Many of today's mobile devices are equipped with multiple network interfaces that can be used to connect to the Internet, including Ethernet, WiFi, 3G, and Bluetooth. However, current operating systems, such as Windows and Linux, typically choose only one of the available network interfaces and assign all the traffic to it, even if more than one is connected to the Internet. This results in an obvious under utilization of the available bandwidth. Different bandwidth aggregation techniques suggested altering different layers of the TCP/IP stack which requires applying modifications on the client's stack and/or the cloud, which cannot be widely deployed easily.
