    Overview of the Appraisal of Completeness for Software

    Kwon, Ki Tae | 2015, 11(2) | pp.1~8 | number of Cited : 4
    Abstract PDF
    Appraisal of the completeness of a computer program is carried out in various forms such as the calculation of completeness ratio on the development process, defect ratio, calculation of development costs and re-development costs. The guidelines of the appraisal of completeness of a computer program is presented to promote phased execution content so that it can be used as a guideline for the appraisal of completeness, it is applied to the practical appraisal work for the completeness and calculation of development cost of the computer program. The emphasis in order to provide examples of the variety of artifacts required to complete the appraisal work, the person in charge to be able to seek a solution in particular the appraisal complaint. In this paper, it is configured as a basic document to introduce the guidelines of these appraisals of the completeness of a computer program.

    A Comparison for PCB Design Evaluation

    LEE KYU TAE | 2015, 11(2) | pp.10~15 | number of Cited : 0
    Abstract PDF
    The conflict is in the copyright ownership issues in technical abuse and illegal to Information devices system. A person involved in development process moved to other company with the important materials of the product illegally, and then he made a similar product compared with first system. it happens to make a lot of loss to first product company. To compare to two product, the copyright association took an estimation to the first product and illegal copy product. At this time, both company must submit all the materials to be referenced to their assistance. because both developer is a person who have a best knowledge to the product. In this paper, we tried to suggest a work procedure and extract an estimation factors to helping the verification of PCB circuit, especially.

    An Analysis of Benchmarking Methodology for Traffic Management

    Younseo Jeong | 2015, 11(2) | pp.17~22 | number of Cited : 0
    Abstract PDF
    The Benchmarking Methodology Working Group (BMWG in IETF) will continue to produce a series of recommendations concerning the key performance characteristics of internetworking technologies, or benchmarks for network devices, systems, and services. RFC 7640 discusses and defines a practical methodology for benchmarking the traffic management capabilities of networking devices. Also, it defines the methods to characterize the capacity of the following traffic management features in network devices: classification, policing, queuing/scheduling, and traffic shaping. It provides a framework to conduct repeatable traffic management benchmarks for devices and systems. And, this framework can also be used as a test procedure to assist in the tuning of traffic management parameters of benchmark for devices and systems.

    Performance Analysis of TCP Traffic by WLAN Handover Trigger

    Jang-Geun Ki | 2015, 11(2) | pp.23~29 | number of Cited : 0
    Abstract PDF
    In the preceding research of optimization of the beacon Rx power threshold for scanning trigger in WLAN, the newly developed WLAN simulation model to minimize the packet loss has a new scanning procedure to search other access points a little bit earlier than usual by using the counter of the received beacons that have Rx power less than the predefined threshold. In this paper, performance analysis under various multi TCP traffic environment has been done and the usefulness of the developed WLAN simulation model has been verified.
