Definitions
- the invention is located in a communications infrastructure allowing a client device to obtain a service developed from data from several storage spaces.
- the invention aims more specifically to make it possible to improve the quality of the service offered to the customer by allowing optimized routing of data between different entities.
- IDSA forum International Data Spaces Association
- IDS-Reference-Architecture-Model an architecture and mechanisms for data exchange between separate entities.
- One of the stones The cornerstones of such an architecture are based on certified "connectors" used to interconnect the different spaces maintained by the different partners.
- a connector is thus used to collect the data and deposit them in a storage space common to the members of the virtual data space, for example at the periphery of a communications network (edge).
- the virtual data space provides that each entity has at least one connector able to communicate with the connectors of the other partners of the virtual data space. Since the exchange of data must be secure, each connector must be able to be identified and authenticated in a secure manner and the connector of an entity must be able to ensure that the data it makes available is used by the other entities and in particular the client device in accordance with the data security specifications established by the respective providers of the virtual data space.
- a connector can be integrated into equipment of a fixed network or of a mobile network, indifferently. Once a connector has been identified, accepted and configured in the virtual data space and that it is known in particular to a data broker, the data exchange can operate .
- a data consumer in English Data Consumer also equipped with a connector requests the agent or directly one or more data providers (in English Data Provider) if he already knows them to transfer, recover, transform or obtain data from data providers.
- the data may itself include information relating to the policies for the use of this data and/or a general policy for the data exchanged between a consumer and a supplier for the data exchanged between these two entities.
- the provision of data may be accompanied by the provision of applications used by the connectors to perform data processing from an application.
- the provisioning of applications in the virtual data space is comparable to the provisioning of data except that the agent is identified as an application store (in English Applications Store).
- a connector can therefore request an application from a store according to its needs.
- identification and communication information exists, including IP addresses and communication ports used, but the data and/or application provider connectors communicate with the consumer(s). ) of data and/or applications in overlay mode, for example on the basis of tunnels, for example of the TLS type, established on the existing communications infrastructures or by using a protocol of the HTTPS type.
- This which does not allow on the one hand to establish a dynamic path between the connectors of the partners and on the other hand, the inherent characteristics of the communication networks, in terms of routing, quality of service, flow are not taken taken into account for the transfer of data in the virtual data space.
- the exchange of data in space is thus not optimized and the service based on the exchange of data does not benefit from a quality possibly adapted to the service consumed.
- the present invention aims to provide improvements over the state of the art.
- the invention improves the situation using a method of processing a data transport service in a virtual data space deployed on a communications infrastructure, the virtual data space comprising a plurality of sites comprising each a communication server, also called a connector, capable of hosting data or a data processing application, the method implemented by an optimization entity capable of communicating with the connector and comprising:
- a client entity or data consumer requests a data agent to identify servers, also called connectors, in charge of hosting some of the data requested by the consumer and/or connectors comprising an application capable of applying processing to requested data. Then, the consuming entity requests each connector to retrieve the data and apply the required processing to it.
- the processing method advantageously improves this solution by taking advantage of the transmission or connectivity characteristics of the communications infrastructure on which the virtual data space is deployed, but also by allowing data to be transported between the various connectors to allow recovery data and their processing in a short time.
- the method makes it possible to select connectors having a connectivity characteristic adapted to the data transport service, but also to avoid duplicating data by taking advantage of a chaining of the connectors in the development of the transport path of the data.
- updating the virtual data space by deploying new sites and/or new connectors as needed makes it possible to have a virtual data space adapted to the needs of consumers.
- the virtual data space can also be better organized by allowing the most common data processing operations, expressed in the transport service deployment requests received, to be carried out close to the connectors comprising the data. This data made available during previous offers and requests is thus taken into account by the optimization entity for the selection of processing functions in connectors and for optimizing their placement if new functions are to be deployed for a deployment request of data transport.
