IT professionals across the board are facing the limitations of legacy, hardware-based networking. This is particularly true for distributed enterprise environments. But while software-defined networking (SDN) and virtualized networking are beginning to bring big rewards for data centers, a new white paper argues that most current solutions do not account for the special needs of local area network (LAN) and wide area network (WAN) edge environments. The paper from Netsocket lays out an alternate networking framework optimized for enterprise, campus, branch, and edge environments.
The white paper, “Netsocket Virtual Network (NVN) for Distributed Enterprises,” looks at Netsocket’s answer to SDN for the edge. According to Netsocket, NVN can reap capex savings up to 3:1 and opex savings of 5:1 over single-purpose, hardware-based legacy networking solutions. The white paper, free to SDNCentral members, examines:
- Challenges facing traditional distributed enterprise networks
- How network virtualization is leaving the distributed enterprise behind
- Business benefits of Netsocket’s approach
- Benefits to managed service providers of enterprise networks
The white paper compares NVN to a legacy-routed network for a sample 50-site company. This company’s network is composed of multiple interconnected sites whose user and device capacity can vary by several orders of magnitude, and an edge router connects sites to each other through off-site WAN services (e.g. Internet or MPLS) provided by a separate service provider.
The NVN solution virtualizes all networking functions including routing, Layer 2/Layer 3 switching, firewalls, and tunnels — allowing them to be hosted on commodity x86 hypervisor-enabled servers at each site. The same servers may be used to host other site-virtualized applications as well.
In this comparison, regardless of whether the enterprise network is managed by in-house staff or a managed service provider, the paper argues the Netsocket approach drastically reduces both networking capex and opex, resulting in a 4:1 savings in total cost of ownership (TCO) over legacy edge-network solutions.
