Propose of RFP:
The reason for this proposal is to provide a company looking to update and expand its voice and data infrastructure. The company would like to possibly implement IPv6 into its network infrastructure. This proposal describes the requirements, constraints, and objectives of implementing IPv6.
Background Information:
The company is looking to expand its branch office as growth has permitted, but also would like a network that is scalable, reliable, and fast. They currently have 4 offices located throughout California area and would like to add 6 more branches to their network. None of the devices in any of there offices are currently connected to each other. The goal is to have these devices connected to where they share data seamless in a secure manor. The problem with the current network is mainly in the headquarter office with the 10base2 cabling hindering upgrades for voice and data project. The company would like the network infrastructure to resemble its current offices in respective cities. The goal is to connect all of the company offices together.
Requirements:
To upgrade the company network and data to modern day standards, in order to do this our comany must..
1. Analysis current network to determine the network equipment needed to preform the upgrade.
a. Must support current staff in each branch office
b. Need to determine IEE standard networking design and protocols used.
c. Need to be in transition from IPv4 to IPv6 protocol.
d. Must meet current industry standards.
2. Determine feasible and simple solutions to update the current network infrastructure.
a. A new ISP contract must be made to support business bandwidth utilization.
b. Install new VOIP PoE to different branch offices according to the number of workstations being utilized.
c. Will upgrade headquarters in San Francisco 10base2 cabling.
d. Every office will be connected to each other in a secure way.
3. Analyze the current network to research different enterprise wireless adaptors and access points to provide a variety of wireless solutions and security options to the organization. This will in turn increasing network and company performance.
4. Determine the security options needed to secure the edge of the network including the distribution level.
Network Architecture:
I will be using a hierarchical model because this network architecture minimizes costs. The appropriate internetworking devices for each layer of the hierarchy, thus avoiding spending money on unnecessary equipment for a layer. The convenance of having each layer segmented into functional networks allows for easy future expansions and provide more accuracy in the network. The privileges can be distributed to the different layers of the network management to control management cost. These layers keep the design simple and easy to read. Implementing this kind of network architecture will reduces the need for extensive training by keeping things simple. When it is time for testing a network design it is performed with easy because there is clear functionality at each layer. Within the different Branches I will be implementing the star topology network. For the additional branches our company will follow the structure cable standards set by TTA/EIA joint 568 Commercial Building Wiring when constructing the network infrastructure. The benefits of using both these design for the branch network and organization network is listed below.
Hierarchical Model:
a. Easy to design and implement
b. Clear organizational boundaries that separate segments of a network
c. Allows for traffic multiplexing meaning data can travel over the same network at the same time given proper routing equipment.
d. Allow organization to save on cost due to a company being able to clearly define their core needs to enhance or maintain organization IT performance.
Star Topology:
a. It is high-performing and data collision is nearly nonexistence.
b. Coast effective due to each
c. Installation is simplified and not complex to manage.
d. Provides fault tolerance by allowing one devices to go offline without disrupting the network.
IPV4 AND IPV6:
IPv4 is the most widely used ip addressing scheme now due to the industry slow transition. IPv4 can not read IPv6 packets and vice verse instead it needs to be encapsulated and sent across the network to the host which is called 6to4. The process requires special equipment such as a router with IPv6 capabilities. We will be implementing IPv6 by way of the transition process.
IPv6 Benefits:
· More Efficient Routing
· More efficient packet processing
· Directed Data Flows
· Simplified network configuration
· Security
WIRELESS TECHNOLOGIES
The main communication method for this network are LAN, WLAN and VoIP network. The wireless LAN will be connected by Cat6e UTP cabling. The 802. 11ac WLAN is made up of 2 AP’s and is connected to a separated switches in the main branch office. Headquarters will have 2 switches, 1 router and firewall because they have more departments that need to communicate with each other. Headquarters will have the most AP’s because it has more devices than any other branch. For all of the other offices operating in respective cities will only have 1 AP installed along with 1 switch and a firewall that route traffic to other departments within the organization. 802.11ac is being selected because it can roll back to previous versions making it the best choice because the old workstations in headquarters is configured for the older versions.
VPNs will be configured at the core layer will give the wireless network extra security. Access points create this type of protection by contain the Wi-Fi network access to individuals within the organization and this ensure the WIFI SSID not being broadcast outside the building. You could also disable the SSID, but this will not keep someone from snipping the company’s data being sent across the network, but a VPN will. Having data traffic from the AP’s travel through the VPN means that not just anyone can connect to the AP and data will also be transferred securely whereas this would not be the case if I just use 802.11ac by itself. We will be encrypting the devices with WPA3.
SECURITY TECHNOLOGIES
Our company will be installing a file share server in the main branch office so the organization can securely share data. At the Core layer there will be Sonic Wall firewalls put in place to protect the network. The network will utilize different protocols to monitor and manage traffic examples are SNMP on the layer 3 switches or routers. The SFTP server uses the SFTP transport protocol, which is an extension of the Secure Shell (SSH) cryptographic protocol. This will allow sensitive data to be share securely throughout the organization. The SonicWALL firewall put in place includes several benefits such as varies interfaces and throughput. Its unified threat management (UTM) feature that acts as an IPS. The UTM feature also includes malware and virus protection. Some of these features requires subscription can cost upwards to $800 annually.
Equipment Required :
· 7 Catalyst Switch
· Fiber Optic cable will be provided and installed by ISP
· 1 SFTP Server
· 1 Server
· Cat6e UTP cables
· 10 Access Points
· 1 Routers
· 9 Firewall
The hardest part of this project was writing the report. I have a hard time trying to articulate what I am trying to say or think, and it makes it hard for me to describe what things do. I also should have allowed myself more time to figure out a way to incorporate a T1 or T3 line in my project for WAN purposes.