- the optimization entity implementing the processing method is thus new and inventive since it makes it possible to establish a routing path between different connectors making it possible to avoid the solicitation of a connector consuming data towards a plurality of data provider connectors and/or processing applications.
- the method thus makes it possible to aggregate the different data from different connectors, to apply a processing of this data or of part of this data as close as possible to the connectors where they are located and to route them according to a path improving the quality. of service of their routing thanks to a routing of the data of near closely between the connectors up to the data consumer or the client who issued the transport service deployment request.
- the processing method further comprises obtaining at least one identifier relating to the transport service of the deployment request received from among the following identifiers:
- identifiers from the data agent or directly from data providers and data consumers with regard to these identifiers makes it possible to determine the ordered sequence of connectors in an unambiguous way, in particular by using public identifiers such as FQDN names or IP addresses.
- public identifiers such as FQDN names or IP addresses.
- the use of a "Separation of Concern" data graph enriched with the identifiers of the connectors routing the data on the path makes it possible to be sure that the data has passed through connectors actually authorized to receive and process this data, guaranteeing that the data is not disseminated to unauthorized entities.
- the identifiers of the applications allow the consumer of the data to know which types of processing have in particular actually been carried out on the data received.
- the deployment request further comprises a rule associated with the data management policy of the transport service.
- a virtual data space makes it possible to be able to exchange data between entities and in particular for a "consumer” entity to be able to obtain data from different "suppliers", but the virtual data space must also make it possible to guarantee in particular to the data supplier that its data is not disseminated to unauthorized entities.
- the presence of rules associated with the data in the deployment request allows the entities responding to this request to ensure that the rules are compatible with their data management policies.
- the rules may correspond to retransmission rights, to rights only allowing dissemination of the data within the framework of the deployment request or even rules which authorize a wider dissemination of this data to other entities.
- the processing method further comprises obtaining an identifier of a provider of connectivity to the communications infrastructure associated with the identifier of the provider or of the consumer of data from the transport service obtained.
- an identifier of a connectivity provider in addition to an identifier of a data provider authorizes on the one hand to complete the identification graph of a data with not only the identifiers of suppliers and consumers but also with identifiers of connectivity providers of connectors to the infrastructure.
- a connector benefiting from connectivity with a supplier ensuring a high level of security for its transport infrastructure can improve the confidentiality of the data routed in accordance with the rules associated with the management policy for this data.
- the connectivity parameter comprises at least one transmission characteristic among the following characteristics:
- Different connectivity parameters of a connector to a communication infrastructure can be taken into account to ensure routing that complies with the needs expressed for example in the deployment request.
- the propagation time of a data packet in particular using ICMP type packets, or information on the bandwidth, total or available, that is to say that which can actually be used for the service data transport, are particularly relevant.
- the type of technology (Fiber, xDSL, 4G, 5G, etc.) used to attach a connector to the infrastructure provides information on the level availability and quality of the connection, on latency as well as on the security mechanisms associated with data transport.
- the processing method further comprises obtaining a software characteristic of an application required for the data transport service.
- the data transport service includes data, a path for transporting data, and applications performing processing of that data.
- the optimization entity can advantageously obtain, for example from a software agent (Software Broker), information concerning the licenses associated with the software used for the processing of the data, the processing times required for the data in accordance with the request of deployment received, as well as the characteristics of the entities required for the instantiation of software in the event that new applications must be instantiated for the transport service.
- the characteristics of the application may contain information on the volume of data which must be transmitted to the application so that the application can carry out these processing operations as well as the volume of data which the application must transmit. This information associated with the characteristics of data subscriptions via the data management agent can be useful for determining the bandwidth between the connectors and defining the quality of service that the connectivity operators must apply.
- the determination of the at least one path comprises the identification of a connector able to accommodate a data processing application in the virtual data space according to of the deployment request received.
