Abstract
A network architecture for use in a data traffic network that includes a plurality of nodes and a plurality of data links coupling the nodes. The network architecture includes a working data link( ) that forms a signal pathway between a first router ( ) and a second router ( ) within the network. A protection data link( ) is likewise provided and forms a second signal pathway. The routers ( ) include both working data ports ( ) and protection data ports ( ) with each port including associated transmit and receive terminals. A combination of line splitting devices ( ), line selection devices ( ) and switch arrays ( ) are used to switch the flow of traffic data from the working data link ( ) to the protection data link ( ) or a protection channel ( ) as is appropriate.
