2021-04-15[HICN-690] Transport Library Major RefactoryLuca Muscariello1-1/+0
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.
