Quality of experience measurements of multipath TCP applications on iOS mobile devices

Multipath TCP (MPTCP) promises improvements in Quality of Service through connection bundling. This leads to the belief that it will inevitably improve the Quality of Experience (QoE), especially, for mobile applications running on top. The networking and transport layer improvements stem from bundling multiple paths, e.g., WiFi and LTE, as well as increasing the connection reliability through redundancy. For example, a smartphone running an application over WiFi may switch to the cellular network without service interruption upon user movement that gets the device out of the WiFi range, thus avoiding outage events. However, the impact of MPTCP on QoE for different applications has not yet been fully understood.
