Time Sensitive Networking (TSN) Switched End Node core
The TSN Network Core (Switched End Node) from NetTimeLogic is a standalone Time Sensitive Networking (TSN) core according to IEEE…
Overview
The TSN Network Core (Switched End Node) from NetTimeLogic is a standalone Time Sensitive Networking (TSN) core according to IEEE 802.1, IEEE 1588 and IEC 62439-3 standards. It allows to connect to a TSN network, supporting time synchronization, network redundancy, priorities, traffic scheduling, cyclic forwarding, frame preemption, credit-based shaping, etc. It can either run as a Dual Attached Node (DAN) being a redundant endpoint or it can run as a Redundancy Box (RedBox) bridging between a redundant and a non-redundant network. There is also a mode which allows to use the node as a daisy chain node (Switched End Node). The core has three ports: A redundant pair named Ports A&B and an uplink/interlink named Port C. The core is intercepting the path between two Ethernet PHYs and an Ethernet core that forwards or handles Ethernet frames (MAC, PHY or Switch). In addition, it has up to 8 streaming ports which allow to send to and receive frames directly from the specific priority queues and phases.
All tables, protocols and algorithms are implemented completely in HW in the core, no CPU is required, except for configuration. This allows running TSN protocols completely independent and standalone from the user application.

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.
