Configuration

alt text

In this experiment, we have 2 groups, each group has 5 hosts, and one more switch.

In this scenario, host0/1/4/5/6 form group1 (in red), host2/3/7/8/9 form group2 (in black) and host10 is a switch.

In each group, we have to let CoS-1 flows generated from different hosts towards different destinations to avoid the interference. Besides, CoS2-7 flows generated from different hosts must arrive at the same destination to make it easier to generate congesting queues.

  • topology: 10 hosts (2 groups, each group has 5 hosts), 1 switch
  • link: 100Gbps, 2us
  • running duration: 2s
  • flow generating duration: 1s
  • CC: DCQCN / HPCC / PowerTCP
  • buffer: 16MB
  • total reserve: 3,072B * 32(16) * 7
  • total insurance headroom: 56,840B * 32(16)port (DSH), 56840B * 32(16)port (DSHnoSH), 56840B * 32(16)port * 7pg (Normal)
  • mmu: DSH / DSHnoSH / SIH
  • DT alpha: 1/16
  • burst size: 64KB x 2 x 2 (2 groups, each one has 2 bursty flows)
  • flow intro: background flow (CoS: 1, load: 0.2, mode: web-search) + bursty flow (CoS: 2-7, total load: 0.2-0.8, each vary from 0.2/6 to 0.8/6, mode: bursty)
  • flow configuration: (We use "->" to replace "towards" here)
    • background flow:
      • Group1: host0 -> host4 | host1 -> host5
      • Group2: host2 -> host7 | host3 -> host8
    • bursty flow:
      • Group1: host0 -> host6 | host1 -> host6
      • Group2: host2 -> host9 | host3 -> host9

flow details is listed here

name CoS load mode gen_time flow_size src & dst
background flow 1 0.2 web-search start: 3s, end: 5s, poisson distribution (interval follows exponential distribution) Generate random samples based on the web-search flow distribution values Group0: host0 -> host4, host1 -> host5; Group1: host2 -> host7, host3 -> host8
bursty flow 2-7 0.2-0.8 (for each flow must be divided by 6 based on this) bursty start: 3s, end: 5s, poisson distribution (interval follows exponential distribution) fixed size, called burst_size in code Group0: host0 -> host6, host1 -> host6; Group1: host2 -> host9, host3 -> host9