- the optimization entity in the determination step, identifies the connectors capable of providing data and/or the entities capable of carrying out processing, for example by using the information obtained from the suppliers themselves or else by using its own previously obtained data.
- the path determined as the most suitable for guaranteeing a level of quality of service required for routing the data may require the deployment of new connectors, for example to deploy new processing applications.
- the optimization entity selects a connector to instantiate the required application by using in particular the connectivity parameters of the available connector.
- the determination of the at least one path comprises the selection of a new site capable of receiving a new connector whose connectivity characteristic is compatible with the virtual space of data.
- the deployment of new connectors, connected to the communications infrastructure according to the connectivity parameters required for the provision of the data transport service data, can be considered.
- the virtual data space is thus dynamically updated with new connectors that can host data and/or applications in charge of processing this data.
- the determination of the at least one path comprises the calculation for the at least one path of a parameter of transport quality of the data on the path.
- the determination step possibly makes it possible to identify several possible paths for the transport of the data, and in particular for the successive processing of these data on the paths.
- the selection of a path can be operated by a consumer of the data.
- the optimization entity can advantageously qualify each determined path with a transport quality parameter. For example, it may be a duration for routing and processing test data, this duration possibly resulting from a test carried out by the optimization entity on the various paths in order to calibrate them.
- the processing method further comprises the transmission to a data provider and/or to a data consumer of the at least one path.
- the selection of a path can be operated by a consumer of the data according to its own needs in terms of quality of transport of the data or else by another entity according to its objectives of confidentiality of the data transmitted for example.
- the method can therefore comprise a step of sending to an entity in charge of selecting the different paths and possibly information on the quality of transport, connectivity of the connectors used for transport, identification of the sites where the connectors are deployed or even information on software applying data processing.
- the processing method further comprises the configuration of the connectors of the path selected from among F at least one determined path.
- the optimization entity sets up the path.
- This instantiation can include the configuration of the circuit between the connectors, the deployment of new applications and/or new connectors. Knowing that the connectors are managed by the sites and more precisely by the operators of these sites, the instantiation can advantageously be carried out by requesting the various agents (brokers) of the storage sites (MEC) for the existing connectors or to be deployed, the agents software for the new applications required, as well as the entities in charge of the infrastructure to ensure the connectivity of the connectors to this infrastructure.
- This instantiation may also include the updating of data graphs including information on the new circuit set up and possibly usable for other services if the needs for quality of service and data confidentiality are compatible.
- the invention also relates to a device for processing a data transport service in a virtual data space deployed on a communications infrastructure, the virtual data space comprising a plurality of sites each comprising a communication server, also called connector, capable of hosting data or a data processing application, capable of communicating with the connector and comprising:

- FIG 3 presents a method for processing a data transport service according to a first embodiment of the invention
- FIG 4 presents an example of the structure of a data transport service processing device according to another embodiment of the invention.
- embodiments of the invention are presented in a communications infrastructure using routing means specific to a fixed network or to a mobile network.
- This infrastructure can be implemented to route communications data intended for fixed or mobile terminals and the invention can be intended to install virtualized functions used for the routing and/or processing of residential customer data or companies.
- FIG 1 presents a simplified view of a communications infrastructure comprising a virtual data space in which a method for processing a data transport service can be implemented.
- the communications infrastructure 1000 includes a virtual data space comprising a plurality of data storage spaces. Among these data spaces, we can distinguish data spaces belonging to companies 60, 70, 80, 90. These companies 60, 70, 80, 90 share for example data for the implementation of a service to from a customer not shown in [Fig 1]. Data spaces can also be stored in cloud spaces such as space 50. The data can also come from market places, that is to say space where it is possible to store data from different entities, this data can then be made available with other entities. These marketplaces allow entities to negotiate the acquisition of data.
- Entities can also deposit data in spaces at the periphery, such as space 10 of the communications infrastructure, for example in distributed data spaces of the MEC type (Multi Access Edge Computing as specified in https: //www.etsi.org/technologies/multi-access-edge-computing).
