Description

  The present invention relates to a communication apparatus and a communication network resource control method.

  2. Description of the Related Art Conventionally, it is known that a communication carrier such as an ISP (Internet Service Provider) performs network operation management by sharing one resource of a communication network among a plurality of user terminals. Examples of such network operation management include SaaS (Software as a Service), PaaS (Platform as a Service), or MVNO (Mobile Virtual Network Operator).

  In addition, when a telecommunications carrier provides a communication service to a user terminal, there is a method in which a guaranteed bandwidth of the communication service is determined in advance and a fixed bandwidth is secured by VLAN-VPN (Virtual Local Area Network-Virtual Private Network). Are known. In addition, the communication carrier may secure a fixed bandwidth by RSVP-TE (Resource reSerVation Protocol-Traffic Engineering) or the like. In addition, when a user terminal uses a communication network, a telecommunications carrier has a method for allocating virtual resources of a communication network to user terminals, such as a method of securing a communication band according to the use status of resources of the communication network. It may be adopted.

  However, the prior art does not take into consideration promptly responding to requests such as addition, change or deletion of user terminal resources when sharing communication network resources among a plurality of user terminals.

  In other words, when there is a request from a new user terminal to use a communication network, the conventional technology redesigns the line design considering the communication path and communication band, and each time a virtual resource is assigned to all communication devices arranged on the network. Since this is reset, control costs are required. Similarly, when there is a request for addition, change, or deletion of a resource from the user terminal, control costs are incurred because virtual resources are reset in all communication devices arranged on the network each time. In addition, since the virtual resource allocated to each user terminal is static based on the network design, it may be necessary to reset the communication device in the event of construction or failure of the communication network.

  In addition, the prior art is a method in which the minimum bandwidth of the communication network is secured in advance, and the bandwidth is dynamically expanded by checking the available bandwidth when the communication network is used. There is a case.

  Further, in the conventional technology, for example, when providing resources such as SaaS and PaaS as a service, the lead time from service application to service opening may be long. In addition, since the conventional technology requires switching to a new network in order to respond to a user's bandwidth and an application for improving serviceability, there may be a temporary service interruption. Therefore, in recent years, there is a growing need for users themselves to perform bandwidth expansion and service expansion for each service on demand.

  The disclosed technology has been made in view of the above, and can quickly respond to requests such as addition, change, or deletion of user terminal resources when a communication network resource is shared by a plurality of user terminals. An object of the present invention is to provide a communication device and a communication network resource control method.

  In one aspect, a communication device disclosed in the present application includes a reception unit that receives a request signal including addition, change, or deletion of the resource from a plurality of user terminals that share the resource of the communication network. Further, the communication device disclosed in the present application, when the request signal is received by the receiving unit, the source of the request signal from a plurality of virtual resources provided by dividing the communication network resource according to a preset division criterion A resource display control unit to be displayed on the user terminal. The resource display control unit extracts and requests at least one of a virtual resource that is being used by the user terminal that is the source of the request signal and a virtual resource that is not being used by any of the plurality of user terminals from among the plurality of virtual resources. It is displayed on the user terminal of the signal transmission source. Moreover, the communication apparatus disclosed in the present application includes a resource control unit that executes addition, change, or deletion of a resource to be allocated to a user terminal that is a transmission source of a request signal. The resource control unit allocates the request signal transmission source user terminal based on the virtual resource selected by the request signal transmission source user terminal from among the virtual resources displayed on the request signal transmission source user terminal. Add, change, or delete resources.

  The provider access unit 102 transmits and receives communication signals to and from the system terminal 50 used by the end user (tenant) via the communication bus 52. The resource display control unit 104 performs control to extract a virtual resource corresponding to a request to add, change, or delete a communication network resource transmitted from the system terminal 50 and display the virtual resource on the system terminal 50. For example, if the request from the system terminal 50 is to add a resource, the resource control unit 106 merges the virtual resource currently used by the system terminal 50 with the newly added virtual resource. The NW control unit 108 receives the merge result executed by the resource control unit 106, performs various settings for the communication device, and transmits the packet transmitted from the system terminal 50 to the communication network 116. Data transmission / reception among the provider access unit 102, the resource display control unit 104, the resource control unit 106, the NW control unit 108, the virtual resource inventory management table 110, and the virtual resource inventory payout table 112 is performed via the communication bus 114. Details of the resource display control unit 104 and the resource control unit 106 will be described later.

