Multipath communication has gained increasing interest in recent years: Using multiple interfaces offers both better Quality of Service and Quality of Experience. Use-cases are smartphones which are equipped with at least two network interfaces (WLAN and cellular) or boosting low data rate DSL lines by adding cellular or even satellite links. As an example, Multipath TCP (RFC 8684) is a well-studied multipath protocol available in the Linux Kernel. This seminar discusses basic principles of multipath communication and state of the art research papers.

Following is a first set of possible topics and papers – the final setup may change depending on the number of participants.
