Traditional virtualization-based services provided servers and storage on-demand to users like the Amazon cloud. Since then, cloud infrastructure virtualization-based services have been provided to provide Network Function Virtualization (NFV) services that virtualize network functions.

Referring to FIG. 1, the structure of a conventional virtualization-based service is separately constructed for a communication technology service 111 and an information technology service 131 in the cloud infrastructures 110 and 130.

That is, in order to additionally provide another service in the single CT service 111 or the IT service 131, two cloud infrastructures (hereinafter, referred to as " OpenStack Virtual Infrastructure Manager " (110, 130). For reference, the open-stack technology is an open-source cloud technology that provides the scalability and modularity of virtualized computing services, storage services and Software Defined Network (SDN) services in the provision of infrastructure services. Thus, a service can be provided that matches the unique characteristics of the required cloud infrastructure.

Here, building two cloud infrastructures 110 and 130 for the CT and IT services 111 and 131 has a problem in that time and cost increase. Of course, the independent cloud is operated by two physical systems, which are structured in the form of a silo in the absence of communication due to closure, and have an inefficient structure requiring interfacing, communication, and processing for interoperation between these physical systems There is a problem.

In addition, compute nodes (eg, servers) providing services in a cloud system are configured to have the same performance, which has the difficulty of administrating each physically separated node. In addition, it is inefficient for each compute node to configure the HW and SW performance equally without considering the service characteristics of the subscriber. Therefore, allocating the cloud infrastructure with performance exceeding the subscriber's service performance is a waste of resources have.

5 is a schematic diagram of a cloud constructed for an ICT service in a distributed environment based on the system 200 layers 210, 230, and 250 of FIG.

The system 200 comprises a central cloud 510 in a distributed environment and a plurality of edge clouds 530 and 550 corresponding to regional offices. The central cloud 510 constructs and distributes services to the edge clouds 530 and 550 according to subscription of the subscriber. In FIG. 5, the left edge cloud 530 (hereinafter, referred to as a first edge cloud) is constructed according to a request of the first subscriber, and the right edge cloud 550 (hereinafter referred to as a second edge cloud) The CT service is established according to the request of the second subscriber.

Since the present invention provides the cloud orchestrator 225 for the IT service in the system 200, the type-specific service of CT, IT, or ICT according to the on-demand of the subscriber is divided into the physically independent first edge cloud 530 and the second edge And can be optimally built into the cloud 550. [ Also, in the ICT service, the VIM 237 can manage the interworking of the NFV compute node 531 and the IT compute node 533 integrally.

The central cloud 510 comprises an E2E infrastructure orchestrator 211, an NFV orchestrator 223, an SDN orchestrator 221, a cloud orchestrator 225 and an NFV manager 235.

The first edge cloud 530 includes an SDN controller 231, a VIM 237, an NFV compute node 531, an IT compute node 533, and a switch 535.

The NFV compute node 531 is configured to provide a CT service. Also, the IT compute node 533 is configured to provide an IT service. The NFV compute node 533 has a plurality of VMs built therein, and each of the established VMs includes a router, a firewall, a network address translator (NAT), a virtual private network (VPN) controller .

Here, assuming that the first subscriber connected to the first edge cloud 530 transmits data, the transmission data is transmitted to the NFV compute nodes (&quot; 531, the router VM, the firewall VM, the network address translation VM, and the virtual network VM. If the transmission data is data of the IT service, it is processed as an IT service through the server VM of the IT compute node 533. If the transmission data is data for external communication other than the IT service, the data is transmitted to the destination via the core and the Internet via the switch 535.

For reference, the CT service is provided with a router VM configured as a basic pack, a firewall VM, and a network address translation VM. In the IT service, a virtual server and virtual storage of the server VM are provided.

On the other hand, if it is assumed that the second subscriber connected to the second edge cloud 550 transmits data, the transmission data is transmitted to the switch, the core, and the Internet via the VM of the second edge cloud 550 based on the CT service. Lt; / RTI &gt;

6 is a schematic flow diagram of distributing an ICT service according to an embodiment of the present invention.

The subscriber inputs subscriber information including a company name and address, requests subscription according to the service type of CT, IT and ICT, and the request of the subscriber is transmitted to the E2E infrastructure orchestrator 211 (S601). In the CT service, a basic pack (eg virtual router + virtual firewall + virtual NAT) is provided, and a data pack (eg virtual server + virtual storage) is provided in the IT service. The E2E infrastructure orchestrator 211 classifies the network service / IT service / network connection type according to the service request of the subscriber and selects the orchestrators 221, 223, and 225 to be processed (S602). CT service requires network service + network connection, and IT service requires ITS connection + network connection.

