A method is provided to configure endpoints of a packet routing network, in which one or more endpoints includes Flash storage; multiple endpoints are provided that are configured to impart services to packets; a plurality of information structure portions are provided that associate flow identifiers with next hop destination endpoint addresses to define a plurality of flow identifier-next hop destination endpoint addresses pairs (pairs); different pairs are stored within non-transitory storage devices at different endpoints so that relationships among the next hop destination endpoint addresses of the pairs stored at different endpoints define multiple respective sequences of endpoints that each includes one or more endpoints configured to impart a service and an endpoint that includes Flash storage.
