Discussion

• tuexen discussed how to mitigate blackhole detection problems
  • Action item:
    • tuexen@ will commit change to allow an administrator to commit a fixed value. The used value will be max(current calculate value, fixed value). Therefore, a fixed value of 0 will maintain the current behavior. Update: Harder than initially thought.
    • tuexen@ will tweak pmtud_blackhole_detection such that 0 means disabled, 1 means enabled for IPv4 and IPv6, 2 means enabled only for IPv4, 3 means enabled only for IPv6.
• Discussed how one can increase the TCP receive buffer size
• dummynet has buffer limits, which are limiting satellite communication emulations. thj@ will look into this.
• Availability of Black Box logging tools have been discussed. @thj will make them available after getting them from rrs@.

Next meeting: 9 April @ 1400 UTC
