Description

  In recent years, opticalization of communication networks has progressed, and GMPLS (Generalized Multi-Protocol Label Switching) has been proposed to control various layers in an integrated manner by optical networks. For example, there is a VNT (Virtual Network Topology) configuration (Non-Patent Document 1). VNT is a topology formed by a plurality of optical paths as a virtual network on a physical network, and an optical path is treated as a link when viewed from the IP layer.

  The VNT configuration refers to a process of changing the topology of the VNT network by setting and releasing an optical path. The VNT configuration requires less topology change cost and change time than a conventional network that physically changes the line arrangement. Then, by efficiently configuring the VNT according to the fluctuation of traffic demand, efficient resources (physical network) with high network utilization efficiency can be used.

  By the way, when a user rents a communication band, determination of a rental fee becomes an important issue.

The technique described in Patent Document 1 is a method for determining a rental fee by auction or bidding. This method is a method in which a plurality of network operators auctions for a user's rent request and decides a network operator to be rented. If there is one network operator, the rent fee may be high. . Further, since the rental fee is determined by bidding of a plurality of users, the rental fee applied by other users is not known, and the user needs to apply for a high rental fee. Also, the rental fee is not necessarily the network operator's desired fee.
JP 2002-230444 A Takashi Miyamura, Rie Hayashi et al., “Implementation and Evaluation of Multi-layer Traffic Engineering Function by PCE”, IEICE, IEICE Technical Report, PN2005-33 (2005-08), pp.75-80

  When the VNT configuration is performed, an extra path is generated. For example, the path between the ground that had a path in the daytime becomes unnecessary at night, or the number of required paths may be reduced and the optical path may be released. Equipment is wasted. Therefore, by lending the surplus path generated by the VNT configuration to the user, the network operator can ensure profit.

  The conventional technology has not provided an appropriate price with a balance between supply and demand for surplus path lending fees generated by the VNT configuration. For this reason, the network operator cannot get a borrower if the rental fee is increased, and cannot recover the facility fee if the rental fee is reduced.

  For example, when a user leases network resources as a dedicated line, it is necessary to adjust the bandwidth of the dedicated line to the peak traffic in order to avoid problems such as quality degradation due to congestion, and the rental fee becomes high. Therefore, a user who wants to borrow at a low price without requiring the quality of a dedicated line cannot borrow network resources.

  If the surplus path lending fee generated by the VNT configuration becomes an appropriate price in accordance with the supply and demand balance, lending is activated and the number of lending increases, which is beneficial to both network operators and users.

  Therefore, the main object of the present invention is to activate lending to a single user for the surplus path generated by the VNT configuration.

In order to solve the above-mentioned problems, the present invention provides an optical path lending method for lending an unused redundant path in an optical network system in which a network topology is virtually configured by an optical path, and the setting of the optical network system The control device is configured as a computer including at least a memory serving as a storage unit used when performing arithmetic processing and an arithmetic processing device that performs the arithmetic processing, and the arithmetic processing device executes a program on the memory. Thus, an information collecting unit and a calculation unit are configured, and before the application period for borrowing for the optical path, the storage means stores, for each optical path, an average value of past usage of the optical path, and Stores data for calculating the initial charge that is associated with the total application amount from past user terminals. When the calculation unit calculates the initial fee that is an initial value of the current amount indicating the rental amount of the optical path, an average value of past usage amounts of the optical path read from the storage unit is calculated. At least one of the calculation method for increasing the initial fee as the value increases and the calculation method for increasing the initial fee as the total value of past application amounts of the optical path read from the storage unit increases. The initial charge is calculated based on the initial charge, and the initial charge is stored in the storage means as the current amount. During the borrowing application period for the optical path, the information collection unit applies for the optical path to be lent. When the information on the user terminal is received, the calculation unit is notified of the user ID and the application amount included in the information on the received application. The calculation unit reads the current amount stored in the storage unit, compares the current amount with the notified application amount, and when the application amount exceeds the current amount, The current amount and the notified user ID are stored in the storage unit in association with each other, and after the borrowing application period for the optical path, the calculation unit Of the current amount stored in the means, the user with the user ID corresponding to the last updated current amount is determined as a rented user, and communication related to the user terminal of the determined rented user is determined. It is set to a communication apparatus on the route of the surplus path of the optical network system so as to be performed on the surplus path .
Furthermore, the present invention is an optical network system setting control device for executing the optical path lending method.

