MPLS and traffic engineering in IP networks

摘要: Rapid growth and increasing requirements for service quality, reliability, efficiency have made traffic engineering an essential consideration in the design operation of large public Internet backbone networks. addresses issue performance optimization operational A paramount objective is to facilitate transport IP through a given network most efficient, reliable, expeditious manner possible. Historically, has been hampered by limited functional capabilities conventional technologies. Recent developments multiprotocol label switching (MPLS) differentiated services opened up new possibilities address some limitations This article discusses applications MPLS
