How Cisco IT Uses NetFlow to Capture Network Behavior, Security, and Capacity Data

Tags:
switching

Overview Not surprisingly, the ability to characterize IP traffic and account for how and where it flows is critical. Monitoring IP traffic flow facilitates more accurate capacity planning. It ensures that resources are used appropriately. It helps IT determine where to apply Quality of Service (QoS) so that vital traffic receives priority. And it plays a vital role in network security. Cisco relied almost exclusively on Simple Network Protocol (SNMP) to monitor Internet bandwidth. Gradually, Cisco has deployed Cisco IOS NetFlow technology, which is built into most Cisco switches and routers. NetFlow answers the who, what, when, where, and how of network traffic, and it has become the primary network accounting technology and anomaly-detection technology in the industry.

ISPs drawn into illegal file sharing blame game

No one is arguing that it is illegal for an ISP to buy bigger Cisco routers to deal with increased P2P traffic," he said. Joltid said its traffic on FastTrack protocols can account for nearly 70 per cent of the network's total bandwidth.

RFID rollouts: Are you about to cripple your network?

Scalability is a function of network architecture, not simply a matter of adding routers and switches, and it must be planned," the report says. Network security should also be addressed as a priority, the whitepaper recommends.

How closely are you monitoring?

If you're just monitoring what's going on in the network then you could just go ahead and get the flow data. Plug an SNMP (simple network management protocol) or RMON (remote monitoring) agent into a node on the network to get an idea of what it's...

Quocirca's Straight Talking: Out-of-the-box options

Switches that control the traffic on local area networks (LANs) and routers that connect LANs to each other forming wide area networks (WANs) have been around for years. However, unlike switches, routers and firewalls, not all of this technology...
