Will SD-WAN replace MPLS.

Hi dear, we are working on your problem.

SD-WAN is the fundamental building block of WAN transformation and a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE, and broadband internet services – to securely connect users to applications.

As far as replacement is concerned, don't think I gonna happen any time soon as MPLS is being adopted almost every service provider, but yes Now operators/SP are building SDWAN setup too

Hi,
Actually, the MPLS and SD-WAN are two different technology, so, there is no saying that different technologies replace each other.
As in my opinion, with the IPv6 implemented, the SRv6 will replace the MPLS, cause the IPv6 has a good scalability, it supports extra IPv6 header to work as the MPLS, which means there is no need to use the MPLS.
While for SD-WAN, it is used to build an agile network, which works with the MPLS/SRv6 together.

Valuable information received by community members.

hello,

it is likely SD-WAN will replace MPLS but that may not be any time soon. both have their pros and cons so the choice for one over the other may be dependent on geographical distance between the networks and remote branches, operating budget, compliance requirements etc. Though SD-WAN is relatively new and comes with more improvement in user experience, security and application control tools. the main difference I see between the two is virtualization in SD-WAN and that may not easily replace an existing complex MPLS infrastructure which is tested and proven reliable. Though there seems to be a rapid shift towards SD-WAN, Hybrid deployments may last many years.
