چکيده
This seminar offers a comparative review of three prominent multi-path transport protocols Multipath TCP (MPTCP), Stream Control Transmission Protocol (SCTP), and QUIC in the context of video streaming over heterogeneous network environments. As the demand for high-definition, low-latency video continues to rise, traditional single-path protocols like TCP and UDP face increasing limitations under dynamic conditions such as bandwidth fluctuation, packet loss, and mobility. Multi-path transport protocols have emerged as promising solutions by enabling bandwidth aggregation, failover resilience, and improved load balancing. This review synthesizes findings from existing empirical studies and simulation-based evaluations to critically assess each protocolʹs performance with respect to throughput, latency, packet loss tolerance, and quality of experience (QoE). MPTCP is examined for its bandwidth efficiency in multi-homed scenarios, SCTP for its robustness and failover capabilities, and QUIC for its low-latency attributes and native multiplexing. The seminar highlights the protocolsʹ strengths, limitations, and potential integration with adaptive streaming systems, offering insights into their suitability for future video delivery architectures.
