INET-2.1.0 Stable Release Available

February 1, 2013

This is the latest stable version of the INET Framework. This version is now recommended for your further INET-based development. It requires OMNeT++ 4.2 or 4.3.

NEW:

  • Added a new module to model an “internet cloud”. The component can be configured to model packet delay, datarate and drop probability between each input-output interface pair. The parameter matrix is provided as an XML configuration file. See the README file in src/nodes/internetcloud for further details.

  • New SimpleVoIPReceiver/Sender applications that gather MOS (Mean Opinion Score) for measuring voice quality.

  • Added HNA support to the Batman protocol (MANET)

CHANGED:

Applications:

  • PingApp: Shows the configured destination address at the end of the simulation.

  • TCPBasicClientApp: bugfix #611: simulation generated an ASSERT if numRequestsPerSession parameter value larger than 1.

  • TcpApp: socket state is now shown on the GUI (in Echo, Sink and Session apps.)

  • VoipTool: was renamed to VoIPStream (The actual module names are VoIPStreamSender/Receiver.)

Ethernet:

  • Transmission channel’s ‘disabled’ parameter is now correctly handled in EtherMacBase.

Ieee80211Mac:

  • Better parameter processing in MAC: error is thrown if an undefined value is specified for the opmode or autoBitrate parameters.

  • Added the Ieee80211Descriptor class to assign modulation speed and type for the different opModes.

  • Bugfix: Default bitrate for opMode ‘p’ was incorrectly set.

BGP:

  • Minor optimizations

  • Bugfix: The text in specification “sets the ConnectRetryTimer to zero” means: restart this timer. The _connectRetryTime member now stores the timeout value.

Manetrouting:

  • updated documentation

  • replaced Uint128 with ManetNetworkAddress

  • removed:

    • unused ManetTimer and BatmanTimer class

    • unused static variables

    • isIpLocalAddress(), uses isLocalAddress()

    • convertAddressToString()

    • getXPos(), getYPos() functions, you should use getPosition() instead.

  • redesigned coordinate and speed storage and access. replaced double x,y with a Coord. getDirection() now returns the speed vector (as a Coord)

  • getters returns UNSPECIFIED_ADDRESS if addrType==UNDEFINED

  • merged sendToIp() code into a common base function sendToIpOnIface()

AODV:

  • AODV’s hand-written descriptors were replaced with generated ones.

  • aodv_msg_struct.h: added getter methods expected by the generated descriptors removed hand-written aodv_msg_struct_descriptor.cc

Batman:

  • Updated and expanded documentation

  • Updated the code to match the latest available “batmand” version.

  • Numerous optimizations

  • Fixed several memory leaks

  • Fixed routing table corruption and possible crash when multiple radios were used in a single host

  • Fixed decapsulation of incoming packets. Now it checks for the type of decapsulated packet.

  • Fix for a problem when aggregated batman packets were dropped erronously.

  • Added HNA support. Nodes can advertise external networks, so traffic towards those networks can be routed correctly. Use the announcedNetworks parameter to specify multiple connected external networks.

  • Added SourceModifier script to help the conversion from the original batmand code.

    • fixes spaces, tabs and empty lines

    • replaces some c-style structs to c++-style classes

    • replaces some batmand specified list manipulators with c++ code

    • replaces malloc/free with new/delete

    • removes prof_start()/prof_stop() calls

Examples:

  • Added a new simulation with wired and wireless hosts exchanging UDP data via an AccessPoint. It shows how to use the IPv4NetworkConfigurator to mix wired and wireless networks.

  • Fixes for BGP examples.

  • New example to demonstrate HNA support in Batman.

  • Hostautoconf examample moved to the adhoc folder.

Other changes:

  • Uint128 class was removed. Use ManetNetworkAddress class instead.

  • Visual changes in StandardHost/NodeBase: utility module icons are now smaller and wlan[]/PingApp[] modules are displayed in a row.

  • NodeBase: it is possible to use mobility module even if numRadios = 0

  • Added check for detecting too small netmask parameter value in HostAutoConfigurator

  • PacketDump: TCP header option fix (dumped only in verbose mode.)

  • Bugfix #620. The module pointer returned by a ModuleAccess class is now cached only if get() was used. For get(module) no caching is done.

  • MACAddress: made the constructor explicit so we will not see unexpected implicit conversions in future

  • IPv6Address: removed Uint128 related functions and added an additional constructMask() method

  • headerserializers: compile fix for Visual C++ 10.0 and later

  • Pcap now records on ALL interfaces by default (including external IFs). Added Enter_Method for better error reporting if a packet cannot be serialized. Also added an icon for PcapRecorder.

  • Several TCP related fixes.
