Network Coding-Based Congestion Control at Network Layer: Protocol Design and Evaluation

The paper proposes a congestion control protocol based on Network Coding (NC) operations for the butterfly topology. The proposed protocol defines XOR-based coding and decoding algorithms adapted to streams having different rates and characteristics, as well as a signalling protocol required for dynamic activation and deactivation of NC operations. Some general principles related to the integration of NC operations into data transmission protocols are also discussed. The congestion control protocol proposed was simulated in OMNeT++ and implemented in a real network to demonstrate its feasibility and to test the functioning of the proposed coding and signalling algorithm in different scenarios.
