Exploring delay-based tcp congestion control

The thesis begins with a short review of TCP and new congestion control schemes in Chapter 2. Following this, chapter 3 explores the question of whether correlation between congestion and the delay signal of each flow on a link is really necessary for delay-based congestion control to function. It also explores the behaviour of the delay-based AIMD (DB-AIMD) algorithm in various network environments. Chapter 4 presents an experimental study into the effectiveness of a particular delay-based methodology for emptying network queues where congestion is detected. Finally, chapter 5 discussed some practical issues involved in how one measures RTT in practice for the purposes of congestion control

Spectral FRET analysis of the GFP and RFP intensities. Primary neurons were transfected with GFP-PS1 (negative FRET control, n = 12 cells), RFP-GFP fusion (R-G, positive FRET control, n = 24) or GFP-PS1-RFP (PS1 conformation FRET probe, n = 10). The GFP was excited by argon laser at 488 nm wavelength, and the emission intensities of GFP and RFP within the 513 ± 10.57 nm and 598 ± 10.57 nm spectral bandwidth of the Metadector, respectively, were collected every 3 minutes for the duration of 33 minutes (middle and bottom graphs, respectively). The arrow indicates the time point of 50 mM KCl stimulation. No significant change in the GFP or RFP fluorescence emission intensity (no photobleaching), or the R/G ratio was observed in the G-PS1 and R-G transfected cells. The change in the R/G ratio after KCl stimulation was detected only in G-PS1-R transfected cells due to increased FRET efficiency/change in PS1 conformation. The black line shows mean ± SEM values.
