Network Design: Subnets, Routers, and Wireless Access Points

This assignment provides a comprehensive network design, starting with subnetting a given IP address range for various geographical locations, including Seoul, Hong Kong, and Seattle, and detailing the assignment of IP addresses, subnet masks, and DHCP ranges. The document then analyzes router configurations, including interface assignments and IP addresses. Furthermore, it explores wireless technologies, such as Tri-Band, Beam forming, and NETGEAR ProSAFE, and discusses Cisco WAP131 features and specifications. The assignment also covers the benefits of cloud computing, Wyse Thin Clients, and VDI solutions, including cost savings and improved security. Finally, the document includes a weighted decision matrix for evaluating alternatives and a TCO calculator for Wyse Thin Clients, providing a holistic view of network design and its related technologies.

Weighted decision matrix
The weighted decision matrix (WDM) is a component utilized to discuss alternatives with
recognize to various criteria of more than one levels of importance. It will be utilized to mark
each other alternatives relevant to cannot changed reference and thus construct a half order of the
alternatives.
TRI-BAND
 Tri-band technology with smart connect bandwidth prioritization is designed mainly for
mobile device for domestic purpose.
 The Tri-Band has smart Wi-Fi Routers and Servers that is AC3200 offers outstandingly
speed till to 3.2 Gbps and router of dual-band speed should be doubled.
 The Smart Connect technology orders the traffic through two Wi-Fi with the range 5 GHz
to all devices to sustain the promising speed.
 Applications of High-Bandwidth are directed to 5 GHz with fast speed bands and the
Lower-Bandwidth routed to 2.4GHz band.
High-performance antennas for reaching maximum coverage
 Tri-Band Smart wireless router AC3200 has three external antennas that is adjustable and
three internal antennas that is fixed that gives the data with powerful streams to the
devices and it ensures full coverage for the house (Bloor, 2010).
 This also creates to customize the wireless router and has three antennas that is
replaceable and adjustable.

 The AC3200 is powered by the CPU (dual-core 1 GHz) and a total of penta-core
processer with 2.96GHz with 3 integrating co-processor power.
 This means AC3200 has handling capacity of multiple data streams with high speed and
the fast delivering process to more devices without weakening the speed and performance
of individual devices (2010 IEEE International Conference on Cloud Computing, 2010)
Beam forming
 Beam forming technology in AC3200 is concentrates the device received the wireless
signals and sends the Wi-Fi in a common direction (Babcock, 2010).
 This increases the efficiency of the network and it expand the range of the network.

Beam forming will use to increase wireless bandwidth and it will improve a wireless
network’s rank. It will improve video streaming, voice range and another bandwidth with sensitive
transmissions.
Devices that encourage beam forming target their signals facing every customer, focusing the
information transformation hence that more than one data success the focused device rather than of
radiating out into the atmosphere. NETGEAR
The NETGEAR ProSAFE is a 24-Port which has Gigabit Smart Managed alone with a Switch.
Features of NETGEAR (Buckley, 2010)
1. This has higher performance
2. Reliability
3. Easy management
This is managed through graphical user interface (GUI) or with the help of Smart Control
Center.
1. VLAN supports for the segmentation in traffic
7

2. For the bandwidth allocation, the rate gets limited (Furht and Escalante, 2010).
3. The prevention measure from Auto-Denial of service, so called DoS.
4. Prevention of Loop and control the storm of broadcast.
5. Performing port mirroring for monitoring the network.
6. For multicast optimization, IGMP snooping is used.
7. Link aggregation in addition with jumbo support framework.
Cisco WAP131
Highlights
It provides cost-effective 802.11n for connectivity. The range starts from 2.4-GHz and 5GHz
The single point of power over Ethernet is for connecting to its appropriate switch.
The port of PD permits to access the point powered by the backbone switch (Jhingran, 2010).
The work right out of box with easier steps of installation with simple web based techniques.
The overview of product
In the present world, the dynamic business environment with more number of employees are
now having more collaboration than ever (Shroff, 2010).
For the purpose of staying protective, the products are dependable, the business classes helps in
accessing the network applications all around the work area. The cisco WAP provides cost
effective way for extending the security, the higher performance on mobile networking. This is
done to the employees and the guests. This is because they can understand that they are
connected anywhere. The flexible way of connecting dozens of employees. The scale is to
accommodate the additional number of users and then they change the business needs (Crovella,
2010).
WAP131- is Cisco Wireless N dual Radio Access. This uses concurrent bands radios for the
improvement coverage and the capacity of users.
The cisco WAP 131 Wireless N dual Radio Access. It is mainly to get the process run in minutes
(SearchNetworking, 2018).

that, it has maximum coverage.
The single gigabit Ethernet LAN with interface that enables high speed uplink to the wired
network system.
Robust in security feature that includes WPA2, with RADIUS and secure way of authentication.

The simple way of installing the initiative web based configuration techniques enable up the fast,
the simple deployment technique.
The desktop design with integrating the stand, for easy access and the placement.
The intelligent system with Quality of Service(QoS) makes the network traffic the first and helps
in keeping up the critical network applications run in better way.
Power saving in sleep mode with port control helps in maximizing the energy and its efficiency.
The work group mode lets the network without any wired connection and the second connection
is given to the Ethernet.
Limited lifetime physical device warranty helps in proving the pace of mind.
