INTRODUCTION
A network could be designed considering initial
factors, but network conditions such as load and
traffic characteristics change with time. Network
resources also vary due to new resource requests
or topology changes (e.g., node or link failures).
One important part of designing a quality of ser-
vice (QoS) network is the reliability of the net-
work. This reliability could be provided with
different fault management mechanisms applied
at different network levels and timescales. Multi-
protocol label switching (MPLS) provides a fast
restoration method to recover from failures.
MPLS fault restoration mechanisms use backup
label switch path (LSP) establishment. With
these backups, traffic could always be redirected
when a failure occurs. MPLS also provides fault
detection and fault recovery actuation faster and
