The present invention relates to a method for providing an ultra-high speed leased line service using a time stamp algorithm having a service characteristic and a variable speed setting function. More specifically, the asynchronous transmission method (ATM) provides a leased line service based on the needs of users and service providers. The present invention relates to a method for providing a high-speed leased line service using a time stamp algorithm having a variable speed setting function that provides technology and reduces resource utilization and user cost.

Conventional leased line services have limitations in the speed at which they can be provided (E1 and below and DS3), and they also have to pay a fairly high price for their services.

This is because the existing dedicated line facility itself is inflexible in providing various high-speed services, and the use facility is dedicated to a particular subscriber. In terms of service providers, speed limitations and expensive services are obstacles to subscriber utilization.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and has a service characteristic and a variable speed setting function for accommodating a large number of subscribers by providing a high speed service to subscribers at a flexible and relatively low price. The purpose of the present invention is to provide an ultra-high speed dedicated line service providing method using a time stamp algorithm.

In order to achieve the above object, a method of providing a high speed dedicated line service using a time stamp algorithm having a service characteristic and a variable speed setting function according to a preferred embodiment of the present invention is a service for all subscribers using a high speed dedicated line service. Creating a service usage time stamp based on information on usage status of each star;

Reading the service usage time stamp and notifying the subscriber that the requested connection resource has been allocated to the subscriber when the value read is within the range of time required for allocating resources; And

If the value read from the service use time stamp is within the service removal or service collection time, the service use bandwidth and service connection of the corresponding subscriber are removed.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention in more detail.

The procedure of using the service according to the embodiment of the present invention is shown in FIG.

The high-speed leased line service user writes information on subscriber information, used service, service usage period, direction, and bandwidth according to the application form designated by the operator, and provides the service provider to the service provider based on the form. Notify us of availability and, if possible, the date of opening.

When the communication line is established and notified to the subscriber, the subscriber performs the requested service during the period of use with confirmation of the opening, and the network operator performs the operation and management work according to the use.

2 is a diagram illustrating a process of making a service use request with a service characteristic and a variable speed setting function for each subscriber according to an embodiment of the present invention.

The subscriber management system 10 holds information on the service status of each service for all subscribers using the high speed dedicated line service, and based on the information, the subscriber management time stamp 15 is prepared to create a high speed dedicated service. The management system 20 is requested to use the resource.

According to the subscriber service usage time stamp 15, the ultra-high-speed dedicated service management system 20 may determine t _max (the maximum time it takes for the ultra-high-speed dedicated service manager to allocate resources) and t _min (the high-speed dedicated service manager uses resources). Perform the request for resource utilization at a time between

The resource use request and resource configuration manager update are performed between the high-speed dedicated service management system 20 and the resource configuration manager.

3 is a diagram illustrating a time stamp algorithm having a service characteristic and a variable speed setting function applied to the present invention, wherein the time stamp algorithm is created in the subscriber management system 10.

The new subscriber S may request to subscribe and modify a service before the maximum time t _{dedicated provision_max} required to provide a service designated by the service provider (step 30).

Each exchange can provide a dedicated line with a constant bit rate (CBR) service and a variable bit rate (VBR) service, and the capacities of the CBR service and the VBR service can be designated at the exchange. The new subscriber S is selected between the CBR service and the VBR service (step 32).

The total bandwidth for each direction that can be provided by the high-speed dedicated network is already provided by the high-speed leased line service for each service-switching exchange for B _{total_fward} [CBR], B _{total_bward} [VBR] _, B _{total_fward} [CBR], and B _{total_bward} [VBR]. bandwidth of B _{assign_fward} being provided for _{[CBR], B assign_bward [VBR} ], B assign_fward [CBR], B assign_bward value less the _{[VBR] B avail_fward [CBR]} , B avail_bward [VBR], B avail_fward [CBR] For B _{avail_bward} [VBR], new subscribers within the range request B _{need_fward} and B _{need_bward} values at the start time t _x of service use, and return B _{need_fward} and B _{need_bward} values at the end time t _y (step 36). ). Here, B _{total_fward} [CBR] is the total bandwidth of the network from the terminal to the network in the CBR service, and B _{total_bward} [VBR] is the total bandwidth of the network from the network to the terminal in the VBR service. The B _{avail_fward} [CBR] is the available bandwidth of the network from the terminal to the network in the CBR service, and the B _{avail_bward} [VBR] is the useful bandwidth of the network from the network to the terminal in the VBR service. The B _{need_fward} is a bandwidth required by the user in the network direction at the terminal, and the B _{need_bward} is a bandwidth required by the user in the network direction at the terminal.

