摘　　要：A traffic management scheme in serial RapidlO （SR10） interconnect is proposed to deal with the performance degradation caused by noise and electromagnetic interference （EMI）, which is generated by hardly avoidable errors of hardware implementation and tough working environment. The main idea of this scheme includes adaptive speed transition and freeze-acknowledgement （freeze-ACK）. Adaptive speed transition can improve throughput and reduce delay in high bit error rate （BER） environment. Simultaneously, freeze-ACK is adopted to conquer frequent usage of feedback channel. Simulation shows that the scheme of combining adaptive speed transition with freeze-ACK offers great performance improvement in SRIO network.A traffic management scheme in serial RapidlO （SR10） interconnect is proposed to deal with the performance degradation caused by noise and electromagnetic interference （EMI）, which is generated by hardly avoidable errors of hardware implementation and tough working environment.
