… to produce entropy with IPv6. However, in the case of IPv6, the "flow label" [ RFC6437 ] may also alternatively be used to provide entropy for load balancing [ RFC6438 ]. This use of the flow label for load balancing is consistent with the definition of the field, although furth…

… and set the flow label value in the IPv6 packet as discussed in Section 3 of [ RFC6437 ] . If the TURN server is incapable of generating the flow label value from the IPv6 packet's 5-tuple, it sets the Flow label to zero. ¶ Alternate behavior: The alternate behavior is the same …

…ts that send data using IPv6 SHOULD apply an IPv6 flow label in compliance with RFC6437 , unless the local API does not allow setting IPv6 flow labels. The flow label generation MUST be designed to minimize the chances of linkability with a previously used flow label, as a stable…
