When it comes to analyzing network traffic for tasks like peering, capacity planning, and DDoS attack detection, there are multiple auxiliary sources that can be utilized to supplement flow information. IPv6 peerings are starting to outgrow a single node. It also allowed mirroring the setup for our IPv6 fabric.

We really respected their thoroughness and the fact that they are practicing network engineers, so as we’ve come up with cool new gizmos in our product, we’ve asked them to extend their review. Following here, from their latest review, are some excerpts that focus on Kentik NPM, our enhanced network performance monitoring solution.
It’s also just one of the many interesting statistics that we run across as we operate our SaaS platform for network traffic analytics. Network Devices: Which Brands are Trending? Cisco Systems is by far the market leader in the overall IT Networking sector. Google maintains Internet-wide stats on the overall IPv6 adoption rate.
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. J-Flow : J-Flow is a flow monitoring implementation from Juniper Networks. What if you don’t have any network devices that can export flow?
IPv6 is another major addition to the platform, reflecting the next generation of networking. You’re able to set a master node with child nodes to see how they interact, and you’re able to configure container networking between different servers, to name a few examples. Upgraded interface and server logs.
How flow protocols adapt as network needs evolve. Network flow records today are an integral part of the network operations landscape. What about capturing MAC address, or VLAN tag, or IPv6? IPv6, MAC addresses, VLAN, and MPLS) makes it more limited than other alternatives.
No matter how well your network is routing IP traffic, the network is essentially down without DNS to resolve hostnames like www.google.com to their underlying IP addresses. As with any critical component, network operations needs to be able to continuously monitor DNS performance and to respond quickly to any issues that may arise.
Also, to cut down on CPU and network bandwidth, flows are usually only “exported” on average every 10 seconds to a few minutes. sFlow, on the other hand, is based on interface counters and flow samples created by the network management software of each router or switch. This can result in very bursty traffic on sub-minute time scales.
Record types : It’s useful to know, for example, that a record type is an A record vs an AAAA record because the reason one user can see the content and another can’t see it might have everything to do with the fact that they aren’t able to connect to IPv6 from their house, while another user can.
