To address these challenges, Huawei launches the SD-WAN solution. It uses application-based intelligent traffic steering, intelligent acceleration, and intelligent O&M to deliver an ultimate service experience and provide on-demand interconnection between branches, branches and data centers, and branches and clouds, helping enterprises better cope with service challenges in the cloud era and achieving business success.
Traditionally, IT personnel manually set up devices to go online and provision services. This is time-consuming and requires highly skilled personnel. In addition, the interconnection between branches and the headquarters and among branches becomes increasingly complex. Network orchestration depends on configuration adjustments at multiple sites, which is labor-intensive and prone to errors.
iMaster NCE enables CPEs deployed at branch sites to proactively register and go online once powered on. iMaster NCE-WAN supports plug-and-play through email- and DHCP-based deployment, eliminating the risk of manual errors and reducing service rollout time. In addition, the SD-WAN solution supports on-demand networking, dynamic tunnel establishment, and multiple networking models to flexibly adapt to network adjustment and changes in different service scenarios. Through GUI-based topology orchestration, enterprises implement interconnection between branches and the headquarters and among branches in minutes. A single iMaster NCE-WAN system supports a network with 13,000 or more CPEs.
Manual traffic steering on conventional networks is complex. As a result, customers usually only consider link backup, while sacrificing link resource utilization and key application experience. Let's take standard active/standby link switchover solution as an example. If link quality is poor during videoconferencing, link switchover will not take place unless the link is interrupted. This results in poor video application experience.
To ensure better experience of key enterprise applications, iMaster NCE-WAN provides hybrid link access capabilities, identifies predefined and user-defined applications, and supports application-based intelligent traffic steering. This means that high-quality services are transmitted over private lines, while low-quality services go over Internet lines. In addition, iMaster NCE-WAN supports link quality detection and implements intelligent traffic steering based on latency, jitter, packet loss rate, and bandwidth usage. If the customer network is faulty or the link quality is unstable, link switchover is flexible, ensuring the service experience of key applications and retaining customers.
Typically, administrators implement O&M and monitoring of carriers' network quality and device status one-by-one at each site or device. This requires highly skilled O&M personnel and makes it difficult to restore services after faults occur.
iMaster NCE-WAN displays the site and link status on the GIS map. Customers quickly learn the service layout, obtain the health status of sites on the live network, and identify faulty sites and links. iMaster NCE-WAN also displays the quality trend (latency, packet loss, jitter, and throughput) based on specified links and applications and quickly demarcates and locates faults. As such, customers can quickly restore services, improve O&M efficiency, and reduce O&M costs.
