Abstract
In one embodiment, a method includes receiving, by an access router, an Internet Protocol version 6 (IPv6) packet that specifies a request for executing a preemptive service for data packets specifying a prescribed flow label field value identified in the request. The method further includes attempting authentication of the request by the access router based on a prescribed secure authentication protocol. The method further includes implementing the preemptive service by the access router based on the authentication of the request, including passing any IPv6 data packet received from a host node and having an IPv6 header specifying the prescribed flow label field value and satisfying a prescribed security condition, and limiting transfer of any data packet that does not specify the prescribed flow label field value or satisfy the prescribed security condition.
