Since the Western Trucking Mini-case question on page 264 does not say how congested the network is, I will assume that the entire network will be upgraded to include the switches, and routers. The network is already running at 10baseT so I will also assume that the cabling is Cat5e that can handle 1 Gbps and I will not be upgrading the cable drops. Due to the offices and the personnel in the offices, I will create VLAN’s for several of the operating units. I will create the following VLAN’s:
VLAN 1 (Accounting): Accounts Receivable, Accounts Payable, Sales and Marketing, Payroll
VLAN 2 (Administration): Human Resources, Customer Service, President, Security, Mail room
VLAN 3: (Operations) Agent Operations, Intrastate Operations, Interstate Operations
VLAN 4 (Vehicle Management): Fleet Maintenance, Dispatch
VLAN 5 (Information Technology): Information services, Data Processing, conference room
I would purchase Layer 3 VLAN switches and a Router. Each VLAN would be connected to each other VLAN switch and the router using 1Gbps backbone circuits. The router would be responsible for Internet traffic and the VLAN switches would be responsible for managing the traffic within the VLAN and between VLAN’s. The connections to the individual hosts would be primarily with 100Mbps connections (NIC’s). Any servers (mail, database, application, etc.) would be connected using 1Gbps connections. The network would run on Ethernet with TCP/IP as the primary data protocol. The second assigned problem, exercise 9-1 on page 330 asks for a description of the current network structure of Abilene network, vBNS network, and the CA*net network. The Abilene and CA*net are very high speed networks. Abilene is operated in the United States and CA*net is operated in Canada. The two networks are connected. The Abilene network is also known as Internet2. All the major circuits are…...

... Huffman Trucking Operating System Huffman Trucking uses a Windows 3x/9x operating system, as well as Windows 2000 server with proxy server 2 and Windows Exchange 5. Many companies use Windows operating systems because they are simple to use right away as soon as they are implemented as hardware. Put simply, they are more user friendly. Being user friendly and easy to use right away makes for easier training of employees for the operating system and it’s programs. It also streamlines the aspects of the operating system for business applications. Other operating systems, such as Linux for instance, are more in depth with technical applications and require more skill and detail because of its flexibility with manipulating the program. The source code is available for this system, and more of a manual touch is needed. Windows eliminates the need for this, and comes with useful programs for businesses such as Huffman Trucking. Windows comes with helpful programs to help a business with their daily needs. Some of these programs are Word, Excel, and Outlook. These help a business such as Huffman Trucking with documenting, scheduling, inventory, database management, and e-mailing and communication.

...Huffman trucking originated in Cleveland, Ohio in 1936, because of World War II the company grew due to the increasing demand of materials. By 1945 the company had grown exponentially, thanks to the relationship forged with the United States Government. Today the company has grown to a nationwide transportation company with 1,400 employees and hubs in Los Angeles, California, Saint Louis, Missouri, and Bayonne, New Jersey with its central facility still located in Cleveland, Ohio. The company today has over 800 tractors, and has expected revenue of $600,000,000 for the 2004 fiscal year (Apollo Group, Inc, 2003,2004,2012). When reviewing all of the facilities and systems within every single facility it’s noticeable that they are all running independent systems, which some don’t even have firewalls installed for the network. Compiling all of the systems in the four offices, and plants we find different operating systems (OS). This OS include Windows 3.1, Windows 3.X, Windows 9.X, Windows NT, Windows 95, Windows 98, Windows 2000 Professional, Windows XP Professional, Mac OS, Novel Netware 4.11, Windows 2000 Server, Windows Proxy Server 2, Windows Exchange 5, and CISCO (Apollo Group, Inc, 2003,2004,2012). In addition, to different types telephonies systems, webmail servers, and different types of hardware in every location. I don’t believe the OS were chosen by the Ohio office per say.

...increase in long-term debt (11.4%). This indicates that most of the financial expansion of Huffman Trucking was in cash or cash equivalents or by taking on additional long-term debt. The horizontal analysis of the 2020/2011 income statement data shows total operating expenses increased 15.3%, but most of that seems to be related to an increase in fuel expense (23.1%). Additionally, an increase of 14.4% in revenues from the previous year was noted. The steady increases in income improved the company’s ability to obtain debt and equity financing. Vertical Analysis Vertical analysis evaluates data in terms of a percent of a base amount. This type of analysis allows for comparison of data to industry competitors of different sizes and industry averages, but can also be used within the company. Analysis of the 2010/2011 balance sheet data shows the percent of cash increased from 22.7% to 33.5% of total assets and the percent of accounts receivables decreased from 31.9% to 19.4% of total assets, suggesting that more revenue was received in the form of cash or cash equivalents than with credit. Vertical analysis of the 2010/2011 income statement data shows significant changes in the percent of salaries, wages and benefits (decrease: 38% of revenue in 2010 to 36.6% in 2011), the percentage of fuel expense (increase: 26.7% of revenue in 2010 to 28% in 2011). This indicates Huffman trucking is maintaining its expenses in relation to its revenue even with the rising fuel......

