Hi VPP-Experts, We need to classify the packets in our custom plugins in synchronous to some other functionality. To achieve this: we are planning to use following approach. Can you let us know, if this approach works fine without any unforeseen road blocks at some point.
1. Use the existing vnet classify infrastructure for maintaining the classify sessions and tables. But , do not apply these tables to any interfaces as acls. Store the classify table and session indexes in the custom plugin. 2. In our custom plugin, use the above classify tables to match the packet using following functions of acl plugin acl_fill_5tuple acl_plugin_match_5tuple_inline 3. Get the results from the above function to check if any table/session matched for this packet, and take action in the custom plugin. The main reason for this approach is that we want the classification to applied after our custom plugin and also in a syncrhronous way within our graph node. We can not afford to send the packet for classification to another node like ip4_classify. If the approach has any issues, are there any set of apis available, to achieve classification from any custom plugin. Please let us know. -- Thanks & Regards, Murthy
