Introduction:Visualization of inner ear structures is a valuable strategy for researchers and clinicians working on hearing pathologies. Optical coherence tomography (OCT) is a high-resolution imaging technology which may be used for the visualization of tissues. In this experimental study we aimed to evaluate inner ear anatomy in well-prepared human labyrinthine bones.Materials and Methods:Thr...

We are working on a modification to TCP’s window increase/decrease algorithm that would allow TCP to run with high congestion windows with realistic packet drop rates. TCP’s sending rate is roughly 1:2=pp packets per round-trip time, for p the packet loss rate on the path. This is a direct consequence of TCP’s halving its congestion window in response to loss, and increasing the congestion wind...

In this paper we consider optimal congestion control and routing schemes for multipath networks with non-congestion related packet losses which can be caused by, for example, errors on links on the routes, and develop a relaxed multipath network utility maximization problem. In order to obtain the optimum, we present a primal algorithm which is shown to be globally stable in the absence of roun...

The main reason for network congestion is using TCP/IP protocol for transmission. In this paper, the technique called bandwidth estimation is used to avoid congestion in the network which uses TCP/IP protocol mechanism. It finds out the equilibrium point of the window and then the size of the window is adjusted in a round trip time. Initially the TCP and Active Queue Management technique is dis...

Satellite networks are going to play an important role in the global information infrastructure. Satellites can be used to provide Internet services to fixed users and to mobile users. However, recent measurements show that the satellite link efficiency is only about 30%. In order to improve the performance of Internet over satellite, a new protocol called Receiver Window Backpressure Protocol ...

As multicast applications are becoming more common, multicast congestion control has become an important problem. In this paper, we present an architecture for multicast congestion control schemes. We identify three components that constitute this architecture: namely, the feedback consolidation mechanism, the round-trip time measurement mechanism, and the loss detection and timeout mechanism. ...

product, xC RTT , where RTT is the average round trip time, and C the link capacity. Subsequent work has shown that these buffer sizes are over-provisioned. Current implementations of operating systems set a maximum congestion window size of between 10 (in Windows XP) to 40 (in Linux 2.4 and 2.6). In addition, many Internet flows today are short-lived, and end with the packets still buffered in...
