APFTP v2: Adaptive Parallel File Transfer Protocol for High-Performance and Reliable Data Transfer

APFTP (Adaptive Parallel File Transfer Protocol) is a next-generation application-layer file transfer protocol designed to improve throughput, reliability, and adaptability over conventional transfer mechanisms. This work introduces adaptive parallel stream management, intelligent chunk scheduling, congestion-aware transmission, dynamic retry mechanisms, and comprehensive performance evaluation through localhost experimentation. The paper presents the protocol architecture, packet structure, algorithms, implementation details, experimental methodology, benchmark results, limitations, and future research directions. Contents include:• Complete protocol specification• System architecture• Adaptive scheduling algorithm• Experimental validation• Performance comparison• Security considerations• Implementation details• Future work This repository contains the research paper and supplementary material associated with APFTP v2.
