END-TO-END SERVICE LEVEL AGREEMENT MEASUREMENT METHOD AND APPARATUS IN A SERVICE PROVIDER NETWORK

摘要

The purpose of the present invention is to provide a method and device for measuring and managing an end-to-end service level agreement (SLA) by using improved Y.1731 PM in a service provider network providing a mobile communications network based on L2. A method for operating a first end-to-end device to measure the end-to-end SLA includes: a step of generating a measuring frame including information supporting simultaneous measurement of a plurality of service level metrics; a step of transmitting the generated measuring frame to a second end-to-end device connected through the network; a step of receiving a response frame corresponding to the generated measuring frame from the second end-to-end device; and a step of hierarchically obtaining the service level metrics on the second end-to-end device by analyzing the received response frame.
