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.

The current patch provides a major refactory of the transportlibrary.
A summary of the different components that underwent major modifications is
reported below.
- Transport protocol updates
The hierarchy of classes has been optimized to have common transport services
across different transport protocols. This can allow to customize a transport
protocol with new features.
- A new real-time communication protocol
The RTC protocol has been optimized in terms of algorithms to reduce
consumer-producer synchronization latency.
- A novel socket API
The API has been reworked to be easier to consumer but also to have a more
efficient integration in L4 proxies.
- Several performance improvements
A large number of performance improvements have been included in
particular to make the entire stack zero-copy and optimize cache miss.
- New memory buffer framework
Memory management has been reworked entirely to provide a more efficient infra
with a richer API. Buffers are now allocated in blocks and a single buffer
holds the memory for (1) the shared_ptr control block, (2) the metadata of the
packet (e.g. name, pointer to other buffers if buffer is chained and relevant
offsets), and (3) the packet itself, as it is sent/received over the network.
- A new slab allocator
Dynamic memory allocation is now managed by a novel slab allocator that is
optimised for packet processing and connection management. Memory is organized
in pools of blocks all of the same size which are used during the processing of
outgoing/incoming packets. When a memory block Is allocated is always taken
from a global pool and when it is deallocated is returned to the pool, thus
avoiding the cost of any heap allocation in the data path.
- New transport connectors
Consumer and producer end-points can communication either using an hicn packet
forwarder or with direct connector based on shared memories or sockets.
The usage of transport connectors typically for unit and funcitonal
testing but may have additional usage.
- Support for FEC/ECC for transport services
FEC/ECC via reed solomon is supported by default and made available to
transport services as a modular component. Reed solomon block codes is a
default FEC model that can be replaced in a modular way by many other
codes including RLNC not avaiable in this distribution.
The current FEC framework support variable size padding and efficiently
makes use of the infra memory buffers to avoid additiona copies.
- Secure transport framework for signature computation and verification
Crypto support is nativelty used in hICN for integrity and authenticity.
Novel support that includes RTC has been implemented and made modular
and reusable acrosso different transport protocols.
- TLS - Transport layer security over hicn
Point to point confidentiality is provided by integrating TLS on top of
hICN reliable and non-reliable transport. The integration is common and
makes a different use of the TLS record.
- MLS - Messaging layer security over hicn
MLS integration on top of hICN is made by using the MLSPP implemetation
open sourced by Cisco. We have included instrumentation tools to deploy
performance and functional tests of groups of end-points.
- Android support
The overall code has been heavily tested in Android environments and
has received heavy lifting to better run natively in recent Android OS.
