NOSE - Niagara OS

In today’s networks, security, monitoring, application and performance appliances are instrumental for smooth operation, meeting state and federal regulations and securing integrity of the network and users. People often tend to neglect the monitoring infrastructure and the importance of these appliances and tools. As traffic passes the network, these tools require access to specific traffic, application or flow. Therefore, management and optimization of tools are instrumental for well-functioning, secured networks. 

Niagara Networks’ Network Operating Software Edition (NOSE) provides the intelligence required for improving performance, monitoring and security of networks. As the enabler of multiple applications, the NOSE can groom, trim, optimize and manipulate any packet that is sent from the production network to Niagara Networks’ distributed architecture.

Network operations and security teams can share access to end-to-end visibility provided by NOSE.  Additionally, access to any element of the Niagara Network is achieved through the NVC platform, running an Openflow interface.
