No, no real load balancing. Since I use src-IP for classifier in the PCC it basically means router groups connections by their source IP. Meaning a connection, even multiple, made by one srce-IP all get same PCC result and thus same GW. It is even so that same IP always get same PCC result, so always same GW.
The load balancing can only be done in respect of many users with different IP's. The more users, the better the average balancing of their speeds is achieved.
But basically by using src-IP classifier only you might as well put each client IP in a manual mangle rule and spread them over your WAN's.
So, the advantage of this type of PCC is no broken links and an automated client IP spread over the available gateway's.
Disadvantage is that per client no load balance is achieved and it is hard to see which client is actually getting what result (and thus which GW). For troubleshooting upon client complaints it is sometimes need to know what GW his IP is using. If same router is also performing src-nat into the WAN IP's it becomes hard to find out...
It is possible with PCC to arrange better load-balancing, but then you have to start using srce-IP+Port as classifier and even dst-IP+Port.
The problem now is that many authentication sessions, like bank log in, web-mail, don't work anymore.
Up to 2 years ago I worked with a 7-WAN load balancing from Peplink (http://www.peplink.com
) which did do a better job in load balancing for a single machine (it is a dedicated multiple WAN load balancing with many configurable options) but also with this device it was impossible to create a system that would 100% eliminate the ´broken-link´ issue. Some sites have such high security settings that it needs to have all user request to come from one and the same IP, even if the pages are send to the client from different servers.
My clients are all assigned less speed then the capacity of each WAN connection I have so there is no real need to have their traffic spread over many WAN connections to get higher speeds.
But if you really are looking for a solution to use the combined download capacity from several WAN connections into one machine (or any machine on your LAN) then a peplink is definitely a good purchase. The GUI is much more simple the ROS and they have a good help desk.
