A method is provided for use with a packet routing network in which one or more endpoints includes Flash storage; multiple endpoints are configured to impart services to packets; a distributed routing structure is provided that includes routing structure portions that are associated with endpoints and that indicate next hop destination endpoint addresses that collectively define multiple sequences of endpoints that each includes one or more endpoints configured to impart a service and an endpoint that includes Flash storage; packets received from an external network are propagated through defined sequences of endpoints; services are imparted to a received packet by endpoints that receive it in the course of its propagation.
