Why do I need Multiprotocol Label Switching (MPLS)?
MPLS is rapidly emerging as the VPN solution of choice for medium to large multi-site enterprises for the simple reason it offers so may inherent benefits over other comparable technologies.
- High Reliability
MPLS VPNs are extremely resilient due to the fully meshed virtual cloud over which information is carried. If, for example, one link in this cloud fails, traffic is automatically redirected over another path.
- Access Independence
MPLS can be integrated seamlessly over any existing infrastructure, such as IP, Frame Relay, ATM, or Ethernet. Subscribers with differing access links can be aggregated on an MPLS edge without changing their current environments, as MPLS is independent of access technologies.
- High Bandwidth
MPLS makes high bandwidth available cost effectively. Moreover, this bandwidth can easily be turned on and off, as requirements dictate ensuring that any investment in your network is future-proof.
MPLS supports traffic engineering (ability to differentiate levels of service and prioritize delay-sensitive traffic), and Quality of Service (QoS) capabilities which makes it the perfect transport technology for converged (voice and video) networks.
