NFWare vCGNAT
Beeline KZ is a leading CSP in Kazakhstan, providing wireline and wireless services to subscribers across the country. Due to the shortage of IPv4 addresses, Beeline KZ decided to deploy the NFWare Virtual Carrier-Grade NAT for its cost-effectiveness and flexibility. The solution works on top of standard x86 servers and processes 200 Gbps on each one.

For a large operator such as Beeline, it becomes imperative that an installation that aims to process terabits of traffic at one site would be effective in terms of hardware utilization. That's why NFWare offered a highly scalable solution requiring fewer servers to process a vast amount of traffic: standard x86 servers function in an Active-Active mode and work as a unified entity. Adding and removing servers in runtime allows the service provider flexibly manage needed capacity per each site.
Challenges
  • Large-scale deployment: to reach customers across the country.
  • High capacity: uses a cluster of vCGNAT servers to process a large amount of traffic.
  • Reliability: Build the cluster with N+1 redundancy at each site so that if one of the servers in the cluster fails customer service is not impaired.
  • Scalability: Beeline KZ anticipates growth in its user base and requires a system with easy scalability to accommodate that future traffic growth.
Effects of Implementation
  • High-performance vCGNAT solution on Intel architecture servers with dual-port 100 GbE NICs providing 200 Gbps per server and 1.6 Tbps total capacity.
  • Several servers work as a unified entity, quickly scaling up and down by managing the number of servers.
  • Effective hardware utilization and flexibility of hardware components led to the cost efficiency of large-scale deployment
    NFWare resilient, high performance architecture capable of up to 1.6 Tbps of throughput
