A Model for Detecting Transport Layer Data Reneging
نویسندگان
چکیده
Data reneging occurs when a data receiver first SACKs data, and later discards that data from its receiver buffer prior to delivering it to the receiving application or socket buffer. Today’s reliable transport protocols such as TCP and SCTP are designed to tolerate data reneging. We argue that this design assumption is wrong, in part based on a hypothesis that data reneging rarely if ever occurs in practice. To support our hypothesis, we present a model for detecting instances of data reneging by analyzing traces of TCP traffic. Using this model, we will investigate the frequency of data reneging in Internet traces provided by CAIDA. KeywordsData Reneging; SACK; SCTP; TCP

Transport layer reneging
Reneging occurs when a transport layer data receiver first selectively acks data, and later discards that data from its receiver buffer prior to delivery to the receiving application or socket buffer. Reliable transport protocols such as TCP (Transmission Control Protocol) and SCTP (Stream Control Transmission Protocol) are designed to tolerate reneging. We argue that this design should be chan...
متن کاملDetecting Bot Networks Based On HTTP And TLS Traffic Analysis
Abstract— Bot networks are a serious threat to cyber security, whose destructive behavior affects network performance directly. Detecting of infected HTTP communications is a big challenge because infected HTTP connections are clearly merged with other types of HTTP traffic. Cybercriminals prefer to use the web as a communication environment to launch application layer attacks and secretly enga...
متن کاملDiffusion Process for GX/G/M Queuing System with Balking and Reneging
In the present investigation transient, G x/G/m queuing model with balking and reneging has been studied. The diffusion process with elementary return boundary has been used for modeling purpose. The probability density function (p. d. f.) for the number of customers in the system has been obtained. In special case, the steady state results that tally with those of Kimura and Ohsone have been e...
متن کاملDetecting Depression in Elderly People by Using Artificial Neural Network
Introduction: The possibility of depression is common in the elderly. Novel technologies allow us to monitor people related to depression. Hence, a model was provided to detect depression in elderly based on artificial neural network (ANN). Methods: The present study is an applied descriptive-survey research. Forty elderly people were randomly selected from the Elderly Care Center in Gonbad Ka...
متن کاملNumerical Simulation of Separation Bubble on Elliptic Cylinders Using Three-equation k-? Turbulence Model
Occurrence of laminar separation bubbles on solid walls of an elliptic cylinder has been simulated using a recently developed transitional model for boundary layer flows. Computational method is based on the solution of the Reynolds averaged Navier-Stokes (RANS) equations and the eddy-viscosity concept. Transitional model tries to simulate streamwise fluctuations, induced by freestream turbulen...
