IMPLEMENTING A SWITCH FABRIC RESPONSIVE TO AN UNAVAILABLE PATH

摘要

In a method for implementing a switch fabric, in a first fabric chip, a packet comprising an identification of a destination node chip is received from a source fabric chip, and a determination that a first path in the switch fabric along which the packet is to be communicated toward the destination node chip is unavailable is made. In addition, a determination as to whether another path along which the packet is to be communicated toward the destination node chip that does not include the source fabric chip is available is made. In response to a determination that the another path is available, the packet is communicated along the another path. In addition, in response to a determination that the another path is unavailable, the packet is communicated back to the source fabric chip.
