Abstract
Label Switched Paths (LSPs) in a MPLS network sometimes fail to deliver user traffic in the condition of the connection fault. In this case, control messages are exchanged among nodes, and the fault is notified. Nevertheless, there is a need that this fault such as traffic black holes or misrouting should be detected and isolated by the users in MPLS network. For this purpose, the ping and the traceroute especially for MPLS were proposed in the IETF. In this paper, we describe how this proposal is implemented in our test bed and the detail algorithm of this proposal is introduced. Finally, we show how our algorithm test is conducted in our network.
