Though enormous improvement has occurred in the field of transmission media layer for which gigantic amount of data can be transferred but there is bottleneck problem at the upper layer protocol stack so that eventually the data transmission process becomes slower. Data may be transferred by optical fiber as a physical media which have large bandwidth but at the intermediary system the O-E-O process is accomplished for routing purpose which makes the system slower. At the intermediate nodes there are also buffering problem for this conversion. So beneath the IP layer a process called MPLS is proposed for removing the extra processing at the intermediary system.
