For selecting an active pseudowire (PW13) to be used for forwarding user traffic, the provider edge node (201) determines a local preferential forwarding status for each of the pseudowires (PW13, PW14). The determined preferential forwarding status is active for no more than one of the pseudowires (PW13, PW14). The provider edge node (201) indicates the determined local preferential forwarding status of the pseudowires (PW13, PW14) to remote provider edge nodes (203, 204). Further, the provider edge node (201) receives indications of a remote preferential forwarding status for each of the pseudowires (PW13, PW14) from the remote provider edge nodes (203, 204). The provider edge node (201) then selects that one of the pseudowires (PW13, PW14) as active for which both the local preferential forwarding status and the remote preferential forwarding status is active."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Pseudowire selection in a pseudowire redundancy network","description":"A pseudowire redundancy network comprises a plurality of pseudowires (PW13, PW 14) attached to a provider edge node (201).
