GL Communications Inc. has announced its latest product: a high-density GTP traffic simulator, referred to as “PacketLoad,” which is used for simulation of high-volume mobile data traffic (or user-plane traffic) over LTE, UMTS, and GPRS networks.

GL’s PacketLoad is a high-density packet-traffic-generation module that generates stateful TCP/HTTP, UDP, and PCAP replay traffic and provides real-world traffic conditions in the lab. It is a 1U network appliance that includes 4 x 1 GigE Ethernet ports supporting total capacity of up to 4-Gb/s stateful packet traffic generation.

Jagdish Vadalia, a senior manager of product development at the company, said, “As traffic intensity increases, network elements within wireless networks (including switches, routers, gateways and transmission) can impart various impairments: errors, excessive delay, congestion, blocking, loss, and degrade quality.”

He added that simulating high-volume mobile data traffic is valuable for analyzing the network-element characteristics as a function of traffic intensity and traffic type (for example, voice, fax, data, or video).

“For such a test requirement,” he said, “we can now use GL’s PacketLoad network appliance that works with MAPS signaling and traffic simulator software to generate a high volume of Mobile GTP and packet traffic (up to 4 G/s) over any Wireless network (LTE, UMTS, and GPRS).”
