Internet Plumbing
Internet Plumbing is a word-game with multiple layers of meaning (ha! a recursive pun ;-)
Series of Tubes
- https://en.wikipedia.org/wiki/Series_of_tubes

Ubiquitous and complicated as plumbing?
- Internet as a utility
- just like "plumbing" (water & sewage), there is underlying "technology" to it, so complex, that no-one seems to grasp how all of it works
- 60% of the population of the planet does NOT have "teh Internets", and 30% does not have plumbing either (http://www.un.org/waterforlifedecade/sanitation.shtml)
Acronyms!
- TCP/IP
- IPv4, IPv6: Internet Protocol (IP) addresses
- NAT: Network Address Translation
- DNS: Domain Name System
- ASN: Autonomous System Number
- used for BGP routing (Border Gateway Protocol)
- IXP: Internet eXchange Point
- SMTP
- HTTP
- CDN

Overview
OSI Model T-shirt enhanced to include an 8th and 9th layer as defined by Evi Nemeth: https://en.wikipedia.org/wiki/Evi_Nemeth // https://www.isc.org/product/isc-9-layer-osi-model-cotton-t-shirt/
(TODO: add ISC reference to Evi's wikipedia page!!)
Comparing OSI & TCP / IP layers
Original borrowed from: https://en.wikipedia.org/wiki/OSI_model
| TCP / IP Model | OSI Model | |||
|---|---|---|---|---|
| Layer | OSI Layer | Protocol data unit (PDU) | Function | Examples |
| Application | 7. Application | Data | High-level APIs, including resource sharing, remote file access, directory services and virtual terminals | TLS, FTP, HTTP, HTTPS, SMTP, SSH, Telnet, BGP! |
| 6. Presentation | Translation of data between a networking service and an application; including character encoding, data compression and encryption/decryption | CSS, GIF, HTML, XML, JSON | ||
| Transport | 5. Session | Managing communication sessions, i.e. continuous exchange of information in the form of multiple back-and-forth transmissions between two nodes | RPC, SCP, NFS, PAP, | |
| 4. Transport | Segment (TCP) / Datagram (UDP) | Reliable transmission of data segments between points on a network, including segmentation, acknowledgement and multiplexing | NBF, TCP, UDP | |
| Network / Internet |
3. Network | Packet | Structuring and managing a multi-node network, including addressing, routing and traffic control | AppleTalk, ICMP, IPsec, IPv4, IPv6 |
| Link layer |
2. Data link | Frame | Reliable transmission of data frames between two nodes connected by a physical layer | IEEE 802.2, L2TP, LLDP, MAC, PPP, ATM, MPLS |
| 1. Physical | Bit | Transmission and reception of raw bit streams over a physical medium | DOCSIS, DSL, Ethernet physical layer, ISDN, USB | |
Cross-layer functions:
- ARP is used to translate IPv4 addresses (OSI layer 3) into Ethernet MAC addresses (OSI layer 2).
- Domain Name Service is an Application Layer service which is used to look up the IP address of a given domain name. Once a reply is received from the DNS server, it is then possible to form a Layer 3 connection to the third-party host.
- etc
