There can be an assortment of devices on a network depending on the size. These devices need an effective method of communication between themselves in order to relay the information to the correct destination. The communication protocols are a set of standards that tell different hardware and software how to transfer data elements between them. When working with the OSI model, the protocols will govern communication between entities on the same reference model layer. Network protocols include mechanisms for devices to identify and make connections with each other, as well as formatting rules that specify how data is packaged into messages sent and received (Mitchell, 2014). If devices are using different protocols, they cannot understand each other in order to successfully transmit and receive data. Communication Protocols The network for Kudler Fine Foods is that of an Ethernet network. The bus topology used within each store supports fast Ethernet speeds of 100mbps. Each store also has VOIP phones that use Internet Protocol to communicate with the network. The servers and computer stations will communicate with the Ethernet line using the Transmission Control Protocol/Internet Protocol (TCP/IP). TCP/IP is a network standard that defines how data is sent throughout the network. TCP/IP consists of two different layers. Transmission Control Protocol is the higher layer and manages the assembling of a message or file into smaller packets. After forming the packets, the device will transmit them across the Internet and to be received by a device that is also using the TCP protocol. The device then reassembles the packets into the original message and presents the data to the user. The lower layer is Internet Protocol and handles the... ... middle of paper ... ...ues that are noted. The customers at Kudler Fine Foods will not want to wait until the systems are back up and running for them to purchase their goods. The customers may leave for another store and that is a loss of revenue. Using reliable performance metrics should prevent the network from causing negative impacting occurrences. Backup plans and up to date hardware and software should also be items that provide maximum performance for the network. Works Cited Davis, K. (2008). Latency and Jitter.

The owner of Kudler Fine Foods, Kathy Kudler, has watched her dream of owning and operating a grocery store that specializes in fine quality food grow within a short period of time. The success of Kudler Fine Foods can be attributed to the innovative ideas, effective leadership, and organizational structure. The overall mission of Kudler Fine Food's "is to provide our customers the finest in selected foodstuffs, wines, and related needs in an unparallel consumer environment. Our selections coupled with our experienced, helpful and knowledgeable staff, merge to offer each customer a delightful and pleasing shopping outing" (Apollo Group, 2003). Kudler has managed to maintain its mission statement by providing its customers with the best and as a result the company has flourished. "Kathy considers one of her key responsibilities to be that of identification of new gourmet items that can be offered in her stores (Apollo Group, 2003)." Therefore, Kathy is considering plans to contract with local growers of organic produce to yet obtain the best in quality products for her consumers and take her business to the next step. If Kathy makes the decision to contract with local growers then changes could be introduced into the company's overall structural organization. Each aspect of Kudler Fine Food's organizational structure from basic business process to the supply chain and quality control process will be affected by the formation of a contractual relationship with local organic growers.

There is a growing need it increase and standardize their network structure in the way of wired and wireless network. The network infrastructure has become a global on demand in all business. Technological advances require a responsive network infrastructure that is designed to control costs and reduce risks to a business, while enabling new business opportunities. The first Kudler's operations will have to be centrally linked tighter one server that can be accessed at all location. This will elevate the database which is presently used and has to be updated continuously at each store. The new system will accomplish the need to the entire operations. The heads of each location will be called upon for a meeting, the CEO, Kathy Kudler will have be aware of the global changes that will take place and effect the organization. Establishing a central database management system will keep track information from each facility and there location. Being able to access this information from any location can support the supply chain management system that Kudler is also looking for. The information in a database that can be linked to all three stores, this way the information of gathering these resources can be deploy and optimize the network infrastructure with proper management. With a system that can be integrated between these facilities can be all run virtually regardless of the complex organization's size, achieving business viability and maintain a competitive edge will be a paramount concern at Kindler's.

    Problem Statement: In 2003, Zara's CIO must decide whether to upgrade the retailer's IT infrastructure and capabilities. At the time of the case, the company relies on an out-of-date operating system for its store terminals and has no full-time network in place across stores. Despite these limitations, however, Zara's parent company, Inditex, has built an extraordinarily well-performing value chain that is by far the most responsive in the industry. Therefore the major problem to the company is to decide whether it has to upgrade the present system and by doing so, risking the reliability they have with the current system or to continue with the present DOS based system which will not be compatible for future changes or improvements.

    Ethernet is a household of processor interacting machineries for local area networks. Ethernet was brought to light in 1980 and consistent in 1983 as IEEE 802.3. Ethernet has basically substituted rival online local area network machineries such as token ring, FDDI, and ARCNET. The Ethernet ethics include some cabling and beckoning alternates of the OSI physical layer in use with Ethernet. The unique 10BASE5 Ethernet recycled coaxial cable as a collective medium. Well along the coaxial cables remained exchanged with twisted pair and fiber optic contacts in combination with hubs or switches. Figures rates stood sporadically increased from the innovative 10 megabits per second to 100 gigabits per second. Structures talking across Ethernet split a brook of info into smaller parts called frames. Each frame held basis and endpoint discourses and error-checking information so that dented data can be perceived and re-transferred. As per the OSI model Ethernet delivers amenities up to and counting the info connection layer. Meanwhile its profitable announcement, Ethernet has booked a great grade. Landscapes such as the 48-bit MAC statement and Ethernet frame arrangement have prejudiced other interacting protocols.

It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
