...switches. You’re seeing an excessive number of broadcast packets throughout the LAN and want to decrease the effect this broadcast traffic has on your network. What steps must you take to achieve this goal? Ideally it’s preferable to probably split it up into one or more workstation subnets (based on say, departments) and then another subnet (or more for a larger enterprise) for the servers. Traffic between the subnets will be routed. This means the broadcasts from workstations won't hamper the servers and vice versa. Case Project 2-3 In Chapter 3, you learn about network topologies and technologies. As preparation, do Internet research on the following topics: ● Physical versus logical topology ● Bus topology ● Star topology ● Ring topology ● Ethernet and CSMA/CD Write a short explanation (two to three sentences) of each concept and be prepared to discuss it with the class.

...It will discuss nods, NICs, data routing devices, firewalls, and servers. Hardware choices are very important for a LAN. The types of devices on a network will determine its capabilities. The two biggest factors are cost vs. function. The person, or people, designing a LAN do not want to pay more than necessary according to their needs. But underestimating their requirements can be just as bad, or worse. Underestimating requirements can force a network designer(s) to have to completely replace some, or all, of the network...

...Ethernet cards are essential parts of a network. They connect a computer to another computer or to a server by using a cable, an alternative to a wireless network. Ethernet Network – The Role of Ethernet in Computer Networks An ethernet network is a situation in which multiple computers are connected to one another and share the same Internet protocol address. An ethernet network has multiple computers on the same server. The benefit in this is that multiple networks do not need to be created. The downside to an ethernet network is that the connection of multiple computers leaves each computer open to hacking, malware, and viruses — in the event that a virus should attack one computer on the system. There are certain components necessary for an ethernet network: * Ethernet cable * Ethernet hub * Crossover cable * Router Ethernet Cable An ethernet cable is a necessary cord to connect two or more computers to the same network. Each computer must have its own ethernet cable in order to operate on the same ethernet network. Ethernet Hub An ethernet hub is a device used to string together each ethernet cable, which connects each computer on the same network. An ethernet hub contains several ethernet ports. Crossover Cable A crossover cable is a substitute for ethernet cables when one wants to connect two or more computers to the same ethernet network. Router A router is similar to an ethernet cable in that it connects two or more devices. Routers are more often used for...

...Slower devices would still work on the faster network, but only at the fastest speed that device can work at. For an organization of 100 users, upgrading to a 1000 Mbps network would be an unnecessary expense. In regards to internet connections, the network would only work as fast as the internet service provider allows, or the speed that the organization is paying for Physical and Virtual Local Area Networks In a physical local area network (LAN) all devices are connected physically on the same network to each other, sharing a broadcast domain, therefore having a limitation due to transmission mediums and speeds. To separate devices on a separate networks, routers and firewalls would need to be used for each network separation. Spacing and location of devices will determine the type of devices and where these devices will be placed. Physical LANs can range from wide area networks (WAN), to campus area networks (CANs), or metropolitan area network, based on the size the network is to encompass. Logical topologies, such as virtual LANs (VLANs) is the signal flow of devices without regards to the physical topology of the network. The University of Houston (2016) explains how an organization can save funds by purchasing one switch as opposed to multiple switches, as one switch can be configured to host multiple VLANs. Further more they go on to explain how trunking allows ports on multiple switches to be viewed as one VLAN. Hubs and Switches Both hubs and switches connect devices...

...Team B - Integrative Network Design Project Jacob Acuna, Susan Granata, David Teague University of Phoenix - NTC/362 Ronald Bowell October 26, 2015 Page Break Kudler Fine Foods is a purveyor of specialty and gourmet foods in the San Diego, CA. area. They currently have three locations: the home office in La Jolla, CA., and two store locations in Del Mar, CA. and Encinitas, CA. Kudler is in need of a new network design and topology that will address multiple issues faced in a growing enterprise. The new network must incorporate a new network topology to reduce downtime and ensure that functionality will remain if one or two devices are down. In addition, a VoIP system must be installed over the network, along with an internal WLAN in each store. The WAN will tie all three stores together to increase collaboration and network file sharing, and the new network must be easily scalable to support growth of the company and integration of future stores. Of utmost priority is the security of the network. The sensitive nature of credit card processing makes Kudler Fine Foods a prime victim for cyber threats, and therefore policies must be put in place to protect the customer and employee data. Network Characteristics and Components The current network characteristics and components for the Del Mar store starts with a small office scenario that is accompanied by six Dell Vostro computers for management. All six computers are running Windows 7 and all...

