A solution for CSPs that use a power of synergy between SDN and NFV to provide high-performance NAT/PAT functions.
The solution architecture consists of following components:
B4N NAT VNF: a set of VMs that converts the L3-L7 information according to specified ALG algorithms
B4N Orchestrator: provides service delivery, unified management and monitoring functions
Failover cluster of B4N Controllers: controls L3-L4 address translations and performs traffic management
Distributed Switches: provide L2-L4 header modifications, traffic load balancing between B4N NAT virtual service machines and collect statistic information
