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
