Abstract
In a data communication internetwork including a source station, an end station, and a default router for the source station, a default communication path including the default router is defined between the source station and the destination station. During operation of the data communication internetwork, a shortcut data communication path by passing the default router is established between the source station and the destination station, such that data packets transmitted by the source station are not received by the default router. After the shortcut communication path has been established, a control frame containing source-route information regarding the source station is transmitted to the router, and the source-route information is stored at the router. In this manner, the default router can efficiently direct data packets to the source station and facilitate the establishment of shortcut communication paths terminating at the source station even though the default router is bypassed by a shortcut communication path.
