1. Requirement and Project Scope
1.1 Requirements: This Network Design Assignment considers the organization requirements and prepares a network design to suit these requirements. In addition to designing this report also focuses on developing a network configuration which involves configuration of routers and switches. This is followed by access point detailing and configuration of the server finalization. Post which an estimated budget is prepared for implementation of this network design.

1.2 Scope: In the next step the project prepares the complete network configuration based on network design prepared. As per this design IPv6 configuration will be provided to the branches A and B while IPv4 configuration will be provided to branch C. IPv6 configuration will also be applicable for headquarter branch. There is no flexibility to project budget, and it needs to be completed within this approval limit. Also, there can be no extension to the project timelines as this will result in expenses to resources. Hence increasing the budget.

2. Network Design and Justification

2.1 Network Design

2.2 IP Addressing Scheme (IPv6) for branches and headquarters

2.3 Network address for devices i.e. computers and servers

2.4 Choice Justification: For good effectiveness and efficiency of the network design, the routing protocol selected is Open Shortest Path First (OSPF) because it has various benefits to a network design. Starting with being a loop free protocol the time required for transferring changes to the entire autonomous system in the router is very minimum which improves the performance of the network. In addition to this benefit network overhead is also reduced by this protocol which means less interference for the network and hence effectiveness is better. The network security is also improved by this protocol as MD5 authentication is carried along with implementation of interface based plain text. This capability of the OSPF routing protocol ensures that it can handle a large scale of networks up to thousand units.

Due to a dual stack mechanism being applied in this network design which consists of IPv4 and IPv6 for different branches, the efficiency is improved. Both the branches A and B can easily communicate among themselves while branch C follows a different protocol IPv4. The dual mechanism context of IPv4 and IPv6 protocol has already been discussed earlier in the report.

Conclusion
Network design details and its implementation procedures have been illustrated in this Network Design Assignment for the given organization. Network configuration and device requirements have also been detailed. Owing to its various benefits, Open Shortest Path First (OSPF) has been selected for the network design. In order to maintain an effective and efficient communication network, the dual stack mechanism of IPv4 and IPv6 has been considered for all the three branches and the headquarters. Cost estimation has also been prepared considering the optimal number of resources required for the project completion. Considering the cost of team members, Consultant and the Project Manager the budget estimates is between $105,000 and $160,000. In addition, the timelines for project completion has also been estimated for this project and this comes out to an approximate of 63 days. The timeline estimate includes completion of all the activities which are part of this project and maintain the quality delivered for each of the activities so that the objective of maintaining a high effectiveness and efficient network design is achieved.

Abstract
At present, there are several publications that focused on the field of networking. Due to considerable rise in the areas like network designing, subnet, IP address, routing protocol, access control etc. helps in enhancing the effectiveness of networks. In this note, it can be stated that the first step of networking is to record the required information collected from the site of Ciox Health Melbourne. After that, the network design needs to be showed, and its activities should be demonstrated by considering the IP address. In the next step, the routing protocol and access control list need to be stated. Here, it can be mentioned that, before accessing control, the configuration of the switches and routers needs to be done. In the next step, host configuration, server and access points are provided. The last step considers the estimated timeline and budget required for the project followed by a conclusion.

Introduction
This Network Design assignment tries to shed light on the importance of the significant rise in the area of network designing, routing protocols, IP address, subnets, access control etc. to enhance the effectiveness of various networks exist in an organisation. This report considers Ciox Health Melbourne and focuses on network activities of the organisation. Collection of the information for the site can be regarded as the first step.

1. Identification of Project Scope and Requirements
1.1 Explaining the Project Scope
Presentation of network design, explanation of network operations and IP address are done. Discussion of routing protocol and access control is also an essential part, and it should be configured with switches and routers. After that configuration of the hosts, servers and access points are also needs to be taken into account. This report also considers the estimated timeline and budget.

1.2 Explaining the Project Requirements
The following are the essential requirements for the network set up of Ciox Health Melbourne.

2. Demonstrating the Network Design and providing Justification
2.1 Drawing the Logical network Design

Figure 1: Logical Design of Ciox Network

Justification: The above figure shows the network of Ciox Health. With the help of this logical network design, internet accessibility and reliability of the other two sites of Ciox Health can be easily explained. This figure also depicts that the customer platform is beneficial for Ciox Health to gain details information about the customers. In this note, it can be stated that the customer platform is considering the same server to arrange network configurations properly.

2.2 Tabular form of Suitable IP Address Scheme

Justification: From the above IP address table, it can be mentioned that subnet classifications are performing for the setting up the network properly. This table, with the help of CIDR mask and address spaces, also clearly shows that the CIDR IP address scheme, is used for the system. The key reason behind using this scheme is CIDR is considered as the form of classless addressing and which is more effective in comparison to classful IP addressing.

2.3 Mentioning Static and Dynamic Routing Protocols and Its Justification2.3.1 RIP, EIGRP, OSPF

Justification: Routing information protocol (RIP) is taken into consideration to ensure the communication between different network segments. To make sure about working of routing protocol, Ciox Health is using various Ip networks which are already registered.

2.3.2 Access Control List (ACL) commands

Above access control list (ACL) configuration can be applied on the router of Ciox HQ to avoid any unauthorised access of data by using the same portal.