As a result, the user who applied for the maximum amount can reliably borrow the surplus path by the auction method, and the surplus path lending generated by the VNT configuration is activated.
Further, since the initial fee in the auction method is an appropriate price, the communication carrier can obtain a certain profit.

The present invention is an optical path lending method for lending an unused unused path in an optical network system in which a network topology is virtually configured by an optical path, wherein the setting control device of the optical network system performs arithmetic processing It is configured as a computer including at least a memory as a storage unit used at the time and an arithmetic processing device that performs the arithmetic processing, and the arithmetic processing device executes a program on the memory, whereby an information collecting unit and a calculation Before the borrowing application period for the optical path, the storage means stores, for each optical path, an average value of the past usage amount of the optical path and an application amount from the past user terminal. The initial charge calculation data associated with the total value is stored, and the calculation unit When calculating the initial fee, which is the initial value of the current amount indicating the amount of rental of the service, the calculation is made such that the larger the average value of the past usage of the optical path read from the storage means, the higher the initial fee. And calculating the initial fee based on at least one of the calculation methods of increasing the initial fee as the total value of past application amounts of the optical path read from the storage means increases. The initial charge is stored in the storage means as the current amount, and for each predetermined period of the borrowing application for the optical path, the calculation unit stores the current price in the predetermined period in the storage means. The current amount is read out and notified to the user terminal, and when the information regarding the application is not received from the information collecting unit in the predetermined period, the predetermined amount After the current price in the next predetermined period after the elapse of time is set to a price lower than the current price in the predetermined period, the application for borrowing for the optical path is resumed, and information related to the application in the predetermined period is collected in the information collecting unit When receiving from the user terminal of the user terminal that has transmitted the information on the application earliest, the user is determined as a rental target user, and the communication related to the determined user terminal of the loan target user is performed on the surplus path, It is set in a communication device on the route of the surplus path of the optical network system .
Furthermore, the present invention is an optical network system setting control device for executing the optical path lending method.

Thereby, the user who first applied can borrow the surplus path at an appropriate price by the reverse auction method, and the surplus path lending generated by the VNT configuration is activated.
Furthermore, since the initial fee in the reverse auction method is an appropriate price, the communication carrier can obtain a certain profit.

  The present invention is an optical path rental program for causing a computer to execute the optical path rental method.

  According to the present invention, the user can borrow a surplus path at an appropriate price, and the surplus path lending generated by the VNT configuration is activated.

  In addition, according to the present invention, it is not necessary to construct the communication network equipment amount (resource) based on the total amount of user applications, and another user can use the communication network resource (optical Pass bandwidth), and efficient facility operation becomes possible.

  The user can decide whether to borrow while confirming the rental fee of the optical path to be borrowed, and can borrow the optical path at an appropriate fee whenever necessary.

  By soliciting optical path rentals, a communication carrier can share a same optical path by sharing a plurality of users with different activity patterns, and can provide a communication band at a low cost. By performing the VNT configuration, it is possible to effectively utilize network facilities that are excessively wasted depending on the time of day, so that even if the fee is low, the rental fee income increases.

  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1 is an example of a system configuration for explaining the present embodiment. The network system includes an optical network 1 and a setting control device 2. The optical network 1 is configured by connecting edge routers 41 to 44 and optical cross connects 31 to 33, and user terminals 21 to 25 are connected to the edge routers 41 to 44. The setting control device 2 transmits a control message for setting an optical path to each device in the optical network 1. The node is a general term for the edge routers 41 to 44 and the optical cross connects 31 to 33.

