Description

  The present invention relates to a communication service, and in particular, a dedicated line construction system and a dedicated line interconnection control program for providing a service by a dedicated line constructed by connecting access lines of a plurality of carriers and a relay line of a plurality of carriers to each other. About.

  The leased line services mainly used by corporate users include IP-VPN (Internet Protocol-Virtual Private Network) and wide area Ethernet (in addition to conventional digital leased lines, ATM (Asynchronous Transfer Mode), and Ether leased lines. The provision of virtual leased line services such as R) is becoming widespread, and users can select various services according to the interface and line speed.

  However, in these leased line services, the access line between the user terminal and the subscriber accommodation station of the carrier is a cable such as a metal line or an optical fiber. There was a problem that it took several weeks to several months. Further, when a user terminal is relocated, a service interruption period for newly laying this cable occurs, and the flexibility for starting or changing a service is lacking.

  On the other hand, in recent years, ADSL (Asymmetric Digital Subscriber Line) using an existing metal telephone line cable, FWA (Fixed Wireless Access) using wireless as a technology that can easily construct an access line with a speed of several hundred kbps to several tens of Mbps. ) Etc. have been developed.

  By utilizing these high-speed access lines for dedicated line services, it is possible to provide a variety of service types and shorten the time required for initial introduction and configuration change.

  For example, as an example of a service that has already been started, there are IP-VPN using ADSL as an access line, wide area Ethernet (R), and the like.

  However, in general, these access lines and relay lines are often provided by different providers, and it is necessary to negotiate the interconnection between the providers. The contents of the negotiation include setting of line charges for mutual connection, exchange of user billing information, and the like.

  In addition to existing digital leased lines, ATMs, Ethernet leased lines, ISDN, etc., there are various access lines such as xDSL (DSL system service), FWA, FTTH (Fiber To The Home) and CATV (Cable TeleVision).

  For this reason, it is practically difficult for the trunk line operator to negotiate connection with many access line operators. The problem of connection negotiations was a major impediment when diversifying the types of leased line services.

  An example of a method similar to solving such a problem is described in, for example, Japanese Patent Application Laid-Open No. 11-68737 (Patent Document 1) and Japanese Patent Application Laid-Open No. 2000-232447 (Patent Document 2).

  In the method of Patent Document 1, when a user uses a dedicated line, a relay line is automatically selected by setting in advance a user number, a password, etc. when the user connects to a dedicated line reseller. It can be done.

  According to this method, various leased line resellers can be appropriately selected according to the communication destination telephone number. This makes it unnecessary for the user to input a number of numbers other than the destination number.

  Further, in the method of Patent Document 2, an optical line transmission network (hereinafter referred to as an access network) connected by an optical wave transmission network of a carrier company (a communication company having an infrastructure) and a LAN (local communication network) connected to the optical wave transmission network. Are abbreviated to each other via a light wave transmission device, and the light wave transmission network system including the access network system and the relay line is managed by one network management system.

As a result, the operating system of the access network and the operating system of the lightwave transmission network including the relay line can be merged, and it is possible to promptly avoid and recover from a network failure.

When using a high-speed access line, the user has to pay a high usage fee even if the amount of information required is small.

  Furthermore, when the user selects an access line, a connection negotiation between a specific trunk line operator and the access line operator is required. However, connection negotiations between a specific trunk line operator and a large number of access line operators are difficult in practice, and the method of Patent Document 1 does not solve such a problem.

  In the method disclosed in Patent Document 2, a carrier-based lightwave transmission line network and an access line network connected by a LAN connected to the lightwave transmission line network are connected via a lightwave transmission apparatus. One network management system manages an optical transmission line network system including an access line network system and a relay line.

  According to the method of Patent Document 2, the access line network and the relay line network can be collectively managed.

  Referring to FIG. 4, firstly, the interconnection operator 140 performs line interconnection between the other access network operators 120 and the relay network operator 130 (step 401).

  Next, the conditions (step 402) and the connection fee regarding the interface, line speed, guaranteed bandwidth, redundant configuration, etc. are determined (step 403).

  After doing the above, a connection contract is established (step 404).

  Next, after laying the cable and setting the devices of both companies (step 405), the connection line is opened (step 406).

  After the line is opened, the interconnection operator 140 updates the network information database 43 related to the connection information (step 407).

  FIG. 5 is a flowchart showing an example of the flow of interconnection from the user 10 to the start of service use according to the present embodiment.

  In the example of FIG. 5, it is assumed that the interconnections have already been completed between the operators. Specifically, in the switching unit 46a provided on the Tokyo side in FIG. 3, the ADSL network 20p, the ATM network 20q, the Ethernet dedicated line network 20r as the access network, the IP-VPN 30p as the relay network, and the digital dedicated line network 30q are connected to each other.

  In this case, the IP-VPN 30p which is a relay network is transmitted between the two bases of the switching unit 46a and the switching unit 46b provided in the dedicated line construction system 40 together with the dedicated line paths 50a and 50b. In this case, the usage charges are lower and the cost effect can be improved by using these paths as one line rather than separately using these paths from the provider providing the IP-VPN 30p.

  For example, assuming that the bandwidth of the path 50a is 1.5M and the bandwidth of the path 50b is 6M, the aggregated path 51 of 7.5M or more, which is the sum of both bandwidths, is secured and the switching provided in the dedicated line construction system 40 is provided. This can be realized by joining and separating two paths in the unit 46a and the switching unit 46b, respectively.

It becomes possible to do. Therefore, when the bandwidth of a line provided by one operator is insufficient in a section of a certain relay line, a broadband dedicated line path is provided by using a combination of lines provided by a plurality of operators. It becomes possible.

  In addition, when a line failure occurs in any one of the relay networks 30a and 30b, a function for distributing all traffic to the other relay network is installed in the traffic distribution unit 48, so that a dedicated line path relay line can be provided. It becomes possible to carry out route redundancy between operators, and the reliability of the line can be improved.
