Question: Prepare a report to propose a network design for the selected organization

1. Discuss the geographical scope of the network with the support of diagram and explain the network backbone devices and a categorization various network segments, users, and applications.

2. Develop a logical design diagram for the Sydney branch based on three-layers hierarchal model (Core, Distributed and Access layers). The network should include in detail the set of required network devices and servers, with the justification.

3. Identify the type of IP addresses with the subnet masks that can be used for the Sydney branch for the client and servers.

Solution

Network Logical Design

1. Enterprise Campus - This module will help all function works independent within Sydney campus. In this module we not define any function for remote connection

2. Enterprise Edge - This module is related to communication that will provide communication between Enterprise Campus and remote locations as well as internet remote employees ,partners

3. Service Provider Edge - This module is related to WANs and internet service providers that area not implemented by the organization..

Each of this functional areas contains network modules, which in turn can include the core, distribution, and access layer functionality.

SYDNEY Office Infrastructure Module

We are design the Sydney office according to requirement

The Office infrastructure module helps to connects device within enterprise module and Data Center. The Office Infrastructure modules is contain three layer Access ,Distribution and Core Layer.

Access Layer
The Access layer, located within a campus building, aggregates end users from different workgroups and provides uplinks to the Building Distribution layer.This layer helping to provides the network services such as broadcast suppression, IP multicast , QoS and protocol filtering. This layer is related to access the network by authorized user . This layer take care about the unauthorized not access the network. This layer is contain all the network devices such as workstation, etc , and contain all end-user devices; that are responsible for access the network

Distribution Layer
The Distribution layer responsible for access between workgroups and to the Core. Routing implementation includes in this layer . We will add the filters or access lists therefore layer will controls access to services. Our planning , in this layer we will include the Redundant switches and redundant links to both the access and backbone is also implement .Hence if any routers or links will be down that will not affect the network serviceThis layer is related to contain the all devices, would be allows office users accessing the building network

Core Layer

Our planning , This layer implementation will help to high speed connection between the distribution ,access layer and the data Server, Edge distribution. According to planning is network would be highly available and reliable backbone therefore we will implements Redundancy, that ensure all.

Data Center Module
We propose, in data center will contain the SYDNEY Internal servers . These server will provide the all network services including email, file and print servers. For this layer need to implements the Redundancy in this layer and core too ; therefore authorization of server access will available for authorized user.

Edge Distribution Module
The Edge Distribution in our suggested network proposal is not compulsory . This is optional for our suggested model.

This model prevent from outer attack the network.This modules working is boundary between the Enterprise Campus and Enterprise Edge.This will provide security and prevent from threats between Enterprise Campus and Enterprise Edge. The Enterprise distribution model provide security from given threats. The Enterprise distribution given threats are given below

1. IP spoofing
2. Unauthorized access.
3. Network reconnaissance
4. Packet sniffers

This Enterprise distribution will provide a secure shield to the network ;therefore our data will be more secure. The IP address will be not access by unauthorized . The user and devices will be more secure and prevent .

Enterprise Edge Internet Connectivity Module

This modules working is be related to internet connectivity to internal userThe modules functionality is to providing the Internet services, such as HTTP, FTP, Simple Mail Transfer Protocol (SMTP), and DNS to internal user . This module responsible to Internet users with access to information published on an enterprise's public servers.The modules functionality depend on devices such as DNS servers, public servers (FTP and HTTP), DMZ, firewalls, and edge routers. The main component modules used in the Internet Connectivity module include the given below
1. SMTP mail servers
2. DNS servers
3. DMZ
4. Public servers
5. Firewalls:
6. Edge routers

WAN and Site-to-Site VPN Module

This module or function is responsible for reliable WAN connectivity. This will be providing the reliable WAN connectivity to the office.This module functionality will be based on in traditional , circuit switched and advanced media. For the purpose of redundancy security backup WAN link with site-to-site IPsec , we will be add VPN adds .We research on various option for related to connection ; Our recommendation is according to case study scenario company office will require more bandwidth . Hence T1 Frame Relay at the remote rooms into T3 at the main organization building suggestion is best. This will provides the office more bandwidthwith a good SLA . This approach implementation is cost effective too.In this project plan, our proposal is use is to use private addresses for the Sydney campus network. The private addressing is best policy since 1996 The best and traditional private addresses is Class C network type ; therefore office would be release eight of the Class C networks to the ISP, retaining two for ISP connectivity. With private addresses, the office will choose to use 198.16.0.0/16 for private addressing. The addressing scheme provides sufficient address space for each network and is recommend for using a highspeed Layer 3 switch for the building LANs. They can use the router for Internet and WAN access.

IP Scheme Proposal and Subnet Masking

TheProjectwillusing routing protocol that supports variable length subnet mask (VLSM) like RIP version or Enhanced Interior Gateway Routing Protocol (EIGRP) it is recommended to use two access points on each floor for redundancy then use layer 3 switches to provide high-speed switching betweenLANs..We are using Class C type network and need to consider about IP address will not waste . Since we would be breakup large network address into smaller network; therefore this is an efficient way as network traffic will reduce and simplify.

The subnet masking help into reduce the congestion of network , improve the network speed and performance of our propose system will be increase. This will boost network security.The system administration will be easy due to network subnetting and easy to control of network growth.
