💖 NFD ASF strategy — nfd-asf-strategy 💖

Okay bestie, this is the manual page for NFD-A...ATEGY(7) from the Named Data Networking Forwarding Daemon (NFD) set — manual-name moment folded in right here at the top, no cap. It's giving nfd-asf-strategy, and it's here to explain ASF: Adaptive Smoothed RTT-based Forwarding Strategy. 🦋

✨ NAME ✨

nfd-asf-strategy — NFD ASF strategy 💅

🌈 SYNOPSIS 🌈

The vibe is literally:

nfdc strategy set prefix NAME strategy
/localhost/nfd/strategy/asf[/v=5][/probing-interval~INTERVAL][/max-timeouts~TIMEOUTS]

💫 DESCRIPTION 💫

ASF is an Adaptive Smoothed RTT-based Forwarding Strategy that chooses the best next hop based on SRTT measurements, and also periodically probes other next hops to learn their RTTs. It's main-character energy for path selection: measure, smooth, probe, slay. ✨

🎀 OPTIONS 🎀

  • probing-interval <INTERVAL> — this optional parameter tells ASF how often to send a probe to determine alternative paths. The value is specified in milliseconds (a non-negative integer). Smaller values will result in higher overhead but faster reaction. The default value is 1 minute and the minimum value is 1 second. 🕐
  • max-timeouts <TIMEOUTS> — this optional parameter makes ASF switch to another appropriate face (if available) after it has encountered the specified number of timeouts. The value is a positive integer and defaults to 3, i.e., switch to another face after 3 timeouts. Smaller values make ASF more sensitive to timeouts and will switch paths more frequently, which should provide a faster reaction to link failures. Larger values may be better suited when transient timeouts are common and for certain application uses. 💀

🍓 EXAMPLES 🍓

  1. Use the default values for all parameters.
nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf
  1. Set the probing interval to 30 seconds.
nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/v=5/probing-interval~30000
  1. Set the maximum number of timeouts to 5.
nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/v=5/max-timeouts~5
  1. Set the probing interval to 30 seconds and the maximum number of timeouts to 2.
nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/v=5/probing-interval~30000/max-timeouts~2
  1. Set the retransmission suppression multiplier to 2.5 and the probing interval to 45 seconds. See nfdc-strategy(1) for more information on the retransmission suppression parameters.
nfdc strategy set prefix /ndn strategy /localhost/nfd/strategy/asf/v=5/retx-suppression-multiplier~2.5/probing-interval~45000
