TCP Throughput Calculator
Based on the Mathis et al. formula: throughput ≤ (MSS/RTT) × (C/√Loss) where C=1
Bandwidth-Delay Product (BDP) Calculator
Calculate the amount of data that can be in transit on a network connection at any given time.
BDP = Bandwidth × RTT
TCP Window Size Calculator
Calculate the required TCP receive window size to fully utilize a link.
Window ≥ Bandwidth × RTT
UDP Throughput Calculator
UDP is connectionless and has no flow control or congestion control. Maximum throughput is typically limited only by available bandwidth.
MTU/MSS Calculator
Calculate optimal MTU and MSS values for network configuration.
MSS = MTU - 40 (TCP+IP headers)
Packet Transit Time Calculator
Calculate how long it takes for a packet to traverse a network link.
Network Latency Calculator
Estimate end-to-end latency based on hops, distance, and processing delays.
Bandwidth Converter
Convert between different bandwidth units.
IPv4 Subnet Calculator
Calculate subnet details from IP and CIDR prefix.
QoS/DSCP Mapping Calculator
Map between DSCP, IP Precedence, ToS, and 802.1p (CoS) values.
Protocol Overhead Calculator
Calculate protocol overhead for different layer 2/3/4 encapsulations.
IP Fragmentation Calculator
Calculate how an IP packet gets fragmented across different MTUs.
Jitter Calculator
Estimate jitter impact on voice/video quality. Jitter is the variation in packet delay.
