A method and system of deployment of a virtualized service on a cloud infrastructure while taking into consideration variability/elasticity of the cloud resources are described. A first service function specification is selected. Candidate computing systems and candidate links are determined. The determination of the candidates is performed based on the availability and characteristics of the computing systems and the network resources in the cloud infrastructure which includes varying characteristics. A first computing system and one or more links are determined from the candidates for placing the first service function in the cloud infrastructure.

Joint consideration of service function placement and definition for deployment of a virtualized service

A method and system of deployment of a virtualized service on a cloud infrastructure are described. A first service function specification of a first service function is selected. A determination of a set of the computing systems and a set of the links is performed based on availability and characteristics of the computing systems and the network resources in the cloud infrastructure, A selection of a first computing system to be assigned to host the first service function and links is performed based on the first service function specification. In response to determining that there is one or more the service functions that are not yet assigned, the selection of the service function and the determination of the computing system and links are repeated for each remaining functions until all of service function are assigned to computing and networking resources in the cloud infrastructure.

Methods and apparatus are provided. In an example aspect, a method of storing data in a communication system is provided. The data comprises n data blocks, and k data blocks of the n data blocks are required to recover the data. The communication system includes a plurality of clusters of data storage nodes including a first cluster that is a closest cluster of the plurality of clusters to a source of the data. The method comprises receiving, from a node associated with a respective network operator of each of the clusters of storage nodes, information identifying the data storage nodes that are in each of the clusters. The method also comprises causing each of at least k data blocks of the n data blocks to be stored in a different storage node in the first cluster.

Managing data storage in a communication system

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.
