Azure SD-WAN

Microsoft Azure Software Defined Wide Area Networks (SD-WAN) offers a network management solution for connecting Azure regions. Azure SD-WAN connects distributed workforces and networked appliances regardless of whether they are on-premises, remote, at…

Branch Office Connectivity

Large businesses are typically spread over multiple branches and so branch office connectivity is essential for operating a distributed enterprise. With traditional WAN networks, businesses found managing and optimising branch office connectivity…

Can SD WAN replace Internet VPN?

SD WAN is a good option to replace a basic internet VPN service. In many ways, SD WAN is an evolution of the standard IPSec VPN service, which is still used today to meet specific or simple requirements. IPSec remains a popular encryption security option…

Cloud-Based SD-WAN

A cloud-based Software Defined Wide Area Network (SD-WAN) solution is a network overlay that enables businesses to leverage standard cloud capabilities such as instantly available scaling and a more powerful feature set. By abstracting the network…

Cloud-Enabled SD-WAN

As the utilisation of cloud services within organisations is increasing, traditional enterprise network architectures have struggled to adapt to the changing requirements that using the cloud introduces. Software Defined Wide Area Network (SD-WAN)…

Does SD WAN use MPLS?

SD WAN technology can support MPLS as one of several types of connectivity. It is designed to be connectivity agnostic, meaning that service providers can offer support for MPLS, as well as internet service provider connectivity across 4G, 5G, and…

How SD WAN is better than MPLS

SD WAN (Software Defined Wide Area Networking) is better than MPLS (Multi Protocol Label Switching) because the technology is more in-line with the needs of almost all modern Enterprise businesses. * Note that there is always an exception to the rule and…

Network Latency

Network Latency refers to the round-trip time delay for data transmission between a source and destination within a network. This means that latency is measured from the point of initiation (e.g. a download link is clicked) to the point in which the…

Orchestration

SD-WAN orchestration is a tool that provides Software Defined Wide Area Networks with a centralised management. This central management system provides SD-WAN solutions with a single interface with the capability for automation, coordination of network…

Over the Top SD-WAN

Over the Top (OTT) Software-Defined Wide Area Network (SD-WAN) is a solution for creating a virtual overlay on top of existing network infrastructure independent of the underlying transport links. This means that OTT SD-WAN can leverage pre-existing,…

QoS (Quality of Service)

Quality of Service (QoS) is a set of techniques to manage traffic across a network in order to optimise preferential performance. These optimisations vary between solutions but may prioritise specific network traffic, critical applications or services,…

SD-WAN Path Selection

Software-Defined Wide Area Network (SD-WAN) solutions offer businesses with the capability to utilise path selection through dynamic traffic routing in order to increase network performance and reliability. SD-WAN leverages multi-path utilisation,…

Site-to-Site VPN

Site-to-Site Virtual Private Networks (VPNs) allow network infrastructures to securely connect the Local Area Network (LAN) of multiple business locations via public internet. Often referred to as a ‘tunnel’, VPNs allow for an encrypted connection…

Software Defined Perimeter

Software-Defined Perimeter (SDP) is a security framework designed to dynamically create individual connections between the network perimeter and each user/device. Developed by Cloud Security Alliance (CSA) in 2013, SDP addresses the limitations of…

Which SD WAN element can be a physical appliance?

SD WAN elements can be deployed in a physical WAN edge, virtualized server instance, or software application. The main reasons for deploying SD WAN using a physical appliance are as follows: Physical dedicated hardware appliances offer better throughput…

Who invented SD WAN?

A single individual or company did not invent SD WAN - the term 'Software Defined Wide Area Network' was referenced by Gartner in 2014. Before SD WAN, the term SDN (Software Defined Networking) was initially discussed in 2007 as a technology to separate…

Will SD WAN replace MPLS?

MPLS will remain a component of hybrid WAN architecture, but SD WAN is and will be and is the primary choice for most organizations. In the minds of most IT decision-makers, SD WAN has now firmly replaced MPLS to meet the needs of almost all Enterprise…
