Bulk Call Generators for TDM, VoIP & Wireless Networks
23rd February 2018
Welcome to another February 2018 issue of GL's Newsletter providing information and insight into our automated, scripted, multi-user, multi-protocol, high capacity Bulk Call Generators

Message Automation and Protocol Simulation (MAPS™) platform is the basis for all signaling protocols and for traffic generation - whether voice, tones, digits, fax, data, or video.  It covers legacy PSTN, next generation VoIP, and Wireless equipment, interfaces, and networks (depicted below). Interfaces can be Analog, TDM, Ethernet 10/100/1000/10,000, or Wireless.

Overview

Testing network performance with high call volume is extremely important to Wireless Carriers, Internet Service Providers, and Equipment vendors.
  • To ensure that quality of experience does not degrade with call intensity, volume, protocol, or traffic
  • That heavy loads, and stress do not degrade stability or scalability of the network, during pre- and post-deployment
  • That advanced features and services are not compromised due to call intensity or call volume
Stress and loading processes can help test and simulate worst case scenarios and provide confidence that the network will continue to function under such conditions.  Bulk Call Generators require an advanced network appliance which can generate and sustain high volume of calls with heavy traffic. If VoIP, then packets must be generated and output with high precision timing, zero packet loss and in the proper order.

Listed below are some of GL's Bulk Call Generators for various technologies: TDM, VoIP and Wireless:

TDM Platforms IP/VoIP Platforms Wireless Platforms
MAPS™ CAS, MAPS™ FXO FXS MAPS™ High Density (HD)
(SIP, SIP-I, MEGACO, MGCP, SIGTRAN, MAP, CAP, INAP, BICC)
MAPS™ High Density (HD)
(GSM, UMTS, LTE, CDMA)
MAPS™ SS7, MAPS™ ISDN RTP ToolBox™
MAPS™ MAP, CAP, INAP, BICC PacketExpert 10G™

GL's Message Automation & Protocol Simulation (MAPS™) is a protocol simulation and conformance test tool that supports a variety of protocols such as SIP, SIP I, MEGACO, MGCP, SS7, ISDN, GSM, MAP, CAS, LTE, UMTS, SS7 SIGTRAN, ISDN SIGTRAN, Diameter and others. Along with automation capability, the application gives users the unlimited ability to edit messages and control scenarios (message sequences).

MAPS™ High Density (HD) is an advanced bulk call generator used to simulate high volume calls with traffic. It is available as a special purpose 1U network appliance that is capable of high call intensity (hundreds of calls/sec) and high volume of sustained calls (tens of thousands of simultaneous calls/1U platform). This network appliance provides a modular and flexible solution to generate real voice calls using industry standard voice codecs. For comprehensive information, user can refer to the Signaling and Traffic Simulator and High-Density Traffic Generator web pages.

Applications:

  • Load PBX, Switch, Gateways/Routers
  • Test IVR, Voice Mail, VoIP phones
  • Generate/Accept tens & thousands of calls
  • Voice, Fax, Digits, Tones, Data, Video traffic generation
  • Automate Regression testing
  • Feature testing
  • Remote operation
  • Scripting: Python, TCL, CLI, TestShell, HP ALM
  • Voice, Data Quality, Quality of Service

Capacity:

The following table lists the products across TDM, IP/VoIP, and Wireless networks and the call rate performance on a multicore system. Using GL's high density network interface cards (1/10Gbps), higher call rate can be easily achieved (up to 5000 per port).

Easy to Use Bulk Call Generation Features within MAPS™

Bulk Call Simulation allows quick configurations to easily create different test scenarios with scripts and profiles. These tests can be run simultaneously or sequentially (queue up tasks in succession). In addition, the Load Generation feature further allows the bulk calls to be generated with different statistical distribution patterns such as Uniform, Ramp, Sawtooth, Fixed, Normal, Step, and Step-Sawtooth distribution.

Configure Stress/Load Testing parameters such as Call per second (CPS), Max Active Call, Minimum and Maximum Call Rates, Start Call Rates, and other parameters. Call duration also can be randomized using similar statistical distribution. Infinite number of calls can be generated by specifying ‘*' (which indicates infinite calls) for Total Calls parameter.

MAPS™ also includes extensive statistical and graphical features to help visually analyze the bulk call generation.  Several important call parameters such as Total calls, Active calls, Completed calls, Passed/ Failed calls, and Calls/sec are logged in the statistics. Graphs for Call Success Ratio, and Call Status are plotted in real-time.
