The overwhelming data and the instant requirement to retrieve specific information drives modern businesses. With offices moving to the cloud, storing and retrieving data has become simple. Due to their cloud-friendly feature, traditional home routers are being replaced by SD-WAN routers. To know why people are moving away from home routers to virtual WAN architecture, we need to first understand the functions of both routers.

Home routers are the most common network device that connects your local home network with the internet. There are both wired and wireless home routers that facilitate connecting of multiple devices to the internet. Traditional routers facilitate the distribution of control functions across the device in a network. It routes traffic based on the TCP/IP address, ACL, basic firewall and limited QoS features. Home routers are not cloud and enterprise-friendly. They usually are a low specification router hardware and complex to configure and fix, resulting in poor user experience (such as router hang or poor network performance) and regular downtimes.

SD-WAN routers are cloud-friendly and provide superior Quality of Experience (QoEx) for the users. You can set QoS and security policy enforcement depending on your business needs. Enterprises are moving to Software-as-a-Service (SaaS), where businesses access applications on the cloud, not from a server(s) deployed in the data centre. Virtual WAN architecture facilitates a combination of communication services like MPLS, LTE and broadband to connect users to applications securely. SD-WAN routers are designed to support applications hosted on-premises, public or private clouds, data centres and SaaS services with the highest performance levels.

Difference between a generic router and an SD-WAN router

Limited memory configuration: Home routers have a limited CPU and memory configuration, which can lead to limited QoS and Firewall performance resulting in packet loss or router freeze. On the contrary, in SD-WAN routers, there is more than adequate CPU and memory configuration, which can provide superior overall device performance. Thus, minimizing or eliminating packet loss and device freeze.

Limited lifespan: Traditional routers are made of a plastic body that does not sustain heat dissipation, thereby reducing the router's overall performance. As a result, the router freezes or reboots frequently. In the case of SD-WAN, the router is made of metal and can withstand operating temperature effectively. Therefore, no reboots or freezes in the network, ensuring a longer life for the router.

Aggregation of connectivity: Downtime is frequent with home routers as it comes with one WAN port and no LTE or 4G option. While an SD-WAN router has multiple WAN ports along with LTE/4G options, ensuring your connectivity is up and running all the time with features such as aggregation and failover.

IoT friendly: The Internet of things (IoT) connects internet-enabled
devices to cloud-based applications to transmit information outward and inward.

Home routers are not IoT-friendly since they often lack basic features and, in some cases, hardware support too. SD-WAN routers monitor the network for IoT applications to scale, secure and optimize bandwidth utilization. Mission-critical IoT applications are supported efficiently by Edge SD-WAN architecture to optimize and secure applications. Enterprises can improve operations by installing IoT applications at the network edge for optimum data transmission on wired, wireless, 4G or 5G infrastructure.
