Claim 8:
9. An apparatus, comprising:
one or more interfaces to communicate with a ring of networking devices of a network;
a processor coupled to the one or more interfaces and configured to execute one or more processes; and
a memory configured to store a process that is executable by the processor, the process when executed configured to:
receive traffic from the network;
duplicate the traffic into a duplicate traffic copy;
encapsulate 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
send, 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.
