Description

Time-sensitive networks in critical systems often use frame replication to improve network reliability.

RELIABLE is a new patented algorithm to perform frame elimination more efficiently when using frame replication. The solution remains 100% compatible with the FRER standard defined by IEEE 802.1 CB.

The new approach brings performance improvements in terms of latency, memory usage and robustness.

The implementation is designed to be hardware-accelerated in an ASIC or a FPGA, typically as part of a network device.
