QUICShift Architecture

QuickShift Architecture - Step by StepAdaptive QUIC-Based File Transfer with Blake3 VerificationStep 1: Data Input Module📄 File Input: test_data.bin (10MB)• Read file from disk using std::fs::File• Load into memory buffer (Vec<u8>)Blake3 ReadyHasher initializedFile data flowsStep 2: Adaptive Task Control Module🎯 Network Quality Analysis and Strategy Calculation• Monitor: Latency (10-100ms), Bandwidth (20-200 Mbps), Packet Loss (0-5%)• Calculate Quality Score: (1/latency) × bandwidth × (1 - loss)• Determine: Chunk Size (16-75KB) | Concurrent Streams (4-18) | Result: 60 adaptationsStrategy appliedStep 3: Tokio Task Creation and Parallel Processing⚡ Rayon Parallel Chunking + Tokio Async Tasks• Split file into chunks (336 chunks total)• Rayon parallel_iter: Compress each chunk + Blake3 hash computation• tokio::spawn: Create async tasks for each chunk (4-18 concurrent)✓ Blake3 HashPer-chunk verification336 hashes computedTasks readyStep 4: QUIC Transport Layer (0-RTT)🌐 Send chunks via concurrent QUIC streams• Protocol: QUIC over UDP (TLS 1.3 encrypted)• Each stream: Send [Blake3 hash (32 bytes)] + [compressed chunk data]• Features: No head-of-line blocking | Connection migration | 291.24 Mbps throughputStream 1Stream 2Stream Nhash+datahash+datahash+dataNetwork transferStep 5: Receiver and Blake3 Verification📥 Receive, verify, and write data• Accept multiple concurrent streams (326 chunks received)• For each chunk: Blake3(received_data) == transmitted_hash → ✓ Verify integrity• Decompress and write to disk | Result: 0 failures, 100% integrity ✓✓ Blake3 VerifiedAll chunks validated0 hash mismatchesBlake3 Verification Chain⚡ Result: 0.29s transfer | 291.24 Mbps | 336 chunks | 0 failures | 12.2x faster than TCP
