TCP b : Additive Increase Multiplicative Decrease & 'Slow Start' - Computerphile

TCP remains the backbone of internet communication by balancing reliability with congestion control, despite being designed in the 1980s. While classroom models suggest a clean 'sawtooth' pattern of packet flow, real-world data reveals a much messier, complex reality where protocols must adapt to unpredictable network conditions without the ability to significantly change their rigid header structures.
Key insight: The 'slow start' mechanism, despite its name, is actually an aggressive exponential growth phase designed to quickly ramp up data transmission speeds before settling into the more cautious Additive Increase, Multiplicative Decrease (AIMD) cycle.

The Transmission Control Protocol (TCP) functions as a stateful abstraction layer that transforms an unreliable, packet-dropping network into a dependable byte-stream. By utilizing a three-way handshake, sequence numbering, and acknowledgement mechanisms, TCP ensures data integrity and ordering, while managing inherent security vulnerabilities like SYN flood denial-of-service attacks.
Key insight: TCP sequence numbers do not start at one for security reasons; they begin with a random number to prevent attackers from predicting and hijacking connections.
