TCP congestion control has been the subject of significant research for more than two decades. Various algorithms including TCP Tahoe, TCP Reno. TCP NewReno. SACK. FACK. and their variations have been proposed to overcome the problem of network congestion and increase network utilizmion. The TCP Vegas algorithm has been extensively debated in recent years. TCP Vegas' behavior in the presence of...

TCP (Transmission Control Protocol) is the main transport protocol used in high speed network. In the OSI Model, TCP exists in the Transport Layer and it serves as a connection-oriented protocol which performs handshaking to create a connection. In addition, TCP provides end-to-end reliability. There are different standard variants of TCP (e.g. TCP Reno, TCP NewReno etc.)which implement mechani...

In high-speed and long-distance networks, TCP NewReno, the most popular version of Transmission Control Protocol (TCP), cannot achieve sufficient throughput owing to the inherent nature of the congestion control mechanism of TCP. Therefore, in order to overcome this limitation, Compound TCP was proposed. Compound TCP can achieve a considerably higher throughput than TCP NewReno in high-speed an...

In this work, we investigate the bandwidth and transfer time of long-haul TCP versus cascaded TCP [5]. First, we discuss the models for TCP throughput. For TCP flows in support of bulk data transfer (i.e., long-lived TCP flows), the TCP throughput models have been derived [2, 3]. These models rely on the congestion-avoidance algorithm of TCP. Though these models cannot be applied with short-liv...

background: some types of implants used for orbital implantation have side effects and complications. in this study we have evaluated beta-tricalcium phosphate (ß-tcp: chronos) granules as an orbital implant.   methods: eighteen rabbits randomly allocated to four groups. right eye enucleation performed in groups i to iii followed by filling with autologous bone particles (n=5), a mixture of aut...

We present a new end-to-end transport protocol called Multipath Transmission Control Protocol (M/TCP) and its robust acknowledgement (ACK) schemes. M/TCP is designed as an alternative TCP option to improve reliability and performance of today’s Internet. M/TCP allows a sender to simultaneously transmit data via multiple controlled paths to the same destination. The protocol requires no modifica...
