software defined wide area network - explained

Businesses are always looking for ways to cut costs while increasing productivity and efficiency. Software-defined wide area networking (SD-WAN) provides both these benefits. The SD-WAN is a technology that allows you to connect multiple sites without having to buy expensive hardware in the form of physical routers. A typical router is designed to work with one specific protocol, such as TCP/IP, whereas a SD-WAN is capable of routing different protocols simultaneously. For example, a router might support L2TP/IPSec VPN connections, but a SD-WAN could do the same with Layer 3 IPsec tunnels.

Through specialized software, your traffic is directed along your network in an intelligent way that prioritizes network resources according to predefined rules. This improves the overall utilization of the network, gets your resources to users quicker and uses less bandwidth because your traffic is being intelligently sorted by software.

how an sd-wan can help your business

Managed SD-WAN service is a model in which networking applications and services are fully outsourced to iTecs, which will provide the software, hardware, networking and transport services required to deliver your traffic. As a turn-key solution for your business, you won't need to worry about the maintenance or configuration of these services and can rely on our experience and expertise to ensure they're running smoothly.

The main benefit of using managed SD-WAN is that it removes the burden from your IT department so they can focus on their day-to-day tasks. Another advantage is that it reduces the cost of maintaining your network infrastructure. By outsourcing this responsibility, you also defer the costs of having to buy additional equipment or hire personnel to manage it.

benefits of using an sd-wan system over a router centric model

The main benefit of SD-WAN is that it eliminates the need for expensive routers and switches. Instead, the technology relies on software running on servers located at each site. These servers act like gateways, routing traffic between different networks. They do this by creating virtual connections between areas.

reduced costs

Companies can reduce overall IT infrastructure expenses by replacing costly routers with a single software-based service.

improved reliability

Compared to traditional router-centric architecture, SD-WAN systems provide superior fault tolerance because there is no single point of failure.

scalability

An SD-WAN can scale up and down depending on demand. If traffic increases during peak hours, additional capacity can be added quickly and easily. When traffic decreases, the same amount of bandwidth can be removed from the network. This flexibility makes it easy to accommodate growth and reduce costs.

security

An SD-Wan can offer greater protection because it separates data traffic from control traffic. Control traffic travels directly between devices, whereas data traffic travels across the public Internet. As a result, data traffic doesn't pass through the corporate firewall, making it less likely to be intercepted and compromised.

sd-wan and larger enterprises

an enterprise office building

In most cases, SD-WAN systems work by connecting local office/branch locations to a central location where the core of the network resides. A single server acts as a gateway, allowing traffic to flow into and out of the data center. Traffic flows through the server, which routes it according to predefined rules.

For example, if a user enters a URL into a web browser, the request goes to the server. If the server determines that the destination address matches a rule, it forwards the request to another server. The second server might forward the request to a third server, etc., until the request reaches the intended destination.

sd-wan is better for cloud environments

One major advantage to SD-WAN is that it is built for the cloud. As more and more business resources and services move to cloud-based solutions, the need for dedicated physical on-site servers becomes obsolete. Additionally, using a router-based architecture introduces latency and impairs performance.

iTecs provides solutions that make sense for the problems faced by businesses today. We understand how important it is to have reliable connectivity, and we know that the only way to achieve this for enterprise businesses with multiple branches is through SD-WAN.
