How votes requests are handled in the network?

[KaramMed]

I've been trying to analyze the packets between the etcd nodes using Wireshark, to see how the candidate sends votes requests, i've seen a couple of http requests like:

• GET /raf/stream/message/<node_id>
• GET /raft/stream/msgapp/<node_id>
• GET /version
• GET /raft/probing
• POST /raft

But none of them seems what I am looking for, does anyone have an idea please how its handled?

Thanks
