Hi Alfredo, Thanks for your post. Let me check how the zbalance_ipc is using PF RING libraries. Could you please let me know what sort of IPC is used by zbalance? Is it a FIFO or Pipes. Also, if I use my own application for implementing packet classifier can I use more own IPC like socket or message queue? Does PF RING provides all the libraries?

Please consider using PF_RING ZC, it works with any adapter and standard drivers, and you can write your packet classifier in userspace (see examples_zc/zbalance_ipc) which is much more straightforward.

Basically I want to implement a packet classifier at PF-Ring Level and classify packet based on Protocol Type whether its is a UDP or TCP service and route it to specific application. Now, although I could classify the packet at classifier I am not able to identify on how I should route to the specific application. Because in user space its quite straight forward where I can route based on the port of the application that is running. I’ll just try to find the send or SendTo and directly call for each packet type. Here since I am bit new to kernel space, I am trying to find a place holder in PF Ring Code where I can find the sending point after classifying. Can I mention certain port numbers at PF Ring level for the application?. Or do I need to create a ring buffer for specific application?. Can you please help? . Basically I want to know the place holder to send a specific packet in PF ring after classifying it. <image003.jpg> Regards VENKATA VELDANDA L&T Technology Services Ltd www.LntTechservices.com<http://www.lnttechservices.com/> This Email may contain confidential or privileged information for the intended recipient (s).
