TCP TLS Goodput

Name: tcp-tls-goodput

Description

'tcp-tls-goodput' is identical to 'tcp-goodput', except it supports the TLS protocol, ensuring data privacy and data integrity.

Note: Mapago - a Go implementation of maparo - currently supports TLS 1.2.

Features

• Payload pattern: zeroized, random ASCII, full rand (client side)
• Configurable DSCP value (if OS support, client side)
• Flexible traffic exchange configuration possibilies
• Setting No Delay
• Setting Maximum Segmet Size
• Goodput Limit configuration support. For TCP this is somewhat hacky. Especially for high data rates the userspace interaction can limit the overall system performance. So consider this feature as experimental
• Zerocopy mode uses snedfile (if OS support). Will not work in all other configuration options
• IPv6 flowlabel support
• Selectable congestion control algorithm
• Parallel Workers (thread support)

Name

This module is standardized with the name:

Info Reply

tcp-tls-goodput has no additional information for the client. The tcp-tls-goodput dictionary MUST be empty.

E.g.

[]
  "id" : "hostname=uuid",
  "seq-rp" : <uint64_t>
  "modules" : {
     "tcp-tls-goodput" : { "cores" : <uint64_t> },
  }
[]

Not Supported

• Ignore seconds from start of measurement. This must be done by analysis tooling
