this task cover a large part of the codebase and involves several changes:
- the library provides a name data structure (hicn_name_t ), which is composed
of a name prefix (hicn_name_prefix_t) and a name suffix (hicn_name_suffix_t),
and it has been extended to provide all support functions required for name
manipulation, including common prefix computation, as required for the Longest
Prefix Match (LPM)in the forwarder, in addition to Exact Prefix Match (EPM).
- all code has been rewritten to use this data structure instead of having for
instance the forwarder define its own name class (used to be Name and NameBitVector)
the code has been refactored to minimize name allocations and copies, one remaining
aspect is the difference of name storage between PIT and CS entries (respectively
in the PIT entry, and in the message buffer), which causes the packet cache
index to be updated when a PIT entry is converted into a CS entry. By storing
the name in the PIT/CS entry everytime, we might save on this operation).
- hicn-light FIB has been rewritten : code has been refactored and should now be
shorter and documented; unit tests have been drafted but more would be required
to cover all cases and match the algorithms to add/remove nodes, as specified in the doc.
all protocol details and hICN header formats are now abstracted by the library
for the forwarder (and thus header.h and protocols/*.h have been removed from
public includes, and replaced by packet.h providing protocol agnostic packet
level functions, completely replacing the compat.h header that used to provide
similar functions.
- this works by exposing a opaque buffer to the application (a kind of socket buffer)
which is used by the lib to cache the packet format and offsets of the different
layers in the buffer and provider efficient operations (the packet format is
either defined for packet construction, or guessed at ingress, and this structure
is updated accordingly only once).

The current patch provides several new features, improvements,
bug fixes and also complete rewrite of entire components.
- lib
The hicn packet parser has been improved with a new packet
format fully based on UDP. The TCP header is still temporarily
supported but the UDP header will replace completely the new hicn
packet format. Improvements have been made to make sure every
packet parsing operation is made via this library. The current
new header can be used as header between the payload and the
UDP header or as trailer in the UDP surplus area to be tested
when UDP options will start to be used.
- hicn-light
The portable packet forwarder has been completely rewritten from
scratch with the twofold objective to improve performance and
code size but also to drop dependencies such as libparc which is
now removed by the current implementation.
- hicn control
the control library is the agent that is used to program the
packet forwarders via their binary API. This component has
benefited from significant improvements in terms of interaction
model which is now event driven and more robust to failures.
- VPP plugin has been updated to support VPP 22.02
- transport
Major improvement have been made to the RTC protocol, to the
support of IO modules and to the security sub system. Signed
manifests are the default data authenticity and integrity framework.
Confidentiality can be enabled by sharing the encryption key to the
prod/cons layer. The library has been tested with group key based
applications such as broadcast/multicast and real-time on-line
meetings with trusted server keys or MLS.
- testing
Unit testing has been introduced using GoogleTest. One third of
the code base is covered by unit testing with priority on
critical features. Functional testing has also been introduce
using Docker, linux bridging and Robot Framework to define
test with Less Code techniques to facilitate the extension
of the coverage.
