First, the term 'multi-tenancy' refers to the sharing of services by multi-tenancy based on virtualization technology and the same infrastructure in a computing environment.It runs a single instance of software to run multiple clients or businesses and organizations. Means to provide services to tenants. Examples of multi-tenancy environments include SaaS Platform, cloud service systems, or cloud service centers.
'Multi-Tenant' means a plurality of tenants, and one tenant is a group using a service, for example, one enterprise. Therefore, one tenant includes a plurality of users.
A service provider is a provider of cloud computing services such as SaaS, PaaS, and IaaS.
Cloud Services Brokerage is a form of service provider that acts as an intermediary in cloud computing. It is an enterprise model that adds value to one or more cloud services on behalf of consumers who use the service. Typical technologies that enable Cloud Services Brokerage include governance, integration, management, and development community management.
There are several types of Cloud Services Brokerage, for example Intermediation Broker, Service Aggregation, and Cloud Service Arbitrage. Intermediation Broker is a model that enhances the value of an existing service by supplementing identity, access, and security to an existing service. Service Aggregation is a model that provides different cloud services to customers by making them new services through Data Integration, Data Model, Federation, etc. of Service Aggregation. Cloud Service Arbitrage is similar to Service Aggregation, but it is a model that gives you the opportunity and flexibility to choose a service in collecting services.
Wide Area Network Accelerator is a solution that speeds up applications on a wide area network (WAN). Installing a WAN accelerator between the end-to-end ends up compressing and transferring data, improving the responsiveness by increasing the transmission efficiency of caching, quality of service (QoS), and Transmission Control Protocol / Internet Protocol (TCP / IP). Web Accelerator compresses and transmits files such as web protocol home page, web developed groupware, and Korean and Microsoft document files, while WAN accelerator supports improved efficiency for both Web protocol and TCP / IP. do.

Referring to FIG. 4, the message flow until the WAN acceleration period is made by requesting the use of a cloud service may be largely divided into six steps.
One. Request message sending step ( REQUEST )
The first tenant may transmit a request message for requesting the use of the cloud service to the cloud service broker (hereinafter referred to as "broker"). The first tenant is a source IP, a source port, a destination IP, and a destination port, respectively, the first tenant's IP, the first tenant's port, the broker's IP, and the cloud. A request message including the representative port of the PAT allocated to the service can be generated and transmitted to the broker. The destination IP and the destination port may be an IP and a port previously provided to the first tenant by the broker based on a cloud service use contract between the first tenant and the broker. That is, the destination IP is the broker's IP, and the destination port is a representative port for each service determined by the broker to distinguish the cloud service to be used in the first tenant.
2. Processing stage
The broker is an intermediary for connecting the first tenant and the service provider, and may manage tenant IPs, service provider IPs, PATs, cloud service contract information, and mapping information of subports allocated to the first tenant. .
In the broker of FIG. 4, a representative port and sub ports of PAT allocated to each cloud service are stored in the 'PAT table', and the ID and IP of tenants contracted to use the cloud service are stored in the 'Tenant IP table'. . In addition, the IP of each service provider is stored in the 'Service Provider IP table', and the representative port of the cloud service and the cloud service contracted by each tenant is stored in the 'Contract Table', and the 'T-SP Port, IP mapping table by In Process', the
The broker compares the source IP and destination port of the request message received from the first tenant with the contract details and one of the above-described tables (or one of the network information of [Table 1] to [Table 5]), The subports available to the first tenant may be mapped and stored using the PAT allocated to the cloud service. In addition, the broker may determine whether to apply the acceleration service based on the contents of the contract concluded with the first tenant.
3. Request message sending step ( REQUEST )
The broker may generate and send a request message to be sent to the service provider by two-step processing. The broker generates a request message including the source IP, the source port, the destination IP, and the destination port, respectively, the broker's IP, the subport assigned to the first tenant for the cloud service, the service provider's IP, and the port assigned to the service provider. can do.
