5.3 Design Phase IP address? Software hardware use?
Design phase is the most important and analytical phase. The network design is developed based on the technical and business requirements obtained from the planning phases. The network design specification is a comprehensive detailed design that meets current business and technical requirements. It provides high availability, reliability, security, scalability, and performance. The design includes physical, logical network diagrams and an equipment list. The project plan is updated with more specific and detailed information for implementation.

5.3.1 Network Topology Design
After everything have been detailed in the plan phase, I proceed to design them according to the paperwork or project plan. During this stage, I have design the topology for the new office which meet the requirement and criteria stated. Both physical and logical diagram are being created in this phase. The application or software that I used to design the topology is Creately.com and Packet Tracer 7.0. Creately.com is an online application that provides user to draw UML diagram, flowchart, network diagram and many more. The reason that I used this online application is it is free and easy to use instead of I need to draw by myself for the physical topology.

Designing the configuration such as protocol used, IP address, ACL, DHCP, Firewall and security configuration need to meet the network architecture specification. In order to perform a good configuration design, I need to list a possible common configuration and analysed it. This is because not all configuration are suitable with the network. Some of configuration need to be modified to meet the network specification. Lastly, I also have to study and do some research for the configuration so that it helps a lot during implementation phase. (letak gambar