  FIG. 2 is a diagram illustrating the overall configuration of the communication network. As shown in FIG. 2, the system terminals 50-1 to 50-3 and the system terminals 50-4 to 50-6 are connected by a plurality of lines 120, 122, and 124. A plurality of communication devices 126-1 to 126-10 are provided on the communication paths of the lines 120, 122, and 124. In this embodiment, an equal communication service is not provided to the system terminals 50-1 to 50-6, but for example, the communication service provided according to an individual contract with the system terminals 50-1 to 50-6 is different. Can be provided. In this embodiment, for example, the system terminals 50-3 and 50-6 are terminals used by general users, the system terminals 50-2 and 50-5 are terminals used by member users, and the system terminals 50-1 , 50-4 are terminals used by premium users. In this case, the communication service provided in the order of the system terminals 50-3 and 50-6, the system terminals 50-2 and 50-5, and the system terminals 50-1 and 50-4 can be improved.

  In this embodiment, the communication band can be divided into a plurality of virtual resources for each of the lines 120, 122, and 124. For example, when the physical communication bands of the lines 120, 122, and 124 are all 1 Gbps (Gigabit per second), the line 120 can prepare 10 lines of 100 Mbps (Megabit per second) in advance. For example, 100 lines of 10 Mbps can be prepared in advance for the line 122 and 1000 lines of 1 Mbps can be prepared for the line 124 in advance.

  FIG. 3 is a diagram illustrating an example of a virtual resource inventory management table. As illustrated in FIG. 3, the virtual resource inventory management table 110 stores a plurality of virtual resources provided by dividing a communication network resource according to a preset division criterion. More specifically, the virtual resource inventory management table 110 stores a band, the number of hops, and a usage status corresponding to a resource ID (IDdentification) for each of a plurality of virtual resources. The usage status indicates whether or not the virtual resource is used by the system terminal. As an example, a virtual resource with a resource ID of “100” has a bandwidth of “100 Mbps” and a hop count of “4” and is currently used by any of the system terminals 50-1 to 50-6. It shows that. On the other hand, the virtual resource with the resource ID “300” has a bandwidth of “10 Mbps” and a hop count of “5” and is not currently used by any of the system terminals 50-1 to 50-6, that is, a free virtual resource. Indicates a resource. Note that the virtual resource inventory management table 110 is not limited to the example illustrated in FIG. 3, and stores a plurality of virtual resources divided in consideration of the communication bandwidth, the number of hops of the route, free time information, resource usage status, and the like. be able to.

  FIG. 4 is a diagram illustrating an example of a virtual resource inventory payout table. The virtual resource stock payout table 112 stores a stock payout status indicating which virtual resource is used by which system terminal among the plurality of virtual resources stored in the virtual resource stock management table 110. The virtual resource inventory payout table 112 corresponds to the service ID for identifying the communication service provided to the system terminals 50-1 to 50-6, the user ID using the service, and the service ID used by the service The resource ID of the virtual resource being stored is stored. For example, a communication service with a service ID “100” is used by a user (system terminal) with a user ID “100”, and the system terminal uses a virtual resource with a resource ID “100”. Indicates that it is being used.

  Next, returning to FIG. 1, processing contents of the communication apparatus of this embodiment will be described. First, as indicated by the solid line arrow in FIG. 1, when the provider access unit 102 receives a request signal for displaying a communication network status from the system terminal 50, the provider access unit 102 transfers the request signal together with the user ID to the resource display control unit 104. The communication network 116 status display request signal transmitted from the system terminal 50 may be, for example, a communication network resource addition, change, or deletion request signal.

