Question: Discuss about the Flowchart Maker and Diagramming Software. Answer: Introduction Network troubleshooting is a difficult task in IT infrastructure management. Having a detailed network diagram is a first and very important procedure in IT infrastructure management. Here how to have a detailed network diagram and how to split the entire network diagram into small segments are explained. This will be very helpful in troubleshooting any IT infrastructure failure error. Basics of Network diagram will be studied. Detailed network design will be studied with the help of detailed network diagram. Physical network design in each floor will studied with the help of relevant diagrams. Network designing software details will be studied briefly. Basic network troubleshooting procedure will be studied briefly. Any IT infrastructure will be having lot of devices ("Network design checklist: How to design a LAN", 2017) like computers, IP Phones, Printers. These devices will be connected with switches in LAN. All these switches will be connected with a main switch called core switch. This core switch will be connected with router. The router connects the entire LAN with outside WAN. Switch is a junction point that can connect multiple devices based on switching table. Router is a routing device that guides the data from one network to another network based on routing tables. All the devices are connected with each other using wireless media or wired media. 801.11n is the governing wireless technology. Ethernet is the governing wired technology. In wired technology each device will be having a NIC (Network Interface Card). LAN cables like Cat5, Cat5e, Cat6 connects the NICs of two devices. The ends of the cables are crimped with RJ-45 connectors. These connectors are used to plug in the cables into the NICs of the network devices. Each network device will be configured with IP address. IP address is a logical address. Each network device will be having host names. Human mind can understand and remember only host names well. DNS is the IT infrastructure service that maps the host names with corresponding IP addresses. Network design will be based on OSI layer system and TOP-Down approach will be used in the network design (Oppenheimer, 2011). Any network design will start with end user requirements. Detailed Network Diagram Troubleshooting network issue should be done in a phased manner ("Five Things to Be Considered in Designing a Network", 2017). Most of the universities, offices will be having multiple floors. Having a separate physical design in each floor will be very useful in a quick network troubleshooting. The following diagram shows the physical design of each floor. Microsoft Visio ("Flowchart Maker Diagramming Software, Microsoft Visio", 2017) is mainly used for drawing network design diagrams. The LAN design drawn in Microsoft Visio is attached below. Each network device will be configured with separate IP address ("Network Design Implementation | Network Planning | Systems Engineering", 2017). By referring the DNS server, the physical name of the network device can be found out. By referring the main network design diagram the location of the network device can be found out. By referring the corresponding floor network design diagram the faulty device will be found out. Suitable steps can be made to troubleshoot or replace the faulty device. Conclusion Basics of Network diagram are studied. Detailed network design is studied with the help of detailed network diagram. Physical network design in each floor is studied with the help of relevant diagrams. Network designing software details is studied briefly. Basic network troubleshooting procedure is studied briefly.
