Network Connectivity: MPLS or SD-WAN?

Network Connectivity Solutions & SD-WAN

Network connectivity with uptime is a difficult task.

Software-defined wide area network (SD-WAN) services have been the topic of much discussion in recent years. According to a recent report by Futuriom, the SD-WAN tools and software market will hit $4.6 billion by 2023, representing a 34% compound annual growth rate.

Behind the hype, there is, of course, a very plausible explanation. The enterprise is moving its IT and networking operations to cloud infrastructures like never before – and that means a need for agile, high-performance, and secure connections to cloud applications. SD-WAN can help.

The Managed SD-WAN Solutions from ExterNetworks offer comprehensive and cost-effective [network connectivity] from branch locations to the headquarters.

Increasing adoption of SD-WAN in Network Connectivity

As the name suggests, SD-WAN is not a network infrastructure but rather a software product that acts as an overlay to an organization’s existing infrastructure, such as Broadband Internet, Mobile 4G LTE, and so on. Due to SD-WAN’s virtual nature, however, it is not dependent on the underlying hardware. As a consequence, SD-WAN is extremely flexible. The SD-WAN intelligently redirects network traffic in real-time if there is congestion in the current network.

In addition to this, SD-WAN can handle multiple high-bandwidth WAN links simultaneously, as well as connecting to dual service providers – so naturally, performance is maximized when combining different types of connections.

In terms of security, SD-WAN is designed to be secure. Regardless of whether 0% or 100% of the network is carried on public infrastructure, encrypted end-to-end tunnels (128 bits and upwards) are built across the whole network.

MPLS is affected by this  SD-WAN network connectivity

Often, when SD-WAN is discussed, questions are raised about Multiprotocol Label Switching (MPLS). MPLS works by placing labels on packets, each label indicating the direction in which the data should be sent. The MPLS network reduces processing time at each router by setting up unidirectional routes between pairs of routers – a speed augmentation big businesses embraced twenty years ago.

Many people today use MPLS to scale their networks. MPLS enables users to create previously label-switched paths, so they can take advantage of both physical circuits, which are expensive and difficult to scale, and IP routing, which is very cost-effective.

MPLS is also attractive to enterprises due to its consistent network performance. Using classes of service, packets are classified. When networks are congested, less urgent traffic is diverted to slower routes, ensuring that the user experience is not compromised. Furthermore, by routing traffic over non-standard paths, this advanced traffic engineering can reduce congestion and latency on the previously avoided routes.

Furthermore, MPLS allows higher priority traffic to borrow capacity from lower priority streams when needed and lower priority traffic to use idle higher priority services.

Are you ready for the next step in network connectivity? 

SD-WAN’s ability to handle multiple network functions reduces both hardware and operational costs. Support for multiple underlay WAN links increases reliability and enables bandwidth aggregation and traffic separation.

With intelligent routing, network optimization can be achieved. Network devices can be deployed and managed remotely using cloud management. Taking these steps paves the way for SD-WAN technology to support the next big thing in network connectivity: wireless connectivity.

Cellular links serve as a connector option for diverse types of networks underlying Wireless WANs. These are the foundations of Wireless WANs. Thanks to SD-WAN’s network intelligence, it is easy to switch between links, separate specific traffic types, or create a new location quickly.

A wireless connection provides greater diversity, greater agility, and a broader reach to enterprise networks. The purpose is to extend the reach of enterprise networks to people, devices, and places.
