BackgroundPrevious studies have indicated an association between psoriasis and inflammatory bowel disease (IBD), and the concurrence of the two diseases reportedly has higher morbidities in Caucasian populations. However, reports on the concurrence of psoriasis with IBD in the Asian population in the literature are scarce.
ObjectiveTo analyse the characteristics of psoriasis concurrent with IBD and...
Generally only individual regions suffer bit errors as a packet travels a lossy channel. At the receiver side, however, the entire packet has to be discarded even if only one bit is erased. This may result in degradation of the throughput performance of stream control transmission protocol (SCTP) over wireless networks with high bit error rate. This paper proposes a dynamic partial cyclic redundancy...
Satellite link is generally featured by long propagation delay, large bandwidth-delay product (BDP) and high bit error rate (BER). This tends to make the conventional TCP suffer from performance degradation in satellite networks. Thus Forward Error Correction (FEC) scheme is suggested for error recovery over satellite channel and RFC 2488 suggests that TCP does not reduce its congestion window (cwnd)...
Stream Control Transmission Protocol (SCTP) uses an overall checksum scheme for each segment, by which a corrupted packet will be regarded as a lost one. This may result in degradation of SCTP's throughput performance over wireless networks. This paper proposes a hierarchical checksum scheme for SCTP, in which several checksum fields are distributed within a segment for different coverages. The main...
This paper proposes a new error and congestion control scheme using corruption-aware adaptive increase and adaptive decrease algorithm to improve TCP performance over wireless/heterogeneous networks. In the proposed scheme, the slow start threshold is estimated based on the amount of the received integral data as well as the amount of the received corrupted data as per round trip time interval, and...
The enhanced communications transport protocol (ECTP), which has been standardized in the ISO/IEC JTC1/SC6, is an end-to-end multicast transport protocol that is designed to support interactive Internet multicast applications with unicast backward channels to the multicast sender. This paper describes the design, implementation and experimental results for the ECTP protocol.
