Internet Plumbing

Internet Plumbing is a word-game with multiple layers of meaning (ha! a recursive pun ;-)

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!

Protocol stack hourglass 1.jpeg
  • 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-layers-ti-shirt-download.jpeg 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!!) 

Description of OSI layers

Borrowed from: https://en.wikipedia.org/wiki/OSI_model

The recommendation X.200 describes seven layers, labeled 1 to 7. Layer 1 is the lowest layer in this model

OSI Model
Layer Protocol data unit (PDU) Function<ref>Template:Cite web</ref> Examples
Host
layers
7. Application Data High-level APIs, including resource sharing, remote file access, directory services and virtual terminals TLS, FTP, HTTP, HTTPS, SMTP, SSH, Telnet
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
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
Media
layers
3. Network Packet Structuring and managing a multi-node network, including addressing, routing and traffic control AppleTalk, ICMP, IPsec, IPv4, IPv6
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
