How would you insert the marker in standard TCP traffic?
The only method I'm aware of is source IP for TCP persistence.
Sorry if I didn't explain clearly, but the very-high-level-algorithm
would be:
-----8<------
empty tcp-persistence hash table (at initialization time)
accept a connection
if (remote IP has persistence entry in the has table)
get persistent backend (already assigned)
else
choose a new backend via roundrobin (care about load?)
Register IP -> backend as a persistent connection
end if
redirect connection to the chosen backend
-----8<------
Everything would be done at tcp/ip level, so no application knowledge
would be needed.
I hope that things are clearer now :)
