TCP&UDP测试工具 1.027

TCP&UDP测试工具 is a lightweight, practical utility for exercising and validating TCP and UDP communications. It helps you spin up quick client or server endpoints, send custom payloads, observe responses in real time, and verify connectivity through firewalls, NAT, or across local networks.

Key features:

• TCP client/server and UDP sender/receiver modes
• Multiple concurrent connections/sockets
• Custom payloads in text or hex, with optional CR/LF and user-defined delimiters
• Adjustable send interval, packet size, and burst/periodic transmission
• Real-time receive window with timestamps, source address, and length
• Hex/ASCII display and optional auto-save of logs
• Basic traffic statistics (bytes, packets, rates) to aid throughput checks
• Support for IPv4/IPv6 and local IP/port binding
• UDP broadcast and basic multicast reception where supported

Typical uses:

• Validating port reachability and firewall rules
• Simulating devices or services during development and QA
• Measuring basic throughput and exercising socket behavior
• Classroom and lab demonstrations of TCP/UDP fundamentals

Notes:

• Some networks require administrator privileges or firewall exceptions.
• Use only on networks and endpoints you are authorized to test.
