3-2 Milestone One
I have been given the task of coming up with a development plan to expand our network to include the newly proposed Fayetteville, NC office. The new office will require its own VPN (Virtual Private Network) to connect to the company's personal WAN network (Wide Area Network). The company will expect there to be employees who will work from home and employees who take their work home with them. Those employees will require a secure remote connection to the company’s personal network.
The Open Systems Interconnection or (OSI) for short is a theoretical model that is used to
define how a company’s data will be transmitted and received across networks and that the use of this model will offer a couple of benefits including providing common language protocols and
the ability to divide network tasks into a logical order which can offer help when needing to perform troubleshooting. The OSI model comes in seven layers that data must travel through the portal and during the sending process it must be able to do so in reverse order as well. The seven layers of OSI are as follows below.
1.
Physical Layer
– The physical layer sets the standards of how the computer reads data as electrical signals and pulses of lights and this layer is also specific with cable and connector specs as well as the physical topology of the network.
2.
Data Link Layer – This layer is comprised of physical network devices that receive unique hardware addresses. The data link layer also distinguishes levels of
access and is responsible for providing verification that data has arrived and without any errors.

3.
Network Layer – This layer is the one where routers operate by identifying hosts and networks to determine which is the closest to data hop for a data transfer to happen efficiently.
4.
Transport Layer – The transport layer serves as a transition between the upper and the lower layers of OSI and it provides a data flow control.
5.
Session Layer – This layer’s main responsibility is to keep track of the session connection and keep the data streams separated by the assignment of unique session IDs.
6.
Presentation Layer – In this layer, the data is formatted and translated into a compatible form to receive and not to mention encryption and compression also occur at this level.
7.
Application Layer – The application layer enables communication between the client and the service and this layer is also the human-computer interaction layer.
The topology of the network is a very important thing to be considered as there are a few different options to choose from that each have their own drawbacks and benefits. The cheapest and most simple option would be a bus topology which consists of each node being connected to a singular cable. This option will not fit the needs of the company, The next option would be a ring topology which is where each of the nodes is connected to the one next to it in the loop. The ring topology has a feature that normally reduces data collisions but this option is not fully adequate for the needs of the company because a large portion of the Fayetteville employees will
be remote workers and are not physically connected to the company network. The next recommendation is the star topology and, in this version, each node is connected to a central connecting point which allows this topology version to be easily scalable and will provide

Discuss the concept of WANS as it relates to cloud computing. Traditionally, networks were seen has hub and spoke
topologies where WANS connected privately owned LANS together. Today, there are often connectivity with cloud
providers and also related third parties. How can you ensure that these connections are secure? How else might this
change the way you think about your network? Review your classmates' posts and respond to at least one of them.

A network may require an upgrade to one of the faster Ethernet topologies. Most Ethernet networks support speeds of 10 Mbps,100 Mbps and 1000 Mbps. The new generation of multimedia, imaging, and database products can easily overwhelm a network that operates at traditional Ethernet speeds of 10 and 100 Mbps. Network administrators may choose to provide Gigabit Ethernet and 10Gigabit Ethernet from the backbone to the end user. Using relevant diagrams, illustrate how Ethernet technologies can be used economically in a campus network.
