Packet Analysis Power Workshop (PAPW)

Network administrators, network managers and all technical staff who are responsible for planning, implementing, and ensuring high performance operation of their data networks.

Fondamenti di Networking e TCP/IP (NWFITA)

Participants will receive a comprehensive introduction into the features, functions and the usage of the Wireshark Analyzer and will learn methods and techniques about monitoring and analysis of their networks from the packet level. This course will also focus on the detailed analysis and troubleshooting of typical network protocols and applications with specific focus on switched Ethernet, TCP/IP networks and TCP/IP based applications.
