Network Troubleshooting Through the OSI Model
When it comes to network troubleshooting, working through the Open Systems Interconnection (OSI) model is a straightforward process. With the exception of Layer 1, each layer of the OSI model relies on the next lower layer to provide services as specified. Requests drop down and are completed, as every layer interacts with the next layer, both above and below. When dealing with different layers, understanding how each delivers data and functions impacts how you will troubleshoot.
