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)
