtual private networks (VPN) and Quality of Service (QoS).

Traffic Engineering - using MPLS, service providers are now able to minimize congestion by distributing traffic in a controlled manner. Traffic management simplifies network operation, administration, maintenance and provisioning (OAM&P).

QoS - refers to network throughput levels. One of the main advantages of MPLS is the ability to guarantee network capabilities in both quality and speed.

VPN - using MPLS, service providers can create IP tunnels throughout their network, without the need for encryption or end-user applications.
