New Slide for BBR | |
Dear students, During the last lecture, I explained again why increasing cwnd beyond the optimal value (path's bandwidth-delay product) does not increase the available throughput/bandwidth, but increase the delay linearly (as shown by the graph in slide 191). For your convenience, and for those who did not attend the lecture, here is a slide that summarizes this discussion: https://drive.google.com/file/d/1fHh_6pkiGxB0DkDRHJkfs7mjTYCyv2R7/view?usp=sharing Reuven |

סטודנטים יקרים שלום, להלן מס הבהרות לשאלה 5 Mininet TCP lab 1. בסכמת הטופולוגיה של סעיף b – נפלה טעות ב bandwidth של הקו בין s1 ל s2. צ"ל: 100Mbps 2. הפלת הקו בין s1 ל s2 : ניתן לבצע ע"י פתיחת טרמינל לאחד הסוויצים (השתמשו בכפתורים המתאימים ב GUI ) ואז הורדת \ העלאת הקו המתאים ע"י שימוש בפקודתifconfig . לדוגמא: sudo ifconfig eth1 down sudo ifconfig eth1 up 3. גרפים נדרשים לכל טופולגיה: עבור כל פרמטר יש לשלב בגרף אחד תוצאות כל ה hosts (בצבעים שונים כמובן). 4. גרפים ניתן לייצר ב Excel – לאחר יבוא קובץ הפלט אליו. 5. חישוב ssthreshold : יש לחשבו לפי ההגדרה ב RFC8312 במקרה של duplicate ACKs או network congestion , כאשר beta_cubic=0.7 ssthresh = cwnd * beta_cubic; // new slow-start threshold ssthresh = max(ssthresh, 2); // threshold is at least 2 MSS בברכה, צוות הקורס |

Slide 217 | |
Dear students, There were several questions regarding slide 217 (the spin bit algorithm), so I believe the description and the figure are not clear enough. I refer you to the illustration in section 3.2 of https://britram.github.io/draft-trammell-quic-spin/twopoint/draft-trammell-quic-spin.html It shows the algorithm using many figures, and it is therefore clearer than my description.

BBR code Update | |
Dear students, As explained during today's lecture, I decided to simplify the presented BBR code by not discussing the case that the receiver is "application limited". Therefore, we assume that the application always has data to send, and this is up to BBR when to transmit a new packet. For the revised code, we need to remove some lines, as you can see in the up-to-date slides in https://drive.google.com/file/d/1RYvlKzDg3XCwiRpHUAxSRZr1I9SrLeu6/view?usp=sharing . You can also ignore cwnd_gain in slide 195, which is a constant between 0 and 1 that determines how aggressive (close to 1) BBR is. Reuven |
