Dual homing is a mechanism by which an access network employs pair of switches in the transport network as if it were connecting to a single device. Conventional arrangements for defining multiple paths from a transport network to an access network suffer from the shortcomings of potential routing loops, increased hops to the access network, and inability or inconsistency with forwarding to different types of access networks, and may involve redirecting traffic absent faults in the access network. The dual homed network switches identify the type of access network and perform switching logic corresponding to the access network type to provide comprehensive dual-homed support to the access network independently of the type of transport employed in the access network, and employ redirection only if there is a fault in the access network."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Access network dual path connectivity","description":"A transport network employs dual homing to an access network to provide connectivity from multiple network switches.
