The dedicated network is where we would lease a line, basically a direct connection, through a common carrier and connect the three Patties Playhouse building together. We could do this with either a point to point connection, ring architecture connection, star architecture connection, a mesh or partial mesh architecture connection. There are numerous circuits that we could choose to use, depending on our bandwidth requirements. Each connection type has its positives and negatives and there are also cost implications depending on the architecture chosen. An off- shoot of this connection is an ethernet private line which acts like a direct connection but adds significant flexibility in the customers that have variable bandwidth needs. A packet switched circuit is similar to a LAN or BN. Instead of a direct connection like the dedicated network they allow for multiple computers to have multiple connections between each other at the same time. The network establishes either Permanent Virtual Circuits (PVC) or switched virtual circuits depending on what the carrier allows and the customer requirements demand. For a VPN, similar to what you do at your home using an Internet Service Provider (ISP), you must find a carrier and lease a connection that meets your bandwidth requirements. Through the use of a VPN you can create a PVC using the internet and a VPN gateway, a specially designed router (Fitzgerald, Dennis & Durcikova). A.4 Explain your choice for WAN service Reliability is the number one concern for Patties Playhouse. If the client has a bad experience, the game controls are choppy due to delay or unreliable connections then our client base will not continue to visit our establishment and we will soon go out of business due to lack of client traffic. There will be a cost for this reliability. We will go with an ethernet private line which is being used by companies currently in the marketplace. We will rent or lease circuits from common carriers—private companies such as AT&T, Bell Canada, Sprint, and BellSouth that provide communication services to the public and that will allow us to pay for the bandwidth flexibility that we need for our business. (Fitzgerald, Dennis & Durcikova). It acts like a dedicated point to point connection but allows the flexibility to increase/decrease bandwidth requirements based on customer need at a reduced cost when compared to dedicated point to point connections. The ethernet private line does not have the latency issues that you see with packet switch networks and also bypasses the uncertainty of the internet connection when trying to use a VPN. This capability will allow us to expand our bandwidth requirements with just a phone call and be able to support up to 100Gbps, much larger than our current requirement.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
