The Evolved Packet System (EPS) is one of the most transformative technologies developed within my lifetime. It was in response to, but also enabled, the rise of internet-first mobile devices. Today, it forms the basis of the next generation of innovations like self-driving cars. This presentation provides a brief overview of the EPS, as well as how EPS shows us how to design solid protocols.
Key Take Aways
- Protocols are difficult to design, but it is critical that people take time to develop them peroperly
- Standardization between products is good for customer experience, especially with roaming
- When possible, user needs and future adoption should be central to protocol development
- Protocols should be invisible to the user

- At 5:31, I make a comment that vehicles in China connect to Cisco networks. I have not verified that any Chinese manufacturers connect to the Cisco Packet Core. I regret this error immensely.
- At 27:54, the slide says 2022 but I say 2021. 2022 is the correct date.
