    Attached is a Fictitious project that I need to a networking solution.
    Please let me know if you can help with my project.

    Please see the text below for the question (in case if the attachment
    is not working.)

    SELL-DIRECT CORPORATION
    Sell-Direct Products, Inc. representatives are being modernized. In
    addition to carrying sample medical equipment in their hospital
    visits, sales representatives now seek to dial-in remotely on their
    sales trips to radically reduce paper from the ordering process.

    After the order data is sent, the system will send error messages and
    confirm the order. The salesperson would then upload the data to
    Sell-Direct's host computer on-site. Sell-Direct's 45 salespeople are
    intended users of the system, with top sellers being offered the new
    system first. Right now, sales reps prepare a paper-based purchase
    order on a booklet-length form. They then mail or fax the purchase
    order to their local Sell-Direct branch, where it is scanned into the
    network and processed. The new system will eliminate the mailing
    entirely and allows sales representatives to sell for two or three
    more days in a two-week sales cycle, rather than stopping early to
    file the written orders. Sell-Direct needs a quick turnaround and an
    answer to their problems. There are approximately 40 orders sent in
    per day by each salesperson. Each sales order is about 250KB large on
    average.

    In the main office there are 25 users of scattered PCs connected to a
    Windows NT LAN running 10BaseT over Category 3 twisted pair. They are
    unhappy with the NT-based LAN and want to upgrade both the network and
    the RDBMS being used-namely Access 2.0. There is only one server-a
    Dell PIII-800Mhz Server with a 100GB drive, whose limits and capacity
    are close to being reached. The departments at Sell-Direct are
    Marketing/Sales, Personnel, Accounting/Finance, MIS, and
    Operations/Purchasing. None of the current 25 PCs will be retained as
    they are mainly Pentium III-333s. They also have no retail value. Of
    the 25 users, 3 are managers.

    In addition, Sell-Direct has four new branch offices with 22 employees
    each in DC, Newark, Silver Spring, and Boston, MA (the main office is
    in Philadelphia). There are 2 managers at each site, but there are no
    PCs yet at these recently-created branch locations. All branches
    should be fully computerized within a budget of $700,000. An extra
    $90,000 is available for automating the sales reps. One imperative of
    the design is to provide a data mart for each location to enable
    managers to perform sales and market analysis for their location
    sales. Philadelphia should be able to perform enterprise-wide
    analyses (not just local), therefore a comprehensive warehouse/mart
    architecture should be designed.

    Finally, Sell-Direct wants a new website to allow medical personnel
    customers to order online from the company. Development costs cannot
    be passed onto the MIS department of Sell Direct (assume web expertise
    is lacking), it must be paid for out of the project budget. Any new
    cabling must also be paid for out of the budget.

    You are also not allowed to increase your budget by firing people or
    selling equipment. Assume the equipment has no resale value. WAN
    costs for leased lines etc. must be paid for out of the budget for one
    year and then absorbed by recurrent budgets.

    GUIDELINES FOR THE DESIGN PROJECT

    A profile of the organization you will be dealing with is given above.
    It describes the general requirements analysis for the problem faced
    by the organization, as well as the organization's major objectives
    and strategies.

    1. Propose the computing and data communications elements needed to
    satisfy the system requirements defined in the given case. You must
    specify the criteria for evaluating the hardware, software and data
    communications requirements of your system.
    Describe your proposed configuration in terms of:
    (a) Client and Server profiles-type, numbers, and configuration.
    (b) Network Operating System (NOS) components for clients and
    servers.
    (c) Topologies and protocols used in the system. Map these against
    the OSI reference model.
    The software used for transaction processing.
    The data warehouse architecture used for analyses and managerial
    reporting at local and enterprise levels.
    (e) The data communications devices used in the network, such as
    hubs, routers, switches etc.
    (f) The hardware and software used for dial-in access by remote
    users.
    (g) The type, protocol, and format of the system's Wide Area Network
    and the types of devices used.
    The structure of the system's database and DBMS-clarifying whether the
    system has a centralized or distributed database.
    The new website's development and structure.

    2. Show your comprehensive system budget.

    3. Perform a thorough cost-benefit analysis of your system. All
    intangible benefits must be quantified.
