Not Just for NetFlow, Kentik Detect’s Analytics Cover All Major Flow Protocols. In networking terms, a “flow” defines a uni-directional set of packets sharing common attributes such as source and destination IP, source and destination ports, IP protocol, and type of service. Flow Data Variations. Source & dest port.

This table is populated automatically when a switch receives a frame on a port. As a frame is received on a port, its source MAC address is noted. The switch receives the frame from PC-1 that contains the MAC address 80::01 on port 1. Port 1 is configured as a member of VLAN-11. Then PC-1 wants to communicate with PC-2.

This includes port, IP source, destination, port numbers, and other markings such as quality of service (QoS). You need both sets of data to make intelligent decisions and optimize the entire network.

At Network Kings, you will learn networking concepts (routing, switching, IP addressing) and basic network security fundamentalssuch as how to block websites and manage port numbers. Understanding the OSI model and routing protocols is crucial; because routing is the backbone of internet connectivity.

Send these pings using the Internet Control Message Protocol (ICMP) or TCP to one or any of the devices you believe to be involved. In some cases if ICMP is filtered, you can usually switch to TCP (Transmission Control Protocol) and use tcping, telnet, or another TCP-based method to check for reachability. Get the Path with Traceroute.

This configuration is known as a “split-tunnel” configuration and is set up by rules to exclude specific ports, protocols, or networks. This data is useful for Kentik’s automated capacity planning workflows and building topological maps (layer 2 and layer 3 connectivity). More advanced VPNs can do this by application type.

Unlike dynamic routes, learned through dynamic routing protocols such as OSPF (Open Shortest Path First) or EIGRP (Enhanced Interior Gateway Routing Protocol), static routes require the network administrator to specify the next hop or destination IP address.