  Subsequently, the resource display control unit 104 displays the user information read from the virtual resource inventory payout table 112 and the virtual resource availability read from the virtual resource inventory management table 110 on the system terminal 50. For example, when the request signal from the system terminal 50 is an addition of a resource, the resource display control unit 104 extracts a free virtual resource from the virtual resource inventory management table 110 and sends the extracted free virtual resource to the system terminal 50. Can be displayed. Further, for example, when the request signal from the system terminal 50 is deletion of the resource, the resource display control unit 104 extracts the virtual resource being used by the system terminal 50 from the virtual resource inventory payout table 112, and the system terminal 50 Can be displayed. In addition, for example, when the request signal from the system terminal 50 is a resource change, the resource display control unit 104 extracts a free virtual resource and a virtual resource that is being used by the system terminal 50 to the system terminal 50. Can be displayed.

  Further, as indicated by a broken line arrow in FIG. 1, the end user who has grasped the communication network status at the system terminal 50 selects a desired virtual resource and issues a request for securing the resource to the provider access unit 102. Then, the provider access unit 102 transfers this request to the resource control unit 106 together with the service ID, the user ID, and the use request resource ID. The resource control unit 106 extracts, for example, the virtual resource currently used by the end user for the target service from the virtual resource inventory payout table 112, and merges it with the resource requested to be used. The resource control unit 106 notifies the NW control unit 108 of the merge result, and the NW control unit 108 performs setting to the communication device. Hereinafter, the virtual resource allocation control of the communication apparatus according to the present embodiment will be described using a more specific example.

  FIG. 5 is a diagram for explaining an example of virtual resource allocation control. FIG. 5 illustrates the virtual resource inventory management table 110 and the virtual resource inventory payout table 112 before and after the change when providing a communication service to a new user. First, when the provider access unit 102 receives a request signal for providing a communication service from a new user, the resource display control unit 104 refers to the virtual resource inventory management table 110 to extract a free virtual resource and Display on the system terminal. More specifically, the resource display control unit 104 is not currently used by any of the system terminals 50-1 to 50-6, and the “usage status” in the virtual resource inventory management table 110 is empty. Extract resources and display them on the system terminal that requested the service. Here, it is assumed that virtual resources with resource IDs “300” and “600” surrounded by broken lines 150 and 152 in the virtual resource inventory management table 110 are extracted and displayed on the system terminal that is the service request source.

  Subsequently, when the virtual resource having the resource ID “300” or “600” is selected by the system terminal that is the service request source, the resource control unit 106 selects the virtual resource having the resource ID “300” or “600”. Assigned to the system terminal that requested the service. Here, an example is shown in which the user ID of the system terminal that is the service request source is “400” and a service with a new service ID “500” is provided. In this case, the resource control unit 106 is using the virtual resource usage status of the resource IDs “300” and “600” in the virtual resource inventory management table 110 as indicated by the broken lines 151 and 153 in the virtual resource inventory management table 110. Set to. Further, as indicated by a broken line 154 in the virtual resource inventory payout table 112, the resource control unit 106 sets the service ID “500”, the user ID “400”, and the resource ID “300” in the virtual resource stock payout table 112. ”And“ 600 ”are added. As described above, when providing a communication service to a new user, the communication service can be quickly opened simply by assigning a virtual resource (unit resource) desired by the new user from the virtual resource inventory management table 110. it can.

  FIG. 6 is a diagram for explaining an example of virtual resource allocation control. FIG. 6 illustrates the virtual resource inventory management table 110 when dynamically changing communication network resources. As shown in FIG. 6, in this example, the virtual resource inventory management table 110 stores free time information in association with resource IDs. For example, it is assumed that a user A is currently contracting for a service with a communication bandwidth of 100 Mbps. This user A, for example, conducts a TV (TeleVision) conference on Mondays from 10:00 to 12:00, and uses only the MAX communication band only during the time when the video conference is performed. Suppose you only want to increase the 30Mbps communication bandwidth.

