Concept

- Networking (edge - core)- Internet- Protocol- Switch network vs Broadcast network- Package switching vs Virtual circuit

switching

OSI - TCP/IP

TCP/IP

Why?

TCP/IP

- Reliable? Where? Why?

Application layer - HTTP

- Stateless. Why?- HTTP (v1.0 vs v1.1)- Web proxy- 401- Cache

Application layer

- FTP- SMTP- POP3/IMAP- DNS

Transport layer - UDP

- services and principles- checksum- rdt 2.0 2.1 2.2 3.0

Transport layer - TCP

- 3-ways handshake- point to point- reliable- full-duplex- flow control- sliding window

Internet layer - Route

- Global (Link state - Dijkstra)- Decentralized (distance vector)

- Static- Dynamic

Internet layer - IP

- IPv4- IPv6

Network Interface layer

- Repeater, hub- Bridge, switch

- TDMA- CDMA- CSMA (Carrier sense)

Network Interface layer

- MAC- ARP

- Ethernet- Fiber
