Abstract
According to various embodiments, a networking device in a network receives traffic from the network. The networking device duplicates the traffic into a duplicate traffic copy. The networking device encapsulates the duplicate traffic copy into a multicast frame. The networking device sends, via a multicast address, the multicast frame to a network sensor in the network for analysis, wherein the multicast address is reserved in the network for traffic analysis.
