Prepared for 3GPP ATSSS and Hybrid Access

MP-DCCP is designed as protocol for multipath transport of services with no strict demand on reliability and in-order delivery and therefore fits ideally into the scope of above use cases. UDP or IP is the layer where it can reside as described with the MP-DCCP framework. As dedicated solution it's lighweight and scalable and does not make any compromise when it comes to Steering (Access selection), Switching (Seamless handover) and Splitting (Aggregation). In combination with U-DCCP it works over any Internet access with UDP capable middle-boxes.

Native support of DCCP applications

Without modification, any DCCP application can use MP-DCCP in an automated fashion or by manual selection. The multipath extension for DCCP integrates therefore transparently into the DCCP communication. By the nature of (MP-)DCCP, it qualifies for real time video and audio communication and provides much better experience due to inherent multipath capabilities - Reliability, Resilience and Throughput Aggregation.

Open Source

Available as Open Source software enhancing the Linux network stack. Free to be used in commercial environments and open for contribution.

Full Modularized Scheduling and Resequencing

Traffic scheduling, the decision how to distribute traffic across multiple paths, as well as converging this traffic (reorder) on receiver side, can follow different logics. MP-DCCP provides for both, the scheduling and re-ordering, a modular engine which allows to load different logics under operation. With that it's flexible to adjust the distribution metrics and the degree of re-ordering on a demand basis.

Real prototypes

Prototype implementation within Hybrid CPEs and Android smartphones such as Google Pixel devices have already proven usability, based on the Linux reference implementation.


In a collaborative approach, the MP-DCCP was initiated by Deutsche Telekom and further developed with Karlstad University, City, University London and BT. In the meanwhile simulation environments and multiple testbeds exist across the globe. This helps to investigate, verify and optimize MP-DCCP, with all its interpendencies under realistic conditions, towards a powerful tool for multipath transport. This collaboration is open to be joined...
