Abstract
An apparatus having logic elements to receive an incoming packet associated with a first service function chain; identify a next hop service function for the incoming packet as a non-reactive service function; create a duplicate packet; forward the duplicate packet to the non-reactive service function; and forward the incoming packet to a next reactive service function. An apparatus having logic to receive an incoming packet associated with a first service function chain (SFC), having a first service path identifier (SPI); determine that the incoming packet has a first service index (SI), and that a next-hop SI identifies a non-reactive service function (NRSF); receive a duplicate packet of the incoming packet; rewrite a service header of the duplicate packet to identify a second SFC having a second SPI; and alter the first SI of the incoming packet to identify a next reactive service function in the first SFC.
