Detailed Description

Base hICN definitions.

Protocol-independent packet operations.

Macro Definition Documentation

◆ HICN_PATH_LABEL_MASK

#define HICN_PATH_LABEL_MASK 0x000000ff

Path label computations.

Path label is computed by accumulating the identifiers of successive output faces as a Data packet is traveling from its producer back to the consumer originating the Interest.

NOTE: this computation is not (yet) part of the hICN specification.

Enumeration Type Documentation

◆ hicn_payload_type_t

enum hicn_payload_type_t

hICN Payload type

This type distinguishes several types of data packet, which can either carry content data, or Manifest

Function Documentation

◆ hicn_type_is_none()

always_inline int hicn_type_is_none ( hicn_type_t type )

Check if type is none.

Returns: 1 if none, 0 otherwise

◆ update_pathlabel()

always_inline void update_pathlabel	(	hicn_pathlabel_t	current_label,
		hicn_faceid_t	face_id,
		hicn_pathlabel_t *	new_label
	)

Path label update.

Parameters

[in]	current_label	Current pathlabel
[in]	face_id	The face identifier to combine into the path label
[out]	new_label	Computed pathlabel

This function updates the current_label based on the new face_id, and returns
