Question: Discuss About The Elman Network Intrusion Detection Algorithm? Answer: Introducation Telstra Corporation is a renowned organization in telecommunications as well as media in Australia. It is associated with developing and operating in telecommunication networks along with providing internet access, mobile and various other products as well as services for entertainment. The organization is considered as one of the largest company related to telecommunications. In the past few years, there has been a tremendous growth in their business and hence it has acquired a building in Perth, Australia to open a new office for expanding their network. There are various departments required for running the organization however only six departments will be accommodated in the new building. Hence, this report is focused on providing a suitable network design for the new office of Telstra Corporation to meet increasing demand of the organization. Further, the description of the IP addresses and subnets that will be allocated for the devices is also presented along with devices and c abling requirements. Network design and floor plan The network design for Telstra Corporation that has been presented below reflects that there are overall five floors in which the six departments will be accommodated. The floor plan has been prepared as such that sales and marketing department will be in first floor and the other departments will have independent floors for particular department. The network design illustrates that each floor will have a separate router connected to the central router in which ISP (Internet Service Provider) will provide internet access. Further, a wireless access point will be dedicated to each department in the building. The server room will be situated on fifth floor along with Information technology department. IP addresses and subnets A simple addressing solution will be followed for allocating IP addresses to the devices required for the organization. The solution for IP address allocation that has been designed for the network of Telstra Corporation is presented below: Major Network:10.0.0.0/23 Available IP addresses in major network:510 Number of IP addresses needed:230 Available IP addresses in allocated subnets:276 About56%of available major network address space is used About83%of subnetted network address space is used Subnet Name Needed Size Allocated Size Address Mask Dec Mask Assignable Range Broadcast Sales 60 62 10.0.0.0 /26 255.255.255.192 10.0.0.1 - 10.0.0.62 10.0.0.63 Information technology 50 62 10.0.0.64 /26 255.255.255.192 10.0.0.65 - 10.0.0.126 10.0.0.127 Marketing 50 62 10.0.0.128 /26 255.255.255.192 10.0.0.129 - 10.0.0.190 10.0.0.191 Research 30 30 10.0.0.192 /27 255.255.255.224 10.0.0.193 - 10.0.0.222 10.0.0.223 Accounting 25 30 10.0.0.224 /27 255.255.255.224 10.0.0.225 - 10.0.0.254 10.0.0.255 Dispatch 15 30 10.0.1.0 /27 255.255.255.224 10.0.1.1 - 10.0.1.30 10.0.1.31 The network has been designed such that it can accommodate around 510 hosts if there is increasing demand with growth in the business. It has been determined that presently there will be 230 workstations as hosts in the network. The IP address will be allocated to the devices by central router using DHCP (Dynamic Host Configuration Protocol). This means that automatic allocation of IP address will be carried out for devices in the network. The wireless access points will provide gateway to access the network through mobile devices so that guests are able to have the facility of Internet access. However, the accessibility to the network will be restricted according to the authorization level of users. Used devices and cable types The devices that will be used to set up the network infrastructure for Telstra Corporation along with the required types of cables are presented as below: Device Name Model Specification Router Cisco 2911 Integrated Services Router 3 integrated 10/100/1000 Ethernet ports (RJ-45 only) 4 enhanced high-speed WAN interface card slots 2 onboard digital signal processor (DSP) slots Switch Cisco 2960-X series switch PoE: Power over Ethernet LAN Base: Advanced Layer 2 Feature set IP Lite: Basic Layer 3 Feature set Server Cisco UCS C480 M5 Rack Server 2666-MHz DDR4 memory and 48 DIMM slots 12 PCI Express (PCIe) 3.0 slots 32 Small-Form-Factor (SFF) 2.5-inch, SAS, SATA, and PCIe NVMe disk drives Wireless access points Cisco RV130W WF wireless router 4-port switch Ethernet, Fast Ethernet, Gigabit Ethernet, IEEE 802.11b, IEEE 802.11g, IEEE 802.11n 825 Mbps 12000 IPSec VPN tunnels: 10 VPN tunnels: 10 Workstation Dell XPS 8500 Desktop CPU - Intel Core i7 (3rd Gen) 3770 / 3.4 GHz Max Turbo Speed - 3.9 GHz Technology - DDR3 SDRAM - non-ECC Memory Speed - 1600 MHz Installed Size 8 GB Laptops Apple MacBook Air Processor - 5th Gen Intel Core i5 RAM - 8 GB Disk Drive - 128 GB SSD Operating System - MacOS Sierra Cables Cat 6 cable Frequency - 250 MHz Return Loss (Min. at 100MHz) - 20.1 dB Characteristic Impedance - 100 ohms 15% Cost analysis The cost benefit analysis that has been calculated in context to the proposed network design for Telstra Corporation is illustrated below Criteria Costs Development Hardware $ 32,500.00 Software $ 1,250.00 Networking team salaries $ 9,650.00 Training $ 1,500.00 Total Development Cost $ 44,900.00 Operations Hardware $ 9,250.00 Software $ 350.00 Operational Labor $ 13,500.00 Total Operational Cost $ 23,100.00 Net Benefits Approximate salary savings $ 150,000.00 Reduced operating cost $ 50,000.00 Total Benefit $ 200,000.00 Discount Rate Used 4.00% The total benefit that will be achieved from implementing the proposed network design has been estimated as $ 200,000.00.
