The emergence of cloud data centers has led to the design of customized transport protocols such as Data Center TCP (DCTCP). These protocols improve the performance of cloud applications by explicitly accounting for the unique network and traffic characteristics in data centers. However, s u c h protocols have only been evaluated under greenfield deployment scenarios, where the entire data center...
Satellite communication has become important in the current global data communication due to its large coverage area. Satellite links are affected by two major concerns: long propagation delays, and relatively high error rates. Standard TCP congestion control variants were not designed to address these challenges. They generally depend on round trip times (RTTs), and hence suffer heavily if the RTTs...
The congestion control mechanism TFRC, which is widely used in current real-time streaming media, is analyzed in this paper. A proposal aiming at the requirement for smoothly change of transmit rate as well as short delay and jitter of real-time streaming media has been made that adjusting the transmit rate of the sender to the change of single trip delay jitter. In the meanwhile, a dynamic adaptive...
