Network elements that support traffic monitoring protocols such as NetFlow and sFlow extract critical details from packet flows, like source, destination, byte and packet counts, and other attributes. NetFlow is the trade name known for a session sampling flow protocol invented by Cisco Systems that is widely used in the networking industry.

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. What is a Static Route? What are the disadvantages of dynamic routing?

The usual culprits include ransomware, malware, ill-considered BYOD (Bring Your Own Device) strategies, and vulnerable protocols. With small branch offices often lax in their security policies, they become a favorite entry port for all too many attackers. However, data replication is subjected to higher usage of network bandwidth.

Sometimes, your connections don’t have enough bandwidth. Send these pings using the Internet Control Message Protocol (ICMP) or TCP to one or any of the devices you believe to be involved. Both packets and flows provide information about the source and destination IPs, ports, and protocols. Packets simply get dropped.

The most common form of DDoS is the volumetric attack, in which the intent is to congest all of the target network’s bandwidth. So next we’ll look at the protocol and destination port # of the traffic. In all cases, a clear assessment is important to understand the best way to mitigate the attack. Assessing mitigation options.

Comparing flow protocols for real-world large-scale networks. A lot of ink has been spilled over the years on the topic of flow protocols, specifically how they work and their relative accuracy. Historically, however, most of the testing, opinion, and coverage has been based on enterprise use cases and fairly low-bandwidth assumptions.

Some have heard that only egress traffic is chargeable, or that inter-region/VPC bandwidth is more expensive than intra-region/VPC traffic, and that traffic consumption may be charged differently for each geo / zone.

The CDN and the ISP peers over an IXP, the volume drives port upgrades, and private connections are impossible. Removing traffic from the edge will save money on transit and IXP port fees and lower the risk of congestion. The first two scenarios are straightforward.
