Duration: 2 days

Audience: Individuals with any level of involvement performing protocol analysis in TCP/IP network environments.

This course provides a solid foundation for understanding the practical methods for analysing conversations and network statistics in TCP/IP networks using EtherPeek and EtherPeek NX. The focus is on the core IP and TCP functions and discusses analysis techniques for IP Subnet issues, routing, name resolution, dynamic address assignment and reliable movement of data with TCP. Participants will learn the details of TCP sequence number and sliding window analysis.

NAX Certification: WP-103 can help you prepare for the NAX Certificate and is positioned to follow a candidate’s completion of the AATech and PAS Certifications.

T.E.N. Video Workshop:WP-103 is complementary to Session 3, Module 1, "IP Subnetting."
