Posted by Admin Kayako, Last modified by Wouter Debie on 26 April 2019 01:24 PM

We are happy to announce the availability of ByteBlower version 2.1.4 This brand new release enhances the new 2.0 experience with improved NAT reporting, additional TCP parameters and performance improvements. Here is an overview of what has changed:

Changelog 2.1.4

  • Runtime
    • Improved internal memory management while running a scenario.
  • UI
    • Fixed lay out bug in the Port View, that caused the MTU and Docked columns to be hidden.
    • The Realtime View now continues to update after closing and reopening it.
    • Hiding icons when not using DHCP or VLAN on a ByteBlower Port.
  • Reporting
    • By default, only HTML reports are generated now. PDF reports need to be enabled explicitly.

Changelog 2.1.2

  • Runtime
    • DHCP timeout overflow fixed
    • A NullpointerException was thrown when having 2 or more TCP Templates
    • In rare cases a exception was thrown during calculation of the Rx Filters
  • UI
    • Correct detection of 2.0.x servers. In previous version an c++ std::exception was thrown Now you will see incompatible version next to the server in the server-view
    • In Frame View, the layer 4 tab had no scroll bars
  • Reporting
    • Unit in the Aggregated TCP throughput was always kbps but the value was calculated according the report-setting. Now the unit will adapt accordingly the report-settings

Changelog 2.1.0

Features

  • TCP enhancements
    • User may now edit the TCP rate limitation option that restricts the application layer data rate.
    • TCP slow start threshold (ssthresh) parameter is now configurable. The default value is 65535, and can be set as high as 2147483647 infinite. As a result, TCP flows can now reach their maximum throughput much faster in high-capacity networks. The value for existing projects is not changed. See this blog post for more information.
  • Aggregate results
    • Aggregate result tables return into reports. They contain aggregate TX and RX throughput information for each port in the scenario.
    • Aggregate TX (resp. RX) throughput is defined as the combined result of all flows sent (resp. received) on that port. It is calculated over both the alive time and the active time of a port.
    • The alive time of port is the period from the start of the first flow to the end of the last flow. The active time of a port is the sum of all periods with at least one active flow. Both periods are calculated per-flow and per-direction.
    • See Knowledge Base article for more information
  • Report enhancements
    • New NAT table showing the auto-discovered NAT port translations.

Changelog

  • User interface enhancements
    • TCP rate limitation and slow start threshold are now configurable.
    • More intuitive editing of TCP duration field for both time and size based flows.
    • Added compatibility error when connecting to a 2.0.x ByteBlower server, since minor compatibility breaks were needed. If you see this message, you should update your server.
    • Flows and ports in the realtime view are now appropriately colored when in the error or warning state.
    • Columns are now automatically resized, to attain an optimal fit to display the content.
    • The Copy-Down algorithm is much faster now, which is noticeable when working with hundreds of objects.
    • Copy-Down incrementing is now possible on TCP port numbers and VLAN IDs too.
    • The first item of a table is now selected by default.
    • Adding scenarios to a batch sometimes failedĀ 
  • User interface bugfixes
    • Fixed incorrect calculation of intended load when set in bytes per second.
    • Fixed minor bug in handling of time fields (e.g. start time of a flow within a scenario).
    • Ports created by wizards have now correct names.
    • The Throughput Wizard created one flow too much in some occasions.
    • The run button was visible even if no project was open.
  • Runtime bugfixes
    • TCP Congestion Avoidance Algorithm is now applied to the HTTP server as well as the HTTP client.
    • ARP was used for multicast and broadcast destinations.
    • IPv6 gateway address was sometimes ::
  • Reporting enhancements
    • Reports contain aggregate throughput results over all transmitted and received flows on each port.
    • Improved layout and subreport titles.
    • Chart legends are now on top of each chart, for an improved lay-out.
    • Time units are shown in the report
    • Negative loss is colored pink again
