ABSTRACT:
A network system includes end nodes which are connected to a plurality of cascaded hubs. Each hub is able to generate a network error packet when a timeout is detected. More specifically, a first hub starts a first timer upon the first hub acknowledging a grant to a first device connected to a first port of the first hub. Upon expiration of the first timer without the first hub beginning to receive a first network packet over the first port, the first hub begins to send a first error packet to a second device connected to the first hub. If the first hub begins to receive a second error packet over the first port after expiration of the first timer and before the first hub has completed sending the first error packet, the first hub appends the second error packet to the first error packet. If the first hub does not begin to receive any error packet over the first port before completely sending the first error packet, the first hub marks the first port as failed.
