Scalable Network Bandwidth and Dynamic Switching

Ethernet enables cost-effective in-vehicle bandwidth scaling from 10MB multi-drop to 10GB and beyond. It also brings dynamic network switching, network  security and the ability to reach devices from the Cloud.

Flexible-Subscription-Models
IP Addressing and Accessibility for CAN Buses

SOME/IP, DoIP, RTP, RTCP and UDS protocols from Excelfore bring your legacy systems forward into the age of the Software Defined Vehicle, integrating seamlessly into an Ethernet backbone to provide full cloud accessibility to your CAN based devices.

Key Features

Sharpen Your Competitive Edge

Adaptive Compression
Precise Synchronization, Redundant Grandmaster & IEEE1588 Support

TSN networks provide a grand master clock to enable network traffic and connected devices to precisely synchronize across the network
➤ Generalized precision time protocol (gPTP) and redundant grandmaster: IEEE 802.1AS-2020
➤ Multi Clock Domain Support: IEEE1588

Guaranteed Latency
Guaranteed Latency

Properly constructed TSN networks guarantee the latency from source to destination across the network, ensuring precision control, decision algorithms and actuations meet specified timing requirements.

Bandwidth Reservation
Managed Network Redundancy & Advanced Traffic Shaping

Key TSN protocols build redundancy into networks in safety-critical domains:
➤ Redundant data paths:  IEEE 802.1Qcb
➤ Redundant grand master clocks:  IEEE 802.1A 2020 / 802.1ASrev
➤ High-precision grand master clock: IEEE 802.1AS-2020
➤ Stream reservation protocol: IEEE802.1Qcc
➤ Time aware shaper:  IEEE 802.1Qbv
➤ Asynchronous traffic shaping: IEEE 802.1Qrc
➤ Traffic pre-emption:  IEEE 802.1Qbu
