Message Automation and Protocol Simulation (MAPS™) 30

About MAPS™  MAPS stands for M essage A utomation and P rotocol S imulation  It is a generic framework for the generation of telecommunications protocol messages and transmission of bearer traffic.  MAPS™ is built on a proprietary scripting language developed by GL Communications.  All MAPS™ products come with out-of-the-box scripts that act as fully functional state machines for the relevant protocol. 31

About MAPS™  Scripts : Scripts act as the state- machine, or engine for a given call. The logic of what messages to send when is all contained in a script.  Messages : MAPS has an inventory of generic Message Templates (ex: Invite.txt) which it loads from the hard drive when transmitting an actual message. Messages are completely customizable.  Profiles : Scripts and Messages are kept as generic as possible. Specific information (ex: Contact = 12345@sip.carrier.com) about a call is sourced from .xml profiles 32

Supported Protocols / Interfaces 33

MAPS™ Working Principle 34

Load Generation • Stability/Stress and Performance testing using Load Generation • Different types of Load patterns to distribute load • User can load multiple patterns for selected script • User configurable Test Duration, CPS, Maximum and Minimum Call Rate etc 35

Success Call Ratio Statistics Call Graph Call Statistics 36

Message Statistics  Message Stats provides a running tabular log of all messages transmitted, retransmitted and received during the session  Provides an easy way to monitor the reception of error responses during load generation. 37
