Posted by Admin Kayako, Last modified by Wouter Debie on 29 June 2017 09:54 AM

We are pleased to announce the immediate release of a new version of the ByteBlower Tcl API.


  • ByteBlower Lower Layer API
    • Added method to set the number of packets in an ICMP Echo loop.
    • Adding method to set the TTL/HopLimit on an ICMP session.
    • Throwing a RuntimeException when trying to add the VLAN protocol on a server which doesn't support VLANs yet.
    • The statistics on an ICMPv6 session can now be cleared.
    • All unnecessary methods are now hidden in the library, which minimises name collisions.
    • Fixed bug in HttpClient where Capture.Get failed.
    • Added support for Frame Tags ( SequenceTag for out-of-sequence detection and TimeTag for latency measurements), and their structure, format and position within the frame.
    • Added support for configuring DHCPv6 timing parameters.
    • Added support for static methods.
    • Added support for RTCP inbound and outbound captures.
  • ByteBlower Higher Layer API
    • Added global and function-level documentation to the ExecuteScenario file, describing the purpose and syntax of the ByteBlowerHL.
    • Cleanup of the ExecuteScenario file, with consistent syntax, parameter naming and indentation.
    • Recreated an old ByteBlowerHL scenario for latency detection (flowlatency).
    • Added a ByteBlowerHL scenario for out of sequence detection (flowoutofsequence).
  • Example scripts
    • New TCP over IPv6 example script.
    • New latency and out-of-sequence detection example scripts, which use the new Higher Layer API scenarios.
    • Added an echo reply timeout parameter to the ICMPv6 example script.
    • Removed an old and duplicate ICMPv6 example script.
    • Changed various multicast example scripts to have consistent relations between the script files.
    • Cleanup of general.proc file, with consistent syntax, indentation and documentation.
    • The general.proc flow creation functions now support latency and/or out of sequence detection. The default usage creates a normal trigger, just like before.
  • Installer
    • Made the window a bit wider, so the overview text on the last page can be shown completely if all components are selected.
