Is MPTCP supported?

I have no idea if MPTCP on its own is supported by the F5 (no hits in devcentral nor the supportpages) but if you have a MPTCP device in front of it then the flows are just regular TCP-sessions.

 

 

However reading a description of MPTCP:

 

 

"

 

MultiPath TCP (MPTCP) is an effort towards enabling the simultaneous use of several IP-addresses/interfaces by a modification of TCP that presents a regular TCP interface to applications, while in fact spreading data across several subflows. Benefits of this include better resource utilization, better throughput and smoother reaction to failures.

it sounds somwhat like regular setup of F5.

 

 

When you setup a VSERVER in F5 this VSERVER will DNAT the traffic towards a pool of members. The loadbalancing algorithm can be for example roundrobin.

 

 

If you do this for a pool of webservers you can spread the load while each flow will go to a dedicated server. For example if a client requests 9 pictures and you have 3 members in your pool (and use roundrobin as algo) - the result will be that server1 gets request 1,4,7, server2 gets request 2,5,8 and server3 gets request 3,6,9.
