5. Now that you have reviewed the characteristics, positives, and negatives of Alan's proposal:
a. Write an alternative proposal that does not exhibit the same issues. The proposal should contain both a network design and a network implementation section, and correct the issues you listed in 1a.
Issues listed in 1a:
Alan’s plan to engage every employee about their needs is very time-consuming and unnecessary. Instead, Alan should contact team leads, directors, and executive leadership to gather this information and make an informed decision. Alan also suggests using the cheapest possible vendor; this may lead to issues with poor quality of service, poor hardware quality, a lack of compliance with standards, software which lacks a good UI for engineers to utilize. He may not also be taking into account these bid requests containing proper number of licenses, training of employees on the hardware, installation, implementation, and deployment of new environment, into the figures for final cost. Alan’s proposal of setting up WAP only in areas where groups have requested it, may lead to issues later with collaborative work spaces and efforts when users with only wireless capabilities cannot work with those in spaces with purely LAN environments and vice versa.
b. Explain specifically why your proposal is better than Alan's, hitting on all of the following topics in your comparison: Speed Cost, Network management, Security, Functionality
SCENARIO
Spidola, an organization that manufactures radios, uses many local area networks in its corporate office. Spidola naturally used earlier forms of Ethernet based on hubs when LANs were first becoming popular. The LAN speeds in the corporate office have been upgraded several times over the years, with some groups now using 10 Mbps, and others 100 Mbps. Spidola continues to use hubs to this day, because the network manager, Alan, likes that the price of hubs is significantly lower than that of layer-2 switches, and feels that older technologies are time-tested and proven. The cables for the 100Mbps subnets run to a server room, while the cables for the 10Mbps subnets run to utility closets. Spidola has no wireless access.
The CTO, recognizing the current trends, has asked Alan to upgrade the speed of the network, use more modern technology, and add wireless capabilities. Alan submitted the following proposal.
Network Design
The network staff will interview the managers and technical leads from every internal group to determine what applications they use, and be sure to include the executives in this interview process. Using this information, the network staff will carefully calculate the speeds needed by each group. The staff will then contact various vendors to review their prices through discount negotiations or bid requests, and determine the cheapest devices available to support the speeds necessary for each group. The goal is to minimize purchase cost. This process will take about a year. During the interview process, the staff will also ask about who needs wireless access, to get a rough number of users that would use it.
Network Implementation
After the technologies and speeds have been designed, some groups will be given 100Mbps speed subnets connected to hubs, which will be placed in the server room. This allows some existing hubs to be reused rather than purchase. Some groups will be given 1Gbps subnets connected to switches, also placed in the server room. If most in a group needs wireless access, their wired access will be removed to save upgrade cost, and all in the group will access the network wirelessly. Wireless access points will be placed near to groups that need wireless access. If no one needs wireless access in a certain part of the building, no access point will be added. Access points will also be placed around the edges of the building, so that employees can access the network with their laptop at the picnic tables and outdoor areas. The upgrades will be rolled out one small area at a time, to avoid work disruptions. This process will take about 10 months.
Explanation / Answer
Alan's trying to reduce the cost gor that he is using old technologies and Alan also suggests using the cheapest possible vendor this may lead to issues with poor quality of service.
If we are not aware of new technoligies and networking concepts we will face alot of problems
we have to use higher speed networks lans are used in large area networks where switches are used in between the lans in present days wireless networking is much easier. and at sometimes we need to upgrade all the things in network that we are using.
if wireless connectivity is there we can use the internet and can access the laptop through virtual private network. it will reduce our burden and stress. in other words it will reduce the cost effectiveness.and the routers will be good enough to use.
wireless application protocol we can access it over the mobiles but it wont suitable for all. most of the people are using wireless network. it is easy to access. in organisations there are large area networks and wide area networks to connect.
