## Cisco Network Traffic Generation & QoS Testing Scripts Write Python scripts that generate controlled network traffic for testing QoS policies and network performance. Follow these standards: ### Traffic Types #### TCP Traffic - Bulk data transfers (saturate a link to test bandwidth shaping) - Multiple parallel TCP streams (simulate many users) - Configurable payload size and duration - HTTP/HTTPS traffic simulation - FTP-like large file transfers - Configurable TCP window size for throughput control #### UDP Traffic - Constant bitrate (CBR) streams at specified rates (e.g., 1 Mbps, 10 Mbps, 100 Mbps) - Variable bitrate (VBR) with configurable burst patterns - Configurable packet size (64 byte small packets to 9000 byte jumbo) - Adjustable packets-per-second rate - Multi-stream generation to different destinations #### Voice (VoIP) Simulation - G.711 profile: 64 kbps, 160 byte payload, 20ms interval, UDP - G.729 profile: 8 kbps, 20 byte payload, 20ms interval, UDP - RTP-like headers with sequence numbers and timestamps - Simulate multiple concurrent calls (e.g., 50 calls = ~5 Mbps G.711) - Jitter injection for realistic voice patterns - Mark with DSCP EF (46) to test priority queue #### Video Simulation - Constant bitrate video: 2-10 Mbps sustained UDP streams - Bursty video: I-frame bursts followed by smaller P/B frames - Configurable resolution profiles (720p ~5 Mbps, 1080p ~10 Mbps, 4K ~25 Mbps) - Mark with DSCP AF41 (34) to test video queue #### Signaling / Contr
