First-come-first-served packet dispersion and implications for TCP
نویسندگان
چکیده
We study the packet dispersion phenomenon that a traffic flow experiences when it passes through a router. We show that when there are competing flows and the router schedules packets first-come-first-served (FCFS), the dispersion is not described well by the bottleneck spacing effect. We therefore introduce the term FCFS-spacing effect. We also show that for a router implementing weighted fair queuing, dispersion is due either to the bottleneck spacing effect or the FCFS spacing effect. Finally, we discuss the implications of FCFS packet dispersion on TCP’s self-clocking mechanism.

New High Secure Network Steganography Method Based on Packet Length
In network steganography methods based on packet length, the length of the packets is used as a carrier for exchanging secret messages. Existing methods in this area are vulnerable against detections due to abnormal network traffic behaviors. The main goal of this paper is to propose a method which has great resistance to network traffic detections. In the first proposed method, the sender embe...
متن کاملAdaptive scheduling in DOCSIS-based CATV networks
This paper studies the effect of the DOCSIS MAC layer on the performance of two-way TCP transfers in Hybrid Fiber Coax (HFC) networks. We propose a new adaptive scheduling scheme called Long Packet Deferment (LPD) at the headend to improve TCP performance in DOCSIS-based HFC networks. LPD reduces the frequency of transmission of long packets and, if such long packets are transmitted, they are s...
متن کاملLinkWidth: A Method to measure Link Capacity and Available Bandwidth using Single-End Probes
We introduce LinkWidth, a method for estimating capacity and available bandwidth using single-end controlled TCP packet probes. To estimate capacity, we generate a train of TCP RST packets “sandwiched” between two TCP SYN packets. Capacity is obtained by end-to-end packet dispersion of the received TCP RST/ACK packets corresponding to the TCP SYN packets. Our technique is significantly differen...
متن کاملImproving Bandwidth-power Efficiency of Homogeneous Wireless Networks Using On-meet Threshold Strategy (RESEARCH NOTE)
Over two decades, a problem of location dependent has been focused for improving the communication Bandwidth-Power Efficiency of homogeneous networks. The efficiencies of communication links are weakened by the Hidden Terminal Problem. Thus we propose a Fine – Tune Strategy for analyzing the On-Off communication region. We were observed that the proposed technique had been able to track and mo...
متن کاملEffects of time, temperature and precursor on solid state synthesis of α-TCP
The effects of solid state synthesis process parameters (time and temperature) and primary calcium precursor on the amount of produced α-tricalcium phosphate (Ca3(PO4)2 or α -TCP) have been investigated. α-TCP was synthesized by firing of stoichiometric amount of calcium carbonate and monetite in first group and calcium carbonate and brushite in the second group, once at 1350°C for 3,6,8,16 h d...
