RatedSource Element Documentation

NAME

RatedSource — Click element; generates packets at specified rate

SYNOPSIS

RatedSource([DATA, RATE, LIMIT, ACTIVE, KEYWORDS])

Batching: Batching natively supported
Ports: no inputs, 1 output
Processing: agnostic

DESCRIPTION

Creates packets consisting of DATA, emitting at most LIMIT such packets out its single output at a rate of RATE packets per second. When used as a push element, RatedSource will send a maximum of one packet per scheduling, so very high RATEs may not be achievable. If LIMIT is negative, sends packets forever. Will send packets only if ACTIVE is true. Default DATA is at least 64 bytes long. Default RATE is 10. Default LIMIT is -1 (send packets forever). Default ACTIVE is true.

Keyword arguments are:

  • DATA — String. Same as the DATA argument.
  • LENGTH — Integer. If set, the outgoing packet will have this length.
  • RATE — Integer. Same as the RATE argument.
  • BANDWIDTH — Integer. Sets the RATE argument based on the initial outgoing packet length and a target bandwdith.
  • LIMIT — Integer. Same as the LIMIT argument.
  • HEADROOM — Integer. Sets the amount of headroom on generated packets. Default is the default packet headroom.
  • ACTIVE — Boolean. Same as the ACTIVE? argument.
  • STOP — Boolean. If true, then stop the driver once LIMIT packets are sent. Default is false.

To generate a particular repeatable traffic pattern, use this element's rate and active handlers in conjunction with Script.

EXAMPLES

  RatedSource(\<0800>, 10, 1000) -> Queue -> ...

ELEMENT HANDLERS

  • count (read-only) — Returns the total number of packets that have been generated.
  • reset (write-only) — Resets the number of generated packets to 0. The RatedSource will then generate another LIMIT packets (if it is active).
  • data (read/write) — Returns or sets the DATA parameter.
  • length (read/write) — Returns or sets the LENGTH parameter.
  • rate (read/write) — Returns or sets the RATE parameter.
  • limit (read/write) — Returns or sets the LIMIT parameter. Negative numbers mean no limit.
  • active (read/write) — Makes the element active or inactive.
