Ethernet Throughput Calculator Net Guides, December 13, 2024December 19, 2024 Planning your network infrastructure or troubleshooting performance issues? This Ethernet Throughput Calculator helps you understand the real-world performance of your network connections. While network interfaces might be rated at specific speeds like 1 Gbps or 10 Gbps, actual throughput is often lower due to various factors like frame size, protocol overhead, and network efficiency. This tool takes these factors into account, allowing you to quickly estimate actual network performance under different conditions. Simply input your network parameters or use the convenient presets to calculate maximum frame rates, theoretical throughput, and expected real-world performance. Whether you’re sizing network infrastructure, optimizing configurations, or validating performance, this calculator provides the insights you need to make informed decisions. Ethernet Throughput Calculator Ethernet Speed: 10 Mbps 100 Mbps 1 Gbps 2.5 Gbps 5 Gbps 10 Gbps 25 Gbps 40 Gbps 100 Gbps Frame Size (bytes): Min (64) 128 256 512 1024 Max (1500) Jumbo (9000) Protocol Overhead: None UDP (8 bytes) TCP (20 bytes) TCP + IPv4 (28 bytes) TCP + IPv6 (48 bytes) Network Efficiency: % Calculate Throughput Maximum Frames per Second: – Maximum Throughput (Mbps): – Actual Throughput (Mbps): – Efficiency Loss (Mbps): – Payload per Frame (bytes): – Understanding Network Throughput Network throughput is the actual amount of data that can be transferred over an Ethernet connection in a given time period. While network interfaces are rated at specific speeds (e.g., 1 Gbps, 10 Gbps), the actual achievable throughput is typically lower due to various overheads and inefficiencies. What This Calculator Does? This calculator helps network engineers and IT professionals: Calculate maximum theoretical frames per second Determine maximum possible throughput Estimate actual throughput considering network efficiency Analyze the impact of different frame sizes and protocol overheads Understand efficiency losses in their network Key Parameters 1. Ethernet Speed Choose from standard Ethernet speeds (10 Mbps to 100 Gbps) Represents the raw bit rate of the network interface 2. Frame Size Range: 64 bytes (minimum) to 9000 bytes (jumbo frames) Common sizes: 1500 bytes: Standard maximum transmission unit (MTU) 9000 bytes: Jumbo frames for higher efficiency 64 bytes: Minimum frame size, common in VoIP 3. Protocol Overhead None: Raw Ethernet frames UDP: 8 bytes of header TCP: 20 bytes of header TCP + IPv4: 28 bytes combined TCP + IPv6: 48 bytes combined 4.
