Subject: [Lanforge] LANforege 5.0.5 is released.
Message-ID: <475750F9.2050509@candelatech.com>

Hello!

We are proud to present the latest LANforge release version 5.0.5.X

This release contains significant improvements to SIP call generation,
wireless client emulation, reporting, and network emulation.

The full release notes since 5.0.3 are listed below.  (5.0.4 had a few
annoying bugs, so we skipped on past it for 5.0.5).

Release 5.0.5.1

     *  Fix GUI bug with drag-selecting rows in tables in the GUI.

     *  Fix Server bug with setting default GW in ports only associated with VRs.

     *  Fix Server bug with Layer-3 endpoints where after Quiesce, the endpoint
        could not be started again.

     *  Fix bug where GUI didn't request updates if the remote resource had it's
        clock set incorrectly.

Release 5.0.5
     *  Start using Java 1.6.0_3 instead of older 1.5.0_7 for
        LANforge-GUI.  Add 'sed' hack to make Java work on Fedora 8:
        sed -i 's/XINERAMA/FAKEEXTN/g' jre1.6.0_03/lib/i386/xawt/libmawt.so

     *  Fix bug with GUI detection of kernel-mode WanLink Support.

     *  Fix bug that did not allow a Port's gateway to be modified
        without also modifying the IP or MASK.

     *  Fix bug that caused cx-drops to not be reported for VOIP/RTP
        endpoints.

     *  Small optimization to creating large numbers of virtual interfaces.

     *  Other less critical bug fixes.

Release 5.0.4
     *  Support Collision Domains (CDs).  CDs are groups of WanLinks
        that are contending for bandwidth on the same network.  This
        can be used to better emulate wireless networks and other
        shared-medium networks.  Support for military radio emulation
        (HNW, NCW, terrain emulation, and mobility scenarios are coming
        soon!  Contact your sales representative if you have interest
        in these features).

     *  Support up to 127 virtual WiFi stations.

     *  Support WPA (wpa_supplicant) for WiFi.

     *  Fix WiFi ath0 lockup due to getting into 'carrier off' state.
        Thanks to Aplicaziones for helping find this and other wifi
        & reporting bugs.

     *  Work-around WiFi hang with single slower-speed UDP connection
        by forcing tx-buffer size to always be large enough to fill the 199
        buffers in the wifi driver.

     *  Add Port speed and WiFi status to Port-Mgr table for easier viewing
        of WiFi state.

     *  Support spanning-tree protocol for bridge devices.

     *  Support OSPF routing protocol using the Xorp router program.
        To enable, modify the VirtualRouters in Netsmith and select
        the 'Use-OSPF' checkbox.  You should be running the version of
        Xorp from the Candela downloads page, but the latest Xorp code
        from their CVS site may also work.

     *  Work on reporting & Rate control:
        *  The old code was off by around 2% for it's rate calculations for
           some speeds & packet sizes, causing LANforge to generate slightly
           less than requested.  The same general mistake could cause a bit
           of bursty sends as well.  Both problems have been fixed, generally
           giving accuracy of around 0.1% when the network and hardware can
           keep up.

        *  Time-stamp report .CSV files with remote LANforge machine's timestamp
           instead of the GUI machine's timestamp.  This increases accuracy of
           the reports and fixes a few spikes in the generated graphs.

        *  Remove some bogus smoothing logic from the LANforge GUI when generating
           reports.  The new logic is more efficient and does not have the small
           rounding errors found in the old code.

        *  The server now keeps 3-second running averages for most protocols,
           and the GUI will graph them for the tx-bits-per-second and
           rx-bits-per-second graphs.

        *  Add global statistics (packets/bytes read/written, calls in progress,
           etc.

     *  Fix several problems with VOIP SIP message retransmission.
        SIP calls should now run much better over poor networks.

     *  Use absolute jitter (instead of allowing negative jitter).  Change
        reporting resulution to 1ms logarithmic scale from 5ms.

     *  There is a bug that affects certain high, but not too high speed,
        UDP connections on Virtual STA (WiFi) interfaces.  Automated
        workaround added:  If the user does not specify a tx-queue size,
        then it will default to 1,000,000 for UDP connections on STA
        interfaces.

     *  Added scroll-pane to GUI ReportMgr screen to fix problem where
        a long file name made buttons inaccessable.

Thanks,
Ben
