DATA TRANSMISSION SYSTEM PROVIDING IMPROVED FAILURE RESILIENCE

摘要

A transmission system and method with improved failure resilience is disclosed. The transmission system for transmitting data includes an Ethernet network portion, a transport network portion and a switching component coupling said Ethernet network portion with said transport network portion. The Ethernet network portion includes at least two Ethernet line cards each with at least one Ethernet interface for providing redundant communication links within the Ethernet network portion. The Ethernet line cards are configured to transmit information regarding the status of their at least one Ethernet interface to the switching component and the switching component is configured to receive and analyze information regarding the status of the Ethernet interfaces of the Ethernet line cards and route the data to the transport network portion based on said received information.
