Description

[0001] The present invention relates to a system for setting a bandwidth and an apparatus for time reservation,

The present invention relates to a setting system for intuitively providing bandwidth setting and time reservation.

The emergence of Software Defined Networking (SDN), which is led by OpenFlow, is increasingly being applied not only to network provisioning within the data center or between data centers, but also to provisioning of backbone networks or leased lines of telecommunication carriers. Software-based network control enables automated network management to reduce annual maintenance costs, shorten the time from service request to completion to network, and simplify a series of complex processing steps that were handled manually Create new service launches and business models.

Bandwidth-on-Demand (BoD) is a new service based on SDN that can freely change the bandwidth according to the user's demand. It is attracting attention recently because it allows the user to freely set the fee and bandwidth according to time. The BoD service can be combined with Dynamic Pricing (DP), which offers different rates for different time periods, enabling customers to construct services economically according to their usage patterns.

Since BoD and DP concepts are not generalized, and there are no commercial applications or products, there are only a few examples for Proof-of-Concept (PoC). In other words, only the case where the user requests bandwidth change at one time in a specific time zone is assumed. In order to apply a plurality of change requests, each change input must be repeatedly performed, and the bandwidth change setting can be grasped at a glance There is a difficult problem.

Also, it does not consider the situation of periodically changing bandwidth such as "every Saturday from midnight to noon on Sunday". In order to provide natural usability and minimize user inconvenience, it is necessary to provide a user-friendly interface that can change the bandwidth in an intuitive and simple manner.

Therefore, the present invention provides a setting system for intuitively providing a usage bandwidth setting and a time reservation.

The BoD scheduler includes: a parser for analyzing the bandwidth setting information and extracting the bandwidth reservation start time, the end time, and the bandwidth information, and transmitting the extracted information to the DPE; A timer for registering the requested bandwidth reservation start time with a user and causing the bandwidth change command to be transmitted to the SDN controller at the bandwidth reservation start time; And a DAO (Data Access Object) for accessing the database storing the bandwidth setting information and checking the stored bandwidth setting information.

Wherein the setting system comprises: a database for storing and managing bandwidth reservation information set by the user; And an Element Management System (EMS) for monitoring and controlling the plurality of network elements so as to provide the bandwidth requested by the user at a time requested by the user.

The user interface may provide a graph of a time axis x axis and a bandwidth y axis to allow the user to intuitively set the bandwidth.

The graph may include a zoom in / zoom out button that changes the time unit of the x axis to one of year, month or day.

The graph represents a line representing a bandwidth graph, and when the line is selected by the user and moved to one of upper, lower, left, and right, and the height of the line or the width of the graph is changed, the changed bandwidth can be reflected.

If the user presses the graph for a time longer than a preset time, the iterative setting window to be provided to the user can be activated so that the changed bandwidth can be repeatedly provided.

According to the present invention, an intuitive and consistent user input / output method for QoS change such as a bandwidth change is provided in providing a network service, so that a user can easily reserve a desired bandwidth and a desired time slot.

1 is an exemplary diagram of a general bandwidth reservation method.

As shown in FIG. 1, the user determines a bandwidth reservation end time by selecting a desired bandwidth, a delay time, a protection switching method, and selecting a start time and a duration to apply the selected requirements. If a strict start-to-end time is not required, select the "Flexible" item to allow the service providing system to flexibly determine.

In this way, a general large width reservation method assumes that a user requests a bandwidth change at one time only in a specific time zone. In order to apply a plurality of change requests, each change input must be repeatedly performed, and it is difficult to grasp the bandwidth change setting based on the time axis at a glance.

Also, it does not take into account situations in which the bandwidth is changed periodically (for example, "every Saturday from midnight to Sunday at noon"). Therefore, in order to provide natural usability and minimize user inconvenience, it is necessary to provide a user-friendly interface that can change the bandwidth in an intuitive and simple manner, which will be described with reference to Figs. 2 to 6.
