A method for improving user experience associated with an application supported by a system is provided. The method comprises obtaining input data associated with a group of one or more features and determining a performance score associated with the obtained input data using a performance score generating model. The performance score indicates an estimated quality of user experience (QoE) of the application. The method further comprises determining whether to apply a configuration change based on the determined performance score. The configuration change is associated with the application and/or the system.

Modelling and optimization of quality of experience

A computer-implemented method for aggregating and exposing infrastructure capability information is provided. The method includes extracting infrastructure capability information, wherein the infrastructure capability information includes available resource types and, for each available resource type, first attribute information including a first attribute name and a first attribute value. The method further includes, for each available resource type: determining whether the first attribute value is a literal type attribute value or a numerical type attribute value; for an attribute value determined to be the literal type, aggregating the first attribute information to generate aggregated literal attributes information; and for an attribute value determined to be the numerical type, aggregating the first attribute information to generate aggregated numerical attributes information. The method further includes receiving a request for a resource including requested resource types and, for each requested resource type, second attribute information including a second attribute name and a second attribute value. The method further includes, for each requested resource type: determining whether the second attribute value is a literal type attribute value or a numerical type attribute value; for an attribute value determined to be the literal type, processing the second attribute information to generate processed second attribute information and comparing the processed second attribute information with the aggregated literal attributes information to determine whether the requested resource matches the available resource types; and for an attribute value determined to be the numerical type, comparing the second attribute information with the aggregated numerical attributes information to determine whether the requested resource matches the available resource types.

Method and apparatus for infrastructure capability aggregation and exposure

A method for steering an original packet transmitted by a UE. The method includes receiving a first packet, wherein the first packet encapsulates the original packet. The method also includes extracting networking information (e.g., IP source, IP destination, tunnel identifier) from the first packet. The method also includes generating an SFC header (e.g., an NSH header), wherein the SFC header comprises: i) an SPI that identifies a service path and ii) metadata, wherein the metadata comprises the networking information extracted from the first packet. The method also includes generating a second packet comprising the SFC header and the original packet. The method also includes providing the second packet to an SFF that is configured to select a service path based on the SPI included in the SFC header of the second packet and forward the second packet based on the selected service path.

Radio access network (RAN) architecture

Systems and methods for generating and using a placement map for a distributed storage system are disclosed. In some embodiments, a method for a client node to perform a read/write operation in a distributed storage system comprises obtaining a number of server nodes comprised in the distributed storage system and an object name of an object for which a read/write operation is to be performed and creating at least a portion of a three-dimensional (3D) placement map for the object. The 3D placement map defines candidate locations for replicas of the object on the server nodes. The method further comprises applying policies to the at least a portion of the 3D placement map to provide at least a portion of a modified 3D placement map and performing the read/write operation for the object in accordance with the at least a portion of the modified 3D placement map.

Datafall: a policy-driven algorithm for decentralized placement and reorganization of replicated data

A node is provided. The node includes a receiver configured to receive data from an application. The data includes at least one of an expected workload on a dataset by the application and at least one expected characteristic of the dataset. The node includes a processor. The node includes a memory containing instructions, executable by the processor, that cause the processor to: compare the received data to a multiple storage backend configurations, select a storage backend configuration from the multiple storage backend configurations based on the comparison, cause creation of the dataset in a first storage backend having the selected storage backend configuration, determine performance data associated with at least one of performance of the first storage backend and actual workload on the dataset by the application, and modify at least one storage parameter of the first storage backend based on the determined performance data.
