Network Traffic Characteristics

Optimizing networks performance and improving utilization requires a detail understanding of usage behaviour, signalling, and traffic characteristics on the network. GL offers a variety of test tools to simulate real-time traffic conditions on network. One generate traffic at network layer – control its protocols and load generation patterns, or generate traffic on end-to-end devices independent of underlying network, with either of the methods supporting a variety of traffic sources. 

  • Probes for all network types – Wireless (2G, 3G, VoLTE, 4G, and WiFi), IP, T1 E1, and POTS
  • Simulate thousands of virtual users (UEs) with signalling and traffic characteristics
  • Complete automation for call establishment and traffic generation / detection process
  • Traffic Generators at Network Layer (b/w Nodes within Network Infrastructure) -
    • Control Signalling and Traffic Patterns
    • Useful to estimate implications of traffic on the network performance
    • Data Traffic, Video, Voice, SMS, Fax, Digits, and Tones
    • Data Testing –TCP/IP, UDP/IP, VoIP (SIP, RTP, RTCP), HTTP
    • Packet payload from file - HDL, PCAP
    • Video Playback over IP –H.263 & H.264
    • Audio –  almost all industry standard codec supported
    • Fax Testing over TDM and IP (Pass-thro & T.38)
    • Load Test Network with different Distribution Patterns (uniform, ramp, sawtooth, fixed, normal, step, and step-sawtooth)
    • Measure - Delay, Jitter, Packet Loss, Voice Quality (MOS, E-Model)

  • Traffic Generators at Application Layer (on End Devices) – 
    • Tests are independent of under-lying network
    • Control over the intrinsic properties of the media source and the codec
    • Data Testing – HTTP, TCP, UDP, VoIP (SIP, RTP, RTCP), Route, FTP, DNS, SMS, Email, Fax
    • Video Testing – Vary Codec, Bandwidth, Frame Rate, Latency, GoP Structure and Resolution (H.261, H.263, H.263+, H.264, MPEG, MPEG-2, MPEG-4)
    • Audio –  almost all industry standard codec supported
    • Test Voice, Video, and Data Quality of Smartphones, Handset Phones, Military Radios in dynamic tactical environments, or any device supporting audio.
    • Measure - Delay, Jitter, Packet Loss, Audio/Video Quality, Voice Quality (POLQA, PESQ, MOS, E-Model)