4. Send response message step ( RESPONSE )
The service provider receiving the request message may determine whether to provide the accelerated service based on the information described in the request message and the contents of the contract. The service provider may generate a response message and transmit the response message to the broker according to the determination result. If it is determined to provide the accelerated service, the service provider is a source IP, source port, destination IP and destination port, respectively, the service provider's IP, the service provider's port, the broker's IP, and the sub tenant assigned to the first tenant for the cloud service. You can create a response message that includes a port.
5. Processing stage
The broker receiving the response message checks the source IP and source port of the response message to determine that the response message has been received from the service provider, and generates the response message using the representative port mapped to the first tenant in the PAT table. have. The broker is a source IP, a source port, a destination IP, and a destination port, respectively, the broker's IP, the representative port stored in the first tenant (that is, the representative port assigned to the cloud service), the first tenant's IP, and the first tenant's port. Can generate a response message including a. In this case, the broker may determine and execute whether to generate an acceleration section between the first tenant and the broker.
6. Send response message step ( RESPONSE )
The broker sends a response message to the first tenant, which generates one of the WAN acceleration section and the bypass section between the first tenant and the broker, and the WAN acceleration section and the bypass section between the broker and the service provider. One of can be generated.
FIG. 5 is a diagram illustrating an example of a system to which a WAN acceleration section is applied by a cloud service broker according to an exemplary embodiment of the inventive concept.
Referring to FIG. 5, according to an exemplary embodiment of the inventive concept, the WAN acceleration interval is applied to the end-to-end between the tenant and the cloud service broker, or the end-to-end between the cloud service broker and the service provider. It can be seen that it can be applied to or applied to both end-to-end.
The first service provider provides a cloud service called BI, and the second service provider provides a cloud service called groupware. If the first tenant has contracted to use BI service and cloud service called groupware through the cloud service broker, the first tenant applies WAN acceleration period to both end-to-end for BI service and the groupware service. We can contract not to apply WAN acceleration section to both end-to-end. Accordingly, a WAN acceleration section is generated at two end-to-ends between the first tenant-cloud service broker and the first service provider by the process as shown in FIG. 5, and the first tenant-cloud service broker-second service provider. It can be seen that a bypass section is generated between two end-to-ends.
If the third tenant contracts not to apply WAN acceleration intervals for all cloud services, it communicates at the normal default baud rate at both end-to-ends between the third tenant-cloud service broker-first / second service provider. can do. Alternatively, when the first service provider provides the WAN acceleration service free of charge, a bypass section is generated at the end-to-end between the third tenant and the cloud service, and the end-between the cloud service broker and the first service provider is created. In the to-end, a WAN acceleration section may be generated.
The cloud service broker selectively generates a WAN acceleration section based on the contract contents of each of two end-to-ends between tenants and service providers, and creates and manages connection information (or network information) for the tenant and service providers. For example, service usage using WAN acceleration can be presented as the basis for billing and SLA.
In the present invention, when the cloud service is provided in various forms in various environments, the WAN acceleration service can be used flexibly and efficiently.
6 is a flowchart illustrating an acceleration service support and management method of a cloud service broker operating on a multi-tenancy basis according to an exemplary embodiment of the present invention.
The tenant, service provider, and cloud service broker for the accelerated service support and management method of FIG. 6 may be the
Referring to FIG. 6, when a contract for providing a cloud service between a service provider and a cloud service broker (hereinafter, referred to as a 'broker') is concluded (S600), the broker represents a representative port of the PAT for the cloud service that the service provider intends to provide. And sub ports may be allocated (S605).
The broker may store the network information of the service provider and the contract details concluded at step S600 (S610). The network information of the service provider includes the PAT of the cloud service allocated in step S605, representative ports and sub ports of the PAT, IP and port of the service provider, and may be stored as shown in [Table 2].
In addition, the broker may update the PAT allocated in the step S605 to the PAT table as shown in [Table 2], and record the network information related to the contract of the service provider as shown in [Table 1] (S615).
