Traffic received at a node of the transport network is mapped to Layer 1 data transport units according to destination such that each Layer 1 data transport unit carries traffic for a particular destination of the transport network. The Layer 1 transport network can carry a plurality of different traffic types and the node can map the received traffic to Layer 1 data transport units according to destination and traffic type. Identification information can be added to an overhead section associated with the Layer 1 data transport unit to indicate at least one of: traffic type and destination of the traffic carried within the data transport unit. At a subsequent node, the Layer 1 data transport units are received and switched such that Layer 1 data transport units carrying traffic destined for other nodes bypass higher layer processing at the node and Layer 1 data transport units carrying traffic destined for the node are switched to a local output of the node."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Traffic differentiation in a transport network","description":"A Layer 1 transport network, such as an Optical Transport Network (OTN), transports traffic in Layer 1 data transport units.
