Yes, I realize that, it could be work. Thanks to hongjun. But vl_api_rpc_call_main_thread will degrade packet handling performance in worker thread, I don't know if there is a common and high performance way to do this? And also I guess vlib_process_signal_event can only be used in main thre

Hi Hui, I think the SNAT example maybe meet what you want: snat_in2out_node_fn_inline: (in worker thread) slow_path snat_ipfix_logging_nat44_ses_create vl_api_rpc_call_main_thread Regards, Hongjun From: wang.hu...@zte.com.cn [mailto:wang.hu...@zte.com.cn] Sent: Wednesda

Maybe if you could expand on what it is you are trying to achieve? //when starting worker thread , the main thread can't receive packet from IO, so we want to transfer some packet to main thread to continue processing. Is it specifically to do with DHCP (and proxy) or is that just the code y

hi Dave and hongjun: We also got confused with below code. Dos it works correctly? Maybe the dhcp_proxy_to_client_input fuction runs in the worker thread, and it will call vlib_process_signal_event function to trigger dhcp-proccess node in the main thread. If it works, maybe the questio

Re: [vpp-dev] issues when enable proxy-arp

Hi, Neale Thanks for help. In VPP16.06, there is no command like “sh adj” and “sh adj nbr N”, so I use VPP17.01 to get the two outputs. And after my first ping from cont2(192.168.1.2) to cont1(192.168.1.1), no packet was received by cont1. And vpp will restart. Below is the result: # vppctl sh

hi all: Incidentally, we have also another question. Is there a common and high-performance way to deliver some control-plane packets from worker thread to the main thread? We found vl_api_rpc_call_main_thread can handle it, and it is already used in BFD bfd_rpc_update_session. But there is

Hi Keith and Dave, Thank you for your detailed advice. We will take your suggestions into consideration carefully. By the way, It is not used for NSH_SFC. It is VPP specifics. Thanks a lot, Hongjun At 2017-03-08 06:21:20, "Keith Burns" wrote: Hongjun, We replicate the graph across

Re: [vpp-dev] Signal events between graph nodes within different threads

Hongjun, We replicate the graph across all threads. The question is what do you want the node to do when it sees this event? If for instance a packet triggered an event that another node needs to know about in order to subsequently process THAT packet, ignoring the fact it's going to stay

Hi Pavel, Both DPOs and Feature arcs are both higher layer abstractions to construct the VLIB node graph. DPOs are an abstract concept, a base class if you like, for objects that represent the actions that should be performed on the packet as it is switched. As you know, an object is both data
