In the existing SCTP, an association is established by exchanging four initial chunks during four-way handshakes. What is serious is that the association establishment phase has to be backed off exponentially once any initial chunk gets lost or suffers random bit errors. This will result in a severe performance degradation of SCTP over wireless networks due to a very long waiting time. In order to...
Forward error correction (FEC) scheme has dual side-effects on the throughput performance for the satellite networks. One is to consume some extra bandwidth to send redundant information, and the other is to disable the corruption-aware TCP variants to differentiate the corruption events from the loss events. This may result in significant throughput jitter while satellite channel is in an unsteady...
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...
Stream control transmission protocol (SCTP) uses a checksum in the common header for each packet, by which a corrupted SCTP packet will be regarded as a loss. This letter proposes a new "chunk checksum" scheme for SCTP, in which each data chunk contains its own checksum field to determine a corruption of data chunk. Simulation results show that the proposed scheme could improve the throughput...