For the network connection, the E2E infrastructure orchestrator 211 requests the network usable resources of the edge by the SDN orchestrator 221 (S611). In the case of the ICT service, the network resource is requested by the edge cloud 533, and the network resource such as the internal and external VLAN, IP information and the like is generated by the request.

For the network service, the E2E infrastructure orchestrator 211 provides the network information to the NFV orchestrator 223 to request the generation of the VNF 631 for the network service (S613). In accordance with the generation request, installation of NSD (Network Service Descriptor) on-boarding for CT service, configuration of virtual network, allocation of computing resources, generation and setting of VNF 631, and the like are processed.

For the IT service, the E2E infrastructure orchestrator 211 provides the network information to the cloud orchestrator 225 to request the creation of the VNF 631 for the IT service (S615). In accordance with the generation request, the configuration of the virtual network for the IT service, the allocation of the computing resource, and the creation and setting of the VNF 631 are processed.

The NFV orchestrator 223 and the cloud orchestrator 225 request the VIM 237 to construct a server according to the generation of the VNF 631 and the VM 633, respectively, in order to generate the VNF 631 (S621) . The VIM 237 requests the compute node 630 to create the VNF 631 and the VM 633 through the compute component 613 (e.g., Nova) of the open stack (S623).

In response to the request, the compute node 630 generates the VNF 631 and the VM 633. Of course, the compute node 630 includes an NFV compute node 531 for the CT service and an IT compute node 533 for the IT service.

When the VNF 631 and the VM 633 are generated, a connection of the VNF 631 and the VM 633 is requested through the network component 611 (e.g., Neutron) (S631). In response to the request, the SDN controller 231 receives the compute host information and the network information of the VM 635 through the L2 plug-in 611 (S633). The SDN controller 231 establishes a virtual network of the cloud by connecting the virtual switch 637 and the hardware switch 651 (S635). The SDN controller 231 transfers the constructed network information to the SDN orchestrator 611 and updates it (S637). The SDN orchestrator 611 initiates resource management based on the received network information resources.

Thereafter, the NFV orchestrator 211 sets a service request to the VNF 633 through the VNF manager 235 (S641). An environment (e.g., a flow rule) of the VNF 633 matching the service of the subscriber is set. The NFV orchestrator 223 and the cloud orchestrator 225 report that the construction and distribution of the service is completed with the E2E infrastructure orchestrator 211 (S643).

FIG. 7 is a table illustrating the types of computing zones and groups for a cloud that are optimized for service performance of a subscriber in accordance with another embodiment of the present invention.

The cloud according to the present invention classifies the compute nodes of the cloud into zones and groups according to the subscription type and performance of the service. The zone divides the compute nodes 630 into an NFV zone 710 for CT service (network service) and an application zone 730 for IT service based on the subscription type of the logical service.

In addition, the following are applied differently to provide virtualization rates in resource-optimized form:

- NFV zone: 1: 1 ratio of CPU and memory overcommit

- Application zone: 1: 16 ratio of CPU and memory overcommit

That is, in the application zone 730, 16 memories can be divided and allocated to the subscribers in units of 1/16.

The group separates the compute nodes in each zone logically into dedicated hardware class, high performance, and basic group according to function / characteristic according to workload. The higher the hardware level, the higher the load, the better the performance, and the lower the base, the lower the load, is suitable for low performance.

In addition, different performance acceleration techniques are applied to segmented compute nodes for each group. For example, hardware-accelerated devices such as GPU (Graphic Processing Unit) and SSD (Solid State Drive) are used for dedicated hardware-level groups, and high-performance network devices such as PCI-PT . Cloud base technologies can be applied to base groups without applying any acceleration techniques.

Cloud management using the zone and group has the following advantages. Once the service is determined by subscriber's subscription, the plan, design and installation to distribute the subscriber to the subscriber begins. At this time, it is required to configure a compute node according to the service type and performance of the subscriber. Here, even if the physical locations of the compute nodes of the same subscriber are separated, each computer node is integrated in the NFV zone 710 and the application zone 730, which are separated according to the services, so that the convenience of the manager's infrastructure resource management is ensured. In addition, since the group management can repeatedly construct infrastructure resources with performance optimized for each subscriber, it is assured that the construction time and the construction cost are reduced due to the optimized resource input.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It goes without saying that various modifications and variations are possible within the scope of equivalence of the scope.
