Abstract
In one example, a collection network node comprising a plurality of ingress ports obtains, at a first one of the plurality of ingress ports, a first copy of a packet of a packet flow comprising a plurality of packets. The collection network node determines whether the collection network node had previously obtained a copy of any of the plurality of packets of the packet flow. When it is determined that the collection network node had previously obtained a copy, the collection network node determines whether the collection network node had previously obtained a copy at the first one of the plurality of ingress ports or at a different one of the plurality of ingress ports. When it is determined that the collection network node had previously obtained a copy at a different one of the plurality of ingress ports, the collection network node refrains from forwarding the first copy.
