The main challenge in the field of designing multimedia services is the integration and support of a wide variety of applications. Quality of Service(QoS) provides a unifying theme on which the functions and facilities of the open system standards can be constructed. In distributed multimedia system, QoS guarantees are fundamentally concerned with the end-to-end communication between applications. One of the important QoS parameters is the reliability of the transfer. Including SCTP(Stream Control Transport Protocol), conventional error control mechanisms, however, do not consider the integrated viewpoint of multimedia data. In paper[1], We have designed and proposed the multimedia oriented error control method based on multimedia characteristics called ECMC(Error Control based on Multimedia Characteristic). In this paper, We have investigated its transfer delay. The results show that the ECMC mechanism manifests superior performance as errors occur more frequently. When the frame transfer succeeds, it can be found that the ECMC mechanism reveals shorter average frame delay than SREC(Selective Repeat Error Control). On the other hand, the performance measurements on the both mechanisms show closer results as the error rate decreases. Furthermore, in the case of the extremely low error rate, the both mechanisms represent the almost same performance results. Therefore, it makes SCTP have the flexibility and high performance. It should have the reduction effect of the communication resources as well as satisfy the requirements of users. |
