Changelog 2.11.4 (2019-09-18)

(Linux, macOS X and Windows only)

• [Linux] Added support for Debian 10 and Ubuntu 20.04
• [Windows] Fixing GUI initialization, resolving the attribute warning in the console.

Changelog 2.11.2 (2019-03-05)

• [Windows] On some systems an unknown battery level was reported as 100%. This affected mostly Windows.
• [Android] We now support from Android 7 till Android 11. To enable logging ESSID/BSSID/RSSI we had to drop Android 6 support.
• [All] We’ve revised the FrameBlasting transmit approach. The new algorithm is better able to match the configured duration and rate, especially when the configured rate exceeds the available bandwidth. This occurs regularly in low bandwidth Wi-Fi environments, the excess bandwidth is dropped in these moments.
• [macOS] Matching Apple guidelines we only use the essential capability set. Where possible we only use coarse Location to be able to monitor ESSID/BSSID.
• [all] Fixed an issue where the device was marked as Booting Device when the device type contained a quote

Changelog 2.11.0 (2019-12-04)

• Added support to collect the WiFi interface parameters over time: SSID/BSSID/Channel/RSSI/TxRate on supported devices.

You can find the detailed installation instructions in our How to: Install the Wireless Endpoint on your device.

This page contains the changelog for version 2.11 of the ByteBlower. How to update your ByteBlower server is explained in following article:

• https://support.excentis.com/index.php?/Knowledgebase/Article/View/74/51/how-to-update-a-byteblower-server

2.11.8 (2020-06-25)

Fixes

• Fixed an issue where the performance of a 3x00 server dropped significantly on v2.11.6
• Adding timestamps to the standard output / error logs for the ByteBlower and MeetingPoint
• DHCP protocol implements the elapsed time value. DHCP servers which rely on this field for high availability will now work as expected.

2.11.6 (2020-04-15)

Fixes

• Improve the transmit time accuracy of Frame Blasting flows.
• The "Port.Create" method now works again on the ByteBlower 1200 series.
• The ByteBlowerPort's result history counters can now be consumed by multiple ByteBlowerPort objects (each ByteBlowerPort contains its own copy of the result history.)
• Configurator: IPv4 address validation failed when configuring static IP addresses on a management interface

2.11.4 (2020-02-20)

Fixes

• Fixed a bug which used unicast addresses in the DHCP requests. This could confuse some bridging devices which dropped the requests.

Misc

• To help our support engineers, we now add the server and meetingpoint version to the logs.

2.11.2 (2020-02-11)

This release primarily focusses on bugfixes.

One of the fixes changes the default behaviour of the DHCP client running on a ByteBlower Port.  The DHCP Client used the broadcast DHCP-technique to obtain its IPv4 address.  As some customers noticed, some devices flagged this DHCP traffic as a broadcast storm when performing DHCP on multiple ByteBlower Ports.  This change in the ByteBlower DHCP client changes the default DHCP technique to the unicast technique, working around the limitation imposed by these devices.  The DHCP technique (broadcast/unicast) can be configured using the ByteBlower API.

Enhancements

• Server: Added the possibility for the DHCP client to disable the BROADCAST bit in the DHCP flags.  The ByteBlowerPort will then use unicast packets when possible.
  Please note that this is now the default behaviour.  Using our API it is possible to revert to the older broadcast technique when needed.
• Server: Added extra DHCP timing statistics (timestamps when the DHCP discover/offer/request/ack, DHCPv6 solicit, advertise, request, reply are sent or received)
• MeetingPoint: Android 10 is now added to the list of supported operating systems.

Fixes

• Server: Fixed a crash when a ByteBlowerPort was being destroyed and the IGMP or MLD protocols needed to transmit messages.
• Server: Fixes for IGMPv1 and IGMPv2 where an incorrect back-off interval was used.
• Server: Fixed an issue where IGMPv1 did check the group address too much.
• Configurator: Fixed a crash when the network configuration reached an inconsistent state.
• MeetingPoint: Fixed a crash when the process got an interrupt signal

2.11.0 (2019-12-04)

Enhancements

• The meetingpoint is aware of SSID, BSSID, RSSI, WiFi Channel and WiFi transmit rate on supported devices. To use these features you will also need to update the Wireless Endpoint on the device and the ByteBlower API installed  on your computer
• The 24 port NBASE-T swtich for ByteBlower has been added to the byteblower-configurator. This makes it much easier tconfigure it.
• Unsupported Operating Systems and devices can be registered at the MeetingPoint. This makes them available for test-runs. To make it clear that we've not yet tuned our code for the system we do add the 'unsupported' to the name of the device.