  In this case, when the user A operates the system terminal to make a request for adding a communication network resource, the provider access unit 102 receives a resource addition request signal from the system terminal used by the user A. Subsequently, the resource display control unit 104 extracts a free virtual resource with reference to the virtual resource inventory management table 110 and displays it on the system terminal that is the service request source. Here, it is assumed that the user A selects virtual resources having resource IDs “200”, “300”, and “600” among free virtual resources displayed on the system terminal in the time zone from 10:00 to 12:00 on Monday. . In this case, the resource control unit 106 merges the virtual resource originally assigned to the user A's system terminal with the newly added virtual resources with the resource IDs “200”, “300”, and “600”. . In addition, the resource control unit 106 updates the usage status of the virtual resources with the resource IDs “200”, “300”, and “600” in use in the virtual resource inventory management table 110 as indicated by the broken lines 156 and 158. To do. In this way, in response to the resource addition request signal, a free virtual resource is extracted from the virtual resource inventory management table 110, displayed on the system terminal that is the resource addition request source, and selected, so that the primary resource can be quickly displayed. Secure resources.

  FIG. 7 is a diagram for explaining an example of virtual resource allocation control. FIG. 7 explains the virtual resource inventory management table 110 and the virtual resource inventory payout table 112 when dynamically changing communication network resources. As shown in FIG. 7, in this example, the virtual resource inventory payout table 112 stores the effective bandwidth and the effective hop count in association with the service ID. For example, it is assumed that a certain user B is currently contracting for a service with a communication bandwidth of 100 Mbps. In addition, although a communication bandwidth of 100 Mbps is normally secured for the user B, as shown by a broken line 160 in the virtual resource inventory payout table 112, the effective state of the service is reduced due to a communication network failure or construction at present. Suppose you are.

  In this case, the resource display control unit 104 refers to the virtual resource inventory management table 110 and pays out free virtual resources having resource IDs “600” and “700” to the user B system terminal. The resource control unit 106 merges the virtual resource originally assigned to the system terminal of the user B and the newly allocated virtual resources with the resource IDs “600” and “700”. Further, the resource control unit 106 updates the usage status of the virtual resources having the resource IDs “600” and “700” during use, as indicated by a broken line 162 in the virtual resource inventory management table 110. As described above, in the example of FIG. 7, the resource shortage is detected by checking the effective state of the service while referring to the virtual resource inventory payout table 112. Furthermore, in the example of FIG. 7, primary resource augmentation can be performed without service interruption by paying out free virtual resources from the virtual resource inventory management table 110 and responding.

  Next, the configuration of a communication apparatus that dynamically executes virtual resource allocation control will be described. FIG. 8 is a diagram illustrating an overall configuration of a communication apparatus that dynamically executes virtual resource allocation control. As shown in FIG. 8, the communication system including the communication apparatus according to the present embodiment includes a resource request unit 80, a resource management unit 201, resource management data 209, and a switch control unit 220. The resource request unit 80 and the resource management unit 201 are connected via the communication bus 90. Further, the resource management unit 201, the resource management data 209, and the switch control unit 220 are connected to each other via the communication bus 214. The system terminal 82 included in the resource request unit 80 is the same as that described with reference to FIG. Also, the provider access unit 202, the resource display control unit 204, the resource control unit 206, and the NW control unit 208 included in the resource management unit 201 are the same as those described in FIG. . The virtual resource inventory management table 210 and the virtual resource inventory payout table 212 included in the resource management data 209 are the same as those described with reference to FIG.

  The switch control unit 220 includes a packet reception unit 222, a soft switch unit 224, and a virtual IF (InterFace) queue unit 226. The packet receiving unit 222 receives a packet transmitted from the system terminal 82. Further, the soft switch unit 224 determines to which virtual resource each of the plurality of packets received by the packet receiving unit 222 is allocated. The virtual IF queue unit 226 allocates each packet to each queue in accordance with the allocation determined by the soft switch unit 224, and sequentially transmits the packets stored in each queue to the communication network 216.

