We have been using SRX240s at the edge and in metro rings for some time, after teething troubles they have all been solid. I also have some SRX220 using MPLS over GRE over IP connected to the core using xDSL and this also works very well. We use them for LTE/WiMAX/WiFi backhaul.

The only real issue I have is that I would love a SRX240 but with about 4Gb/s of throughput. That would be a nice little product.

Does anybody have any real test results of MPLS throughput on the SRX series?
