generate

Generate next FTP, On-Off, VoIP, or video conference application traffic packet

Syntax

[dt,packetSize] = generate(cfg)

[dt,packetSize] = generate(cfg,elapsedTime)

[___,packet] = generate(___)

Description

[dt,packetSize] = generate(cfg) generates the next FTP, On-Off, VoIP, or video application traffic pattern based on the specified configuration object, cfg. The object function returns the time remaining to generate the next packet, dt, and the size of the current packet, packetSize.

[dt,packetSize] = generate(cfg,elapsedTime) specifies the time elapsed, elapsedTime, since the previous call of this object function.

[___,packet] = generate(___) returns the FTP, On-Off, VoIP, or video application traffic packet. Specify an argument combination from any of the previous syntaxes.

Examples

Generate VoIP Application Traffic Pattern Without Jitter

Create a VoIP application traffic pattern object, disabling modeling of jitter.

cfgVoIP = networkTrafficVoIP('HasJitter',false);

Generate a VoIP application traffic pattern.

[dt,packetSize] = generate(cfgVoIP); 

Input Arguments

cfg — Configuration object to generate FTP, On-Off, VoIP, or video application traffic pattern

networkTrafficFTP object | networkTrafficOnOff object | networkTrafficVoIP object | networkTrafficVideoConference object

Configuration object to generate FTP, On-Off, VoIP, or video application traffic pattern, specified as a networkTrafficFTP, networkTrafficOnOff, networkTrafficVoIP, or networkTrafficVideoConference object.

elapsedTime — Time elapsed since previous call of this object function

nonnegative scalar

Time elapsed since the previous call of this object function, specified as a nonnegative scalar. This argument must be expressed in milliseconds.

Data Types: double

Output Arguments

dt — Time remaining to generate next packet

nonnegative scalar

Time remaining to generate the next packet, returned as a nonnegative scalar. This argument must be expressed in milliseconds.

Data Types: double

packetSize — Size of current packet

positive scalar

Size of the current packet, returned as a positive scalar. The units of this argument are in bytes.

Data Types: double

packet — Application data packet

column vector of integers in the range [0, 255]

Application data packet, returned as a column vector of integers in the range [0, 255]. This value contains the application data specified by the ApplicationData property of the input cfg. If the ApplicationData property is not specified, packet is a column vector of 1s.

Dependencies

To enable this output argument, set the GeneratePacket property of the input cfg to 1 (true).
