This paper describes an active attack against the Transport Control Protocol (TCP) which allows a cracker to redirect the TCP stream through his machine thereby permitting him to bypass the protection o ered by such a system as a one-time password [SKEY] or ticketing authentication [Kerberos]. The TCP connection is vulnerable to anyone with a TCP packet sni er and generator located on the path ...

Abstract—In this document, we introduce CapStart TCP, an adaptive Slow Start scheme that consistently achieves fast TCP file transfer times regardless of high speed network scenario. Once the TCP session is established, we estimate TCP session path capacity scenario, and tune the transport protocol to deliver fast transfer times. We show that our capacity estimator works well even when the sess...

Preamble The 20th century has seen the digital revolution, introducing the change from analog to digital technology. It is continuing right into the 21st century, interconnecting billions of digital devices over the Internet. Different types of devices and ways of communication have been designed. From smartphones to personal computers; from small servers connected to the Internet to huge conte...

IP networks were designed to provide general connectivity. At their advent, routing methods focused only on finding one optimal path between given endpoints. Although many solutions to sending traffic via multiple paths have appeared over time, the majority of current IP networks are still managed to support only single-path transmissions. This survey examines various approaches which can provi...

We introduce CTCP, a novel multi-path transport protocol using network coding. CTCP is designed to incorporate TCP’s good features, such as congestion control and reliability, while improving on TCP’s performance in lossy and/or dynamic networks. CTCP builds upon the ideas of TCP/NC introduced by Sundararajan et al. and uses network coding to provide robustness against losses. We introduce the ...

Best-effort traffic has been the dominant traffic type in the Internet, and TCP has been playing the major role for carrying such traffic. Today, Internet is again moving toward more reliable and robust network services including QoS. Provisioning multiple paths as backup routes is one of the feasible solutions to designing fault-tolerant network. When multiple paths are selected, traffic trans...

The emergence of OpenFlow and Software Defined Networks brings new perspectives into how we design the next generation networks, where the number of base stations/access points as well as the devices per subscriber will be dramatically higher. In such dense environments, devices can communicate with each other directly and can attach to multiple base stations (or access points) for simultaneous...

This report examines potential stability problems associated with a model based apporach to TCP-friendly ow control for non-TCP traac. In speciic, such an approach involves using a TCP-friendly formula that estimates the throughput of a TCP session with the same end-to-end traac characteristics as the non-TCP connection under consideration. The inputs to this formula include the round trip time...

Many previous papers have pointed out that TCP performance in multi-hop ad hoc networks (MANETs) is sub-optimal. This is due to several TCP design principles that reflect the characteristics of wired networks dominant at the time when TCP was designed that do not hold in MANETs. Based on this evidence, several TCP variants have been proposed in the literature. However, little effort has been de...

In this paper we present a new AIMD congestion control algorithm, H-TCP, that is suitable for deployment in high speed and long distance networks as well as conventional networks. H-TCP generalises the AIMD strategy to significantly improve the manner in which responsiveness and efficiency scale with path bandwidth-delay product and level of queue provisioning within the network. The performanc...
