FREMONT, CA: Today, companies face a revolution focused on networking technologies that maximize network optimization and are capable of integrating cloud and multi-cloud with Core Network Architecture.
The WAN optimization is supported by SD-WAN solutions that enable the use of WAN access resources and help businesses use bandwidth more effectively, enhancing the overall performance without compromising security for critical applications.
Edge devices are a crucial element of SDN/SD-WAN solutions as they also provide security and WAN optimization features in addition to integrating the characteristics of a branch or office router.
Features desired in an SD-WAN Edge router
1. LAN and WAN -level flexibility
The large offices might suggest providing WAN, Wi-Fi, switch and other functions on separate devices, but the SD-WAN Edge router incorporating an integrated switch, Wi-Fi/WLAN, VLAN, and others would provide a very high cost-performance ratio for SMEs on the same device.
Several WAN access, like SFP Fiber, ADSL2+/VDSL, Ethernet WAN, and access to 4G/LTE/5G cellular networks, must be available SD-WAN Edge router.
2. Bandwidth
The SD-WAN Edge router must be prepared to use its WAN's versatility to offer a bandwidth based on the requirements of every architecture, with the various WAN types described above.
While more utilities, software, and other applications migrate to the cloud, businesses of all sizes will need a substantial amount of bandwidth and the largest businesses will be rewarded for providing a wide throughput. The SD-WAN Edge router integrates switching or Wi-Fi features, the big businesses can enjoy the bandwidth and throughput even more. Therefore, an SD-WAN Edge router based on X86 technology may be a very appealing choice for a big company.
3. Security
Security is becoming increasingly necessary. Even though security has always been essential, when it comes to cloud and multi-cloud management, the importance of ensuring the security of a company's or organization's network increases dramatically. As a result, the SD-WAN Edge router's ability to integrate VPNs, IPsec, firewalls, access lists, and other security features is critical.
