Challenges

  • Proactively mitigate risks to the customer experience
  • Optimize LTE network and reduce QoS impact by detecting traffic bursts
  • Locate bottlenecks to improve overall network capacity
  • Immediately identify and correct any network misconfigurations
  • Optimize fault failover to eliminate downtime

Benefits

  • Ability to predict and mitigate future failures
  • Tools to proactively assure and optimize QoS and QoE even under adverse conditions 
  • Per-flow measurements for microsecond precision
  • Ultra-granular sub-second sampling
  • One-way measurements
  • Integration into existing management and orchestration systems
“Our definition of success in SDN and NFV deployments is to use a wide range of hardware instead of vendor-specific appliances, while remaining heavily focused on QoS and QoE—Quality of Experience—for the customer. To reach that level of network traffic sophistication you have to have analytics in place to understand what is going to happen in your network, track and analyze this data, and use it to provide and manage QoS.”

    3G

    Third Generation
    A cellular network that uses third-generation wireless technology based on standards that support wireless voice telephony, mobile and fixed internet access, video calls, and mobile TV. Such networks are capable of data transfer rates of at least 200 Kbps and as fast as 21 Mbps.

    3GPP

    Third Generation Partnership Project
    International collaboration among telecommunications associations, with the purpose of developing and maintaining the Global System for Mobile Communications (GSM) specification for 3G mobile networks.

    4G

    Fourth Generation
    A cellular network that uses fourth generation wireless technology to deliver mobile broadband internet access in addition to voice and text messaging. Two synonymous 4G systems are commercially deployed: Mobile WiMAX an Long Term Evolution (LTE). LTE is the predominant system in the U.S.
