Abstract
An error recovery method performed in an end node of an Ethernet-based vehicle network includes: detecting, by a physical (PHY) layer processor of a PHY layer of the end node, a physical error of a message, when the message is received at the PHY layer of the end node; detecting, by a controller processor of a controller included in the end node, a logical error of the message; and classifying, by the controller processor, types of the physical error and the logical error.
Claims17
An operation method performed in an end node including a physical (PHY) layer processor in an Ethernet-based vehicle network, the operation method comprising:
- performing, by the PHY layer processor, a monitoring operation of a signal on a port of the end node;
- detecting, by the PHY layer processor, a physical error in the port based on results of the monitoring operation;
- transmitting, by the PHY layer processor, information of the physical error to a controller processor included in the end node;
- determining, by the controller processor, a type of the physical error based on whether a physical channel parameter of the signal matches with at least one of a predetermined physical channel parameter, a receive failure of the signal, a transmit failure of the signal, or a link failure;
- and
- classifying, by the controller processor, the physical error with a critical error or a non-critical error based on the type of the physical error.
An operation method performed in an end node including a controller processor in an Ethernet-based vehicle network, the operation method comprising:
- obtaining, by the controller processor, a message from a physical (PHY) layer processor included in the end node;
- detecting, by the controller processor, a logical error of the message based on a reference parameter;
- determining, by the controller processor, a type of the logical error based on at least whether a format of the message matches a predetermined message format or whether the logical error is due to an error packet;
- and
- increasing, by the controller processor, an error counter value per the type of the logical error.
An operation method performed in a switch including a processor in an Ethernet-based vehicle network, the operation method comprising:
- performing, by the processor, a monitoring operation of a signal on all ports of the switch;
- detecting, by the processor, a physical error based on results of the monitoring operation;
- determining, by the processor, a type of the physical error based on information of the physical error based on whether a physical channel parameter of the signal matches with at least one of a predetermined physical channel parameter, a receive failure of the signal, a transmit failure of the signal, or a link failure;
- and
- classifying, by the processor, the physical error with a critical error or a non-critical error based on the type of the physical error.
