NetFlow
Generation
Challenges in NetFlow Generation
NetFlow
is a simple, effective way to increase visibility into traffic types and usage
patterns across systems. The flow-generated data can be used to build
relationships and usage patterns between nodes on the network. Routers and
switches that support NetFlow can collect IP traffic statistics to be exported as
NetFlow records. However the processor and memory load of enabling NetFlow can
cause service degradation and affect their ability to pass traffic without
introducing latency and packet drops. Due to this processing overhead, sampled
NetFlow is implemented in most of the high-end routers. Sampling one in every
“n” packets for NetFlow processing can severely limit the visibility needed to
monitor flows and fail to provide a comprehensive network trend analysis.
The
Gigamon Solution
The
advanced capabilities of GigaSMART® technology can be leveraged to
summarize and generate unsampled NetFlow statistics from incoming traffic
streams. Offloading NetFlow Generation to an out-of-band solution like the
Gigamon Visibility Fabric™ completely eliminates the risk of
expending expensive production network resources in generating these analytics.
Combined with the flexibility offered by Gigamon’s patented Flow Mapping®
technology, operators can pick and choose from the incoming flows to generate
NetFlow statistics, without losing critical information. Support for NetFlow
versions 5 and 9 and IP information export (IPFIX), enables seamless
integration with standards-based collectors. NetFlow records can also be
exported to multiple collectors concurrently, providing a single flow source
for business-critical management applications such as security, billing,
capacity planning, and more. Pervasive flow-level visibility across remote
locations and Big Data environments can be used to derive accurate statistics
such as usage patterns, top talkers, and top applications for effective
capacity planning and enforcing security policies.
NetFlow-based
data is summarized information and does not provide access to specific set of
packets or packet payloads. Not having this information can also impede
analysis around latency and jitter, application usage patterns, etc. Gigamon’s
Visibility Fabric architecture is the first in the industry to summarize flow statistics
as well as to provide the flexibility of aggregating, replicating, filtering,
and forwarding raw traffic streams to monitoring tools for detailed
troubleshooting and analytics.
The
Gigamon Visibility Fabric thus establishes a scalable framework to deliver
pervasive flow-level visibility across enterprises, data centers, and service
provider environments to accurately design, engineer, optimize, and manage
their network infrastructure.
