Application ID—The application identifier is the unique definition of a
specific Layer 2 to Layer 7 application. Also referred to as protocol-ID.
Application Recognition— Classification of a flow that ends with an
application ID. This can be stateless or stateful. Also called application
Application Session—When a flow is associated with a particular
protocol or application, this is referred to as a session. A session often
implies a user login and logout, and may include the multiple flows of a
BiFlow —A BiFlow is composed of packets associated with both the
forward direction and the reverse direction between endpoints. Also referred to
as a full flow or bi-directional flow. See RFC5101.
Cisco Collection Manager—The Cisco Collection Manager is a set of
software modules that runs on a server. It receives and processes NetFlow
Records. The processed records are stored in the Cisco Collection Manager
database. The database can be either bundled or external.
Cisco Insight v3—Cisco Insight v3 is reporting platform software. It
processes the formatted data from the Collection Manager database. It presents
customized reports, charts, and statistics of the traffic. Cisco Insight v3 is
a Web 2.0 application accessed by using a browser.
—Unidirectional stream of packets between
a given source and destination. Source and destination are each defined by a
network-layer IP address and transport-layer source and destination port
—Modular QoS CLI. A CLI structure that lets
you create traffic polices and attach them to interfaces. A traffic policy
contains a traffic class and one or more QoS features. The QoS features in the
traffic policy determine how the classified traffic is treated.
—Network-Based Application Recognition 2. A
classification engine in Cisco IOS software that recognizes a wide variety of
applications, including web-based applications and client/server applications
that dynamically assign TCP or UDP port numbers. After the application is
recognized, the network can invoke specific services for that application. NBAR
is a key part of the Cisco Content Networking architecture and works with QoS
features to enable you to use network bandwidth efficiently.
—Cisco IOS security and accounting
feature that maintains per-flow information.
—A set of properties that are defined in a
NetFlow sampler map that has been applied to at least one physical interface or
—The definition of a set of properties (such as
the sampling rate) for NetFlow sampling.
—NetFlow export format Version 9. A flexible and
extensible means for carrying NetFlow records from a network node to a
collector. NetFlow Version 9 has definable record types and is self-describing
for easier NetFlow Collection Engine configuration.
—type of service. Second byte in the IP
header that indicates the desired quality of service for a specific datagram.
Transaction—A set of logical exchanges between endpoints. A typical
example of transactions are the series of multiple HTTP GET transactions (each
with a different URL) within the same flow. Typically there is one transaction
within a flow.
UniFlow—A UniFlow is composed of packets sent from a single endpoint to
another single endpoint. Also referred to as a half flow or uni-directional
flow. See RFC5101.
