Lesson 6: Network Communications

Network communications provide the required connectivity for distributed GIS operations. Network capacity, in many cases, can limit the software technology solutions that perform well within your organization. System architecture design must identify and address network communication constraints and provide the right technical solution for a successful GIS implementation.

Exercise 6: Use the CPT to explore network communications
Network traffic contention is the most common cause of distributed GIS performance problems. Traffic contention occurs when network traffic throughput demands exceed available network bandwidth.
