<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong> – Advanced <strong>IMS</strong> simulation tool<br />
The IP Multimedia Subsystem (<strong>IMS</strong>) is the next generation<br />
architecture which will enable fixed/mobile convergence in all-IP<br />
network.<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong> is a powerful test tool that enables rapid<br />
development of tests for <strong>IMS</strong> infrastructure and applications. It<br />
is installed on a standard PC and is based on <strong>Linkbit</strong> Simulation<br />
Studio, <strong>Linkbit</strong>'s own simulation Integrated Development<br />
Environment.<br />
<strong>IMS</strong> <strong>Master</strong> can test both client and server components of<br />
<strong>IMS</strong> applications. It includes a wizard to graphically build SIP<br />
messages and a tool to automatically generate test sequences.<br />
Test code are auto-generated in one of five industry standard<br />
scripting languages. Creating packets with erroneous headers,<br />
sending messages out of stack order, and even implementing<br />
complete test suites is easy with the tools included in <strong>IMS</strong><br />
<strong>Master</strong>. Novices will be surprised at the simplicity afforded by<br />
the studio's helpful tools and experts will marvel at the flexibility<br />
and power of testing in their favorite scripting language.<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
allows to build<br />
Send/Receive/Wait<br />
sequences with<br />
a series of point<br />
and clicks.<br />
The script code generated by <strong>Linkbit</strong> <strong>IMS</strong><br />
<strong>Master</strong> “under the hood"<br />

Message Sequencer<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
Data Sheet LB2200<br />
The <strong>Linkbit</strong> Message Sequencer is a tool within <strong>IMS</strong> <strong>Master</strong> that allows for rapid creation of basic simulation<br />
sequences. A point-and-click interface allows the user to create test sequences without touching any of the underlying<br />
code. Users simply select one of three steps (Send, Receive, Sleep) and then follow the interactive dialogs. All the<br />
underlying code in one of five supported script languages is generated automatically and can then be used as a starting<br />
point and extended to include more demanding logic.<br />
Any trace log made with <strong>Linkbit</strong> SIP monitoring tool or Ethereal can be automatically imported, edited and replayed<br />
with message sequencer.<br />

Template Library<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
Data Sheet LB2200<br />
<strong>IMS</strong> <strong>Master</strong> includes a template library containing the entirety of messages for each supported <strong>IMS</strong> standard. Each<br />
message's corresponding data structure is described in full – including all mandatory and optional fields, data types, and<br />
value constraints. The information is presented in a user-friendly, multi-layer tree format. All fields, their types, and their<br />
constraints can be looked up instantly. Users can copy-paste templates for complete messages or individual fields<br />
directly into their scripts and <strong>IMS</strong> <strong>Master</strong> will automatically generate the necessary code.<br />

Message Wizard<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
Data Sheet LB2200<br />
The message wizard further simplifies test creation by allowing users to manipulate messages and their corresponding<br />
data structures via simple, verbose dialogs. Users select the protocol, the type of message they'd like to create and then<br />
fill out the appropriate fields while message wizard generates and initializes all needed SIP data structures “under the<br />
hood”.<br />

Debugging<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
Data Sheet LB2200<br />
Debugging is easy when you don't have to parse any messages. The <strong>IMS</strong> <strong>Master</strong> engine decodes all incoming and<br />
outgoing messages in real time. The results appear in the debug window as intuitive trees of neatly populated protocol<br />
fields. Any malformed messages will be automatically brought to the user's attention. This allows the user to concentrate<br />
on test logic and easily spot errors or other points of interest within messages.<br />

<strong>IMS</strong> <strong>Master</strong> also provides input and output methods that can be used directly in all of the supported industry standard<br />
scripting languages. So tests can be as verbose and interactive as you'd like. All script output and parsed messages are<br />
shown in order and in real time so the sequence of events is always clear.<br />

Below is an fragment of a Perl script code auto generated by <strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong>. It sends a SIP INVITE message and<br />
waits 500 msec for a response. The rest of the code (not shown) allocates and initializes INVITE_Message,<br />
UdpLayerData, and IPLayerData variables. It's auto generated by <strong>Linkbit</strong> Message Wizard.<br />
$sk->send($INVITE_Message, $UdpLayerData, $IPLayerData);<br />
if ($sk->receive($inINV = $sk->create(), 500, $sk->{SIP}))<br />
{<br />
# Handle successful reception here; message contents is available in "$inINV" variable<br />
} else<br />
{<br />
# Handle unsuccessful reception here<br />
}<br />
The same function, but in Python:<br />
sk.send(INVITE_Message, UdpLayerData, IPLayerData)<br />
<strong>Linkbit</strong> <strong>IMS</strong> <strong>Master</strong><br />
Data Sheet LB2200<br />
inINV = sk.create()<br />
if sk.receive(inINV, 500, sk.SIP):<br />
# Handle successful reception here; message contents is available in "inINV" variable<br />
pass<br />
else:<br />
# Handle unsuccessful reception here<br />
pass<br />
