MPLS IP VPNs offer the benefits of true convergence, allowing multiple applications to share a single network infrastructure.

One of the main drivers for MPLS IP VPN implementation today is the imminent or future roll-out of IP telephony. Voice telephony usually has a true any-to-any requirement, IP telephony is an ideal application for raising a business case for an MPLS IP VPN migration or implementation.

Other applications which can run across MPLS IP VPNs:

• Intranet connectivity
  
• E-mail
  
• File sharing
  
• Internet access (usually across a corporate gateway at the main site)
  
• Access to other web based applications
  
• Access to legacy applications (may require legacy protocols to be encapsulated in IP)
  
• Online learning
  
• Backup / Disaster Recovery connectivity
  
• Broadcast / Multicast
  
• MPLS can support connecting very to a large number of sites.
