DATA TRANSMISSION SYSTEM PROVIDING IMPROVED FAILURE RESILIENCE

摘要

The present document relates to a transmission system (100) for transmitting data comprising an Ethernet network portion (110), a transport network portion (120) and a switching component (130) coupling said Ethernet network portion (110) with said transport network portion ( 120); the Ethernet network portion (110) comprising at least two Ethernet line cards (111, 112) each with at least one Ethernet interface (111a, 112a) for providing redundant communication links within the Ethernet network portion (110); the Ethernet line cards (111, 112) being configured to transmit information regarding the status of their at least one Ethernet interface (111a, 112a) to the switching component (130); and the switching component (130) being configured to receive and analyze information regarding the status of the Ethernet interfaces (111a, 112a) of the Ethernet line cards (111, 112) and route the data to the transport network portion (120) based on said received information.