...from damage when adequately routed physically, but some cables will be routed next to or under manufacturing equipment. o The network should use the same topology and media throughout to minimise the number and variety of spares that must be kept on hand. o The office space is expected to have an open plan, and the office partitions are designed to facilitate routing physical network cables. o The budget allocated allows for the purchase of new cabling and connection hardware, including network adapters, as necessary. However, you have been directed to keep costs as low as possible. o The company wants to install a network with a minimum bandwidth of at least 100 Mbps. o The plan should allow for future expansion and for eventually taking the bandwidth to 1 GB per second. o The final network should not have any routing requirements. With all of the criteria mentioned, the major concerns are the electromagnetic interference from the manufacturing space and the protection of the cables with the effective speed. These concerns will be addressed in the later research of this project. [5 marks] • All work by others should be properly cited using the IEEE style of referencing.

Hypertext Transfer Protocol (HTTP) is used for transfer of multimedia files, video, sound, and text over the internet. Kudler Fine Foods will implement File Transfer Protocol (FTP) to download files, transfer files, delete files, copy and rename files from the internet as needed. Mesh Protocol will be used to connect all devices such as printers, computers, and scanners on the network. In a true mesh topology every node has a connection to every other node in the network ("Common Physical Network Topologies ", 2014). The network will consist of a hardware firewall blocking unwanted access from outside of the location. The next step is to set up a hub or switch that will connect all of the stores terminals. All of these terminals such as registers and remote locations such as warehouse will be hardwired with twisted pair CAT 5 Ethernet cable. The server will be located in a room in each store with the hub or switch. A wireless access point/router will be centrally located in the store to provide good signal in every part of the store for employees using their handheld devices to be able to view and update the store inventory while on the sales floor Since the blade servers are easily...

...Resilient Packet Ring Technology 1 CHAPTER 1 INTRODUCTION 1.1 Background: The nature of the public network has changed. Demand for Internet Protocol (IP) data is growing at a compound annual rate of between 100% and 800%1, while voice demand remains stable. What was once a predominantly circuit switched network handling mainly circuit switched voice traffic has become a circuit-switched network handling mainly IP data. Because the nature of the traffic is not well matched to the underlying technology, this network is proving very costly to scale. User spending has not increased proportionally to the rate of bandwidth increase, and carrier revenue growth is stuck at the lower end of 10% to 20% per year. The result is that carriers are building themselves out of business. Over the last 10 years, as data traffic has grown both in importance and volume, technologies such as frame relay, ATM, and Point-to-Point Protocol (PPP) have been developed to force fit data onto the circuit network. While these protocols provided virtual connections-a useful approach for many services-they have proven too inefficient, costly and complex to scale to the levels necessary to satisfy the insatiable demand for data services. More recently, Gigabit Ethernet (GigE) has been adopted by many network service providers as a way to network user data without the burden of SONET/SDH and ATM. GigE has shortcomings when applied in carrier networks were recognized and for these problems, a technology...

...Priscilla Oppenheimer, an instructional text detailing a method of network design that’s based upon what can be readily found evident throughout the overall networking community to be the most logical and efficient sequence of steps necessary in the creation of a network. Having stated this, it is of value for the reader to know that the aforementioned sequence of steps, as examined in Oppenheimer’s work, will correspond closely to the order of WLAN design and management issues that are addressed in this document, and can be followed up by way of documentation found under the same title and author at the end of this article. The major design and management issues found unique to a WLAN involve those pertaining specifically to the transmission and reception of radio frequency (RF) waves. For example, there is the strategic placement of access points (AP), which are devices designed to send and receive radio signals between nodes. This, in turn leads to a consideration of any possibility of physical materials that may be found that could hinder radio signals between APs, which will here be replaced by a ‘worst case’ factoring. Protocols and standards dealing with wireless technology are also unique, as they correlate directly to WLANcharacteristics. In support of wireless communications, physical wiring is also necessary, as the WLAN must at some point connect to a WAN....

...An Extended Entity-Relationship Model for Geographic Applications * Thanasis Hadzilacos Computer Technology Institute, University of Patras Box 1122, GR-26110, Patras, Greece thh@cti.gr Nectaria Tryfona National Center for Geographic Information and Analysis Univ. of Maine, Orono, ME 04469-5711, U.S.A nectaria@spatial.maine.edu Abstract. A special-purpose extension of the EntityRelationship model for the needs of conceptual modeling of geographic applications, called the Geo-ER Model, is presented. Handling properties associated to objects not because of the objects’ nature but because of the objects’ position, calls for dealing -at the semantic modeling levelwith space, location and dimensionality of objects, spatial relationships, space-depending attributes, and scale and generalization of representations. In order to accomplish this in the framework of ER and its derivatives, we introduce special entity sets, relationships, and add new constructs. The rationale as well as examples of usage of the Geo-ER model from actual projects are presented. 1. Introduction Is everybody special or are we all alike? Should we develop applications according to a special methodology for each class of applications, such as medical, business process and geographic, or should we use a single blanket approach for all? Personal preferences and philosophical discussions aside, it does seem that the general purpose side has won most battles in computer science, from hardware to programming languages...