Fixes

• When requesting the result history on a Wireless Endpoint, all results were returned instead of only the new ones.  This resulted in growing histories (and thus memory usage) over time.
• Improve TCP performance for flows that have a high number of packets in flight.
• Fix packet duplication in Streams that have a small number of frames configured.

JSON reports: making it easy to process results in detail

You can now generate your ByteBlower reports in JSON format ! This is a beta feature, meaning that we are still actively developing it. We are already releasing this feature because we are convinced that it will bring you great benefits, even in its current state. Also, we 'd love to hear from you what you think of the JSON reports.

Enable the JSON results in the Preferences:

Remember, you can re-generate reports, using existing test data ! Click here to learn how to regenerate GUI reports

Interactive reports: getting a good grip on things

ByteBlower reports contain a lot of information. It may be difficult to interpret the graphs, especially in the case of large tests. Some plots appear to be stacked right over each other, hiding crucial info.

While we can't make your screen any larger, we can help you identify the events that matter.

This new release transforms all 6 results over time into interactive graphs. You can zoom in on them, hide plots you are not interested in and easily read the exact value at each point. An example of the new reports:

New tests use this interactive format by default, but we haven't forgotten your old results. Do you have an archived report you couldn't quite make sense of? You can regenerate it now in the report and inspect it in more depth.

Click here to see our Knowledge Base article about how to regenerate GUI reports.

Capture

When running tests, you often want a capture to investigate what is happening on your DUT/setup. You can now capture on the traffic ports through the GUI. Simply click to start the capture and all data is saved directly onto your hard drive; it's just a matter of opening Wireshark to start debugging. Below is an animated gif that shows how it's done:

Server Update Wizard

Updating your ByteBlower Server is now easier than ever! Even servers that have no direct connection with the internet can now be updated via the GUI. The new Server Update Wizard is available in the Server View. Here’s how it works:

Reports from a stopped CLT

Stopping the ByteBlower CLT used to be a tricky process. The only way to do it was through control-c, but this leaves you without a report. It is also annoying, especially when working with headless systems.
As of this release, you can now restart the ByteBlower-CLT with the regenerate option. The CLT will then regenerate the last report. It generates all available report types by default, but it also accepts a list of format types.

What's coming next?

The next version is already in the works and will be released in the next few months. Some of the new features you can expect:

• Wi-Fi details (RSSI/BSSID/...) in API where available
• JSON reports preview

You can download this version of the GUI here: https://setup.byteblower.com/software.html#GUI

Information on how to use the CLT version of the GUI: Introduction to ByteBlower CLT

Changelog 2.11.8

New Features

• [Reporting] JSON reports.

Bug fixes

• Initializing test-runs with many frames goes faster. The 'improving filter' requests less info from the ByteBlower server

Changelog 2.11.6

Bug fixes

• The TCP goodput (or Layer 5) rate was handled differently than all other results over tine. This caused artifacts in the Report. Everything is the same now, thus fixing the artifacts.
• Frames below the minimum 60 bytes are padded before transmitting.

New Features

• [Reporting] JSON reports. (beta feature)

Changelog 2.11.4

Bug fixes

• [Meeting Point]: When a single Wireless Endpoint returns corrupt information, the MeetingPoint keeps refreshing now.
• [UI]: The GUI is more lenient now regarding allowed IPv6 address format.
• [Reporting]: The CSV report didn't always include the OOS results over time. They do now.
• [Reporting]: Cleanup of the CSV format. Not all sections used the same title format (TCP Info, TCP results over time, HTTP Results overtime), added a newline as a separator between HTTP and TCP results over time.
• [UI] Due to miscalculation, the IPv6 traffic class was limited to 0x80
• [CLT] The CLT now uses up to 1Gbyte of heap-space, just the same the ByteBlower GUI. This avoids the CLT going out of memory where the GUI succeeds.
• [UI] Only show valid battery levels.
• [UI] You can now also use the support tool or update a ByteBlower server that isn't running.
• [Reporting] The time-axis correctly counts the days in multiday tests
• Fixed nullpointer exception that happened when a test was cancelled promptly after being started.
• [Reporting] Fixed the Aggregate Tcp charts on MacOs. The embedded browser had difficulties with the minified script.
• [Reporting] The first sample of the Latency distribution wasn't shown.
• [Reporting] In the CSV output we've restored the headers and documentation of the "Out Of Sequence overview results table" and "Latency overview results table".

