Cloud and Edge Computing

This Recommendation specifies the requirements and capabilities of data aware networking (DAN) to realize the use cases and scenarios described in ITU-T Supplement 35 to Recommendation Y.3033, Data aware networking - Scenarios and use cases, which are expected to be major applications/services provided on DAN. One of the objectives reflecting emerging requirements for future networks (FNs) is data awareness as specified in ITU-T Recommendation Y.3001 - Future networks: Objectives and design goals. DAN is expected to have capabilities optimized to handle enormous amount of data and to enable users to access desired data safely, easily, quickly, and accurately, regardless of their location by making information the destination of request delivery. DAN can be rephrased as the networking whose central concern is retrieving information, i.e., information centric networking (ICN).

This Recommendation defines a cloud storage architecture in visual surveillance. Cloud storage enables the service users to have ubiquitous, convenient and on-demand network access to a shared pool of the configurable storage resources, which can be rapidly provisioned and released with the minimal management effort or service-provider interaction. Cloud storage can realize flexible and reliable data storage for large-scale visual surveillance, and its components are modularized and allocated dynamically based on the real usage. This Recommendation provides the architecture, entities, reference points and service control flow for cloud storage in visual surveillance.

The document studies the security enhancements on the support for Edge Computing in the 5G Core network defined in TR 23.748, and application architecture for enabling Edge Applications defined in TR 23.758 and TS 23.558. Potential security requirements are provided and possible security enhancements to 5GS and edge application architecture are proposed that meet these security requirements.

IEC 62541-100:2015 is an extension of the overall OPC Unified Architecture standard series and defines the information model associated with Devices. This part of IEC 62541 describes three models which build upon each other: - the (base) Device Model intended to provide a unified view of devices; - the Device Communication Model which adds Network and Connection information elements so that communication topologies can be created; - the Device Integration Host Model finally which adds additional elements and rules required for host systems to manage integration for a complete system. It allows reflecting the topology of the automation system with the devices as well as the connecting communication networks.

The document studies the potential use cases, requirements, and solutions for the management of edge computing architecture and requirement defined by TS 23.558 and TS 23.501. The document provides conclusions and recommendations on the next steps in the standardization.

The present document studies the charging aspects of Edge Computing based on architecture, procedures and information flows for enabling Edge Applications over 3GPP network as well as capabilities for 5GS to support edge computing. The investigation includes different charging scenarios with potential business requirements, alternative solutions with potential impact on charging architecture, charging functions and charging procedures.

The document is a technical report capturing the study on application architecture for enabling edge applications over 3GPP networks. The aspects of the study include identifying architecture requirements (e.g. discovery of edge services, authentication of the clients), supporting application layer functional model and corresponding solutions to enable the deployment of applications on the edge of 3GPP networks, with no impact to edge-unaware applications on the UE and minimal impact to edge-aware applications on the UE.

The document specifies the application layer architecture, procedures and information flows necessary for enabling edge applications over 3GPP networks. It includes architectural requirements for enabling edge applications, application layer architecture fulfilling the architecture requirements and procedures to enable the deployment of edge applications.

The document studies: a) the complete harmonization and merger of the policy control and flow based charging architecture and procedures; b) possible architectures and solutions for adding end-user subscription differentiation and general policy control aspects to the policy- and charging control; c) alternative solutions for binding bearers to services (provided today by the authorization token). This includes studying solutions for the network to control bearer usage by service flows.

The Technical Report studies and performs evaluations of potential architecture enhancements to support Edge Computing (EC) in the 5G Core network (5GC). Specifically, two objectives are included: a) to study the potential system enhancements for enhanced Edge Computing support, and b) to provide deployment guidelines for typical Edge Computing use cases, e.g. URLLC, V2X, AR/VR/XR, UAS, 5GSAT, CDN, etc.

The document provides a glossary of terms relating to the conceptual, architectural and functional elements within the scope of work on Multi-access Edge Computing. The purpose of this glossary is to ensure that all terminology defined in the document is used in a consistent way by all ETSI MEC deliverables as well as in wider industry discussions on Multi-access Edge Computing.

The document focuses on the support of regulatory requirements for Lawful Interception (LI) and Retained Data (RD) when implementing MEC into the network. It describes the problems, constraints, interfaces and additional capabilities needed for the different deployment scenarios, to ensure full support of LI and RD regulatory requirements when implementing MEC.
