Systems and methods for controlling Quality-of-Service (“QoS”) in a Virtual Private Network (“VPN”) in a transport network providing a plurality of QoS bearers. The methods involve: establishing, between two VPN endpoints, a plurality of VPN tunnels through the transport network, including at least a default VPN tunnel associated with a first QoS bearer and an alternate VPN tunnel associated with a second QoS bearer; receiving and analyzing a data block; applying a VPN policy to assign the data block to either default VPN tunnel or alternate VPN tunnel; and encapsulating the data block in a transport data block including at least one indicator. The indicator specifies whether the transport data block is to be communicated by the transport network using the first QoS bearer or second QoS bearer.
