Ethernet Auto-Negotiation: Enabling Seamless Link Optimization
Ethernet has evolved significantly from 10 Mbps shared media to today’s multi-hundred gigabit high-speed links. One foundational feature that has enabled this scalability and ease of deployment is Auto-Negotiation (AN).
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.
