Ethernet, LAN, WAN & IP Security Training Course and Workshop in Bangalore, Mysore, Chennai, Hyderabad, Pune, Mumbai, Delhi, Noida, Gurgaon, Kolkata

The Ethernet, LAN, WAN technologies & IP Security training course is intended to provide basic knowledge on Ethernet functionality and its application, functionality and application of TCP/IP protocol and IP addressing mechanisms and IP Security concepts. This course will benefit fresh engineers who need to get an introduction to TCP/IP and engineers who work in other areas of telecom and need a background in Ethernet, LAN, WAN technologies.

By attending Ethernet, LAN, WAN technologies & IP Security workshop, delegates will learn to:

Describe how devices communicate across an Ethernet network

Ethernet specifications for physical media:
- 802.3 CSMA/CD Ethernet (ISO/IEC 8802 ISO/IEC 8802-3)
- 802.3i 10BaseT (ISO/IEC 8802-3)
- 802.3u 100BaseT (ISO/IEC 8802-3)
- 802.3z Gigabit Ethernet
- 802.3ab Gigabit Ethernet 1000BaseT 4 pair Cat5 UTP
- 802.3ae 10 Gigabit Ethernet
Explain the Ethernet frame format and the differences between Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet
Explain how the network devices, repeaters, bridges and switches, operated within an Ethernet collision and broadcast domains
Describe Power over Ethernet (PoE) IEEE 802.3af specification to supply data terminal equipment (DTE) power over Ethernet ports and the typical implementation within an Ethernet network
