Looking into MPLS for your companies network?  Just what is MPLS?  MPLS (Multiprotocol Label Switching) is a networking technology directing and carrying secure data from one location to another. MPLS allows businesses to create virtual links between two or more locations within a Wide Area Network or (WAN ). . MPLS is a highly scalable, protocol agnostic, data-carrying mechanism. In an MPLS network, data packets are assigned labels. Packet-forwarding decisions are made solely on the contents of this label, without the need to examine the packet itself. This allows one to create end-to-end circuits across any type of transport medium, using any protocol. The primary benefit is to eliminate dependence on a particular Data Link Layer technology, such as ATM, frame relay, SONET or Ethernet, and eliminate the need for multiple Layer 2 networks to satisfy different types of traffic. MPLS belongs to the family of packet-switched networks.
