Automotive networks rely heavily on partial networking in which some segments are hibernated and woken up on demand. TC10 will focus on establishing support for sleep mode and a wake-up mechanism tailored for automotive use cases.

Goals:

TC10 specifies the functionality and needs of an Ethernet Sleep and Wake-up concept which includes:

• Support fast wake-up and wake-up request forwarding to support a global wake-up on layer 1

• Support controlled link shutdown to hibernate selected parts of network

• Specify a requirement for global network wake-up time to link-training start

• Comply with standard MAC interfaces

• Comply with Autosar network management

• No unintended wakeup in presence of interference noise

• Applicable to 100BASE-T1, and 1000BASE-T1 (if possible also to future twisted pair PHY specs)