...Huffman Trucking Operating Systems Huffman Trucking Operating Systems Huffman Trucking, a national transportation company, employs 1,400 employees. Huffman’s hubs are in Los Angeles, California, St. Louis, Missouri, and Bayonne, New Jersey. Huffman’s corporate offices and service center is in Cleveland, Ohio (University of Phoenix, 2012). Computers were basically still in an infantile stage when Huffman began his company in 1936. Companies need methods to assist them in standardizing their business processes. Computers can help companies meet this unique challenge. Operating systems (OS) are an essential part of any computer system. Any major OS will evolve over time because of hardware upgrades or new types of hardware, new services, and fixes (Stallings, 2009). However, one of the purposes of an OS is to provide an environment in which a user can execute programs in a convenient and efficient manner (Silberschatz, Galvin, & Gagne, 2009). Huffman was primarily focused on expanding his business and not much on standardizing business processes across company locations, let alone invest in additional technology to do so when he began his company. Furthermore, Huffman spent sufficient capital in increasing its fleet size and the acquisition of five Eastern regional carriers to add to its existing two Mid-West offices and plants. Additionally, Huffman was recognized as the first major freight carrier to outsource 100% of its information......

The company has hubs in Los Angeles, California; St. Louis, Missouri; Cleveland, Ohio; and Bayonne, New Jersey. The company maintains a truck maintenance facility at the hub in Cleveland, Ohio. Each hub maintains a data center, linked to the corporate offices through various Internet access methods. Recent reports of computer hacking and database corruption have highlighted the need for a coordinated data security and disaster recovery plan. A comprehensive corporate-wide strategy for data security, site backup, and disaster recovery will allow the company to continue to function and communicate during emergencies that involve any of the company’s data hubs and minimize effect on company operations. Huffman Trucking Disaster Recovery Plan Project Objectives “On August 28, 2005, Hurricane Katrina hit the southern coast of the United States with devastating effect.

...Trucking by Warren Fleming A Research Project Proposal Submitted in Partial fulfillment of the Requirements of Completion of LMGT 1321 Materials Handling Lone Star College Cy-Fair Campus Houston, TX June 2015 Almost every industry in today’s economy relies on large tractor trailers to deliver their goods and materials across our country’s roadways. You cannot travel anywhere these days without seeing a multitude of trucks that are hauling all sorts of commodities from one place to the next. The men and women that operate these trucks, leave their families sometimes for days or weeks at a time to keep up with the supply of products that you and I depend on every day. In recent years there have been many regulatory changes due to concerns over both safety, and the environmental influence. These transformations have been at the forefront of a number of technological advancements in the trucking industry. Before the trucking industry goods were transported across the United States by the rail road system. The trucking industry grew to a transportation industry leader after “[c]ongress provided funds to build the Interstate Highway System, an extensive network of highways and freeways that linked major cities across the continent” (Trucking Industry in the United States). These highways have benefited the trucking industry in several different ways. For example these multi-lane highways have no intersections that require a driver to stop therefore,......

It began with small group of thoughtful, committed individuals who’ve been focused on increasing the percentage of women employed in the trucking industry. The article brings attention to the fact that, although women make up half the labor force, a very small percentage are in the trucking industry. One of the goals the Women in Trucking organization has is to address reasons why women aren’t fairly represented in trucking industry roles. They’ve conducted research to better understand what women are looking for in a company, what values attract them and where to find potential female drivers.

...scheduling, routing, mode selection, transloading and other value- added services related to the transportation of freight, which may or may not involve the use of Company owned or owner-operator owned equipment. According to the American Trucking Association’s “American Trucking Trends 2011” report, the trucking industry transported approximately 68% of the total volume of freight transported in the United States during 2009, which equates to 8.8 billion tons and approximately $544 billion in revenue. The truckload industry is highly fragmented and is impacted by several economic and business factors, many of which are beyond the control of individual carriers. The state of the economy, coupled with equipment capacity levels, can impact freight rates. Volatility of various operating expenses, such as fuel and insurance, make the predictability of profit levels uncertain. Availability, attraction, retention and compensation of drivers also affect operating costs, as well as equipment utilization. In addition, the capital requirements for equipment, coupled with potential uncertainty of used equipment values, impact the ability of many carriers to expand their operations. During the recession, the Long-Distance Freight Trucking industry faced difficult conditions and falling demand. The decline in consumer spending drastically reduced the amount of freight that needed to be transported, causing revenue to fall 18.5% in 2009 alone. Meanwhile,......

...Huffman trucking uses the following operating systems in their various locations: Windows 3.1 Windows 3.x Windows 95 Windows 98 Windows 9.x Windows NT Windows 2000 Professional Windows XP Professional Windows Exchange Server 5 Windows Proxy Server 2 Novel Netware 4.11 MAC OS I believe these operating systems were chosen because, at the time they were put into use, they were state f the art operating systems. As the company has grown, focus has been on other areas of the company and its operations. As the company grew and the need for more computers grew, the company seems to have simply added the needed systems with whatever operating systems were current on the systems they purchased. The biggest implications of the operating systems in use by Huffman Trucking would be compatibility. As technology advances and older technology reaches end of life, the ability to maintain a network of computers using so many varied operating systems becomes increasingly difficult. Another implication is using so many different technologies (Windows-based vs. Novel vs. Apple) can cause problems in compatibility, rendering certain systems and software unable to do the tasks that are needed to be performed. Maintaining such an eclectic network likely requires many man-hours that would not be necessary if all of the systems were closer to current, and if they were more closely matched to each other. An example would be if the server software were more current, the desktop......