  Each device of the network system is configured as a computer including at least a memory serving as storage means used when performing arithmetic processing and an arithmetic processing device that performs the arithmetic processing. The memory is constituted by a RAM (Random Access Memory) or the like. Arithmetic processing is realized by an arithmetic processing unit configured by a CPU (Central Processing Unit) executing a program on a memory. In addition to each device, the present embodiment includes a program for causing each device to execute arithmetic processing, and a computer-readable recording medium that records the program.

  FIG. 2 is an example of an optical path configuration configured in the optical network 1. The optical paths 51 to 53 are set between the edge routers 41 to 43, respectively. For example, the optical path 51 is used for communication between the edge router 41 and the edge router 42.

  FIG. 3 is an example of a WEB screen 61 that is open to the Internet for soliciting optical path rental. The WEB screen 61 includes an application guideline screen 62 and an application screen 63 for the user terminals 21 to 25 to apply. Details will be described later in the description of the operation with reference to the flowchart.

  FIG. 4 is a configuration diagram of the setting control device 2.

  The setting control device 2 includes an information collection unit 11, a calculation unit 13, a database 12, an information processing unit 14, a line setting instruction unit 15, and a control interface with an external device. Hereinafter, each component of the setting control apparatus 2 will be specifically described.

  The information collection unit 11 collects information such as the optical path capacity and free bandwidth, and the borrowing request from the user from the communication devices in the network. As a method of collecting information from a communication device, there are a commercially available measurement system such as NetFlow and sFlow, and a method using a protocol such as SNMP (Simple Network Management Protocol). NetFlow and sFlow are published in the literature “Multimedia Promotion Center,“ Survey Report on Internet Traffic with Broadband Dissemination ”, [online], [Search February 24, 2006], Internet <URL: http: //www.fmmc.or.jp/fileserv/31/1078460548_h029.pdf> ”. NetFlow is a measurement technology from Cisco. sFlow is a measurement technique of InMon (see RFC 3176). Further, as described in Japanese Patent Laid-Open No. 2005-79668, a band to be allocated to the next period may be determined based on a band usage rate in a predetermined period.

  The calculation unit 13 calculates the information in the data table held by the database 12 to the latest value using the information passed from the information collection unit 11 and the optical path information held by the database 12.

  The information processing unit 14 processes the information so that the user can check the information held in the database 12 in the form of a WEB screen 61 (see FIG. 3).

  The line setting instructing unit 15 instructs each edge router to multiplex communication traffic between the user terminals 21 to 25 for which application has been made on the corresponding optical path in time for the rented start time of the solicited optical path.

  The control interface with the external device serves as an entrance / exit for transmitting / receiving information to / from the external device.

  FIG. 5 is a configuration diagram of a data table stored in the database 12 that holds information such as optical path capacity and empty bandwidth.

  The data table includes the start and end nodes for which an optical path is set, optical path route, path capacity, used capacity, rentable capacity, loan bandwidth, application deadline time, loan start time, loan end time, applicant ID, application amount including. The data table also holds network topology information and the like (not shown).

  For example, the path from the edge router 41 to the edge router 42 is applied by two applicants (ABC012, DEF345). The applicant (ABC012) application amount ¥ 200,000 is higher than the applicant (DEF345) application amount ¥ 150,000. Therefore, when the application deadline is reached, the applicant (ABC012) becomes a loan target user. .

  6 and 7 are flowcharts for explaining processing in the case of lending an optical path. It is assumed that the communication band in the optical path 51 is vacant and can be lent to the user.

  FIG. 6 is a flowchart showing an operation flow of the setting control device 2 and the user terminals 21 to 25.

  The setting control device 2 creates a recruitment guideline screen 62 on the WEB screen 61, sets the minimum communication bandwidth lending fee as the current fee 64, and publishes it on the Internet (S1).

