Multi-Protocol Label Switching (MPLS) is rapidly emerging technology,
which plays a key role in next generation networks by delivering QoS and
traffic engineering (TE) features. MPLS is helpful in managing traffic
when some links or paths are under and/or over utilized. Traffic
engineering is the main strength of MPLS. Where an IP-based network is
connectionless, MPLS based network defines definite paths for network
traffic based on some Quality of Service level. In MPLS a look - up in
switching table is certainly less complex and less time consuming than a
corresponding routing table look-up in an IP router. This book presents
an analysis of MPLS signaling protocols for traffic engineering and
shows the capability of providing traffic engineering in MPLS compared
to the conventional routing protocol, and also explains the MPLS LSR
operations based on the basic LSR functionality of classification,
queue, and scheduling. After comparative analysis of MPLS and non-MPLS
network it shows that MPLS provides improved network performance for
heavy traffic environments. This is useful to professionals and
researcher who are working on MPLS networks.
