摘要： Provided are an apparatus and method for managing quality of a multi protocol label switching (MPLS) label switched path (LSP), which has been previously established in a convergence network. The apparatus for managing quality of a LSP includes: LSP provisioning/releasing means for provisioning and releasing the LSP in a convergence network; and LSP quality management means for measuring the quality of the LSP on the basis of performance information received from the each node through which the LSP passes, wherein the LSP quality management means transmits alert information to the LSP provisioning/releasing means, when the measured quality of the LSP deviates from a predetermined performance threshold, so that the LSP is readjusted.

摘要： Provided is a method of constituting a highly reliable control network in an IP-based network environment and, more particularly, a protocol technology for automatic control channel constitution and protection. The method includes functions of protection group (PG)-1/3 control channel identification, detour control channel identification, an automatic switchover, a forced switchover, a control channel unavailability notice, a protection/switchover properties information inquiry, an Hello, a protocol error notice, and re-transmission. This invention provides a protection mechanism of control channels without additional overhead and with higher level of resilience capability to improve shortcomings of the LMP and MPLS based schemes.