  The user terminal 21 acquires the application guideline screen 62, and applies with the application amount 65 higher than the current fee 64 (S2). The setting control device 2 reflects the application by changing and setting the application amount of S2 to the current fee 64 and publishing it (S3).

  The user terminal 22 acquires the application guideline screen 62, and applies with the application amount 65 higher than the current fee 64 (S4). The setting control device 2 reflects the application by changing and setting the application amount of S4 again to the current fee 64 and publishing it (S5).

  Since the user terminal 21 wants to use the communication band of the optical path 51 by all means, the user terminal 21 acquires the application guideline screen 62 again, and applies again with the application amount 65 higher than the current fee 64 (S6). The setting control apparatus 2 reflects the application by changing the application amount of S6 to the current fee 64 and publishing it (S7).

  The user terminal 22 accepts an operation to give up the application from the user because the current fee 64 on the application guideline screen 62 is higher than planned (S8).

  The setting control device 2 determines the lending of the communication band of the optical path 51 to the user terminal 21 of S6 that applied for the highest amount at the deadline of application (S9). The user terminal 21 communicates using the path since the rental target path is set (S10).

  FIG. 7 is a flowchart showing a line lending method in the setting control device 2.

  The information collection unit 11 refers to the data table of the database 12 and searches for an optical path that can be lent out from a free bandwidth or the like (S21). The information collection unit 11 periodically collects the optical path capacity and free bandwidth information from the communication devices in the network, and updates the database 12. Further, the calculation unit 13 may calculate the optimal solution of the optical path route from the latest used bandwidth of the optical path stored in the data table or the bandwidth information of the free bandwidth, and may rewrite the information in the data table as needed.

  The information processing unit 14 acquires information on the optical paths that can be lent from the database 12, and displays the information on the WEB screen 61 to start lending recruitment (S22). The application deadline is determined for each optical pass, and applications are accepted until the application deadline.

  The information collecting unit 11 accepts an application for borrowing for the optical path that has been lent out through the WEB screen 61 (S23). The user who applies later applies for a higher price than the rental fee of the user who applied first, and does not accept the application otherwise.

  Whenever there is an application from the user, the information collection unit 11 registers information related to the application (user ID, bid price, etc.) in the database 12 and notifies the calculation unit 13 of the information related to the application (S24).

  The calculation unit 13 updates the lending solicitation content based on the application history already received and the current application (S25). The user's rental fee is that of the user who applies later.

  The information processing unit 14 processes the lending solicitation contents rewritten in the database 12 to reflect the information on the WEB screen 61 viewed by the user, and displays the latest processed information on the Web screen 61 (S26). The user can view the latest reflected information.

  The calculation unit 13 determines whether or not the branch condition “the application deadline time is satisfied” is satisfied (S27). If satisfied (S27, Yes), S28 is executed, and if not satisfied (S27, No), S23 is determined. Execute. If the answer is S27, Yes, the information processing unit 14 displays reception stop information on the WEB screen 61 in order to stop the lending solicitation, and proceeds to S28.

  The calculation unit 13 determines a user to be lent out for the optical path from the application registered in the database 12 (S28). Since the user who applied lastly applied for the highest rental fee, only the user who applied last is set as the user who is eligible for lending the optical path. Then, the information on the data table held in the database 12 for notifying the lending target user of the lending target optical path is notified to the line designation instructing unit. The information to be notified is information necessary for communicating the communication traffic between the communication devices of the rental target users on the rental target optical path.

  The line setting instruction unit 15 issues an instruction to the edge router to lend the optical path in time for the lending start time (S29). The edge routers 41 to 43 are instructed to communicate the communication traffic between the user terminals 21 to 25 of the lent target user on the lent target optical path.

Table 1 below is a table for explaining processing for determining a rental fee at the start of an auction or a reverse auction (details will be described later) based on the past usage status and application status of the optical path. The table 1 is input by, for example, an administrator and stored in the storage unit of the setting control device 2.

