StreamGroomers oversee and manage the flow of traffic within Wide Area Networks (WAN). They function seamlessly, regardless of the specific network framework, positioned between the LAN and WAN access router, with control facilitated through an out-of-band management setup. To guarantee uninterrupted service, they employ high-availability architectures. StreamGroomers conduct real-time analysis of network traffic at wire speed, gathering extensive measurements and packet data from various points throughout the network. From this information, indicators are generated in real-time to reflect the current state of network performance. The collected data is then consolidated and transmitted to a central repository with minimal impact on network resources, allowing for rapid analysis and troubleshooting, while also maintaining thorough records for forensic purposes. Additionally, the Deep Packet Inspection feature of the StreamGroomer examines Layer 2-7 packet data to accurately identify applications and user sessions based on a predefined catalog of over 400 services, thus enhancing network visibility and control. This capability not only aids in performance monitoring but also supports proactive network management strategies.
