| 1. A method for routing traffic over a unidirectional link of a computer network configured to implement a routing protocol,
the method comprising the steps of:
dynamically discovering neighboring routers connected to the unidirectional link using the routing protocol in order to establish
an adjacency between the routers over the link, the neighboring routers including a receive-only router connected to a receive-only
side of the unidirectional link and a send-only router connected to a send-only side of the link; and
routing the traffic over the unidirectional link of the network,
wherein the routing protocol comprises the Intermediate System-to-Intermediate System (ISIS) routing protocol.
