High Volume Mobile Data Traffic Generation
over LTE, UMTS, & GPRS Networks
7th, Feb 2020
Welcome to the latest issue of GL's Newsletter providing information and insight into our High Density GTP Traffic Simulator referred to as PacketLoad, which can simulate massive number ofsubscribers (up to 500,000) and high density of mobile data traffic (up to 40 Gbps) to easily stress or load test 3G/4G networks.
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 degraded 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 (e.g. Voice, Fax, Data, Video).
For such a test requirement, we can now use GL's MAPS™ Server with PacketLoad appliance. 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 signalling and traffic parameters.
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 creating 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.
