Abstract
The present disclosure relates to a technique of redirecting Ethernet based tunnelled Internet Protocol (“IP”) traffic in an IP communications network, wherein the Ethernet based tunnelled IP traffic is transmitted from a first network node 10 to a second network node 20 of the IP communications network. A method embodiment comprises the steps of: receiving 202, by a device 30 for redirecting the Ethernet based tunnelled IP traffic, an Ethernet based tunnelled IP packet transmitted from the first network node 10, the Ethernet based tunnelled IP packet including a header and a payload, the header containing a destination Ethernet address and the payload containing an inner user IP header of an inner user IP packet; modifying 204, by the device 30, the destination Ethernet address contained in the header of the Ethernet based tunnelled IP packet on the basis of the inner user IP header; and selecting 206, by the device 30, a Processing Unit (“PU”) 50b for traffic analysis from a plurality of PUs 50a, 50b, . . . , 5Oz for redirecting the Ethernet based tunnelled IP packet to the selected PU 50b in accordance with the modified destination Ethernet address.
