Ethernet for Automotive
Ethernet Architecture for Future Vehicles
Open Alliance TC 8: Testing of ECU´s
Automotive Ethernet includes the following ISO/OSI layers:
Layer 1: Physical Layer OPEN Alliance BroadR-Reach (OABR)
Layer 2: Data Link Layer, e.g. IEEE Ethernet MAC + VLAN (802.1Q), ARP
TCP/IP Protocol Family includes following ISO/OSI layers:
Layer 3: Network Layer, e.g. IP, ICMP
Layer 4: Transport Layer, e.g. UDP, TCP, DHCP
Automotive Protocols includes the following ISO/OSI layers:
Layers 5-6-7: Application -oriented layers, e.g. UDP-NM, SOME/IP, SD
TC 8: Testing of ECU´s
OPEN Alliance TC8 Ethernet Test Scope
OPEN Alliance (TC8) Scopes for ECUs
• Conformance Tests
• Performance Tests
• Stress Tests (against Conditions)
• Interoperability Tests
• Switch Tests
• Application Specific Tests

Strong Partnership between IXIA and IHR
Test Capabilities of the Ixia equipment:
•Test TCP/IP stack conformance as per latest OPEN & AUTOSAR specifications, as Ixia was•main contributor for OPEN Alliance ECU test (~90% of test cases came from IxANVL)•document owner for AUTOSAR Acceptance Test (close to 100% coverage of AUTOSAR)
•Test automotive switches – performance, robustness with RFC 2544 and RFC 2889•also supported are flexible VLAN configuration tests as per TC8 specification
•Test automotive AVB switch/endpoint as per latest AVnu Automotive profile specification 1.4
