METHOD AND APPARATUS FOR MEASURING LABEL SWITCH PATH PERFORMANCE PARAMETERS USING PERFORMANCE MONITORING OPERATION AND MANAGEMENT PACKET IN MULTI-PROTOCOL LABEL SWITCHING NETWORK

摘要

Provided is a method and apparatus for measuring performance parameters of a Label Switch Path (LSP) using an Operation & Maintenance (OAM) performance monitoring packet in a Multi-Protocol Label Switching (MPLS) network, and more particularly, a method and apparatus for measuring packet loss, packet transfer delay, and jitter of an LSP set between two Label Switch Routers (LSRs) using an MPLS OAM packet. Accordingly, the present invention can overcome the limitation that existing MPLS OAM technology is dedicated to only identify malfunction of an LSP, and by also adding parameters (packet loss ratio, packet transfer delay and jitter related to SLA to a payload of an MPLS OAM packet as new required fields, provides a performance measurement method capable of measuring SLA performance parameters based on the newly added fields.
