#2 – Transmit / Analyze Packets
1. Automotive embedded
A requirement to transmit and analyze Ethernet packets in
the embedded application.
One focus of embedded Ethernet systems is the transmission of
periodic signals in contrast to office network oriented IP tools.
An IP tool that provides comprehensive functionality for the
analysis of periodic signals.
An IP tool that can create and transmit a firm’s proprietary
protocol, as well as, receive and read out individual Ethernet
packets.

#3 – Gateway
1. Automotive embedded
2. Transmit / analyze packets
A need for gateways between Ethernet and other bus
systems.
An IP tool that provides the possibility to analyze the
communication of gateways between Ethernet and other bus
systems like CAN, FlexRay, MOST, WLAN etc.
An IP tool that can measure the delay time of the transition
between Ethernet and other bus systems.

#4 – Isolation
1. Automotive embedded
2. Transmit / analyze packets
3. Gateway
A requirement for an IP tool that protects against spurious
packet transmissions.
Most real-time systems are not tolerant when false packet are
transmitted.
An IP tool that isolates the computer’s operating system and
other applications from transmitting Ethernet packets onto the
automotive embedded network.
