摘要： In general, techniques are described for extending network connectivity software utilities, such as traceroute, to provide complete visibility into a network topology between a source device and a destination device, even when an intermediate network device may be actively utilizing multiple network links when forwarding packets toward the destination. In one example, a network device coupled to a plurality of paths and positioned between a source network device and destination network device may receive a traceroute packet. The network device may also, for each of the plurality of paths, modify a payload of the traceroute packet to include a respective identifier for a corresponding path of the plurality of paths to construct a respective modified traceroute packet for the corresponding path. The network device may also forward the respective modified traceroute packets on the corresponding paths.

摘要： In some embodiments, an apparatus includes a layer-2 device operably coupled to a source device and a destination device and disposed within a data path (1) between the source device and the destination device, and (2) includes at least one layer-3 device. The layer-2 device receives a first test data unit from the source device, and defines a quality datum associated with processing the first test data unit. The layer-2 device defines a second test data unit based on the first test data unit that includes the quality datum associated with processing the first test data unit. The layer-2 device sends the second test data unit to the layer-3 device. The layer-3 device defines a quality datum associated with processing the second test data unit at the layer-3 device and defines a third test data unit based on the second test data unit.
