SD-WAN vs. MPLS vs. SDN– How to Choose Right Network for your Company

SD WAN vs MPLS

- The Difference in the Details
Multiprotocol Label Switching - also known as MPLS - was around before software-defined wide area networking - also known as SD-WAN - came along to provide the benefits of SDN to networking that was hardware based.
MPLS is a protocol for efficient network traffic flow that happens between two or more locations. MPLS operates in a similar way to switches and routers and is considered to be layer 2.5. Packet-forwarding technology is used to make data forwarding decisions.
SD WAN vs SDN - The Difference in the Details

It's important to know the differences between SDN and SD-WAN because while they both begin with SD, they are not the same. Their shared background in the separation of the control and data planes allow both to run on commodity x86 hardware. Both can also be virtualized.
SD-WAN provides software-defined application routing to the WAN and connecting an organization's' many locations.
SDN focuses internally within the LAN or the core network of the service provider.

SDN vs MPLS
- The Difference in the Details
An organization has to choose the right solution between MPLS and SDN, and both of these can offer your business that solution.
SDN Business Advantages
Cost Reduction
Overhead Reduction
Physical vs. Virtual Networking Management
Reduced Downtime
Central Networking Management Tool
Centralized Control
MPLS Business Advantages
One Carrier circuit can support MPLS, Internet, and SIP
Domestic MPLS takes 30 days typically to install.
Carriers provide next-gen firewall
Carrier Managed Solutions such as Firewall, VOIP, etc..
MPLS port pricing is practically the same as Internet port pricing
MPLS supports many transport types including Ethernet, Broadband, DSL
SD WAN Pros and Cons
Most people have heard of SD-WAN but don't know what it actually is. The software-defined wide-area network (SD-WAN or SDWAN) is an application of SDN technology applied to certain WAN connections such as broadband internet, 4G, LTE, or MPLS. SD-WAN connects enterprise networks over large geographic distances.
SD-WAN offers your business advantage over traditional MPLS networks. Let's take a look at some of those:
Dramatically impact the entire enterprise networking ecosystem. Geographic boundaries are erased
Visibility, scalability, performance, and control are enhanced.
SD-WAN comes with no bandwidth penalties.
Ability to cost-effectively mix and match network links according to content type or priority.
High level of security.
End-to-end encryption across the entire network, including the Internet.
All devices and endpoints are completely authenticated.