If the bandwidth usage of the total subscriber exceeds the range allocated for the high speed leased line service (YES in step 34), the high speed leased line service management system 20 should perform a procedure for capacity expansion (step 38). ).

If the service modification request is received before the maximum time t _{dedicated provision_max} necessary to modify and provide the service (step 40), the subscriber service use time stamp may be modified according to the needs of the subscriber (step 42).

In the embodiment of the present invention, in step 32, there is a fixed type that requires a constant bandwidth and an unfixed type that requires a constant bandwidth, depending on the manner in which the subscriber S requests the CBR service or the VBR service. It can also be provided symmetrically and asymmetrically for each.

If user (S) requires non-fixed type, it should request service characteristics and service rate before the time required for resource allocation. In addition, the non-fixed form may be classified into a normal form and an irregular form according to whether or not the periodicity requires the same bandwidth at the same time period during the subscription period.

Fixed_symmetric ultrafast leased line service is basically the same as the existing leased line. However, ATM technology enables the ATM switch to be deployed without additional equipment by simply adding additional relay lines even if the demand for input lines increases. Thus, it has the advantage of being easy to expand. Asymmetric services are easy to access, requiring high bandwidth on one side and low bandwidth on the other, such as the connection between the main office and branch offices.

Unfixed high-speed leased line service is suitable for financial services or data backup, where bandwidth use varies greatly with time. Non-regular ultra-high speed dedicated line service is easy for the task where data backup time is fixed, and non-fixed_non-regular allows user to request service of various bandwidth as needed.

4A is a flowchart illustrating a procedure for providing a subscriber with a high speed dedicated line service according to an embodiment of the present invention.

The high speed dedicated service management system 20 reads the subscriber service usage time stamp (step 50). For a value from the subscriber service usage time stamp, when the ultra-fast dedicated service management system 20 reaches a range of time to allocate resources (YES in step 52), the ultra-high-speed dedicated service management system 20 sends a connection manager. By providing the necessary connection information and making a request, the connection manager notifies through the interaction with the resource configuration manager that the requested connection resource (bandwidth, VPI value, etc.) has been allocated (steps 54, 56, 58). _x of x means start time. Figure 4b is a flow chart illustrating a procedure for removing a high-speed leased line service provided to a subscriber according to an embodiment of the present invention.

The high speed dedicated service management system 20 reads the subscriber service usage time stamp (step 60). If the value read from the subscriber service usage time stamp is in the range of service dismantling or collection time (YES in step 62), the high-speed dedicated service management system 20 performs the dismantling or collection request to the connection manager, and the subscriber (Si) Remove the bandwidth and connection from the server (steps 64, 66). The collection here does not mean the end of the service, but means the end of each cycle in the fixed bandwidth service or the periodic dedicated service. In FIG. 4B, _y of t _y means an end time.

According to the present invention as described above, the ultra-high speed dedicated line service, along with the provision of the existing leased line service, can provide the subscriber request service characteristics and symmetrical / asymmetric functions at the time the subscriber requests the ultra-high speed service, Since it can be provided periodically or the connection bandwidth can be changed according to the needs of the subscriber, it is possible to provide a high-speed leased line service up to 135Mbps to the subscriber, and can provide CBR service and VBR service according to the traffic characteristics of the subscriber.

In addition, the symmetrical and asymmetrical services may be provided in bandwidth designation in each direction according to the form required by the subscriber, and may have periodic characteristics or may be provided in a subscriber request type for the unfixed high-speed dedicated line service.

On the other hand, the present invention is not limited to the above-described embodiment, but can be modified and modified within the scope not departing from the gist of the present invention, such modifications and changes should be regarded as belonging to the following claims. will be.