Thereafter, if a contract for using cloud services between the tenant and the broker is concluded (S620), the broker may provide the tenant with a representative port of the cloud service allocated in step S805 (S625).
The broker may store the contents of the contract with the tenant concluded in step S620 through the cloud service intermediation platform and store network information related to the tenant as shown in [Table 3] (S630).
When a request message for using the cloud service contracted for use in step S620 is received from the tenant (S635), the broker may analyze the received request message and generate the request message based on the analysis result (S635). S640). In step S640, the broker may allocate one of the subports of the PAT allocated to the cloud service to the tenant, and generate a request message with reference to the information in [Table 6]. Operation S640 to operation S670 to be described later will be described in detail with reference to FIGS. 7 and 8.
The broker transmits the request message generated in step S640 to the service provider (S645), and receives a response message from the service provider (S650).
Based on the information described in the response message received in step S650, one of the second acceleration section and the second basic section may be generated between the broker and the service provider (S655).
The broker generates a response message with reference to the information described in the response message received in step S650 and the information in [Table 6] (S660), and transmits the generated response message to the tenant (S665).
When the tenant receives the response message in step S665, one of the first acceleration section and the first basic section may be generated between the broker and the tenant (S670).
The broker receives a cloud service for mediation from the service provider through one of the second acceleration period and the second basic period generated in step S655 (S675).
During operation S675, the broker may store the usage information transmitted and received through one of the second acceleration period and the second basic period by mapping the tenant ID or the subport assigned to the tenant (S680).
In addition, the broker transmits the cloud service provided from step S675 to the tenant through one of the first acceleration section and the first basic section (S685), and allocates usage information of the data transmitted in step S685 to the tenant's ID or tenant. The mapped subport can be stored (S690).
The broker may set a charge to be applied to at least one of the tenant and the service provider based on the usage information stored in steps S680 and S690 and the charge policy managed by the broker, and report the result to the tenant or the service provider ( S695).
7 and 8 are flowcharts for describing in more detail the steps S640 to S670 of FIG. 6.
The process described with reference to FIGS. 7 and 8 is an example of steps S640 to S670, and steps S640 to S670 are not limited thereto.
First, referring to FIG. 7, the broker may check the source IP, the source port, the destination IP, and the destination port of the request message received in step S635 (S700). The broker may analyze the source IP, the source port, the destination IP and the destination port identified in step S700, and the contract contents concluded in step S620 with the tenant to confirm whether the tenant has contracted the use of the acceleration service for the cloud service.
To this end, the broker may check whether the same tenant IP as the source IP identified in step S700 exists in the table of [Table 3] (S705).
If the same tenant IP as the source IP identified in
If it is confirmed that the tenant has contracted to use the acceleration service between the tenant and the broker (S710-Y), the broker may check whether the tenant has contracted the use of the acceleration service between the broker and the service provider (S715). In steps S710 and S715, the broker confirms whether the contract for the use of the acceleration service is contracted from the contract contents mapped to the ID of the tenant, or the representative mapped to the representative port or PAT when the acceleration service contract is made in the table as shown in [Table 3]. If there is a port, you can confirm that you have contracted to use the acceleration service.
If the tenant is found to have contracted to use the accelerated service between the broker and the service provider (S715-Y), the broker assigns an available one subport to the tenant among the plurality of subports allocated to the PAT of the cloud service. The allocated subports can be stored in a table as shown in [Table 4] (S720).
The broker may generate a request message using the sub-port allocated in step S720 as the source port with reference to [Table 6] and transmit the generated request message to the service provider (S725).
The service provider receiving the request message checks the source port included in the request message, and if the same subport as the identified source port matches one of the subports allocated from the broker when contracting to provide the cloud service, the cloud A response message indicating that the service can be provided as an acceleration service can be generated with reference to [Table 6].