  Subsequently, specific processing of the switch control unit 220 will be described. FIG. 9 is a diagram illustrating an example of virtual resource merging using VLAN-VPN. As shown in FIG. 9, it is assumed that packets 302, 304, 306, and 308 are received by the packet receiving unit 222 in the order of (1) to (4). As shown in FIG. 9, the soft switch unit 224 includes a virtual group tag assignment table 223, and selects a line indicated by the tag pointer 225 from the virtual group tag assignment table 223 when a packet is received. The soft switch unit 224 adds a VLAN-tag to the packet and attaches it to the virtual IF queue unit 226 with reference to the tag pointer 225 in the order of arrival of the packet. The soft switch unit 224 rotates the tag pointer 225 in the order of α, β, and γ so that the tag pointer 225 points to the next record each time a VLAN-tag is added to the packet. In this example, VLAN-tags are sequentially added in the order of arrival of packets, so tagα is added to packet 302, tagβ is added to packet 304, tagγ is added to packet 306, and tagα is added to packet 308. Is done. FIG. 9 shows a state in which the processing up to the packet 308 in (4) is completed, and tag β is selected for the next packet in (5).

  FIG. 10 is a diagram illustrating an example of merging virtual resources using VLAN-VPN. As shown in FIG. 10, it is assumed that the packets 320, 322, and 324 are sequentially received by the packet receiving unit 222 in the order of (1) to (3). Further, it is assumed that the packet 320 is “800 Byte”, the packet 322 is “1 Kbyte”, and the packet 324 is “80 Byte”. The soft switch unit 224 includes a transmission byte number counter 227 and a virtual group tag allocation table 223. When a packet is received, a virtual group tag allocation is performed based on a term in which the transmission byte number counter 227 indicates the minimum. With reference to Table 223, a VLAN-tag is added to the packet. Further, the soft switch unit 224 attaches the packet to which the VLAN-tag is added to the virtual IF queue unit 226. Also, the soft switch unit 224 counts up the number of transmission bytes of the selected line by the number of bytes attached to the virtual IF queue unit 226.

  Specifically, when receiving the packet 320, the soft switch unit 224 adds the tag β having the smallest transmission byte number counter 227 at that time to the packet 320, and sets the transmission byte number of the tag β of the transmission byte number counter 227 to “ Count up from “2000” to “2800”. In addition, when the soft switch unit 224 receives the packet 322, the soft switch unit 224 adds a tag α having a minimum transmission byte number counter 227 at that time to the packet 322, and sets the transmission byte number of tag α of the transmission byte number counter 227 from “2060” Counts up to “3060”. Further, when receiving the packet 324, the soft switch unit 224 adds a tag γ whose transmission byte number counter 227 is the smallest at that time to the packet 324, and sets the transmission byte number of the tag α of the transmission byte number counter 227 from “2600”. Counts up to “2680”. In this way, traffic can be averaged by adding a VLAN-tag whose transmission byte number counter 227 indicates the minimum to the packet. FIG. 10 shows a state in which the processing up to the packet 324 has been completed. When the next packet is received, the tag γ whose transmission byte number counter 227 is minimum is selected.

  Next, the virtual resource inventory payout table 112 when merging virtual resources using VLAN-VPN will be described. FIG. 11 is a diagram showing a virtual resource inventory payout table 112 when virtual resources are merged using VLAN-VPN. As shown in FIG. 11, the virtual resource inventory payout table 112 stores VLAN-tags corresponding to each service ID. Here, as indicated by a broken line 350, for each of the virtual resources with the service ID “500” and the resource IDs “300”, “700”, “800”, the VLAN-tag is “α”, “ “β” and “γ” are associated.

  Next, the configuration of the tag pointer 225 will be described. 12 and 13 are diagrams showing the configuration of the tag pointer 225. FIG. As shown in FIG. 12, the tag pointer 225 is associated with a tag pointer for each service ID. Here, as indicated by a broken line 352, it is assumed that VLAN-tag “α” is stored corresponding to service ID “500”. In this state, when the packet receiving unit 222 receives a packet, the packet receiving unit 222 transfers the received packet to the soft switch unit 224. The soft switch unit 224 refers to the tag pointer 225, selects the line (VLAN-tag) indicated by the tag pointer 225, and adds it to the packet. After setting the VLAN-tag in the packet, the soft switch unit 224 attaches to the virtual IF queue unit 226. In addition, when the soft switch unit 224 attaches the packet to the virtual IF queue unit 226, the VLAN-tag corresponding to the service ID “500” indicates the next record as indicated by a broken line 354 in FIG. -Update tag to “β”.
