ZTE Smart Service Chain Solution

  • With rapid development of mobile Internet and the increasing revenue proportion of data services, the focus of operators has begun to shift from voice value-added service to data network value-added service. The ZTE SSC solution provides end users with data network value-added services to help operators increase ARPU.
  • In general, ZTE's smart service chain includes three parts: direct routing load balance, convergent SF and congestion awareness & analysis.
    1. Direct routing load balance provides front-end load balancing for SFs. 
    2. Convergent SF provides functions such as traffic classifier, stream optimization, URL filtering, virtual firewall and CGNAT.
    - Traffic classifier matches the traffic with the service chain through traffic identification; 
    - Stream optimization optimizes TCP traffic and QUIC traffic to reduce network latency, improve network bandwidth and improve user experience;
    - URL filtering filters out specified data such as vulgar information and malicious websites based on the URL of the user's Internet browsing, to help operators improve users' Web browsing experiences; 
    - Virtual firewall realizes abstraction and virtualization of firewall resources, and provides network security for core network, to help operators improve network security;
    - CGNAT provides functions such as SNAT and ALG to relieve the pressure of the operator's IPv4 address shortage.

    3. Congestion awareness & analysis can grasp the congestion status of wireless network rapidly, and provide a decision basis for traffic optimization.
