Overview of SD-WAN
SD-WAN also known as software-defined wide area network is a new way to approach routing in the world of cloud computing. SD-WAN uses policy-based rules to orchestrate the routing of all applications related to the cloud. It is about being simple and taking advantage of the power cloud which the old 20th-century routers were incapable of doing due to the lack of agility and flexibility. This is going to run the table over the next five years in terms of the purchase and deployment of networking worldwide. SD-WAN is more than just a software that does addressing or routing, it is the base level of the cloud networking, where it requires policy-based orchestration of full end to end services that the customers need in a network routing world – WAN optimization, visibility, access to Wi-Fi with LAN resources for routing of all point of the network.
Characteristics of the SD-WAN Network
SD-WAN offers ease to deployment, central manageability and reduced costs which are summarized by the following characteristics of the network:
- Multiple connection types, such as MPLS, frame relay and higher speed LTE wireless communications.
- Dynamic path selection, for load sharing and resiliency purposes
- A simple interface that is easy to configure and manage
- Support VPNs, and third-party services such as WAN optimization controllers, firewalls, and web gateways.
Advantages of MPLS Over SD-WAN
Despite the speed and simplicity, SD-WAN is still incapable of competing with the security and reliability of MPLS networks. Above all, MPLS remains pertinent because it complements the SD-WAN technology rather than interfering with it. Thus, companies are moving towards a more hybrid model to leverage the advantages of both these technologies, using SD WAN broadband in conjunction with their MPLS connections. An instance of this includes the necessity of MPLS for multi-location enterprise connectivity but it suffers from high costs and complexity and the implementation of SD-WAN, some of these issues can be alleviated.
MPLS to Complement SD-WAN
There is a growing strain on networks due to the adoption of third-platform technologies such as big data, analytics, cloud and mobility applications by businesses across the world. With the need for better connectivity between remote and branch employees as well as enhanced quality network services, the demand for SD-WAN will grow consequently aiding the MPLS market as well.
