Examples include techniques to use a network service header to monitor Quality of Service (QoS). Examples include implementation of a QoS stamping policy to monitor one or more QoS fields of a network packet routed through nodes arranged to separately provide individual service functions included in a service function chain. A determination is made as to whether the QoS stamping information indicates a consistent QoS configuration in the one or more QoS fields of the network packet at node ingress or node egress of the network packet as routed through the nodes.
