The demand for higher bandwidth in the car is growing quickly.
Overview
The demand for higher bandwidth in the car is growing quickly. On one side, all the entertainment and connectivity elements, and on the other, all the control related electronics.
As a result, the automotive manufacturers are adding a plethora of computer-based systems that need interconnection. Ethernet, with the latest innovations, is the best candidate to face this challenge from the technical and economical point of view.
Historically, the use of packet-switched networks has been avoided by automotive manufacturers for multimedia applications due to their non-deterministic nature. However, deterministic Ethernet solutions, like AVB, deliver streams with guaranteed bandwidth and deterministic latency for highly reliable and low-latency applications like those found within an automobile.
Audio Video Bridging (AVB) is a common name for the set of technical standards that allow time-synchronized low latency streaming services through Ethernet networks. They have been developed by the Institute of Electrical and Electronics Engineers (IEEE) Audio Video Bridging Task Group. These consist of:
•IEEE 802.1BA: Audio Video Bridging (AVB) Systems
•IEEE 802.1AS: Timing and Synchronization for Time-Sensitive Applications (gPTP)
•IEEE 802.1Qat: Stream Reservation Protocol (SRP)
•IEEE 802.1Qav: Forwarding and Queuing for Time-Sensitive Streams (FQTSS)
AVB works by reserving a fraction of the available Ethernet bandwidth for AVB traffic and those type of packets are sent regularly in the allocated slots. As the bandwidth is reserved, there will be no collisions.
AVB/Automotive Ethernet Switch (AVBES) IP Core implements an Ethernet switch which supports all AVB conforming standards. It can be implemented optimally depending on the application, from a simple 2-ports end-point to a complex multiport switch.

Enhancing Ethernet Security with MACsec
Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.
What Makes Ethernet IP Truly Automotive-Grade
This blog examines what separates truly automotive-grade Ethernet IP from generic implementations across functional safety, time-sensitive networking, security, observability, lifecycle management, and the integration disciplines that only become visible once a program is deep into development.
