Edge IP Solution

Deterministic Ethernet IP solution with
TSN (Time Sensitive Networking)

Contact our sales team

TTTech Industrial’s Edge IP Solution is a GbE Layer-2 switch IP and software package that supports TSN (Time-Sensitive Networking). Edge IP Solution offers a simple way to connect endpoint devices, such as industrial controllers, over standard Ethernet using TSN. It is suitable for device level networking for industrial applications and integrate directly into your device FPGA to enable 3 to 5 port TSN switching and endpoint functionality.

Evaluate TTTech Industrial’s Edge IP Solution with the DEEvaluation board.

With over 15 years’ experience in time-scheduled networking, TTTech enables Edge IP Solution users to benefit from Guarantee of Service, which allows for the convergence of controls, streaming and data traffic over one standard Ethernet network without affecting real-time performance or wasting bandwidth. In addition, customers can use TSN to configure control networks, seamlessly integrate systems and secure critical network traffic against denial-of-service and network flooding.

TSN Switch Features

IEEE 802.1Qbv
Scheduled Traffic

Provides guaranteed communication latency for time-critical traffic over standard Ethernet even in a converged infrastructure.

IEEE 802.1AS
Time Synchronization

Profile of IEEE 1588v2 for synchronization of clocks in the network. Supports timing requirements for scheduled TSN networks.

IEEE 802.1Qcc
SRP Enhancements

Defines the interfaces for central configuration of TSN networks. Supports configuration models for dynamic scheduling of TSN.

IEEE 802.1Qbu
Frame Preemption

Allows for optimal bandwidth utilization of non-scheduled background traffic sent in parallel with scheduled traffic.
