The invention may be particularly applied to multi-domain networks providing end to end services such as an Ethernet service. Embodiments of the invention use a link protection group for an inter-domain link. Link protection group information relating to the link protection group is used to identify a replacement inter-domain link for a faulty inter-domain link that is configured for an inter-domain service. Once the replacement link is identified, the routing of the inter-domain service may be re-configured from the network element ports of the faulty inter-domain link to the network element ports of the identified second inter-domain link."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fault protection method and fault protection apparatus in a multi-domain network","description":"The present invention relates to a fault protection method and a fault protection device for an inter-domain link of a multi-domain network.
