- * @file strategy_dpo_manager.h
- *
- * This file implements structs and helper functions to manipulate hICN dpo.
- * An hICN DPO is a combination of:
- *   - a hICN DPO ctx (context) that holds the structure containing the
- *     information to choose the next hop,
- *   - a dpo vft that specify how to update the hICN DPO ctx when a next hop is
- *     added, deleted or updated,
- *   - a strategy containing (see strategy.h): (i) the vpp node that processes Interest packets
- *     subjected to such strategy, (ii) the definition of the vft that defines
- *     the hICN strategy functions
- * An hICN DPO is places as the sole next hop in the vpp loadbalancer, and it containes
- * a list of next hops that will be used by the associated strategy when forwarding
- * interest packets.
