PacketLoad™ - High Density Mobile Traffic Simulation

Welcome to another GL Communications' newsletter providing information and insight about our high density mobile traffic generator referred to as PacketLoad™, the appliance supports massive simulation of UEs (up to 500,000) with high density (up to 4 Gbps or 40 Gbps) mobile data traffic simulation for both UMTS, LTE and 5G networks.



GL’s PacketLoad™ module is a high density stateful TCP/HTTP, UDP, and PCAP Replay traffic test solution providing "real-world" traffic. The appliance can generate massive number of UEs (up to 500,000) along with a high volume of mobile GTP-C (control plane), GTP-U (user plane) and packet traffic for up to 4 Gbps or 40 Gbps to load test or stress test core UMTS/LTE networks.

One of the important features of the appliance is its ability to allow different combinations of TCP/HTTP and UDP traffic combined with PCAP Replay to be simulated from both ends of the network. This helps to evaluate end-to-end core network performance with variable signaling and traffic parameters.

PacketLoad™ is 1U network appliance available in two variants

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

Operational Capability

The MAPS™ Server with PacketLoad solution offers high density stateful TCP/HTTP, and PCAP Replay traffic types. It encapsulates the generated packet data within GTP headers and transmits through gateways such as SGSN and GGSN, or SGW and PGW.

The appliance works with MAPS™ LTE S1, MAPS™ LTE eGTP-c, MAPS™ UMTS Gn Gp, MAPS™ IuPS applications. The 1U MAPS™ Server system controls the PacketLoad appliance through CLI.

At the generating end, MAPS™ automates the process of simulating UEs with different mobile traffic parameters. At the receiving end, MAPS™ with PacketLoad verifies the received data and provides various statistics, which include the total packets transmitted and received, latency, delay, bandwidth, total TCP connections created, successful connections, packet loss, and more.
