To monitor the traffic utilization of Layer 7 applications, we need to enable Network Based Application Recognition (NBAR) on the WAN interfaces of the edge devices. How do you identify the Layer 7 application traffic utilization?

The rules placed on the firewall would become outdated within a short span of time. Furthermore, the IP addresses and port numbers used by cloud-based applications and storage solutions are dynamic. Non-business apps, like social media and video streaming apps, intermittently utilize much of the available bandwidth in the corporate network, which negatively impacts the performance of business-critical apps and the network.ĭropping traffic from non-business Layer 7 applications, random ports, and social media by identifying all the IP addresses and placing access control lists on the firewall would be tedious and wouldn’t scale for enterprise networks. Network administrators always think about 100% uptime and having a high-performance network. These cloud applications are represented as Layer 7 applications or services. Traditional flow-based traffic analysis is used to identify Layer 3 application traffic based on the port and protocol, with respect to the standards of the Internet Assigned Numbers Authority.īut today, a lot of applications and services are cloud-based, and cloud adoption is growing rapidly. Over the last two decades, administrators have used traditional NetFlow and other similar flow technologies to identify the types of traffic in their networks. Therefore, administrators should have the necessary controls to prioritize business applications on WAN links. Non-critical apps, like social media apps, downgrade the performance of WAN links.

They want their critical business applications over the WAN to perform at their best. Network administrators around the globe are very concerned about the types of traffic in their networks.