New Features

• [UI] The GUI report lists the configured duration of a FrameBlasting flow.
• [UI] The units are displayed on the time-axis in the graphical report
• [UI] The title of the FrameBlasting charts now shows source and destination
• [UI] The Hex text fields in the FrameView are easier to use. You don't need to fill in the leading zeros anymore.
• [UI] The edit button in the FrameBlasting View is disabled when the template has no frames.
• [Reporting] Reduced memory consumption when generating the HTML report.
• [Reporting] The FrameBlasting tables show all frame sizes even when multiple sizes are configured.

Changelog 2.11.2

Bug fixes

• [Reporting]: Fixed Frame Blasting Throughput results over time in CSV reports.

Changelog 2.11.0

New Features

• [Reporting]: Interactive graphs.
• [Server View]: You can now capture network traffic from the popup menu in the Server View.
• [Server View]: Updating a server is now easier than ever. We added a new wizard explaining what will be done. We made it more robust and usable in various lab networks.
• [General]: The currently open project is saved regularly now. You can open the most recent project from the file menu.
• [CLT]: Added an option to regenerate the report on the latest CLT run.

Improvements

• [Archive View]: When new reports are generated, they will now immediately become visible in the table.
• [About box]: Third-party libraries used have been documented. You can find them in our legal info for ByteBlower plug-ins.
• [General]: Reduced number of API calls to the ByteBlower Server for TCP tests. This will particularly benefit larger tests.
• [General]: NAT entries are kept live until right before the start of the test.

Bug fixes

• [General]: The scenario isn’t stopped when the same server or meeting point is accessed from multiple FQDNs.
• [Archive View]: You can now regenerate multiple reports by selecting multiple tests.

Known issues

• [Reporting]: For Linux users, interactive charts are only visible using an external browser.

ByteBlower API 2.11.6 (2020-04-15)

Download

You can download the latest version at https://setup.byteblower.com/software.html.

Enhancements

• Added support for python 3.7 and Windows 64 bits.

Fixes

• The red 'evaluation license' message has been fixed. Due to a build error the (TCL) installers were created with an evaluation version of BitRock.

ByteBlower API 2.11.4

This API version was not released, this is a ByteBlower Server release only.

ByteBlower API 2.11.2 (2020-02-11)

Download

You can download the latest version at https://setup.byteblower.com/software.html.

Enhancements

• Added the possibility to configure the BROADCAST/UNICAST DHCP flag.  The ByteBlower Port will use this in the DHCP Process
• Added extra DHCP timing statistics (timestamps when the DHCP discover/offer/request/ack, DHCPv6 solicit, advertise, request, reply are sent or received)

Fixes

• When Refresh was called on an OutOfSequence trigger, the result information was invalidated.  Accessing this information caused a crash of the API.
• When the DHCPv6 Session Information was requested, the actual information was not requested on the server, thus needing an extra Refresh call.  This inconsistency with the other parts of the API is fixed.

ByteBlower API 2.11.0 (2019-12-04)

Download

You can download the latest version at https://setup.byteblower.com/software.html.

Enhancements

• Added support for the Wireless Endpoint to collect network information over time.

Fixes

• TCL: The signature for the deprecated method Pcap.Save on our Rx.Capture.Basic was wrong and resulted in an error.
• TCL: The NetworkInfo object on a Wireless Endpoint can now be Refreshed.
• Fixed an issue where it was impossible to fetch the Result History for a Frame configured on a Wireless Endpoint.

Misc

• Our Python API (beta) is now available as a Python wheel instead of using a custom installer.  This gives us the possibility to release them later using PyPi

In the summer of 2018, we’ve introduced the option to automatically restart a broken TCP session. This feature provided continuous TCP traffic, even when the network itself encountered hiccups. At that time, this feature was only available on the ByteBlower server ports. In this first major release of 2019, we are bringing this feature to ByteBlower Wireless Endpoints. A big aid to test mobile devices even in difficult Wi-Fi environments.
