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 supports massive simulation of UEs (up to 500000) with .high density (up to 4 Gbps or 40 Gbps) mobile data traffic simulation for both UMTS, and LTE networks.

The solution 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. 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.

PacketLoad is available in following platform variants -

  • PacketLoad™ 4 x 1Gbps (PKS172) - Data Traffic Generator 1U Rack Appliance with 4 x 1Gbps NIC interfaces: total capacity of up to 4 Gbits/sec Stateful TCP/HTTP Traffic.
  • PacketLoad™ 4 x 10Gbps (PKS174) - Data Traffic Generator 2U Rack Appliance with 4 x 10Gbps NIC interfaces: total capacity of up to 40 Gbits/sec Stateful TCP/HTTP Traffic

The 1U MAPS™ Server system controls PacketLoad appliance through CLI. At the generating end, MAPS™ automates the process of creating UEs with different mobile traffic parameters. At the receiving end, MAPS™ with PacketLoad verifies the received data and provides various statistics, which include, Total packets transmitted and received, Latency, Delay, Bandwidth, Total TCP connections created, Successful connections, Packet loss, etc.
