Compatibility of Heterogeneous Devices Based on 2.5GBase-T

This paper proposes a technology that provides automatic link options for mutual compatibility among devices from different chip vendors. Many different vendors manufacture chips, which often require interconnections with existing Internet services, and the different data transmission environments limit the connectivity between devices. Consequently, the Internet quality of service drops below the standard expected by subscribers. The proposed technology secures a compatibility between devices related to high-speed data transmission. More specifically, even when devices that are inter-connected via cables are in different data transmission environments, at least one optimized link connection is set up between devices to ensure compatibility between new and existing devices.