- a data space 30 can be specific to a loT (Internet of Things) service, or even to a corporate cloud 40 .
- the virtual data space which allows a third-party entity to access data from several data spaces via the virtual data space, is based on a security architecture so that a data provider retains control of its shared data and their processing and for the third-party entity to have a guarantee on the origin of the data collected.
- each 10, 20, 30, 40, 50, 60, 70, 80, 90 data space includes a 100, 200, 300, 400, 500, 600, 700, 800, 900 communication server, also called a connector, allowing data to be exchanged or made available to third-party entities (customer, other company, institution, etc.).
- the intervening virtual data space (EVD) must allow secure data exchange between the various actors involved in these exchanges.
- These connectors are used to collect the data and pour them, for example, into a storage space common to the members of the virtual data space, for example at the edge of the network. This allows the members of the virtual data space to carry out their analyzes locally without exporting their data but also to exchange them according to rules established with acquirers.
- the exchange rules make it possible to specify that a piece of data should not be exported but that the processing results on this data can be exported.
- the policies for distributing the data exchanged between the connectors, as well as the security rules (confidentiality in particular) are thus associated with the data in a file comprising the constraints for using the data identified C1, C2, C3 on [Eig 1].
- a data transport service may for example include the suite of connectors 100, 700, 800, 300 and this data transport may include processing applications included in some or all of the connectors of the following.
- the data of the connectors of the suite can be qualified with constraints of use of the data associated with each connector.
- FIG 2 a virtual EVD data space is shown.
- an Optim optimization entity in charge of implementing the data processing process of a transport service is deployed.
- This Optim entity can for example be implemented in an administration station of the virtual data EVD space.
- This Optim entity has a completely new and inventive role compared to existing IDSA architectures.
- the purpose of this entity is in particular to collect information from the operators of the communications infrastructure on which the virtual EVD data space is deployed. Indeed, the different data spaces are interconnected thanks to the resources of the communications infrastructure 1000, described for example in [Fig 1].
- This information on the connectivity of the data spaces to the communications infrastructure is advantageously used for the routing of the data in the virtual EVD data space. This information is used to optimize the routing of the data but also to optimize their processing knowing that applications deployed in data spaces are used to apply processing to this data during their routing.
- the virtual data space EVD also comprises entities specific to the management of MEC type data spaces.
- MEC Connec entity is to search for MEC type data spaces (MEC 1, MEC2, MEC3) that can actually host connectors of the virtual data EVD space.
- MEC servicing entity is managed by a connectivity service provider with connectors. The purpose of this entity is to control and retrieve the state of the connectivities used for the connectors. Information on the states of connections between connectors can be collected from entities such as a PCF (Policy and Charging Function), an NEF-type entity (Network Exposure Function), or an NWDAF-type entity. (in English Network Data Analytic Function) for a mobile network or a CLF type entity (in English Connectivity Location Function) or RACF (Resource Admission and Control Function) for a fixed network.
- PCF Policy and Charging Function
- NEF-type entity Network Exposure Function
- NWDAF-type entity in English Network Data Analytic Function
- CLF type entity in English Connectivity Location Function
- RACF Resource
- the virtual EVD data space also includes a Gest entity corresponding to a brokerage agent or a market place, ensuring the management of data offers and requests from various entities (client entities wishing to acquire data, suppliers of data).
- a Consum entity representing a data acquirer or consumer is included in this virtual data EVD space.
- the virtual data space also includes 3 storage spaces MEC1, MEC2, MEC3 whose identifiers and respective connectivity to the communications infrastructure are managed by the entities MEC connec and MEC served.
- the MEC1 space hosts, for example, data from the Propl and Prop2 entities, owners of their own data.
- These MEC storage spaces are interconnected using the links implemented by the operators of the communications infrastructure on which the virtual EVD data space is deployed. It should be noted that these MEC spaces can also host applications as is the case in [Fig 2] where the MEC1, MEC2 and MEC3 spaces respectively host the applications Appl, App2 and App3.
