High Density Mobile Traffic Simulation PacketLoad (PDA)

Overview

As traffic intensity increases, network elements within wireless network (including switches, routers, gateways and transmission) can impart various impairments such as errors, excessive delay, congestion, blocking, loss, and degrade quality. Their ability to handle huge traffic requires proper test and verification methods. Simulating high volume of mobile data traffic is extremely valuable to analyze the network elements characteristics as a function of traffic intensity and traffic type (Stateful HTTP, UDP, and PCAP Replay).

GL’s MAPS™ Server with PacketLoad appliance provides high density (up to 4 Gbps) mobile data traffic simulation for UMTS, and LTE networks. Currently, the solution offers stateful TCP/HTTP, and PCAP Replay traffic types. PacketLoad supports HTTP traffic simulation with the base requirements such as port number, server IP address, and pre-canned HTTP traffic file.

GL’s MAPS™ Server with PacketLoad module allows to encapsulate the generated packet data within GTP headers and transmit through the gateway points such as SGSN & GGSN, or SGW & PGW. It allows simultaneous simulation of multiple sessions per user to verify bearer allocation bandwidth at the end points.

PacketLoad is a 1U network appliance that includes 4 x 1GigE ports supporting total capacity of up to 4 Gbits/sec stateful packet traffic generation. MAPS™ Server system controls PacketLoad appliance through CLI with HD parameter settings in Testbed setup. At the generating end, MAPS™ can automate the process of creating UEs with different mobile traffic parameters using End user configuration files. At the receiving end, MAPS™ with Packet Load verifies the received data with the various statistics such as Total packets transmitted and received, Latency, Delay, Bandwidth, Total TCP connections Created, Successful connections, Packet loss, etc.

When UE attaches to the network for the first time, it will be assigned default bearer which remains as long as UE is attached. Default bearer is best effort service. In addition to default bearer, dedicated bearers can be established for applications which requires guaranteed QOS (i.e. Voice & Video). On successful dedicated bearer establishment, all network elements in access & packet core must ensure negotiated QOS is met. PacketLoad can be used in test the network elements by generating & validating the traffic below or above the negotiated QOS.

PacketLoad can also verify the received data with the various statistics like Total packets transmitted and received, Latency, Delay, Bandwidth, No of TCP connection created, Successful connection, Packet loss, and so on.

Applications on 3G Networks - Test Scenario 1

End-to-End testing

MAPS™ configured as RNC simulates GTP traffic in UMTS network. MAPS™ RNC simulator allows to simulate up to 20,000 UEs (per appliance) with the packet data traffic encapsulated within GTP headers. The generated packet data is transmitted through the SGSN & GGSN gateway points. At the receiving end, MAPS™ Server with Packet Load is used receive calls and verify the incoming packet data with the various statistics such as Total packets transmitted and received, Latency, Delay, Bandwidth per port, Total TCP connections created, Successful connections, Packet loss, etc.

Single Interface Testing

MAPS™ RNC (MAPS™ UMTS IuPS), + GGSN (MAPS™ UMTS Gn Gp) Servers and PacketLoad can function together to test customer’s SGSN (DUT) operation at full load under various traffic conditions, and thus perform comprehensive load testing.


Applications on 4G Networks—Test Scenario 2

End-to-End testing

MAPS™ configured as eNodeB simulates GTP traffic in LTE network. MAPS™ eNodeB simulator allows to simulate up to 20,000 UEs (per appliance) with the packet data traffic encapsulated within GTP headers. The generated packet data is transmitted through the SGW & PGW gateway points. At the receiving end, MAPS™ Server with Packet Load is used to verify the received data with the various statistics such as Total packets transmitted and received, Latency, Delay, Bandwidth per port, Total TCP connections created, Successful connections, Packet loss, etc.

Single Interface Testing

Simulated eNode +MME (MAPS™ LTE S1), PGW (MAPS™ LTE eGTP) and PacketLoad can function together to test customer’s SGW (DUT) operation at full load under various traffic conditions, and thus perform comprehensive load testing.
