Safety & Performance
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.
Enhanced Infotainment Clusters
AVB (Audio-Video Bridging) provides guaranteed bandwidth and synchronization for data streams. High-definition video & audio contents now move seamlessly between digital devices with synchronization and no caching delays.
Enhanced Automotive and Safety Systems
TSN (Time Sensitive Networking) adds guaranteed latencies for automotive control functions & the ability to build redundant network paths for safety-critical communications. Excelfore AVB/TSN is AVNU certified, so you also get interoperability with other certified AVB/TSN devices.
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 Protocol Layers of the Network Model
Protocol stacks from Excelfore address layers 2 through 5 of the 7 layer network model: Layer 2—Data Link; Layer 3—Network; Layer 4—Transport; Layer 5—Session. Build these protocols onto the physical layer (Layer 1) and you have a stack ready for APIs (Layer 6) and Applications (Layer 7).

Precise Synchronization
AVB/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): IEEE 802.1AS-2020
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
Managed Network Redundancy
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:
➤ Message timing and synchronization: IEEE 802.1AS / 802.1BA:
Stream Prioritization with Guaranteed Bandwidth
Key TSN protocols shape the network traffic to give priority to mission-critical data:
➤ High-precision grand master clock: IEEE 802.1AS-2020
➤ Stream reservation protocol: IEEE802.1Qcc
➤ Credit-based shaper: IEEE 802.1Qav / 802.1Qat
