Detailed information on the evolution of SONET/SDH transport networks to more efficient packet transport networks based on MPLS Transport Profile (MPLS-TP).
Packet-based services are experiencing fast growth and now start to dominate the carrier traffic mix (driven by video, cloud and migration to IP). Packet services have also evolved to more dynamic traffic patterns (driven by mobile and cloud services). Traditional transport networks have relied on circuit technology and are rapidly becoming inefficient to carry packet traffic.
We’ll take a look at how new extensions to MPLS define a transport profile (MPLS-TP) that introduces packet technology while maintaining their traditional operational model. MPLS-TP enables the migration of SONET/SDH networks to packet technology in order to achieve better bandwidth efficiency and flexibility.
