In the past, MPLS was the only option for implementing a high-performance, reliable wide area network (WAN). However, this is no longer the case. Software-defined wide area networks (SD-WAN) provide an alternative designed for the modern network. Choosing the best connectivity fit comes down to many variables, including operating budget, flexibility needs, and geographic distance between remote branches and HQ.
Multiprotocol Label Switching (MPLS) is designed to direct traffic through a network via short path labels rather than network addresses. This enables traffic to be quickly and efficiently directed to its destination without costly inspection.
For an organization to take advantage of MPLS, it needs to have physical MPLS circuits installed at each of the connected sites. These circuits implement an MPLS virtual private network (VPN) between these sites, isolating their traffic from the rest of the Internet.
MPLS is a common choice for network connectivity because it provides certain benefits to an organization:
MPLS also has a number of disadvantages, mainly due to the fact that it requires physical links to be installed at an organization’s locations:
Software-defined WAN (SD-WAN) is a networking technology designed to enable an organization to implement a high-performance, reliable WAN. It accomplishes this by aggregating multiple transport media and optimally routing traffic over the available transport links, such as broadband Internet, mobile networks, and even MPLS circuits.
To an application sending traffic over an SD-WAN network, only a single network pipe is visible. Once traffic is sent to this pipe, SD-WAN will identify the application creating the traffic and apply application-specific routing policies. Based upon these policies and the current status of the available links, the traffic will be sent over the best choice of link to its destination. This approach enables an organization to ensure that high-priority and latency-sensitive applications receive the network performance that they require without wasting expensive, high-performance network bandwidth on less important traffic.
SD-WAN solutions have a number of advantages, making them a good choice for implementing a corporate WAN:
SD-WAN solutions have their disadvantages as well:
SD-WAN vs MPLS – Differences in Detail
SD-WAN and MPLS are both solutions designed to enable an organization to achieve high-performance, reliable network connectivity. However, they take very different approaches to doing so. Some key differences between MPLS and SD-WAN include:
SD-WAN and MPLS are both designed to provide reliable, high-performance, and confidential network connectivity. While both can be effective, SD-WAN is clearly superior in terms of cost, scalability, and security.
