This MIB module defines managed objects that facilitate the
management of AON node.
The information available through this MIB includes
o AON node state i.e., whether the AON node is 'unregistered',
'registered', 'active', 'inactive'.
o Node metrics information when a node is in the 'active'
o The node metrics information includes the number of messages
received by the node, number of PEPs deployed and number of
messages received by a PEP as well as information about the end
points that the messages are delivered to. The metrics are
reset when the AON data plane is restarted.
The following terms are used throughout this MIB:
AON : Application Oriented Networking.

Figure 1 : AON
AON data plane: This is the piece of software that runs on the
AON node and is responsible for processing application message
AMC : AON Management Console. A Web-based application used to
manage the AON installation, upgrade, and operation. This is
also referred to as the AON Management Plane.
AMA : AON Management Agent. An agent that runs on the AON node
and acts as intermediary between the AON data plane and the
AON Node : An AON node is either a single device (blade or
appliance) or a virtual cluster of devices (blades or
appliances) that are running the AON software.
AON Cloud : A group of AON nodes that are connected together
via NextHop configuration is referred to as an AON cloud.

Figure 2: AON Cloud
Entry Node : The first node in an AON cloud, generally the one
closest to the client, is known as the Entry Node. This node
is also sometimes referred to as the Client Proxy.
Exit Node : The ultimate node in an AON cloud, generally the
one closest to the server, is known as the Exit Node. This
node is also sometimes referred to as the Server Proxy.
Intermediate Node : Any AON node in an AON cloud that is
neither directly communicating with the client or the server
(i.e. neither an Entry Node nor an Exit Node) is known as an
PEP : Policy Execution Plan. A PEP is a sequence of bladelets
that determine how a message is processed in AON.
MEP : Message Exchange Pattern. MEP describes the pattern of
messages required by a communications protocol to establish or
use a communication channel. There are two major message
exchange patterns: a request response pattern, and a one way
Bladelet : A bladelet is a piece of software that performs a
specific message handling function. Bladelets are combined
together into PEPs.
Send Bladelet : Routing bladelet that sends a message to a
Notify Bladelet : Bladelet for generating a custom
notification (either as SNMP trap or email) based on user
NamedException : A NamedException is exposed by a bladelet as
connection points to identify a recoverable exception. The
action to handle a NamedException thrown by a bladelet can be
explicitly designed in the PEP by associating a execution path
which comprises of a series of bladelet.
Exception Block : It is the block in the PEP that is marked by
the exception marker and which is executed in case of a
bladelet exception that is not a NamedException that has an
output path associated with it.
URI : Uniform Resource Identifier. A URI (Uniform Resource
Identifier) is the way you identify any content in the Internet
space, whether it be a page of text, a video or sound clip, a
still or animated image, or a program.
The most common form of URI is the Web page address, which is a
particular form or subset of URI called a Uniform Resource
Locator (URL). A URI typically describes:
* mechanism used to access the resource
* specific computer that the resource is housed in
* specific name of the resource (a file name) on the computer.
URL : Uniform Resource Locator. A URL (Uniform Resource
Locator) is the unique Internet address for a file. The URL
contains the name of the protocol to be used to access the file
resource, a domain name that identifies a specific computer on
the Internet, and a pathname, a hierarchical description that
specifies the location of a file in that computer.
End point: An end point is an application that is either a
sender (client) or a receiver (server) of messages that
communicates with AON.
