Network Design - Term Paper ExampleAdditionally, at the moment, the departments lack secure engagements and hence prone to patronage virus attacks. The director of the campus is seeking to improve security, raise network bandwidth, and also consolidate the multiple LANs into one campus network whilst keeping costs minimal. The major problems set in the current network include High rate of collisions Slow speed due to a large broadcast domain High administrative cost due to a lack of centralized network management Lack of backup WAN connectivity Lack of data backup on servers unequal network security Use of manually assigned IP addresses The campus building is 40 years and 2-storeyed. Its dimensions are as follows Length 240 Feet Width 95 Feet raising 30 Feet Workstation Placement Number of Workstations Users Total WS 6 Instructional computing machine labs 21 WS Student and Instructor 126 WS (based on 20 WS for students and 1 WS for instructor on each lab * 6 labs) Student Compu ter Lab 30 WS Student 30 WS 6 Offices 1 WS Staff 6 WS 1 assenting office 5 WS Staff 5 WS Library 10 WS Student 10 WS Library 5 WS Staff 5 WS 4 Instructional Classrooms 1 WS Instructor 4 WS Total Server ?

Netwo rk Address 10.15.0.0 Network Mask 255.255.0.0 At least 11 subnets are required, implying a privation for at least 31 addresses for each subnet. The closest number of addresses offered by a subnet is 32. Nonetheless, taking into consideration the fact that all subnets require a network address and a forecast address, 30 is the appropriate number of IP addresses. Given that the student computer lab requires a minimum of 31 addresses, 64-address subnet is required. Considering availableness of a whole class B network, constituting a Class A address and a class B mask, it is possible to anticipate growth on the devices used in each classroom / office and make use of a whole Class C network for every subnet. This will assign each subnet in 256 addresses whereby 0 would is to be the network address while 255 will be the broadcast address. This leaves 254-subnet IPs available for use. Proposed Subnets Range 6 Instructional Computer labs 10.15.0.0/24 Addresses 10.15.0.1 - 10.15.0.254 10.1 5.1.0/24 Addresses 10.15.1.1 - 10.15.1.254 10.15.2.0/24 Addresses 10.15.2.1 - 10.15.2.254 10.15.3.0/24 Addresses 10.15.3.1 - 10.15.3.254 Student Computer Lab 10.15.10.0/24 Addresses 10.15.10.1 - 10.15.10.254 Staff members in all offices 10.15.20.0/24 Addresses 10.15.20.1 - 10.15.20.254 Students in the library 10.15.30.0/24 Addresses 10.15.30.1 - 10.15.30.254 Instructors on the 5 lecture rooms 10.15.40.0/24 Addresses 10.15.40.1 - 10.15.40.254 Servers on first and second floor
