Subject: Re: [dpdk-users] [dpdk-dev] Fwd: Sharing tables among pipelines

Something I have gathered reading through code if it helps, ip_pipeline is 
designed such that user side cli (_fe) runs in master pipeline and sends conf 
requests to various other packet processing pipelines (_be) which handle such 
requests at intervals. These can run on same or different threads(cores) as per 
conf, no locking requirement as table-updation & table-reading (packet 
processing) always happens in same pipeline so always same thread. Master 
pipeline can be configured to run on a separate core & it should be the case, 
but table updation happens in pipeline thread only at lower priority.

Hi all,

Thanks for your reply.

As given in the link(3rd point), what I need is single writer
thread(pipeline) performing table entry add/delete operations and another
thread(which is in turn another pipeline) that performs lookup operations
to the same table entries.


Thanks,
Nidhia Varghese
