PowerPoint Presentation Team-A NTC/360

Introduction : 

Introduction Welcome to Team-A presentation our goal is to identify the current situation for Huffman’s locations. In addition to this declaration, our team are attentively reviewing the advantage and disadvantage of the current IT equipment, and will be included in this presentation.

Overview I. : 

Overview I. Existing telephone network Advantages and disadvantages of the phone network Recommendations of a new telephone network Existing data network Advantages and disadvantages of data networks Recommendations and benefits of a new data network

Overview II. : 

Overview II. Existing network protocols Advantages and disadvantages of network protocols Recommendations and benefits of new network protocols Existing topologies Advantages and disadvantages of topologies Recommendations and benefits of new topologies Existing switching technologies

Overview III. : 

Overview III. Existing telephone network Advantages and disadvantages of switching technologies Recommendations and benefits of new switching technology Current security system Identifying security needs Advantages and disadvantages of security approaches Recommendations and benefits of new security approaches

The existing telephone network : 

The existing telephone network PBS/Pots system VOIP Nortel IP phone system

Advantages and disadvantages of the telephone network : 

Advantages and disadvantages of the telephone network Outdated telephone network cannot serve 1400 users day-to-day Cannot support present system and even future growth Congestion between PBX/POTS and VOIP systems Nortel IP phones are inefficient

Recommendations of a new telephone network : 

Recommendations of a new telephone network Upgrading telephone network systems New VoIP services must be set up Wireless networking will be implemented where wired connections are unavailable Avaya 9600 Series IP Desk phones Replacing the current PBX/POTS Each employee will have voice mailbox for simplified messaging services and caller ID.

Existing data network : 

Existing data network Outdated data network Cisco 10Mb Hub Cisco 2600 router Fractional TI AOL modem Internet

Advantages and disadvantages of the data network : 

Advantages and disadvantages of the data network Data network cannot facilitate 1400 employees Not enough bandwidth Routers wireless coverage is limited Outdated network interface cards

Recommendations and benefits of a new data network : 

Recommendations and benefits of a new data network Should be dedicated T1 trunk lines to each location Adding additional bandwidth Installing leased T1 trunk lines Upgrading all offices to Cisco 3900 Series Integrated Services routers Rewiring for Ethernet technology using CAT5 cabling Upgrading to Cisco Aironet 3500

Existing network protocols : 

Existing network protocols VOIP IP/SPX protocols

Advantages and disadvantages of network protocols : 

Advantages and disadvantages of network protocols TCP/IP protocol provides faster and reliable connections than the presently used VoIP has the advantage of providing low cost local and long distance phone service Network faults can cause loss of data Network errors can lead to loss of resources(Unknown)

Recommendations and benefits of new network protocols : 

Recommendations and benefits of new network protocols Current IP/SPX protocols would be eliminated and changed to the TCP/IP protocols Use the IPSec support in Windows Vista and Windows Server 2008 to protect IPv6 traffic(Davies, 2008)

Existing topologies : 

Existing topologies Bus topology Star topology Token ring topology

Advantages and disadvantages of topologies : 

Advantages and disadvantages of topologies The Bus topology is cost effective Difficult to maintain and repair in case of technical issues The Token ring topology is one of the best recommendation, because the connected nodes are able to function independently in case of cabling breakage

Recommendations and benefits of new topologies : 

Recommendations and benefits of new topologies The network systems will be based upon the four fundamentals of topologies that are Mesh, ring, bus, and star. The system includes their combination for the advantage of the establishment Flexibility and cost reduction are considered an extremely important (Raza & Turner, 2002)

Existing switching technologies : 

Existing switching technologies Cisco Catalyst 4900M Series Switch Cisco Catalyst 2960 Series Switch

Advantages and disadvantages of switching technologies : 

Advantages and disadvantages of switching technologies The Network switch in most Ethernet Local Area Network has vital element Intelligent device that can make use and several manage linked switches The price of ports ratio is inexpensive The switch is not good as the router when there are limitation of airflow The security attacks, spoofing and, unearthly procedures are prevalent if packets are misaligned

Recommendations and benefits of new switching technology : 

Recommendations and benefits of new switching technology Cisco Catalyst 4900M Series Switch, which will control data flow between all systems Wired equipment within each plant will be connected through the Cisco Catalyst 2960 Series Switch Bus topology will be integrated into new system To upgrade the network, computers, printers, and software Token-ring topology network will be tied into the new system with upgraded network interface cards

Current security system : 

Current security system The unsafe code can cause vulnerability to the databases. The current security system is too vulnerable that the attacks can easily penetrate the networking system Vulnerability is prevalent when the significant blocking defense are not implemented such as; firewalls, intrusion prevention systems and anti- malware products (Robinson, 2010)

Identifying security needs : 

Identifying security needs Wireless network has to be protected through encryption standards especially for the virtual private networks Traffic between the two LANs and WLANs should not be allowed in a trusted environment The internal firewalls is significant between LANs and WLANs

Advantages and disadvantages of security approaches : 

Advantages and disadvantages of security approaches Maintains the data integrity throughout the network Keeps away hackers Needs to invest money Only authorized person can access valuable and secured data

Recommendations and benefits of new security approaches : 

Recommendations and benefits of new security approaches Replacing computers to a new one the security for networking will be on a higher level Appropriate password and user name will be generated Appropriate network security will be set up
