Claim 15:
16. A tangible, non-transitory, computer-readable medium storing program instructions that cause a networking device in a network to execute a process comprising:
receiving, at the networking device in the network, traffic from the network;
duplicating, by the networking device, the traffic into a duplicate traffic copy;
encapsulating, by the networking device, the duplicate traffic copy into a multicast frame wherein the multicast frame is assigned a different Quality of Service (QoS) policy as that of the traffic; and
sending, by the networking device and via a multicast address, the multicast frame to a network sensor in the network via one or more intermediate devices between the networking device and the network sensor for analysis, wherein the multicast address is reserved in the network for traffic analysis, such that the one or more intermediate devices forward the multicast frame to the network sensor using their uplink port only.
