Key ideas in How Computer Networks Gossip
- The internet breaks every piece of digital media into tiny, discrete units called packets
- Sending massive files in one unbroken piece would block networks whenever a transmission stalled or faced errors
- Every network packet requires a destination IP address so network equipment knows where to route it
- Every packet requires a sender IP address so the receiving device knows where to send replies or report lost data
- Network routers independently steer packets based on current congestion and open links
- Packets belonging to the exact same file often take wildly different geographical routes across continents and oceans
- Because packets take different paths, they frequently arrive at the receiving device out of order
- Each packet carries a sequence number indicating its exact position in the original data
- The receiver uses these sequence numbers to piece the scattered data back into the original file
- Computers route traffic using numerical IP addresses, not human words
- DNS acts like a digital phonebook, looking up a domain name and translating it into an IP address
- Routers look at the destination IP header on incoming packets like an envelope address
- Routers pick the best available outgoing path at that microsecond to avoid congested lines
- A router does not need to open or alter the actual data payload to steer it
- Routers constantly exchange status updates about which paths are alive or broken
- When a physical line breaks, routers automatically re-route data across alternative surviving links without cutting off users
