NimbostratusSMPP TCP Splitting
Can F5 do TCP splitting for SMPP service by iRule?? I mean, in SMPP serivce, one TCP session will include multiple "sessions", and F5 can distribute those "sessions" to different servers in one pool??...

CirrusYes, it's possible, but you will need to build an SMPP message parser. Basically, the idea is to issue LB::detach command after the end of each message transmission - which will force a new load-balancing decision to a different server in the pool for the subsequent message. The rough pseudocode idea is something like this:
when CLIENT_ACCEPTED {
TCP::collect
}
when CLIENT_DATA {
determine that beginning and end of the message was received
if end of the message was received {
LB::detach
}
TCP::release
TCP::collect
}