The broker may receive and analyze a response message from the service provider (S730). In step S730, if the destination port of the received response message is the same as the source port described in the request message (that is, one of a plurality of sub-ports assigned to the PAT of the cloud service), the broker performs a second acceleration period with the service provider. Can be generated (S735).
The broker may generate a response message in which the source port is a representative port of the cloud service (that is, a destination port of the request message or a representative port of the PAT) with reference to [Table 6], and then transmits the response message to the tenant (S740).
As a result, the tenant and the broker generate a first acceleration section (S745).
On the other hand, if the tenant is determined to not use the accelerated service between the broker and the service provider (S715-N), the broker allocates a port to the tenant other than the multiple subports allocated to the PAT of the cloud service, and allocates the tenant. The stored ports can be stored in a table as shown in [Table 5] (S750).
The broker may generate a request message having the port assigned as the source port in step S750 with reference to [Table 6] and transmit the generated request message to the service provider (S755).
The service provider receiving the request message determines that the cloud service is not provided as an acceleration service if the source port included in the request message is different from the subports allocated by the broker when contracting to provide the cloud service, and the response message is determined. Can be generated with reference to [Table 6]. At this time, the destination port of the response message is the same as the source port of the request message received in step S755.
The broker may receive and analyze the response message from the service provider (S760).
In step S760, if the destination port of the received response message is the same as the source port described in the request message, the broker may generate a second basic section with the service provider (S765).
The broker may generate a response message in which the source port is a representative port of the cloud service (ie, a destination port of the request message or a representative port of the PAT) and transmit the response message to the tenant (S770). In step S770, since the broker confirms that the tenant has contracted to use the acceleration service between the tenant and the broker in step S710, the broker generates a response message in which the source port is a representative port of the cloud service.
As a result, the tenant and the broker generate a first acceleration section (S775).
Meanwhile, referring to FIG. 8, when it is confirmed that the tenant has contracted not to use the acceleration service between the tenant and the broker (S710-N), the broker may check whether the tenant has contracted the use of the acceleration service between the broker and the service provider. (S805).
If the tenant is found to have contracted to use the accelerated service between the broker and the service provider (S805-Y), the broker assigns an available one subport to the tenant among the plurality of subports allocated to the PAT of the cloud service. The allocated subports can be stored in a table as shown in [Table 4] (S810).
The broker may generate a request message using the sub-port allocated as the source port in step S810, and transmit the generated request message to the service provider (S815).
The broker may receive and analyze a response message from the service provider (S820). In step S820, if the destination port of the received response message is the same as the source port described in the request message, the broker may generate a second acceleration section with the service provider (S825).
The broker may generate a response message in which the source port is a representative port of the cloud service (that is, a destination port of the request message or a representative port of the PAT) and transmit the response message to the tenant (S830).
As a result, the tenant and the broker generate a first acceleration section (S835). This is because, in step S710, the tenant has confirmed that the tenant and the broker do not use the acceleration service.
On the other hand, if the tenant is confirmed not to use the accelerated service between the broker and the service provider (S805-N), the broker allocates a port other than the plurality of subports allocated to the PAT of the cloud service to the tenant, and allocates the tenant. The stored ports can be stored in a table as shown in [Table 5] (S840).
The broker may generate a request message using the assigned port as the source port in step S840 and transmit the request message to the service provider (S845).
The broker may receive and analyze a response message from the service provider (S850).
In step S850, if the destination port of the received response message is the same as the source port described in the request message, the broker may create a second basic section with the service provider (S855).
The broker may generate a response message in which the source port is a representative port of the cloud service and transmit the response message to the tenant (S860).
As a result, the tenant and the broker generate a first basic section (S865). This is because, in step S710, the tenant is confirmed not to use the acceleration service between the tenant and the broker.
As described above, the present invention has been described by way of limited embodiments and drawings, but the present invention is not limited to the above embodiments, and those skilled in the art to which the present invention pertains various modifications and variations from such descriptions.
