Chapter 6: Network Layer

1. The Network Layer

   • Encapsulation
   • Addressing end devices
   • Routing
   • De-encapsulation

2. Network Layer Protocols

   • Internet Protocol version 4 (IPv4)
   • Internet Protocol version 6 (IPv6)

3. Encapsulating IP

   • IP encapsulates the transport layer segment or other data by adding an IP header.

4. Characteristics of IP

   • IP was designed as a protocol with low overhead.

5. IP - Connectionless

   • IP is connectionless, meaning that no dedicated end-to-end connection is created before data is sent.

6. IP - Best Effort Delivery

   • Unreliable means that IP does not have the capability to manage and recover from undelivered or corrupt packets.
