Explanation:
Explanation
next-generation NetEngine AR routers are intelligent edge routers that provide comprehensive services for enterprises, such as WAN access, SD-WAN, VPN, voice, video, security, cloud interconnection, and IoT .
They have several strengths that differentiate them from other products in the market, such as:
Incorporating an industry-leading CPU+NP architecture, providing industry-leading L3 to L7 full-service efficient processing. The CPU+NP architecture combines the advantages of both CPU-based general-purpose processing and NP-based hardware acceleration, enabling high-performance processing of various services at different layers .
Incorporating iPath (application-based intelligent traffic steering & optimization) and A-FEC {no frame freezing or artifacts even at a 20% packet loss rate). iPath is a technology that intelligently steers traffic based on application types, quality requirements, link conditions, and policies, optimizing the user experience and resource utilization . A-FEC is a technology that enhances the error correction capability of video streams, ensuring smooth video transmission even under high packet loss scenarios .
Offering three times the industry average performance based on x86. The next-generation NetEngine AR routers use x86 processors that deliver high computing power and scalability, enabling them to support more services and users with lower power consumption .
Featuring multi-mode ZTP on-demand network orchestration; real-time fault alarms and 45+ visualized reports. The next-generation NetEngine AR routers support zero-touch provisioning (ZTP), which simplifies the network deployment and management process by automatically discovering, registering, configuring, and upgrading devices . They also support real-time fault alarms and 45+ visualized reports that provide comprehensive network monitoring and analysis capabilities .
