Analyzing the OSI Model

Week 5 Discussion

Analyzing the OSI Model
The Open Systems Interconnection model (OSI) provides a way of conceptualizing a communication system. It does this by partitioning the system into layers. The OSI model is a standard developed by the International Organization for Standardization (ISO). It is an excellent example of abstraction and layering applied to a complex system. Gaining a thorough understanding of the OSI model can help you design, develop, and troubleshoot distributed applications.
For this Discussion, you will evaluate the failure of a distributed application and analyze where in the OSI Model the failure may be related to.
To prepare:
    Consider a distributed application that you use and for which you have experienced a recent failure.
By Day 3, post a 2- to 3-paragraph evaluation of the application failure you dealt with. Do the following:
    Describe the application and the failure.
    Analyze the failure relative to each layer of the OSI model. For each layer, identify and describe at least one service from that layer that may have failed and caused the application failure you experienced.
    Explain which layer you consider to be the most likely cause of the failure you experienced and why.