  Table 1 shows, for each optical path, an optical path name, an optical path bandwidth capacity, an average used bandwidth amount during lending, a maximum bandwidth amount, and a lending fee per 10 Mbps. The maximum amount of bandwidth is the total amount of bandwidth requested from the user terminal when lending is recruited. The lending fee per 10 Mbps is a lending fee for the future optical path determined by the setting control device 2 based on the optical path bandwidth capacity, the average used bandwidth amount during lending, and the maximum bandwidth amount.

  Since the optical path 51 has a high usage rate and indicates that there is a case where the application has been made beyond the communication capacity of the optical path, the calculation unit 13 calculates from the information of the data table held in the database 12 and calculates the light. The rental fee per 10 Mbps in the future for the path 51 is set higher than other optical paths. On the other hand, the optical path 53 has a small application bandwidth, a low usage rate, and a large free bandwidth. Therefore, the setting control device 2 performs the same calculation to set the rental fee per 10 Mbps low, thereby improving the usage rate. Increase revenue from usage fees.

  The auction method in which the amount gradually increases from the initial fee has been described above. Hereinafter, the reverse auction method in which the amount gradually decreases from the initial fee will be described.

  FIG. 8 is an explanatory diagram for explaining an example of lending an optical path communication band by the reverse auction method. The reverse auction method is a method of starting with a high rental fee, gradually lowering the rental fee, and adopting the user who applied first. Thereby, since the user only needs to apply once, the user can make a successful bid without being disturbed by the rival user.

  The WEB screen 67 released to the Internet by the setting control device 2 includes a lending recruitment screen 68 for recruiting optical path borrowing users and an application screen 69. When there is a communication band of the optical path that is desired to be lent, the setting control device 2 sets the rent amount in the rent 66 and publishes it on the Internet.

  If there is no application from the user terminal after the lapse of a predetermined period, the calculation unit 13 determines that the data table held in the database 12 has not changed, recalculates the amount, lowers the loan amount, and the rental fee The rental recruitment screen 68 is opened to the Internet again.

  The user terminal obtains the lending solicitation screen 68 and determines whether or not to borrow the bandwidth of the corresponding optical path based on the amount displayed on the lending fee 66. If the amount is satisfactory, the user terminal applies on the application screen 69. .

  FIG. 9 is a graph for explaining the discount rate when the rental fee is discounted according to the application time of the optical pass. In this graph, a higher discount rate is set as the time from the use period of the optical path to the application time is longer. This graph is input by, for example, an administrator and stored in the storage unit of the setting control device 2.

  The borrowing application times T1, T2, and T3 pass in this order. That is, the borrowing application time T3 is later than the borrowing application time T1. For example, if you apply for borrowing at the borrowing application time T3 (for example, three months before the start of use), you can receive a 50% discount on the normal rental fee. On the other hand, if you apply for a loan at the application time T2 (for example, one month before the start of use), you will receive a 20% discount. If you apply for a loan at the application time T1 (for example, one week before the start of use), you will receive a 10% discount. Is shown.

  The setting control device 2 can make a long-term use plan of the facility by publishing the discount fee for the optical path scheduled to be rented on the WEB screen before the borrowing application time T3 and recruiting borrowed users. A new optical path can be created in advance during many periods.

  The present invention described above can be widely modified without departing from the spirit thereof as follows.

  For example, the program executed by the setting control device 2 may be transmitted from a computer system storing the program in a storage device or the like to another computer system via a transmission medium or by a transmission wave in the transmission medium. . Here, the “transmission medium” for transmitting the program refers to a medium having a function of transmitting information such as a network such as the Internet or a communication line such as a telephone line.

  The program may be for realizing a part of the above-described processing. Furthermore, what can implement | achieve the above-mentioned process in combination with the program already recorded on another apparatus, what is called a difference file (difference program) may be sufficient.

  This embodiment can be used for an industry that leases a communication band in an optical path configured in the optical network 1 to a user.
