Niceperf

Basically iperf but with a few quality of life improvements performance tool.

TODOs

Latency

• icmp ping (similar to ping)
  • For ICMP we need both ip seqnr and an internal counter which does not wrap in the lifetime of the measurement
  • freqency of the measurement should be configurable
  • payload size should be configurable as well configuration that includes underlaying protocol headers (ipv4, ipv6)
  • output must include timestamp
  • ability to bind to a specific interface
  • amount of infligt pings should be configurable
  • IPv6 support
  • max count of pings should be configurable
  • timeout of pings should be configurable
• udp echo
  • Need own seqnr in packet
  • freqency of the measurement should be configurable
  • payload size should be configurable as well configuration that includes underlaying protocol headers (ipv4, ipv6)
  • output must include timestamp
  • ability to bind to a specific interface
  • amount of infligt pings should be configurable
  • IPv6 support
  • max count of pings should be configurable
  • timeout of pings should be configurable
  • ACK frequency should be configurable.
• tcp echo (for congestion control etc...)
  • Need own seqnr in packet
  • Configurable congestion control algorithm
  • MSS should be configurable
  • Payload size should be configurable
  • freqency of the measurement should be configurable
  • TCP_NODELAY should always be sess
• OWD (one way delay)
  • TBD potenially take a look at Media over quic RFC.
• Output should be in a easily parsable format (json, bson (maybe))
• Configuration should happen via a cli or config file (json) POTENTIALLY multiple tests defined in one config file

Throughput

• TCP throughput

  • Configurable congestion control algorithm

  • MSS should be configurable

  • Payload size should be configurable

  • bandwidth target should be configurable

  • pacing timer

  • multiple streams

  • Application level jitter

  • reporting interval should be configurables

  • bind to specific interface

  • port/ip address should be configurable

  • output: throughput, retransmissions, congestion window, application jitter.

• UDP throughput

  • Payload size should be configurable

  • pacing timer

  • bandwidth target should be configurable

  • reporting interval should be configurables

  • jitter

  • bind to specific interface

  • port/ip address should be configurable

  • output: throughput, jitter, loss, out of order.

• QUIC throughput

  • Configurable congestion control algorithm

  • MSS should be configurable

  • Payload size should be configurable

  • bandwidth target should be configurable

  • pacing timer

  • multiple streams

  • Application level jitter

  • reporting interval should be configurables

  • bind to specific interface

  • port/ip address should be configurable

  • both support of stream and datagram.

  • output: throughput, retransmissions, congestion window, application jitter.

• the control channel should be configurable to i.e another port or even ip address

• affinity to specific cores should be configured via e.g. taskset

Additional Notes

• iperf fq-rate is not the same as the actual throughput?
• enable/disable of nagle algorithm
• set don't fragment bit on ipv4 headers
• get server output iperf?
• server addrress should be public ip/reachable from outside
• In case of udp reply to the same address as the request came from
