摘要：Multiprotocol Label Switching (MPLS) is a differentiated and scalable framework introduced by IETF, which uses simple configuration & management to deliver end -to-end IP services. It enables the network devices to specify path based on Quality of Service (QoS) and bandwidth requested for those applications by changing the hop -by-hop paradigm. Fault tolerance is the ability of the system to respond gracefully to an unexpected hardware or software failure. By using fault recovery techniques we can make MPLS network fault tolerant. Traditional IP networks have many limitations such as routing tables, which can be complex and time consuming. These limitations affect the perform ance of the network in some applications of triple play services (i.e., voice, video and data) which may be delay sensitive applications. Thus, the main impetus behind Multi Protocol Label Switching (MPLS) technology proposed to speed up the traffic flow in the network using labels.
