functionality can be accessed by any 1P(oneP) application through the flow awareness part of the
presentation layer. The Main Process Packet handling initially populates the CFT entry for a specific
flow. The CFT is also responsible for propagating flow state changes initiated by a 1P application, back
to the host platform’s CFT (if there are changes).
•
The Packet Manager is a shared memory component that provides the infrastructure to allow the DPSS
to move packets between the platform and 1P applications while minimizing the number of copies, etc.
Main Process Packet Processing will initially create the shared buffers for incoming packets. These will
be accessed by various end-developer applications.
DPSS flows
The available flow actions are (in that order):
1
Drop flow
2
Redirected flow
3
Bypass flow
Developing OnePK applications
This procedure guides you to develop onep applications using linux. You will need to use a sample application
to connect to a network device and verify your installation. The sample applications are:
• HelloElement—an application that connects to a network element, obtains the host name, then terminates.
• HelloNetwork—an application that connects to a network, obtains the host name, then terminates.
