 Operation
 ---------
 
-The ``librte_pdump`` library works on a client/server model. The server is responsible for enabling or
-disabling the packet capture and the clients are responsible for requesting the enabling or disabling of
-the packet capture.
-
-The packet capture framework, as part of its initialization, creates the pthread and the server socket in
-the pthread. The application that calls the framework initialization will have the server socket created,
-either under the path that the application has passed or under the default path i.e. either ``/var/run/.dpdk`` for
-root user or ``~/.dpdk`` for non root user.
-
-Applications that request enabling or disabling of the packet capture will have the client socket created either under
-the path that the application has passed or under the default path i.e. either ``/var/run/.dpdk`` for root user or
-``~/.dpdk`` for not root user to send the requests to the server. The server socket will listen for client requests for
-enabling or disabling the packet capture.

+The primary process using ``librte_pdump`` is responsible for initializing the packet
+capture framework. The packet capture framework, as part of its initialization, creates the
+multi process channel to facilitate communication with secondary process, so the
+secondary process ``app/pdump`` tool is responsible for enabling and disabling the packet capture on ports.
 
 Implementation Details
 ----------------------
 
-The library API ``rte_pdump_init()``, initializes the packet capture framework by creating the pdump server by calling
-``rte_mp_action_register()`` function. The server will listen to the client requests to enable or disable the
-packet capture.
+The library API ``rte_pdump_init()``, initializes the packet capture framework by creating the multi process
+channel using ``rte_mp_action_register()`` API. The primary process will listen to secondary process requests
+to enable or disable the packet capture over the multi process channel.
 
 The library APIs ``rte_pdump_enable()`` and ``rte_pdump_enable_by_deviceid()`` enables the packet capture.
-On each call to these APIs, the library creates a separate client socket, creates the "pdump enable" request and sends
-the request to the server. The server that is listening on the socket will take the request and enable the packet capture
-by registering the Ethernet RX and TX callbacks for the given port or device_id and queue combinations.
-Then the server will mirror the packets to the new mempool and enqueue them to the rte_ring that clients have passed
-to these APIs. The server also sends the response back to the client about the status of the request that was processed.
-After the response is received from the server, the client socket is closed.
+For the calls to these APIs from secondary process, the library creates the "pdump enable" request and sends
+the request to the primary process over the multi process channel. The primary process takes this request
+and enables the packet capture by registering the Ethernet RX and TX callbacks for the given port or device_id
+and queue combinations. Then the primary process will mirror the packets to the new mempool and enqueue them to
+the rte_ring that secondary process have passed to these APIs.
 
 The library APIs ``rte_pdump_disable()`` and ``rte_pdump_disable_by_deviceid()`` disables the packet capture.
-On each call to these APIs, the library creates a separate client socket, creates the "pdump disable" request and sends
-the request to the server. The server that is listening on the socket will take the request and disable the packet
-capture by removing the Ethernet RX and TX callbacks for the given port or device_id and queue combinations. The server
-also sends the response back to the client about the status of the request that was processed. After the response is
-received from the server, the client socket is closed.

+the request to the primary process over the multi process channel. The primary process takes this request and disables the packet capture by removing the Ethernet RX and TX callbacks for the given port or device_id and queue combinations.
 
 The library API ``rte_pdump_uninit()``, uninitializes the packet capture framework by calling ``rte_mp_action_unregister()``
 function.