- These data spaces also include connectors in charge of ensuring the exchange of data between the different MEC spaces.
- Virtualized resources managed by pods can additionally be administered by an orchestrator.
- a Logic entity is also included in the virtual data EVD space and makes it possible to collect the characteristics of the applications as well as the types of connectors which must be used for the transport of data according for example to the constraints of the request for data or of constraints specific to the data itself.
- the Optim function can identify and locate the data as well as the location of the applications in charge of processing this data and required as part of a data transport offer.
- Data space connectivity information such as MEC1, MEC2, and MEC3 space connectivity is appended to object-specific information describing the required data.
- connectivity information such as endpoints of the object (connectivity identifier), information of the CLID type (in English Calling Id identifier RADIUS), a termination point of the MEC space, a location for example with GPS coordinates or even a postal code, or even the identity of the operator ensuring the supply of the connectivity of the connector to the communications infrastructure .
- the entity Optim can also obtain the data relating to the connectivity of the connectors of the spaces MEC1, MEC2, MEC3 directly from the spaces MEC1, MEC2 and MEC3.
- the Optim function can also obtain additional information from the operators providing the connectivity of MEC1, MEC2 and MEC3 to the communications infrastructure, including:
- the type of access used to connect an MEC1, MEC2 and MEC3 space to the communications infrastructure may be xDSL access, fiber access or radio access (Wi-Fi, 4G, 5G).
- the service profile of the MEC1, MEC2 and MEC3 space may be a maximum traffic volume, downlink/uplink transmission capacity, roaming capacities, identifiers and/or network slice characteristics (in English slice).
- the optimization entity Optim also obtains information on the applications installed in the spaces MEC1, MEC2 and MEC3 from the managers of these respective MECs.
- the Optim entity can supplement the information obtained on the applications (type of application, latency of the applications, software version of the applications, etc.) with information obtained from the Gest entity and/or from the Logic entity.
- the Optim entity processes the obtained data to identify the best path between connectors to route the data and apply processing to it. In particular, it identifies where to instantiate an application required for a data transport service, in particular in the case where no existing application in a MEC can perform the required processing or is not sufficiently well placed for the service.
- the entity can further identify where to place a new connector if no connector satisfies the required service.
- an end-to-end path is identified with possibly the processing applications required, the end-to-end path can be optionally selected or accepted by the requester and the Optim entity orchestrates the request with the various suppliers (managers of MEC1, MEC2, MEC3, managers of the communication infrastructure in charge of the connectivity of MEC1, MEC2, MEC3 to the infrastructure and the application suppliers if such needs are actually expressed.
- the owners Prop 1 and Prop 2 send a data offer to the Data Manager (or management agent) with context information associated with the data.
- this context information is for example described in a SOC (Separation of Concerns) format.
- the purpose of the Data Management Manager is to collect data offers and on the other hand to receive data transport service requests from the applicant who may be a professional client seeking to collect and possibly process data from from different data providers, for example for data correlation purposes or to conduct studies, typically of the Marketing type.
- This context information can for example include information on the location of the connectors hosting this data and the associated security rules, in accordance with the SOC description.
- the Data management manager transmits to the optimization Optim entity a request for deployment of a data transport service in a virtual data space instantiated on a communications infrastructure.
- This request includes the identifiers of the Prop 1 and Prop 2 owners as well as the connectivity identifiers of the MEC1 space and possibly of a connector of the MEC1 space, in which the data of these owners are stored.
- the request also includes the identifiers of the data consumers, for example of the Consom entity wishing to access the transported data, as well as the identifier of the MEC2 space and of a connector of the MEC2 space, where the data received for the Consum entity will be stored.
- the request further comprises the identifiers of the applications in charge of applying a processing to the data transported for the service considered.
