SNHUEnergy Inc. is an expanding company with a high number of employees; the number is prospected to develop by 50% in the next 18 months; for the company to continue running efficiently, the network has to go under a high-level overview to be able to sustain the ever growing network activities in the company; the requirements met with the current networking architecture cannot support the growing networking rate of the company, a future model has to be adopted and requirements delivered (Janssen & Lankhorst, 2017); the current architecture uses only one firewall located in Dallas Office; the presence of other offices in Memphis, renders the architecture to security threats on connections and communications. SNHUEnergy is projected to have a total number of 240 employees in the next two years; the single router in Memphis and Dallas with a total of 3 switches and no firewalls in Memphis with limited applications in the current networking architecture will highly affect the effectiveness of communication if the current system is used through; the new Architecture recommendation will also cater for the offices in Kansas City and Houston.
A recommendation will be that; the core of the network must be hosted in multiple 4+ fault-tolerant data centers; this will be geographically diverse and operated by a common provider in Dallas, Texas, through wireless communication for the outlets and wired communication for the offices in the headquarters. Traffic measurements in the SNHUEnergy Inc. will also be essential for the traffic engineers to accurately measure and analyze the network behavior characteristics, enabling them to predict real traffic characteristics to determine the quality of the network and the performance scope; in SNHUEnergy Inc., the analysis of the traffic pattern will be inclusive of how the internet plays a role in the network architecture’s web services.
The Open Systems Interconnection (OSI) model defines a networking framework to implement protocols in layers with control passed from one layer to the other layer; it is a teaching tool today. The seven layers include:
Physical Layer- this layer is responsible for the ultimate transmission of digital data bits from the physical layer of sending the device over network communications media to the physical layer of the receiving device.
Data Link Layer- this layer checks for physical transmission errors when retrieving data from the physical layer; it checks for physical transmission errors and packages bits into data “frames”; it also addresses physical addressing schemes.
Network Layer- this layer adds the concept of routing above the data link layer such that when data arrives at the network layer the destination details are examined if they have arrived at the right destination.
Transport Layer- This layer delivers data across network connections an example is TPC.
Session Layer- This layer manages the sequence and flow events that initiate and tear down network connections.
Presentation Layer- This function as handler of syntax processing of message data such as format conversations and encryption and decryption;
Application Layer- Supplies network services to end user applications.
The diagram below shows how the internet will enable the company monitor the traffic measurements in the various departments and the expansion to transportation and refinement.
