Network Design - Term Paper Example Additionally, at the moment, the departments lack secure networks and hence prone to frequent 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 identified 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 Inadequate 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 Height: 30 Feet Workstation Placement Number of Workstations Users Total WS 6 Instructional Computer 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 Computer Lab 30 WS Student 30 WS 6 Offices 1 WS Staff 6 WS 1 Admission 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 ?

Instructional To be determined by student Definition of the subnet The following subnets are adopted in the design: Each lab is to have a subnet, totaling to 6 subnets The student computer lab is to be assigned a subnet of its own Staff members in all the offices will be assigned a subnet Students in the library will be assigned a subnet One subnet will be assigned to the instructors in the lecture rooms The two servers, one of the first floor and the other in the second floor will share a subnet Definition of the network address, subnet mask, and available IP addresses to be used by the computers or devices. Network Address: 10.15.0.0 Network Mask: 255.255.0.0 At le ast 11 subnets are required, implying a need 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 availability 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 allocate 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 10.15.1.0/24 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 Instructor’s 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
