The document discusses networking requirements for a customer including secure internet access, load balancing, data security, scalability, and cost reduction. It presents two options - a traditional hardware-based network with firewalls, load balancers and switches, and a software-defined network (SDN) using virtualized components and centralized control. The SDN option is estimated to provide 50-70% lower capital costs and 60-80% lower operating costs while offering benefits like simplified management, performance, and innovation. Major players in the emerging SDN market are also listed.