- the request also possibly includes the context information associated with the data, for example in a SOC type graph, of the transport service.
- This context information includes, for example, the IP addresses of the connectors offering the data, the identifiers of the data, the rules associated with the policy for managing this data of the transport service, etc.).
- the Optim entity also obtains from the Gest entity identifiers of the connectivity providers associated with the connectivity identifiers of the MEC1 and MEC2 spaces. These identifiers are used in particular to join the connectors in the communications infrastructure.
- the Optim entity also obtains from the Gest entity a volume of data from the transport service, a frequency of transmission/reception of data by the connectors and by the applications in charge of the processing.
- the entity Optim obtains from the entity Logic data processing delays by applications applying processing to the data transported.
- the Optim entity can obtain from the Gest entity a list of applications already instantiated on the connectors during previously instantiated transport service implementations.
- the Optim entity obtains all the above information not from the Gest entity but directly from the Prop 1, Prop 2 and Consum entities.
- the connectivity service of the operators of the communications infrastructure is interrogated by the entity Optim to obtain additional information and in particular connectivity parameters of the connectors contributing to the data transport service as defined in the request received.
- These connectivity parameters can for example comprise a propagation time of a data packet between a connector and an access point of the communication infrastructure.
- the parameter may further comprise a propagation time between two connectors participating in the data transport service.
- the connectivity parameters can further comprise a type of technology (xDSL, Fibre, Wi-Fi, 4G, 5G%) used to connect a connector to the communications infrastructure.
- the type of technology can be dissociated between the type of transport technology (Ethernet, IP, LTE%) and the transport infrastructure (fiber, copper, Coaxial, Wi-Fi).
- a total bandwidth (connectivity subscription profile (guaranteed max uplink/downlink etc%)) associated with each connector or even a bandwidth available for transporting data from the transport service can also be obtained by the Optim entity .
- the connectivity parameters may further comprise a technology and/or a security protocol used for communications between a connector and an access point of the communication infrastructure.
- the Optim entity can also obtain from the Logic entity the software characteristics of the applications required for the data transport service. These software characteristics may include licenses associated with applications, storage space characteristics to be used to deploy applications, or application data processing times.
- the Optim entity determines at least one suite of connectors, hosting data and applications, to implement the transport service of data requested. This determination requires selecting the connectors offering connectivity, data routing and data processing characteristics that are the most suitable for the request received. In particular, these connectors are selected to obtain the best QoS and/or the least cost, for example in accordance with a parameter present in the SOC.
- This determination can also include the instantiation of an application in an existing connector to limit the traffic to be exchanged, for example by instantiating applications as close as possible to the connectors where transported data is stored. This instantiation requires identifying connectors to proximity of data sources, for example based on connector geolocation information transmitted by the Gest entity or the MEC Connec entity, or even the MECs themselves.
- the determination may also include the implementation of a new connector in the event that the existing connectors do not achieve the required QoS or if other connectors can improve the QoS.
- This implementation can be carried out by searching among the MEC connectivity providers, for example by requesting the MEC Connec entity, the MEC storage spaces compatible with the criteria in particular of security and confidentiality of the virtual data space.
- the Optim entity determines for the different paths, each composed of a series of connectors, a data transport quality parameter.
- the adaptation of the paths to the transport of the data as required is determined. This may involve, for example, calculating an end-to-end QoS and a cost associated with data transport by respecting the rules for using the data and taking into account the processing of applications on the path.
- These paths may include new connectors and may also include new instantiated applications, which requires assessing the QoS for routing and processing service data in the virtual data space.
- the determined paths and possibly the associated quality of service parameters are transmitted to the Consom entity and possibly to the Prop 1 and Prop 2 entities.
- This sending allows these entities to be able to select or to be able to eliminate one or more paths from the list.
- the Consom entity may choose a path with good QoS while an entity, such as Prop 1, may prohibit a path due to the presence of a connector or an application on the path that could compromise Datas.
