Simulating multiple low bandwidth network interfaces on Linux

I\'m making a testbed for a Linux based application that uses multiple GPRS connections and aggregates their bandwidth.

I'm making a testbed for a Linux based application that uses multiple GPRS connections and aggregates their bandwidth.

I'd like to test this application on my local ethernet by emulating low bandwidth开发者_StackOverflow中文版 high latency network conditions on multiple network interfaces.

To achieve this, I tried setting up multiple Virtual NICs using macvlans on single ethernet and then I tried traffic shaping using wondershaper and netem on each interface. However, for some reason, traffic is not being shaped on Macvlans.

Could there be a better solution for emulating multiple cellular interfaces using single ethernet card?
