The article offers information on Multi Protocol Label Switching (MPLS), which can carry many types of traffic including IP packets, native ATM, Ethernet frames, and SONET. It is said that the popularity of MPLS is driven by the need to support VoIP and video-conferencing, and other time sensitive technologies. However, it is said that the cost of flexibility and performance of MPLS is the loss of visibility into network performance and the difficulty of securing every location in the MPLS mesh. It is cited in the article that one of the possible solutions for the issue is to enable and collect NetFlow to monitor all MPLS traffic. NetFlow is an IP accounting technology designed to run in a small footprint aboard network routers.
