GUI 2.21

Experience Enhanced Flexibility

Unlock a host of powerful features designed to enhance your testing experience. ByteBlower GUI 2.21 brings a range of improvements, especially for ByteBlower Endpoint users. It empowers you with Heartbeating mode, real-time results, flexible TPID configuration, ipv6 firewall traversal, and more!

Important Note: For optimal performance and compatibility, we strongly advise using "ByteBlower GUI 2.21" in conjunction with "ByteBlower Server 2.21," "MeetingPoint 2.21," and "ByteBlower Endpoint 2.21."

With the all-new ByteBlower 2.21 release, you are all set to get your hands on these exciting new features.

Heartbeating Mode for EndPoint

Introducing Heartbeating Mode: Maintain seamless contact with ByteBlower Endpoints by sending regular heartbeats after specified intervals through the duration of the test. Enable or disable this mode via "File" -> "Project Properties" -> "Scenario" -> "Wireless Endpoints" -> "Keep contact with each ByteBlower Endpoint".

Note: Heartbeating Mode is enabled by default for new projects at a 5-second interval. Ensure manual activation for older project files.

Realtime Results for Endpoint

Experience real-time insights with ByteBlower Endpoint during active test scenarios. Ensure "Heartbeating Mode" is active before project execution for real-time ByteBlower Endpoint results.

  • For wireless endpoints, dive deeper into performance metrics on the 'Gateway' Monitor RSSI values, SSID, and BSSID in real-time, synchronized with the " Heartbeating" interval specified in settings

Stable Longer Duration Tests for Endpoint

Longer-duration tests are now more robust than ever. Traditionally, these tests necessitated substantial data transmission toward the scenario's conclusion, often causing disruptions in less stable connections.

However, with the introduction of "Heartbeating Mode," this issue is mitigated. Results from the endpoints are now transmitted at defined intervals throughout the test, significantly reducing data transmission near the end of scenarios. This enhancement assures heightened stability during extended tests, ensuring your results remain uninterrupted.

Preserved Reporting for Endpoint

Forget the worry of losing data. "Heartbeating Mode" in ByteBlower 2.21 now offers partial result reporting. Even if a device drops out, results up to the last interval are preserved. Ensure "Heartbeating Mode" is enabled for this safeguard.

Flexible TPID Configurations

Unlock the potential of Q-in-Q and diverse TPID configurations for your VLAN-tagged traffic plans. ByteBlower 2.21 now lets you effortlessly configure various common TPID types via the GUI. Ideal for scenarios involving distinct inner and outer VLANs with different TPIDs.


  • User selection of TPID is required.
  • Requires ByteBlower Server version 2.20 or later, with automatic project updates for older versions.
IPv6 Firewall Traversal

Introducing the dedicated firewall option for IPv6 traffic, addressing challenges related to downstream traffic transmission.

  • Simple Activation: Easily enable the firewall within the Ports view by selecting "Yes" in the firewall column.
  • IPv4 Parity: The IPv6 firewall functionality mirrors the behavior of NAT in IPv4, ensuring a familiar and secure experience.
Refreshed ByteBlower Reports

A refreshed reporting format awaits you right after running a new scenario. We've maintained the core features while ushering in a modern aesthetic.

  • Streamlined Unit Selection: Now, effortlessly customize your report by selecting throughput and latency units directly within the report interface, eliminating the need to navigate project settings.
  • Efficiency Boost: Beneath the surface, significant under-the-hood enhancements enhance reporting efficiency, paving the way for seamless future developments.

Note: Large-scale tests may fall back to the old version of the HTML report.

More User-Friendly than ever

Simplify your experience by ensuring that your preferences take the lead over automatic methods, all without interrupting you with runtime issues, unless absolutely necessary.

  • Multicast and Broadcast Efficiency: With NAT-enabled ByteBlower ports, Multicast and Broadcast operations now effortlessly prioritize themselves, eliminating potential bottlenecks. NAT discovery exclusively caters to Unicast traffic.
  • Conflict Resolution: In cases of layer-3 frame configuration clashes with NAT, your user-specified frame settings claim precedence, maintaining your intended configurations.
  • User-Focused HTTP request: ByteBlower 2.21 respects your choices – users can now set the HTTP request method which automatically prevails over the older automated method, putting you in control of your testing environment.
Improved visuals

We've fine-tuned the user interface to ensure a smoother and more pleasant experience.

  • Project Preferences: We've expanded the project preferences screen to offer ample space for your text, accommodating your specific needs seamlessly.
  • Streamlined Testing: The pause/resume test pop-up now boasts an improved layout for effortless interaction during testing.
  • Interactive Reports: Enjoy enhanced report readability as charts in HTML reports are now always interactive, enabling a deeper exploration of your results.
  • Effortless Report Viewing: HTML reports now open in your external browser by default, optimizing your screen real estate by removing the dedicated report area in the bottom right corner.
  • Bug-Free Navigation: A UI glitch in the drop-down menu within the Flow view has been resolved, ensuring smooth navigation throughout your testing journey.
Additional Improvements

We've made several additional improvements to enrich your testing experience:

  • Detailed Endpoint Version: ByteBlower reports now lists the ByteBlower Endpoint software version in the Ports section of your report, ensuring accurate tracking (even if it differs from the MeetingPoint version).
  • Swift Updates: We've extended the ByteBlower update download timeout from 10 to 90 seconds, minimizing update failures and ensuring a smoother update process.
  • Unified System Updates: Updating your ByteBlower System or MeetingPoint is now effortless. A simple right-click on either component in the GUI initiates an update that seamlessly covers both, ensuring a unified and hassle-free update process.
  • Effortless Project Creation: New project creation or initial startup is now more convenient, as the project name automatically defaults.
  • Error Streamlining: We've eliminated irrelevant errors in system info, decluttering your testing environment.
  • Enhanced Stability: Test runs involving ByteBlower Endpoint and the CLT (command-line tool) are now more stable, with NullPointer exceptions no longer causing test halts.
  • Expanded Reporting: CSV reports have been expanded to include IPv6 ports, providing a more comprehensive view of your test results.
  • Improved JSON Reports: JSON reports have received substantial improvements. They now incorporate configuration details and offer more comprehensive and detailed results. Additionally, server version details in the Ports section have been rectified.
  • Bug Resolution: We've addressed and resolved background errors associated with the "New Projects" window.
  • Optimized Archive View: The display for file sizes of test result databases in the Archive view has been optimized for better usability.

As part of our commitment to continuous improvement, we've replaced some features in ByteBlower GUI 2.21 with more effective alternatives to enhance your testing experience:
