摘要： Provided is a method and system for providing a QoS in a broadband convergence network deploying a mobile IP. In the method, a service and policy is defined at a first network design stage for guaranteeing the QoS of the broadband convergence network. QoS parameters corresponding to the defined service and policy are reflected in a DSCP field corresponding to the defined service. The DSCP field and the QoS parameters are applied to an access router in a management network. Accordingly, the QoS can be guaranteed to be suitable for the service and policy and a seamless handover guaranteeing the QoS can be provided.

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.
