Chapter 4:
Mini Case 1: Smith, Smith, Smith, and Smith is a regional accounting firm that is putting up a new headquarters building. The building will have a backbone network that connects eight LANs (two on each floor). The company is very concerned with network errors. What advice would you give regarding the design of the building and network cable planning that would help reduce network errors? I have to make some assumptions regarding the network design for this new building. Since they are a regional accounting firm, constructing a brand new building, and mainly concerned with network errors and data reliability, I have to assume that cost is a lower priority. Cost is always a concern, but having accurate information is the

You can very quickly tell whether you have built a poor connector on either end, or if you do not have a solid connection to the switching hardware device. On the cost side, I would contend that the support for future growth in bandwidth and error minimization should easily offset the cost difference.
On the distribution layer, I would suggest using V-LAN devices that are interconnected. By using V-LAN devices you can easily provision separate LANs on each floor while still supporting any network changes in the future. V-LAN devices can provide both switching and routing capabilities because they act as both layer-2 and layer-3 devices. This is a huge advantage in the fact that you can provision separate subnets for each LAN while still allowing certain IPs the ability to communicate to either subnet. This is setup in the router side of the V-LAN software. The V-LAN also easily supports the adding of more user machines (with enough fiber runs established) electronically. Opponents will say that V-LANs required the added expenses of more knowledge and management than the more standard design of separate physical switches and routers. I agree, but we have to keep in mind that this is a new construction process. We want to ensure that we have appropriate hardware to support future growth potential whether it is in
The United States Court of appeals ruled that the suppressed evidence is purely impeaching evidence and no defense request has been made, the suppressed evidence is material only if its introduction probably would have resulted in acquittal. Given a minor role of Phillips' testimony and the limited impact that Phelps statement had on the jury's assessment of Phillips credibility, Maddox could not demonstrate that so the evidence probably would have resulted in an acquittal. Also, the evidence was immaterial under United States V.Blasco; the defendant filed a joint motion to suppress all physical evidence gathered by the officers and any statements made by the defendant. The magistrate found that the defendant did not have to raise a fourth amendment challenge and its suppression did not violate his (Maddox’s) due process right. For ongoing reasons, the district court's dismissal of Maddox's habeas petition was affirmed.
As mentioned in the introduction of the mini case, Hobby Horse Company, Inc. (HH) experienced a tough year in 2011. HH opened up a number of new stores but experienced a poor Christmas season. Christmas season is the biggest sale period for retail stores. As a result, bad Christmas sales performance played a big part of HH’s loss for year 2011. As we computed the financial ratios for HH, we can see the effects from new stores openings and poor sales performance.
On a snowy January evening, the Midwestern Medical Group (MMG) management team held a retirement party for Judith Olsen, MMG president. During the evening, Olsen reflected back on the years she had worked for MMG with mixed feelings about her experience. Over the course of their eight-year integration
The proposed network is designed to serve DesignIT which consist 56’x36’ office space, 4 cubicles, 1 office, 1 server room, 1 receptionist desk and 1 conference room.
Omni Automated Systems has over 40 years of experience in manufacturing state of the art electronic assembly equipment. The company sells equipment to electronics manufacturers. Bob Waters is a field sales engineer working for Omni and he has received news that he has lost a sale with Gentech Office Equipment Company. Gentech manufactures a variety of office equipment. They have recently fallen behind in the industry and have experienced market share and profit margin erosion. In order to turn this around they are looking to revamp, modernize, and automate its manufacturing facilities. They will need a new soldering line to automate their manufacturing and are looking to purchase a robotic test cell. Steve Anderson is the purchasing agent
So therefore, based off the information provided, I would recommend a packet switched architecture, or more specifically a Frame relay with a CIR 45 Mbps WAN service. Frame Relay is packet switched data link layer protocol that handles multiple virtual circuits using High-Level Data Link Control (HDLC) encapsulation between connected devices. (Cisco, 2005) In many cases, Frame Relay is more efficient than X.25 and generally less expensive than ATM. Also the data provided does not suggest that MegaCorp specifically has needs for the extensive QoS information that ATM provides that would enable the setting of very precise priorities among different types of transmissions such as high priority for voice and video and lower priority for email. If the company were a consulting firm with a high propensity for needs on bandwidth because of video conferencing or high bandwidth requiring applications then perhaps ATM architecture with a T1 or T3 WAN service might be more suitable. Even though MegaCorp is a large manufacturing firm recommending Ethernet services might prove to be too expensive of a proposal as well and thus causing us to lose the project. The cost associated to having each factory connected by fiber optic cables to the provider’s city wide MAN backbone plus the cost of the Ethernet switch might not be justified by the company’s bandwidth needs.
1. Is Coconut’s February 1, 2012, arrangement with Buffett within the scope of ASC 985-605?
Main Building – will require 7 computer stations with the most recent version of Operating System to ensure compatibility and networking capabilities between each stations and the ability to communicate between the two locations. They will require three servers, one for web hosting, one for database management and one for emergency failure of any one server. These stations should be networked to communicate with one another for proper data connection especially in the event of any one computer station crashing. Each work station will need to be linked to each server for web hosting and data backup. The cabling used for inside the main building should be 100Base TX cat 5 UTP, for Wi-Fi and WLAN with guest access that is highly secure and reliable, we recommend a device that is capable of supporting up to 15 different users with 450 Mbps. There needs to be 4 printer services in this building. Printer 1 should have
Chick-fil-A is known for their famous Chick-fil-A sandwich, but also for their private, family –controlled ownership structure, philosophy on management and biblical principles. Chick-fil-A uses the differentiation strategy to set them apart from other fast-food chains. Chick-fil-A mission was “To glorify God by being faithful steward of all that is entrusted to us and to have a positive attitude influence on all who come in contact with Chick-fil-A”, and to be “America’s best quick-serve restaurant.” One of their strategies they use to set them apart was focusing on people. This strategy included interview process, golden rule, consistent
Note to instructor: An alternate answer could be a single large LAN for the entire headquarters, interconnected via a WAN to the field offices.
5. Administration departments spread over another 10 buildings. LAN IP’s: Building 1 (128.100.17.x), Building 2 (128.100.18.x), Building 3 (128.100.19.x), Building 4 (128.100.20.x), Building 5 (128.100.21.x), Building 6 (128.100.22.x), Building 7 (128.100.23.x), Building 8 (128.100.24.x), Building 9 (128.100.25.x), and Building 10 (128.100.26.x). Router IP’s will be respectively as follows: (128.100.254.11), (128.100.254.12), (128.100.254.13), (128.100.254.14), (128.100.254.15), (128.100.254.16), (128.100.254.17), (128.100.254.18),
Case Example A: Elaine has sued Jerry because Jerry fired her. Elaine was on the job for two months.The job offer letter that Jerry had sent her mentioned the great career opportunities at the company and stated that her annual salary would be $30,000. The company is an employment‐at‐will employer. Elaine was given no reason for the termination. After the termination, Jerry hired a man named Kramer, who had less job experience and education than Elaine, for the position. Elaine has sued to get her job back.
Ideally, each local office would integrate its computers with a LAN, so that all employees would be able to share information, and resources such as printers. In case there are multiple buildings in an office (like in the corporate office), each building would have its own LAN, and the LANs could be connected by a Backbone Network.

To add a data network to the remote building of range 500M the senior system engineer supported the fiber channel and another employee of the same organization suggested the ISCSI. Still there is discussion going on between these two networks I would like to fix the ISCSI to the remote building but, the fiber channel suggested by the employee is also not a bad idea but the price slightly varies.
