Tessabyte vs PacketCircle

Experience the difference with Tessabyte — a powerful tool for measuring and analyzing network performance. This utility sends TCP and UDP data streams across your network and computes important metrics such as upstream and downstream throughput, packet loss, jitter, and round-trip time, and displays the results in both numeric and chart formats. Whether you're troubleshooting connectivity issues, validating upgrades, or optimizing your network, Tessabyte provides precise insights into its speed and reliability. Tessabyte uses a client-server setup to run tests, so a server component (which can be downloaded at https://www.netmantics.com) is highly recommended for local network testing. However, the application also offers access to public test servers. What can you do with Tessabyte? • Wi-Fi Speed Tests: Test wireless networks for throughput and reliability. • Network Capacity Tests: Assess the maximum data transfer rate that a network link can support. • Link Quality Analysis: Determine the quality of individual network links. • Stress Tests: Simulate high traffic loads and observe how the network behaves under congestion. • Quality of Service (QoS) Assessment: Evaluate how different traffic types are prioritized in the network. • Firmware and Hardware Updates Validation: Verify the impact of network device firmware or hardware upgrades. • LAN Bandwidth Tests: Don't take your local network speed for granted. Test, verify, and monitor. • Network Topology Planning: Understand how network design choices impact performance. • Comparative Benchmarking: Compare the performance of different network components or analyze how your network behaves at various times of the day. • Security Assessment: Evaluate the impact of security measures on network performance. • Load Balancing Verification: Test the effectiveness of load balancing in a network. • SLA Compliance Verification: Ensure that the network meets its Service Level Agreements. Why Tessabyte: • Accurate, real-time measurements • Reports in PDF and CSV formats • Customizable TCP and UDP traffic parameters • Support for both IPv4 and IPv6 • Cross-platform compatibility: an iOS/iPadOS client can "talk" to a macOS or Windows server, etc.

PacketCircle turns packet captures into a clear picture of who is talking to whom. Instead of scrolling endless packet lists, you see communication pairs as an interactive circle: endpoints on the rim, conversations as edges, colors by protocol or session quality. Ideal when you need to understand a capture quickly — on site, in a meeting, or reviewing a file someone sent you. What you can do • Open PCAP and PCAPNG captures • Explore Top talkers on a circle, table, or gauges view • Filter by protocol and focus on the conversations that matter • Inspect session health, ports/services, and application hints • Jump into a Wireshark-style decode (packet list, protocol tree, hex) • Follow TCP streams and export a conversation as PCAP Built for analysis, not noise PacketCircle is a native iOS app with a shared engine designed for conversation-centric troubleshooting — DNS, HTTP, TLS, SMB, and more when the payload is visible — without requiring Wireshark on your phone. Open a capture. See the circle. Understand the network. Made with love for the packet community.
