[vpp-dev] Multi-threading locks and synchronization

Re: [EXTERNAL] Re: [vpp-dev] Multi-threading locks and synchronization

Thank you for your explanation.  What is recommended way if a custom plugin is working on multiple threads. Direct the packet in the same flow to the same thread or use spinlocks for synchronization. It looks like for IPSEC VPP code is trying the process the packets on the same flow on the same

Re: [EXTERNAL] Re: [vpp-dev] Multi-threading locks and synchronization

Sync is needed. It's a question about the design of packet flow in  VPP. Locks can be avoided if the packets in a flow are processed by the same thread. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group. View/Reply Online (#19757): https://lists.fd.io/g/vpp-dev/message/19
