Message Automation and Protocol Simulation (MAPS™)

31

About MAPS™

 MAPS stands for Message

Automation and Protocol Simulation

 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

• ut-of-the-box scripts that act as

fully functional state machines for the relevant protocol.

32

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

• f 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

MAPS™ Working Principle

35

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

37

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.