- the Consum, Prop 1 and Prop 2 entities transmit their choice to the Optim entity in response to the request from the Optim entity.
- the Optim entity sets up the path(s) (s).
- This implementation consists of setting up connections between connectors providing and consuming data, instantiating applications for data processing if necessary, or even instantiating new connectors.
- the Optim entity can set up this path(s) independently or by requesting the Logic entities, MEC Connec as well as the operators in charge of the communications infrastructure.
- FIG 4 presents an example of the structure of a data transport service processing device according to another embodiment of the invention.
- the device 400 for processing a data transport service implements the method for processing a data transport service, various embodiments of which have just been described.
- Such a device 400 can be implemented in an application service management entity or else in a telecommunications network management entity, deployed based on virtualized functions or physical equipment.
- the device 400 comprises a processing unit 430, equipped for example with a microprocessor pP, and controlled by a computer program 410, stored in a memory 420 and implementing the determination method according to the invention.
- a computer program 410 stored in a memory 420 and implementing the determination method according to the invention.
- the code instructions of the computer program 410 are for example loaded into a RAM memory, before being executed by the processor of the processing unit 430.
- Such a device 400 comprises:
- a receiver 403 capable of receiving a Req request for deployment of the data transport service from a data management agent
- module 401 for obtaining capable of obtaining a connectivity parameter to the communication infrastructure of a connector of a site among the plurality, said connector contributing to the data transport service of the request received,
- a computer 402 capable of determining at least one data routing path in the virtual data space, the at least one path comprising an ordered sequence of connectors selected as a function of the connectivity parameter obtained.
- a customer of a logistics service wishes to follow the movement of his cargo of products in storage spaces (ports/warehouses) and transport services (container door, delivery truck) and the status of his storage (rental connected container (refrigerated example)).
- the customer thus needs to obtain information on the location of his goods from the various transport services, information on the condition of his products via the sensors in his container from the container rental services, and maintenance information in the storage spaces via the entities in charge of storage services.
- the customer can use applications to track the location of its cargo in real time as well as the status of its cargo.
- the processing may thus consist of identifying data, correlating data with each other, protecting data.
- a pharmaceutical company wants to analyze patient data for a specific disease and therefore needs to collect data from different hospitals in different countries without knowing the identity of the patients.
- Applications hosted in connectors near hospitals aggregate and analyze patient data, taking care, for example, to delete information relating to patient identities.
- MECs localized by country aggregate the patient data of a country, and the laboratory can thus aggregate the data of the different countries while respecting the local constraints of each country, requiring a specific treatment for each MEC, and minimizing the transfer of data to its connector via the appropriate use of communications infrastructures ensuring the connectivity of the MECs sites and the processing as close as possible to the MEC sites of the various countries. Only the data relevant to the laboratory are processed and transmitted, taking advantage of the specificities of the communication infrastructures.
- a geomarketing company wishes to analyze the behavior of a population of a so-called connected city (“smart city”). It can thus subscribe to access to data from transport services to find out how many transport lines are used, with catering services (to find out about residents' dining habits), to parking services (to find out about parking habits), to navigation assistance services (to know the habits and frequentation of the roads (road lights, navigation aid), to communication services (to know the communication information of the inhabitants), to entertainment services (to analyze the entertainment of the inhabitants) ...
- Each of these data providers may have already provided, via a virtual data space, for data processing requested by their own customers. These providers deploy applications in MECs near their data sources (sensors).
- processing implemented by an optimization entity, can identify the applications already in place to determine the data transport paths es that respond to different customers and optimize data transport.
- an application for example to compress data, will be preferred, taking into account the connectivity of the MEC spaces and the space where the application is implemented.
- the data from the different suppliers will thus be routed on a path taking into account the connectivity of the data storage spaces and the spaces where processing of this data can be carried out in an optimal way to meet the requirements in terms of quality of service and cost of the service.
