The present invention relates to a method and an apparatus for measuring and managing user quality of experience in a network, and a system for measuring user quality of experience in a network may comprise: a system controller for configuring measurement criteria for user quality of experience between network elements and controlling so that the network elements measure the user quality of experience according to the set criteria; a network element for transmitting a packet to a counterpart network element in order to measure, according to the control of the system controller, the user quality of experience for at least one counterpart network element; and a counterpart network element for receiving the packet from the network element and transmitting a response packet.

Method and apparatus for managing user quality of experience in network

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). A controller and a switch for network failure relieving from a software-defined networking (SDN) is provided. A method for operating the controller includes: transmitting, to the switch, path information for at least one packet and a session establishment message to establish a session for detecting a link failure of the at least one packet based on information regarding a capability of detecting a link failure of the switch. The method also includes receiving, from the switch, a session status message regarding a status of the session. If the status of the session is identified as the link failure, updated path information for the at least one packet based on information of the session is transmitted to the switch.

Method for operating controller and switch for relieving network failure from SDN, and controller and switch therefor

An operation method and apparatus in a first end device of a service provider network is provided. The method includes generating a measurement frame including information supporting simultaneous measurement of a plurality of Service Level Agreement (SLA) metrics, sending the generated measurement frame to a second end device connected through the service provider network, receiving a reply frame corresponding to the generated measurement frame from the second end device, and analyzing the received reply frame and hierarchically acquiring the plurality of SLA metrics for the second end device.

Method and apparatus for measuring end-to-end service level agreement in service provider network

A method for measuring an end-to-end Service Level Agreement (SLA) in a network having entities of different mobile communication networks is provided. The method includes sending a server a test condition for SLA measurement, sending the server a test packet, obtaining from a test result received from the server parameter values for metrics included in the test condition, generating analysis data based on the test condition, and sending the analysis data to a manager unit for the entities based on the test condition.

Method and apparatus for measuring and managing end-to-end service level agreement in network having entities of different mobile communication networks

A method for performing Software Defined Network (SDN)-based network sharing by a controller to support multiple operators is provided. The method includes configuring a plurality of flow tables in which an independent packet processing operation policy is defined per operator; and transmitting the plurality of configured flow tables to a network equipment, to establish an independent packet processing operation policy per operator in the network equipment.
